I made several gardens at various schools while working as a primary school teacher, but the 
most successful have always been when students and the wider community have been involved in 
the process. Gardens are a fabulous context for learning and a great way for students and their 
whanau to learn the cycles of the seasons and how to grow their own food. They provide an 
opportunity to find out about the importance of improving soil, various composting methods, 
heritage seeds, interdependence, biodiversity, nutrition and health. Gardens also offer a chance 
for communities to work together, learn from one another and share seeds, plants, kai and 
recipes!

1: Ideas and Issues for School Gardens 
Gardening is Easy! 
You don’t need to have ‘green thumbs’ to start gardening. If you are a novice, just start with a 
small plot, and some ‘easy’ plants, such as radish and salad greens. Ask experienced gardeners 
for help and advice. Gardeners love sharing! You will soon find out how fun, easy and satisfying 
gardening is, and nothing tastes better than something harvested straight from the garden! 
Getting Started: Take Time! 
You really need to spend at least one term learning about gardens, before starting your garden. 
Suggested activities for students prior to starting a garden include: 
• Collecting baseline data as to how many families within the school community already 
have gardens at home. This information helps determine gardens to visit and community 
experts. (This survey can be repeated after developing a school garden to see how a school 
garden can impact on the wider community) 
• Learning about different gardening methods (e.g.: no-dig; organic; mulch; ‘traditional’; 
planting by the moon; Māori and Pasifika gardening ) and garden designs (e.g.: 
permaculture; potager; ‘traditional’) 
• Visiting local gardens (may include gardens of family / whanau; community gardens; other 
4 
schools) 
• Learning about plants that grow in your bio-region 
• Developing design ideas for your garden 
• Sourcing funding and / or seeking re-usable materials for your garden 
• Deciding where to locate the garden (see criteria to consider below) 
• Having the soil tested 
• Consulting parents, whanau and the wider community about the garden 
Involve Students 
It is crucial that students are involved in the process as much as possible – this enables them to 
have ownership of the garden, and encourages them to take responsibility for it! Ideally, students 
will have identified a need for, or a desire to develop a garden. This may come about as an 
investigation of their school environment and environmental practices. 
Including Parents, Whanau and the Wider Community 
Successful school gardens often become community gardens, and this can be encouraged by 
giving all community members a role in the garden development. Too often schools rely on the 
same few community members to contribute to projects. One way to overcome this is to have 
students develop a list of things they would like adult help with and then ask all community 
members to contribute in only one way. An example of such a list may include: 
• Loaning a trailer 
• Picking up compost 
• Donating seeds or seedlings
5 
• Collecting mulch 
• Helping unload compost 
• Loaning a shovel 
• Inviting an older community member with gardening expertise 
• Showing students around their personal garden 
Students can also set up rosters for community members, so adults take turn in to contribute to 
the garden as well. 
Link to the Curriculum 
It is vital that any garden project links to students’ learning and the curriculum. Gardens are a 
fabulous context for teaching and learning. A garden provides an authentic context to meet the 
Vision, Principles, Values and Key Competencies of the New Zealand curriculum (Ministry of 
Education, 2007). Many learning areas can be integrated into the context of a garden, including: 
Mathematics - e.g.: measurement when designing; statistics when comparing preferred 
conditions for plants; calculating volumes of compost, mulch materials; estimating number of 
plants required; estimating numbers of seeds on plants; collecting data on rainfall, plant growth 
English – e.g.: writing letters, stories, poems and reports; documenting the process; diary and 
record keeping; reading and researching; asking questions from experts; using the telephone/ 
email/ skype etc to connect with other gardeners (including other school gardeners!); sourcing 
quotes; presenting information about the garden 
Social Sciences – e.g.: why is gardening important to people; different cultures’ gardening 
practices; marketing produce; comparing commercial and home gardening; which plants have 
significance for various cultures; how does gardening contribute to a community 
Health and Physical Education – e.g.: how does healthy soil and food contribute to people’s 
health; which edible plants we can grow in our climate and how do these rate for health benefits; 
minerals and vitamins of various fruit and vegetables; how does establishing a garden contribute 
to the four areas of hauora: taha tinana (physical well-being); taha hinengaro (mental and 
emotional well-being; taha whanau (social well-being); taha wairua (spiritual well-being) 
Technology – e.g.: using appropriate technology (correct tool for the job); designing and creating 
gardening tools (watering cans, weeding tools, irrigation system, rain water harvesting etc.) and 
structures (pest traps, climbing frames for beans, weather stations, compost and worm farms 
etc.) 
Science – e.g.: biodiversity; soils and soil structures; ecosystems; companion planting (i.e. which 
plants grow well alongside others and support them by attracting predatory wasps, supply 
nitrogen etc .); developing and retaining healthy soil; composting; weather monitoring
The Arts – e.g.: sculptures and structures; botanical sketching; natural music and sounds; role 
plays and drama 
Te reo and tikanga Māori – e.g.: Māori names for plants; planting by the moon; cultivation 
methods; traditionally grown plants and tools 
There are also NCEA Education for Sustainability Achievement Standards at Level 2 and 3 now 
which lend themselves very well to an edible gardening project. 
Placement of the Garden 
Out of Sight = Out of Mind! Many school gardens fail because they get forgotten about due to 
their location. Ideally the students will be involved in deciding where to place the school garden. 
Criteria they need to consider include: 
6 
• North facing aspect 
• All day sun 
• Not a student ‘playing area’ 
• Suitable and safe soil 
• Where everyone can see it everyday 
• Protected from pests (rabbits; chooks; sheep etc) 
• Easily accessible by wheelbarrow and / or trailer 
• Near a water source (outside tap; rain harvesting from a roof) 
• Distance to existing large trees (especially oaks and walnuts – which can hinder the growth 
of gardens) 
Garden Edging 
If you have the choice, try to use non-treated timber for garden surrounds. Macrocarpa sleepers 
are ideal for more formal gardens, with child sculptured Oamaru stone, driftwood, bricks and 
rocks excellent for more creative gardens. Old tyres and treated timber can be used, but be 
aware there could be some leaching from these into the soil. It is meant to be minimal, but the 
recommendation is to use these for flowering, rather than edible plants. 
Using Paper and Cardboard in the Garden 
Many people ask about using newspaper and cardboard in a garden, with their inks and glues. 
Some research that suggests that the glues and inks are so minimally damaging for the soil that it 
is not worth being concerned about. And certainly composting these materials are better than 
sending them to landfill, or, arguably, to Asia for recycling. However, in saying that, avoid using 
banana boxes, as they are reputed to be full of harmful sprays. 
Watering 
Seedlings especially need regular watering. Designing and making watering cans, rain water 
harvesting systems or irrigation systems are great ways to enthuse students about getting 
involved. Mulching also greatly reduces the need for watering. Students can test and trial various 
mulches, comparing availability, costs and nutritional value for the soil.
School Holidays 
The Christmas school holidays in particular can be an issue for some schools. Some schools worry 
that everything is harvested during January, while the students are absent. However, as you will 
see in the ‘What to do When’ section of this booklet, there are many vegetables and fruits that 
can be harvested during other months of the year. Watering and weeding may be an issue which 
can be alleviated by mulching and /or irrigation systems, and by developing partnerships with the 
community, some of whom may be happy to help out over January in return for a share in the 
harvest. 
Maintenance 
Once the garden is up and running and students start to focus on other areas of sustainability 
(e.g.: reducing energy use, water conservation, sustainable transport, eco-buildings etc.) it is 
important that the garden is maintained. Some ideas to do this include: 
• Having two representatives (which change weekly) working in the garden with a garden 
7 
facilitator at a certain time each week 
• Classes taking turns for having responsibility for the garden for a certain time 
• Once a week having an ‘environmental project’ time, when students do jobs including the 
garden, alongside others such as managing the worm farm, compost, bokashi buckets, 
paper recycling, other recycling, lost property, monitoring energy use etc. 
• Having parent and whanau ‘working bees’ during school time, and involving students 
• Dividing certain areas of the garden for each class 
• Ensuring that the garden is regularly utilised as a context for learning (see ‘Links to the 
Curriculum’ above) 
What to do with the Harvest 
It is important that students learn what to do with their produce. Ideas include: 
• Giving it as ‘prizes’ or ‘rewards’ to students to take home 
• Classes taking turns to share the harvest 
• Selling fresh produce to the wider community once a week 
• Eating fresh or cooking the produce at school 
• Adding value to the produce (making relish, pickles, herb vinegars etc) and selling these at 
the school fair
2: How to Make a Mulch / No-Dig Garden 
There are several ways to make a mulch or no-dig garden. The process outlined below is relatively 
easy and quick, once you have collected your materials. It has the advantage of not disrupting 
the microlife in the soil, and requires very little weeding or watering. 
8 
1. Mow or flatten the grass if it is long 
2. Create the outline of your garden (use a hose if it is to be curved) 
3. Spread a sprinkling of organic matter – vegetable scraps are ideal – to encourage worms 
4. Cover with 7 layers of damp newspaper (or you could use cardboard) to prevent weeds 
growing through. This layer will eventually rot down so you can take advantage of the soil 
underneath. Don’t use plastic – it doesn’t allow the soil to breathe 
5. Place your garden edging over the newspaper (could be non-treated timber, driftwood, rocks 
or stone) 
4. Add at least 10 cm of composted material. Do not use soil, as there will be weed seeds in it 
5. Mulch over the top with pea straw / lucerne hay / dry leaves / shredded paper etc 
6. Water 
7. To plant seedlings / seeds, part the mulch and plant into the composted material. Keep mulch 
well clear of seeds. 
8. Over time, keep on adding mulch, but use a variety 
9. It will probably take at least 2 seasons before you can grow root crops in a mulch garden.
3: Incredible Edibles for School Gardens 
There is a huge range of incredible edibles that grow in our region. These are some of the basic 
vegetables that grow relatively easily. Apart from tomatoes, they can all be grown outside, 
without too much special care. The trick is to plant them at the right time so they can be 
harvested during the school term (see the What to do When section), although many can be 
grazed on during the year. 
Plants are listed alphabetically by their common names under three sections; vegetables, herbs, 
fruit and nut trees and bushes. Brief descriptions are given, care required, known companions and 
non-companions and uses.

Uses: 
 Deep rooted weeds, such as dock, bring up minerals from the subsoils and make them 
available to other plants and breaking up hard clay pans 
 Weeds conserve nutrients that would otherwise be leached from the ground 
 Weeds add organic matter, improve aeration and contribute water 
 Some weeds are edible, for example: Dandelion, Ferns (pikopiko), Blackberry, Elderberry, 
Sow thistle (Sonchus oleraceus) – young shoots eaten raw or cooked and Nettle – in 
soups and tea (N.B: not the native nettle (Ongaonga or Urtica ferox) which is extremely 
toxic!) 
 Indicative of certain conditions, for example: Chickweed – warming soils in late winter; 
Yarrow – dry, poor soils; Ragwort in paddocks – not grazed by sheep (usually cattle or 
deer paddocks) 
 Beware that some weeds, such as dock, will grow from even the tiniest part of the root 
18 
system! 
 Nearly all weeds can be rotted down in water and made into weed tea

4: What to Do When 
This is a twelve month cycle specifically for the coastal Otago bioregion, but will be relevant for 
parts of Southland as well. It is intended as a guide only and local gardeners in your area will be 
able to assist further. Be aware that climatic patterns contributed to Climate Change result in 
‘false seasons’ and can upset the regular cycle of nature. Furthermore, by creating your own 
microclimate and by placing plants under frost protection, growing seasons can be extended.

5: Liquid Fertilizers, Manures, Mulches 
It is recommended that soils are tested regularly to check which trace elements are missing from 
the soil. To supplement any lacking trace elements, liquid fertilizers, compost, mulches and 
manures can be added to improve soil fertility. 
LIQUID FERTILIZERS 
Animal Manure 
How to make: most animal manures are suitable; steep a sack full in a drum of water for a month 
or so 
How to use: dilute 1:3; refill the drum with water (can steep the same sack full a number of times) 
Comfrey 
How to make: steep a sack full in a drum of water for a month or so 
How to use: dilute 1:2 
Seaweed (sea lettuce is excellent for this) 
How to make: fill drum half full of seaweed; top with water; add a rotten banana to assist the 
decomposition process; wait until everything is liquid 
How to use: use 1 cup diluted in a bucket of water 
Worm Juice 
How to make: collect liquid from a worm farm 
How to use: use 1 cup diluted in a bucket of water 
MANURE 
Animal Manure 
The general rule with animal manure is to allow it to break down for a few months before using in the 
garden. Try to avoid using manure from animals that has been drenched with chemicals. Most 
manure is suitable, with cow manure particularly useful. Be aware that some manure such as chook 
manure is high and nitrogen and too much will produce forked carrots and lots of green growth and 
few flowers (and hence seed) in leguminous plants 
Green Manure 
Green manure is plants grown on unused garden beds and then dug into the soil a couple of months 
before planting the next crop. Leguminous plants are most suitable, such as lupins, beans, clover, 
alfafa (lucerne), but other plants such as nasturtiums, oats and mustard are also useful. 
Wood Ash 
High in potassium and phosphorus, so small quantities are good for root crops. Do not use ash from 
coal or treated timber (Treated timber should not be burned!) 
31
MULCHES 
Pine Needles are an excellent strawberry mulch and around other plants that prefer acidic soil 
eg: blueberries and rhododendrons 
Sawdust can be used as a mulch but robs the soil of nitrogen 
Oak leaves take a long time to break down and are good around shrubs, but avoid as a mulch on 
vegetable gardens 
Other leaves make a good mulch on the vegetable garden 
Pea straw and Lucerne are excellent mulches as they are high in nitrogen, but are expensive if 
they need to be purchased 
Shredded Paper can also be used as a mulch, but needs to be well watered or else it blows 
around in the wind 
Stones make an attractive mulch, and can act as a heat sink, warming the soil. 
32
33 
6: Pest Traps and Sprays 
Pest traps and sprays are considered the ‘last straw’, and are recommended only as a last resort. 
It is much better to spend time improving the soil so that it is healthy and will therefore grow 
healthy plants. Interplanting with a variety of plants (including flowers) and rotating crops can 
also assist in preventing infestations of pests. Some plants such as Queens Anne Lace, parsnips 
and carrots that have gone to seed and other umbelliforous plants, actually attract useful insects 
such as predator wasps that eat pests such as aphids. 
PEST TRAPS 
Beer Trap 
How to make: stale beer in a bottle or container 
How to use: immerse in soil at 45 degrees with opening just over surface, so pests falling in won’t be 
able to escape 
Traps: slugs, snails 
Sugar Traps 
How to make: mix generous amount of sugar with water and cool 
How to use: ¼ fill a bottle, place near house or sheds 
Traps: wasps 
Orange Traps 
How to make: cut an orange in half and place cut side down in the garden 
How to use: in the morning collect pests 
Traps: slugs 
White Cabbage Butterfly Traps 
How to make: soapy water in yellow container 
How to use: place in garden 
Traps: white cabbage butterfly 
MORE ON SLUGS… 
Slugs can be repelled from gardens by broken eggshells, slugs or sawdust sprinkled around plants.
SPRAYS 
Homemade sprays may be stored in sterilized jars. 
Chilli / Red Pepper 
How to make: soak 50g chilli or hot red capsicums in 100ml water for 24 hours; strain and dilute 
1½ tsp in 1litre water; use a little soap as a sticking agent 
Controls: aphids and caterpillars 
Garlic 
How to make: soak 4 cloves of garlic in 1litre of cold water for several days and then blend 
How to use: spray 
Controls: fungus - club root (water down rows in early summer) and pests – red spider; slugs; 
snails 
Lettuce 
How to make: boil in water and strain 
How to use: spray on brassica leaves 
Controls: white cabbage butterfly 
Alternatives: place lettuce leaf on brassicas such as cauliflower 
Milk 
How to make: use 1 part milk to 9 parts water 
How to use: spray at planting time then every 10 days 
Controls: viruses on cucumbers; lettuce; tomatoes 
Pest Tea 
How to make: grind up large numbers of pests and mix with water 
How to use: spray 
Controls: their friends and family 
Soap 
How to make: dissolve 2 tablespoons of pure soap in 1 litre of water, or use bath water or water 
from washing clothes 
How to use: spray 
Controls: white cabbage butterfly, caterpillars, aphids 
Rhubarb 
How to make: boil 500g of rhubarb leaves in 1 litre water (not in an aluminium pan) for 30 
minutes, then cool; dissolve 50g soft soap in 1 litre water and cool; mix the two 
How to use: spray on brassica seedlings; rainwater increases effectiveness 
Controls: aphids; club root 
Alternatives: can use tomatoes stems or stinging nettles instead of rhubarb; can put a rhubarb 
leaf under a seedling when planting instead of spraying NB: Rhubarb leaves are toxic! 
34
Water 
How to use: Hose, with reasonable pressure to knock insects from plants 
Other: add lime to water and apply around beets and cabbages to reduce scab, club root and 
cabbage maggot fly; add salt to water to deter cabbage caterpillars; use warm water for soft 
skinned insects e.g. aphids, caterpillars 
Controls: aphids, caterpillars 
Wormwood Tea 
How to make: 1 tbsp of wormwood leaves in 600ml water and bring to the boil; remove from heat 
immediately 
How to use: when cool, dilute 1 part with 4 parts water and immediately pour around vegetables 
Controls: slugs and snails 
35
7. Heritage and Disease Resistant Varieties 
There is increasing evidence that heritage varieties not only taste better, they are also more disease 
resistant and have higher nutritional value than commercially available fruits and vegetables. Koanga 
Gardens in Northland have conducted research in this field. In addition, seed saved from heritage 
plants will grow true to form as they have not been hybridised. 
36 
When choosing fruit and nut trees consider: 
• appropriateness for your soil and microclimate 
• fruiting times of varieties (early, mid and late) as required – usually a range is best 
• the purpose for the trees (dessert, cooking, juice, forage) 
• availability 
• rootstock

Gardens are a fabulous context for learning and a great way for students and their whanau to learn the cycles of the seasons and how to grow their own food. They provide an opportunity to find out about the importance of improving soil, various composting methods, heritage seeds, interdependence, biodiversity, nutrition and health. Gardens also offer a chance for communities to work together, learn from one another and share seeds, plants, kai and recipes! Tania J.

  • 4. 1: Ideas and Issues for School Gardens Gardening is Easy! You don’t need to have ‘green thumbs’ to start gardening. If you are a novice, just start with a small plot, and some ‘easy’ plants, such as radish and salad greens. Ask experienced gardeners for help and advice. Gardeners love sharing! You will soon find out how fun, easy and satisfying gardening is, and nothing tastes better than something harvested straight from the garden! Getting Started: Take Time! You really need to spend at least one term learning about gardens, before starting your garden. Suggested activities for students prior to starting a garden include: • Collecting baseline data as to how many families within the school community already have gardens at home. This information helps determine gardens to visit and community experts. (This survey can be repeated after developing a school garden to see how a school garden can impact on the wider community) • Learning about different gardening methods (e.g.: no-dig; organic; mulch; ‘traditional’; planting by the moon; Māori and Pasifika gardening ) and garden designs (e.g.: permaculture; potager; ‘traditional’) • Visiting local gardens (may include gardens of family / whanau; community gardens; other 4 schools) • Learning about plants that grow in your bio-region • Developing design ideas for your garden • Sourcing funding and / or seeking re-usable materials for your garden • Deciding where to locate the garden (see criteria to consider below) • Having the soil tested • Consulting parents, whanau and the wider community about the garden Involve Students It is crucial that students are involved in the process as much as possible – this enables them to have ownership of the garden, and encourages them to take responsibility for it! Ideally, students will have identified a need for, or a desire to develop a garden. This may come about as an investigation of their school environment and environmental practices. Including Parents, Whanau and the Wider Community Successful school gardens often become community gardens, and this can be encouraged by giving all community members a role in the garden development. Too often schools rely on the same few community members to contribute to projects. One way to overcome this is to have students develop a list of things they would like adult help with and then ask all community members to contribute in only one way. An example of such a list may include: • Loaning a trailer • Picking up compost • Donating seeds or seedlings
  • 5. 5 • Collecting mulch • Helping unload compost • Loaning a shovel • Inviting an older community member with gardening expertise • Showing students around their personal garden Students can also set up rosters for community members, so adults take turn in to contribute to the garden as well. Link to the Curriculum It is vital that any garden project links to students’ learning and the curriculum. Gardens are a fabulous context for teaching and learning. A garden provides an authentic context to meet the Vision, Principles, Values and Key Competencies of the New Zealand curriculum (Ministry of Education, 2007). Many learning areas can be integrated into the context of a garden, including: Mathematics - e.g.: measurement when designing; statistics when comparing preferred conditions for plants; calculating volumes of compost, mulch materials; estimating number of plants required; estimating numbers of seeds on plants; collecting data on rainfall, plant growth English – e.g.: writing letters, stories, poems and reports; documenting the process; diary and record keeping; reading and researching; asking questions from experts; using the telephone/ email/ skype etc to connect with other gardeners (including other school gardeners!); sourcing quotes; presenting information about the garden Social Sciences – e.g.: why is gardening important to people; different cultures’ gardening practices; marketing produce; comparing commercial and home gardening; which plants have significance for various cultures; how does gardening contribute to a community Health and Physical Education – e.g.: how does healthy soil and food contribute to people’s health; which edible plants we can grow in our climate and how do these rate for health benefits; minerals and vitamins of various fruit and vegetables; how does establishing a garden contribute to the four areas of hauora: taha tinana (physical well-being); taha hinengaro (mental and emotional well-being; taha whanau (social well-being); taha wairua (spiritual well-being) Technology – e.g.: using appropriate technology (correct tool for the job); designing and creating gardening tools (watering cans, weeding tools, irrigation system, rain water harvesting etc.) and structures (pest traps, climbing frames for beans, weather stations, compost and worm farms etc.) Science – e.g.: biodiversity; soils and soil structures; ecosystems; companion planting (i.e. which plants grow well alongside others and support them by attracting predatory wasps, supply nitrogen etc .); developing and retaining healthy soil; composting; weather monitoring
  • 6. The Arts – e.g.: sculptures and structures; botanical sketching; natural music and sounds; role plays and drama Te reo and tikanga Māori – e.g.: Māori names for plants; planting by the moon; cultivation methods; traditionally grown plants and tools There are also NCEA Education for Sustainability Achievement Standards at Level 2 and 3 now which lend themselves very well to an edible gardening project. Placement of the Garden Out of Sight = Out of Mind! Many school gardens fail because they get forgotten about due to their location. Ideally the students will be involved in deciding where to place the school garden. Criteria they need to consider include: 6 • North facing aspect • All day sun • Not a student ‘playing area’ • Suitable and safe soil • Where everyone can see it everyday • Protected from pests (rabbits; chooks; sheep etc) • Easily accessible by wheelbarrow and / or trailer • Near a water source (outside tap; rain harvesting from a roof) • Distance to existing large trees (especially oaks and walnuts – which can hinder the growth of gardens) Garden Edging If you have the choice, try to use non-treated timber for garden surrounds. Macrocarpa sleepers are ideal for more formal gardens, with child sculptured Oamaru stone, driftwood, bricks and rocks excellent for more creative gardens. Old tyres and treated timber can be used, but be aware there could be some leaching from these into the soil. It is meant to be minimal, but the recommendation is to use these for flowering, rather than edible plants. Using Paper and Cardboard in the Garden Many people ask about using newspaper and cardboard in a garden, with their inks and glues. Some research that suggests that the glues and inks are so minimally damaging for the soil that it is not worth being concerned about. And certainly composting these materials are better than sending them to landfill, or, arguably, to Asia for recycling. However, in saying that, avoid using banana boxes, as they are reputed to be full of harmful sprays. Watering Seedlings especially need regular watering. Designing and making watering cans, rain water harvesting systems or irrigation systems are great ways to enthuse students about getting involved. Mulching also greatly reduces the need for watering. Students can test and trial various mulches, comparing availability, costs and nutritional value for the soil.
  • 7. School Holidays The Christmas school holidays in particular can be an issue for some schools. Some schools worry that everything is harvested during January, while the students are absent. However, as you will see in the ‘What to do When’ section of this booklet, there are many vegetables and fruits that can be harvested during other months of the year. Watering and weeding may be an issue which can be alleviated by mulching and /or irrigation systems, and by developing partnerships with the community, some of whom may be happy to help out over January in return for a share in the harvest. Maintenance Once the garden is up and running and students start to focus on other areas of sustainability (e.g.: reducing energy use, water conservation, sustainable transport, eco-buildings etc.) it is important that the garden is maintained. Some ideas to do this include: • Having two representatives (which change weekly) working in the garden with a garden 7 facilitator at a certain time each week • Classes taking turns for having responsibility for the garden for a certain time • Once a week having an ‘environmental project’ time, when students do jobs including the garden, alongside others such as managing the worm farm, compost, bokashi buckets, paper recycling, other recycling, lost property, monitoring energy use etc. • Having parent and whanau ‘working bees’ during school time, and involving students • Dividing certain areas of the garden for each class • Ensuring that the garden is regularly utilised as a context for learning (see ‘Links to the Curriculum’ above) What to do with the Harvest It is important that students learn what to do with their produce. Ideas include: • Giving it as ‘prizes’ or ‘rewards’ to students to take home • Classes taking turns to share the harvest • Selling fresh produce to the wider community once a week • Eating fresh or cooking the produce at school • Adding value to the produce (making relish, pickles, herb vinegars etc) and selling these at the school fair
  • 8. 2: How to Make a Mulch / No-Dig Garden There are several ways to make a mulch or no-dig garden. The process outlined below is relatively easy and quick, once you have collected your materials. It has the advantage of not disrupting the microlife in the soil, and requires very little weeding or watering. 8 1. Mow or flatten the grass if it is long 2. Create the outline of your garden (use a hose if it is to be curved) 3. Spread a sprinkling of organic matter – vegetable scraps are ideal – to encourage worms 4. Cover with 7 layers of damp newspaper (or you could use cardboard) to prevent weeds growing through. This layer will eventually rot down so you can take advantage of the soil underneath. Don’t use plastic – it doesn’t allow the soil to breathe 5. Place your garden edging over the newspaper (could be non-treated timber, driftwood, rocks or stone) 4. Add at least 10 cm of composted material. Do not use soil, as there will be weed seeds in it 5. Mulch over the top with pea straw / lucerne hay / dry leaves / shredded paper etc 6. Water 7. To plant seedlings / seeds, part the mulch and plant into the composted material. Keep mulch well clear of seeds. 8. Over time, keep on adding mulch, but use a variety 9. It will probably take at least 2 seasons before you can grow root crops in a mulch garden.
  • 9. 3: Incredible Edibles for School Gardens There is a huge range of incredible edibles that grow in our region. These are some of the basic vegetables that grow relatively easily. Apart from tomatoes, they can all be grown outside, without too much special care. The trick is to plant them at the right time so they can be harvested during the school term (see the What to do When section), although many can be grazed on during the year. Plants are listed alphabetically by their common names under three sections; vegetables, herbs, fruit and nut trees and bushes. Brief descriptions are given, care required, known companions and non-companions and uses. 9 VEGETABLES Beetroot (Beta vulgaris) Description: root vegetable with edible leaves Care: plant in Spring to Early Summer for Autumn harvest; likes nitrogen and lime; plant following cabbage, lettuce or tomato; can stand light frosts; tolerates all soils; can grow in semi shaded positions but prefers full sun; can harvest 1/3 of leaves without damaging roots; beetroots are best when 5-9cm in diameter; store undamaged roots in layers between sand or untreated sawdust in boxes in cool places Companions: cabbage; onions Keep away from: beans Uses: can eat raw or cooked; edible roots and leaves (use as for spinach); attractive Broad beans Description: vegetable Care: sow by Anzac Day to eat before Christmas; can sow in Spring to harvest in Term 1; can pinch out tips after flowers appear to encourage pod set – the pinched out tops can be eaten as spinach Companions: cabbages; carrots; cauliflower; celery; cucumber; leeks; marigolds; rosemary; rhubarb; summer savoury Keep away from: beetroot; garlic; gladiolus; onions Uses: edible seeds and tops; Broccoli (Brassica oleracea italica) Description: brassica vegetable Care: plant in Spring or early Term 1; interplant with lettuce (deters white butterfly); nasturtiums (helps deter aphids) Companions: chamomile; celery; dill; onions; peppermint; potatoes; rosemary; sage Keep away from: tomatoes; strawberries Uses: edible ‘flower’

  • 22. 4: What to Do When This is a twelve month cycle specifically for the coastal Otago bioregion, but will be relevant for parts of Southland as well. It is intended as a guide only and local gardeners in your area will be able to assist further. Be aware that climatic patterns contributed to Climate Change result in ‘false seasons’ and can upset the regular cycle of nature. Furthermore, by creating your own microclimate and by placing plants under frost protection, growing seasons can be extended. JANUARY Sow Seeds Root crops: beetroot; radish; turnip Leaf crops: Chinese cabbage; salad greens (lettuce, mizuna etc.); mustard; silver beet; sprouting broccoli Plant Seedlings Root crops: leek Leaf crops: celery; silver beet; winter greens (broccoli, Brussel sprouts, cabbage, curly kale, savoy cabbage) Thin beetroot, carrots, parsnips, radishes, turnips Remove dead / yellow leaves from tomatoes under glass and pinch out young shoots – not necessary for Russian Reds 22 Liquid Manure tomatoes, zucchini Harvest • potatoes and sow green manure crop (blue lupins, mustard, oats), if ground not required, or an put in late crop potatoes if early January • beetroot, brassicas, broad beans, carrots, cucumber, globe artichoke (pick before fully open), herbs, peas and beans, radish, salad vegetables, silver beet spinach, zucchini, currants, gooseberries FEBRUARY Sow Seeds Root crops: onions; turnips (warm sheltered spot) Leaf crops: cabbage; parsley; silver beet; spinach Plant Seedlings Leaf crops: Chinese cabbage; salad greens (landcress, lettuce, mizuna etc.); dwarf beans; mustard; silver beet; spinach, sprouting broccoli

  • 31. 5: Liquid Fertilizers, Manures, Mulches It is recommended that soils are tested regularly to check which trace elements are missing from the soil. To supplement any lacking trace elements, liquid fertilizers, compost, mulches and manures can be added to improve soil fertility. LIQUID FERTILIZERS Animal Manure How to make: most animal manures are suitable; steep a sack full in a drum of water for a month or so How to use: dilute 1:3; refill the drum with water (can steep the same sack full a number of times) Comfrey How to make: steep a sack full in a drum of water for a month or so How to use: dilute 1:2 Seaweed (sea lettuce is excellent for this) How to make: fill drum half full of seaweed; top with water; add a rotten banana to assist the decomposition process; wait until everything is liquid How to use: use 1 cup diluted in a bucket of water Worm Juice How to make: collect liquid from a worm farm How to use: use 1 cup diluted in a bucket of water MANURE Animal Manure The general rule with animal manure is to allow it to break down for a few months before using in the garden. Try to avoid using manure from animals that has been drenched with chemicals. Most manure is suitable, with cow manure particularly useful. Be aware that some manure such as chook manure is high and nitrogen and too much will produce forked carrots and lots of green growth and few flowers (and hence seed) in leguminous plants Green Manure Green manure is plants grown on unused garden beds and then dug into the soil a couple of months before planting the next crop. Leguminous plants are most suitable, such as lupins, beans, clover, alfafa (lucerne), but other plants such as nasturtiums, oats and mustard are also useful. Wood Ash High in potassium and phosphorus, so small quantities are good for root crops. Do not use ash from coal or treated timber (Treated timber should not be burned!) 31
  • 32. MULCHES Pine Needles are an excellent strawberry mulch and around other plants that prefer acidic soil eg: blueberries and rhododendrons Sawdust can be used as a mulch but robs the soil of nitrogen Oak leaves take a long time to break down and are good around shrubs, but avoid as a mulch on vegetable gardens Other leaves make a good mulch on the vegetable garden Pea straw and Lucerne are excellent mulches as they are high in nitrogen, but are expensive if they need to be purchased Shredded Paper can also be used as a mulch, but needs to be well watered or else it blows around in the wind Stones make an attractive mulch, and can act as a heat sink, warming the soil. 32
  • 33. 33 6: Pest Traps and Sprays Pest traps and sprays are considered the ‘last straw’, and are recommended only as a last resort. It is much better to spend time improving the soil so that it is healthy and will therefore grow healthy plants. Interplanting with a variety of plants (including flowers) and rotating crops can also assist in preventing infestations of pests. Some plants such as Queens Anne Lace, parsnips and carrots that have gone to seed and other umbelliforous plants, actually attract useful insects such as predator wasps that eat pests such as aphids. PEST TRAPS Beer Trap How to make: stale beer in a bottle or container How to use: immerse in soil at 45 degrees with opening just over surface, so pests falling in won’t be able to escape Traps: slugs, snails Sugar Traps How to make: mix generous amount of sugar with water and cool How to use: ¼ fill a bottle, place near house or sheds Traps: wasps Orange Traps How to make: cut an orange in half and place cut side down in the garden How to use: in the morning collect pests Traps: slugs White Cabbage Butterfly Traps How to make: soapy water in yellow container How to use: place in garden Traps: white cabbage butterfly MORE ON SLUGS… Slugs can be repelled from gardens by broken eggshells, slugs or sawdust sprinkled around plants.
  • 34. SPRAYS Homemade sprays may be stored in sterilized jars. Chilli / Red Pepper How to make: soak 50g chilli or hot red capsicums in 100ml water for 24 hours; strain and dilute 1½ tsp in 1litre water; use a little soap as a sticking agent Controls: aphids and caterpillars Garlic How to make: soak 4 cloves of garlic in 1litre of cold water for several days and then blend How to use: spray Controls: fungus - club root (water down rows in early summer) and pests – red spider; slugs; snails Lettuce How to make: boil in water and strain How to use: spray on brassica leaves Controls: white cabbage butterfly Alternatives: place lettuce leaf on brassicas such as cauliflower Milk How to make: use 1 part milk to 9 parts water How to use: spray at planting time then every 10 days Controls: viruses on cucumbers; lettuce; tomatoes Pest Tea How to make: grind up large numbers of pests and mix with water How to use: spray Controls: their friends and family Soap How to make: dissolve 2 tablespoons of pure soap in 1 litre of water, or use bath water or water from washing clothes How to use: spray Controls: white cabbage butterfly, caterpillars, aphids Rhubarb How to make: boil 500g of rhubarb leaves in 1 litre water (not in an aluminium pan) for 30 minutes, then cool; dissolve 50g soft soap in 1 litre water and cool; mix the two How to use: spray on brassica seedlings; rainwater increases effectiveness Controls: aphids; club root Alternatives: can use tomatoes stems or stinging nettles instead of rhubarb; can put a rhubarb leaf under a seedling when planting instead of spraying NB: Rhubarb leaves are toxic! 34
  • 35. Water How to use: Hose, with reasonable pressure to knock insects from plants Other: add lime to water and apply around beets and cabbages to reduce scab, club root and cabbage maggot fly; add salt to water to deter cabbage caterpillars; use warm water for soft skinned insects e.g. aphids, caterpillars Controls: aphids, caterpillars Wormwood Tea How to make: 1 tbsp of wormwood leaves in 600ml water and bring to the boil; remove from heat immediately How to use: when cool, dilute 1 part with 4 parts water and immediately pour around vegetables Controls: slugs and snails 35
  • 36. 7. Heritage and Disease Resistant Varieties There is increasing evidence that heritage varieties not only taste better, they are also more disease resistant and have higher nutritional value than commercially available fruits and vegetables. Koanga Gardens in Northland have conducted research in this field. In addition, seed saved from heritage plants will grow true to form as they have not been hybridised. 36 When choosing fruit and nut trees consider: • appropriateness for your soil and microclimate • fruiting times of varieties (early, mid and late) as required – usually a range is best • the purpose for the trees (dessert, cooking, juice, forage) • availability • rootstock Highly Recommended Apple Varieties Liberty; Priscilla; Redfree; Freedom; Akane; Discovery; Novamac; Tydeman’s Red Recommended Apple Varieties Beauty of Bath; Bramley’s Seedling; Cornish Aromatic; Egremont Russet; Florina; Gavin; Hetlina; Jonafree; Lawfam; Laxton’s Epicure; Laxton’s Fortunate; Lundbytorp; Macfree; Merton Russet; Merton Worcester; Nova Easygro; Priam; Prima; Reinette de Thorn; Sir Prize; Splendour; Sunset; Telstar; Tydeman’s Late Orange Recommended Pear Varieties Brockworth Park; Comice; Douglas; Doyenne de Comice; Duchess d’Angouleme; El Dorado; Fan-stil; Kieffers Hybrid; Luscious; Mac; Magness; Maxine; Moonglow; Red Bartlett; Red Beurre d’Anjou; Seckel; Starking Delicious; Starkrimson; Sugar; Sure Crop; Waite; Winter Nelis Recommended Peach Varieties (in order of preference) Red Bird; Sunbeam; Mayflower; Orange Cling; Carmen; Elberta; Greensboro; J.H.Hale; Sneed; Black Boy *all are resistant to brown rot and peach leaf curl Recommended Walnut Varieties Chandler; Eureka; Franquette; Hartley; Howard; Pedro; Tehama; Vina * all fairly tolerant of blight
