Things to do in the school garden -
September and October 2008
Garden Organic - the national charity for organic growing

We would like to welcome you back as you start a new school year. Although the weather has been unpredictable through the summer holidays we hope you all had a great time and enjoyed harvesting and eating some lovely produce from your gardens.

If you are new to gardening we hope that you’ll have lots of fun learning all about organic growing.

There are still plenty of things to be done in the garden at the moment especially continuing to harvest and cook all that lovely produce that you have looked after with such care.

It’s a good idea at this time of year to take a look at your garden and think about what you might like to do next year. Think about what went well, what didn’t do very well and what changes you would like to make or new crops you might like to try. As autumn approaches it is a good time to have a general tidy up, collect seed and think about spring bulbs.

What to Sow, Plant and Harvest

Sow now for winter crops

Spring and summer might be long gone, but there are still crops that you can sow or plant now that will grow over the winter.

Autumn onions

You can grow onions from ‘sets’ planted in autumn. Sets are small underdeveloped onions, which have been heat treated to halt growth. They will get growing again, once planted, and you’ll harvest them next June or July.

  • Prepare the ground by clearing away weeds, and raking smooth.
  • Allow 25 – 30cm between plants and rows.
  • Push sets into the ground until just the tips are showing. You may have to cover with netting to prevent birds from tweaking the onions out of the ground!
  • Hoe along the rows regularly, to prevent weeds taking over.
  • Harvest the onions next summer.

Garlic

Why not try growing some garlic? Just prepare the ground, as you would do for onions, and plant individual garlic cloves, 5 – 10cm deep, with 15cm between rows.
You can try planting garlic cloves that come from a greengrocers, but those varieties are not always the best for growing in our climate. Garlic sold specifically for planting in the UK is often more likely to succeed especially if, like this year, we have a wet, dull winter and summer.

Winter Lettuce

Depending on the variety of seed you choose (see below for suggestions) you can sow now for your own fresh-grown lettuce in January. If you can, cover the growing plants with fleece or clear plastic supported on a frame. This is particularly useful in the worst of our winter weather.

Good choices include:
May King; Winter Density; Rouge d’Hiver

Lettuce leaves

Oriental vegetables

Crops such as mizuna, mustard greens, and salad mixtures, will grow through the winter except in the harshest weather. It’s wonderful to be able to harvest your own fresh green salads all year round. A cloche will help protect young leaves from biting winds, and freezing rain.

All the varieties of winter lettuce and Oriental vegetables mentioned can be found in The Organic Gardening Catalogue.

Harvesting and cooking your vegetables

Tomatoes

You can eat tomatoes fresh as they are when you pick them (after a quick run under the tap). But they can be baked, stuffed, fried, and grilled. They can be used in soups, sauces, casseroles and lots of other dishes. You can also freeze them for use in the winter.

Caring for your tomatoes

As the season progresses continue to care for your tomatoes in the following way:

  • Remove the side shoots, these are the shoots, which appear where the leaf stalk joins the stem.
  • Remove the yellow leaves below the fruit trusses but do not remove too many leaves.
  • Keep the soil moist- alternating dryness with flooding will cause blossom end rot or fruit splitting.

If you have any unripened fruit at the end of the season:

  • Remove the fruited trusses and lay them on a tray.
  • Place the tray in an empty drawer.
  • Place a banana next to the tray, the banana releases a gas, which helps to ripen the fruit.

Green tomatoes
Make some green tomato chutney to enjoy later in the year

If you have a glut of green tomatoes, ask an adult to help you, and try this recipe for green tomato chutney, you could sell the jars to raise funds to buy some seeds for next year. Please note that this recipe takes quite a lot of time to prepare and cook.

Green Tomato Chutney

Makes: 2.7kg

Equipment you will need:

Sterilised jam jars with screw top lids. Jam jars need to be very clean. To sterilise jars, wash in hot soapy water, rinse well and then place in a cool oven - 130°C/250°F/Gas ½ - for 15-20 minutes.

Runner beans

Runner beans are delicious served as an accompaniment to a main meal.
Wash and top and tail them (cut each end off), pull any strings off and then cut diagonally into pieces. Steam or boil them until they are starting to go soft (About 5 minutes). Do not overcook, as they will lose their flavour and all the good nutrients they contain.

You could prepare them and try them raw in a salad or as a snack just on their own. Alternatively, use them with some other raw vegetables that you have harvested such as carrots, celery and radishes to dip in the following:

Curry Dip

1 tbsp mango chutney
6 tbsp mayonnaise
1 tsp curry paste
2 tbsps crème friase
Pinch of ground cumin

How to make it:

  • Cut up any large pieces of mango in the chutney and place in a small bowl.
  • Add all the other ingredients and mix well together.
  • Put in the fridge until required.
  • Dip in your raw vegetables and enjoy.

Beetroot

Beetroot

Beetroot can be harvested when it is small or left until it is larger. Just push a fork under the roots and lift them out of the soil. There are many ways of cooking beetroot including; boiling, roasting or pickling.

To boil them; gently scrub the beetroot under running water, leave the roots on and cut the stalks to about 3cm. Put them in a saucepan of boiling water for 30 - 60 minutes or until tender, this will depend on the size of the beetroot. When cooked, drain and leave to cool. Then scrape off the skin, slice or leave whole, don’t worry if there are any leftovers as beetroot can also be eaten cold.

Plant spring flowering bulbs

Plant a variety of bulbs (see examples below) so that you have colour from January through to May. Tulips can be planted as late as November and will still flower next year.

Tulips – plant in November/December for flowers in April/May
Daffodils – plant in August/September for flowers in March/April
Snowdrops – plant in September/October for flowers in January-March
Crocuses – plant in September/October for flowers in February-April
Anemone – plant in November for flowers in February
Fritillaria – plant in September-November for flowers in April

Save Seeds

It is possible to save seed from lots of different flowers and vegetables at this time of year. You can store the seed over winter and sow it in the spring. Not only will you get lots of plants for free, you'll also get alot of satisfaction growing the seeds you saved. Here are some easy ones to start with.

Pumpkin

  • Harvest the pumpkins when the stalk at the top begins to shrivel, and the skin is hard.
  • Leave it in a warm dry place for about three weeks. This gives the seeds a chance to increase in strength.
  • Remove seeds from the flesh and rinse in a colander to clear away any flesh or stringy bits.
  • Rub the seeds gently under running water until they are quite clean.
  • Allow to dry naturally. A single layer on a tray is ideal. When dry, seeds will break in half rather than bend. Any seeds that are flat and empty are not viable.
  • Store in an airtight container – glass or metal, not plastic – and in a cool dark place. A fridge is ideal but cupboards or wardrobes often make good storage places for seeds.

Flowers

  • Let the seed heads dry on their individual plants.
  • Once they begin to turn brown cut them off and put into paper bags to finish drying.
  • Label the bags clearly with the names of each plant.
  • Hang the open bags in a warm, dry place until all the seeds have been released from the seedpod. You may need to shake the seed heads to get the seeds to fall out.
  • Clean the seeds by gently blowing the outer shell (casings) away.
  • Put each batch of seed in a paper envelope and label clearly. Do not use foil or plastic.
  • Store over winter in an airtight container, in a cool, dry place.
  • Early next spring find out the best time to sow the seed.
  • Before sowing, leave the seeds open to the air for a couple of days to absorb moisture.

Pot up strawberry runners

Now is the time of year when your strawberry plants will be producing runners, it’s easy to grow new plants from their runners. This is what you need to do:

  • Fill some small pots (about 7cm) with potting compost.
  • Select a healthy baby plant on a strawberry runner.
  • Gently push the base of the baby plant into one of the pots.
  • Secure the baby plant in place with some wire, which has been bent to form a hook.
  • Cut off the end of the runner leaving the baby plant still attached to the main strawberry plant.
  • Water the plantlet in and leave to root for a few weeks.
  • When the plantlet has formed roots, cut it from the main plant.
  • After a few more weeks you can plant it out into its final growing position.

Have an autumn tidy

Clear away weeds and unwanted vegetation, and put all this material onto the compost heap. Don’t put weed seeds into a heap though – they’ll survive the composting process.

Roots of difficult perennial weeds can be composted safely and easily.

  • Throw the seed heads away.
  • Put the weed roots into a black plastic sack.
  • Tie up the top.
  • Put the bag in an out-of-the-way corner and leave for several weeks, or even months.
  • When the roots have become smelly sludge, add them to the compost heap. All the nutrients and minerals that they had absorbed from the soil will be returned to the compost, and from there, into your garden!

Some difficult weeds:
Dandelion, Bindweed, Couch Grass, Nettles, Ground Elder.

Don't be too tidy!

All garden creatures need food and shelter over winter. A too tidy garden may look neat but it will be inhospitable for beneficial creatures needing winter habitats.

Here are some ideas:

  • Leave some seed heads on plants. Birds need the food.
  • Leave a pile or two of leaves under hedges, or in corners here and there. Insects and small mammals need the shelter.
  • Make a pile of logs in a corner. Frogs and toads often hibernate in such places. Beetles need plenty of protection in winter weather.
  • Leave some hollow-stemmed plants in the ground, or put the empty stems in with the leaves. Insects will use the tubes for hibernation.
  • Don't cut clumps of bushy plants too low down. Leave plenty of dense growth for insects to snuggle into.
  • Hang some hollow stems in a shrub or tree, out of the way. In very wet weather, hibernating creatures can drown if they are at ground level, and it becomes waterlogged.

Help to attract hedgehogs into your garden

Slugs can be a problem in your garden but hedgehogs eat slugs as part of their diet. Hedgehogs like a garden that has plenty of cover and moist spots where slugs are likely to be found.

  • Create a wild section in your garden by making a log pile with some old logs and leaving some grass to grow long. Hedgehogs also like patches of brambles, old leaves and twigs.
  • Provide some water in a shallow dish for hedgehogs to drink. If you have a pond in your garden make sure that you provide a sloping stony bank so that small mammals can drink safely and escape.
  • Take care when using gardening tools and tidying up as hedgehogs can get injured easily. They like to hide in piles of leaves, long grass and compost heaps.

Activity: Make a simple hedgehog house

  • Get a big, strong cardboard box.
  • Cut two air vents in the sides about 15cm by 5cm and an entrance about 15cm in diameter.
  • Put some shredded newspaper inside with some clean dry grass on top.
  • Tuck the box near a hedge, with the entrance facing south if possible.
  • Cover the top of the box with a piece of plastic sheet (you could use an old large opened up carrier bag). Cover the box with lots of small twigs to make a dome and then cover the twigs with dry grass and leaves.

Have a look at our Indoor Activities and make some other homes for insects.

Making leafmould

As autumn leaves fall they can be collected up and put in a container. Once the container is full it can be left for a year until the leaves have rotted down to form leafmould.

A leafmould container is easy to make.

You will need:

  • Four 4cm x 4cm posts, about 1.25 –1.50 metres long
  • Chicken wire

Knock the four posts into the ground to form a metre square. Chicken wire can then be nailed around the posts to form the container. There is no need to cover a leafmould bin.

Sow green manures

Now is the time to sow green manures on any areas where you have put down mulches to exclude light and kill unwanted weeds/grass. A green manure is a plant that can be used to improve your soil, give better drainage and provide weed control. From September onwards sow winter-hardy green manures, which include; grazing rye, field beans and tares.

Outside tasks

  • On a weedy site: Cut down all the long weeds and cover with a light-excluding covering (any of the following would do; black plastic sheeting, a weed-suppressing membrane, large sheets of cardboard spread out over the soil and weighed down). By keeping light out, weeds won't grow, and when you lift the cover next spring, it will be much easier to dig over.
  • On a cleared site: Cover as above to prevent weeds growing again! You can put a layer of wet leaves down under the covering if you have them. These will break down during the winter months, and add useful organic material to the soil. Or you could grow a green manure (see above).
  • Start building your compost heap. The contents of the heap will rot down and become garden compost – that wonderful fertile material that keeps the soil vibrant with life, and encourages strong healthy plant growth.

Inside tasks

  • Plan the garden for next year's crops.
  • Draw up a crop rotation plan.
  • Choose seeds for next year. Try some resistant vegetable varieties – there are lots to choose from now. The Organic Gardening Catalogue has some wonderful vegetable choices. Don't forget to order seeds of ornamental plants to attract beneficial pest-eating insects.

Make a recipe book

There will be a bumper crop of vegetables available from your garden now so why not get creative and use the produce to make up lots of different recipes.

Try different combinations of herbs and vegetables to decide which you like and which go well together.

Work out the amounts of each vegetable that you need. You can use standard measurements like grams and kilograms or non-standard like a handful or a pinch.

Practice writing instructions, you could hand write them, or use a computer. Look through lots of recipe books and on the Internet for ideas. Don’t forget to include all of the ingredients, utensils, sizes of equipment and the method.

Use a digital camera to photograph all of the stages of preparation and the finished dish. You could also use diagrams as part of you instructions.

Play with words and invent an intriguing name for your dish.

Design the front cover of you book and put all your recipes together.

Send them to us so that we can share them with other schools on our website. Our full contact details are here.

Start to do some planning

  • By sowing and planting at the right time, you can be eating your own, homegrown produce all year round. Use the Cook’s Garden Planner, our website, the internet and your school calendar to plan the year ahead.
  • Work out who’s going to do what and when.
  • Make up a rota for regular jobs.
  • Start to plan ahead; what seeds will you sow in the autumn and spring? Look through the Organic Gardening Catalogue for some inspiration. Perhaps you could think about growing some unusual varieties or vegetables you have not tasted before.
  • Keep records of what and when you sowed.
  • Take photos of your garden regularly to record your year-round progress.
  • Record crop yields and find graphic ways to report them.

Make some winter homes for insects

As the weather starts to turn colder insects and creatures in your garden will be looking for places to shelter. You can use recycled materials to build suitable homes for them.

Take a look at The Organic Gardening catalogue or do a search on the Internet to find examples of wildlife homes that have been manufactured by different companies. Which ones do you think will work best?

Then follow our instructions or design and make your own winter homes for your garden friends.

Lacewing Hotels

Lacewings can eat up to 10.000 aphids in their life. Just what the organic gardener needs!

Look at the Garden Organic factsheet on lacewings to find out more about this fascinating insect and instructions on 'how to construct a lacewing hotel'

Ladybird House

Most ladybirds and their young (larvae) are carnivorous, feeding on and helping to control large numbers of insect pests, particularly greenfly.

  • Use an old plastic food container, like a margarine tub or ice cream tub.
  • Put holes in the lid with a knitting needle or something similar. (Take care when using sharp object and get an adult to help if you need it.)
  • Stuff the inside of the box with straw and put the lid on.
  • Place the tub on its side, under a bush or large plant to keep it dry over the winter.

Ladybirds and other predators will crawl in and be protected from the cold, rain and wind of the winter months ready to help you out in the garden come the springtime.

Look at the Garden Organic factsheet on Ladybirds to find out more about this much-respected insect.

Identification charts

Make your own identification charts for insects, vegetables, flowers, fruits and trees. Use photographs, pictures from magazines, or your own artistic skills to create the chart. Research each subject and write some fascinating facts that will go with the pictures. When you go outside again you can take the charts to help you identify things in your garden and the countryside around you.
