Far too many gardeners regard their season as starting in the spring and ending in the autumn. They will tell you that they put their garden to bed for the winter, and mainly occupy themselves with other activities.
This is a pity, as with a little planning and effort it is possible to provide a range of supplies for the kitchen. Salad crops are particularly useful as the ones available in the shops are likely to be even more heavily treated with chemicals during the winter months. Those produced in this country, for example, will have been grown in glass-houses or poly-tunnels where they are likely to have been sprayed several times with fungicides.
Indoors
Obviously without a heated greenhouse and considerable expense what we can do in our gardens is going to be limited, but we can make a worthwhile attempt to provide something for the table free from chemical contamination.
Take lettuces first of all. You may not have a heated greenhouse but you do have a house with warm rooms. Last winter l managed to maintain a constant supply of lettuces, albeit only a few leaves every day for lunch-time sandwiches, by growing them in pots on window-sills.
The lettuces l grew were called Kelly's and they are specially for glass-house cultivation. They were grown in 450g size yogurt pots, about 20 of them, and kept in trays on light window-sills. They are not lettuces that heart UP, but leaves can be picked from the bottom of the plants and new leaves are produced at the top until they run to seed in the spring, Their fresh green leaves look a treat on the window-sill on a sunny winter's day.
Another salad crop is chicory. These plants grew in the garden during the summer and autumn until cut back by the frost. The roots can then be dug up and kept in pots or boxes in a cool frost free place. They must be kept without light and will remain dormant until brought into a warmer environment. With light still excluded, the plants will soon produce the pale chicoons that can be used in salads
And outdoors
In the garden itself an exceedingly hardy plant can be sown in late summer for winter use. This is land cress, very withstand harsh winter conditions and continue growing during mild spells until it runs to seed in the spring. Its tangy leaves can be picked for salads throughout the winter.
Corn salad or lamb's lettuce is another winter crop that can be grown in the same way as land cress. Both these plants can be grown in the open, but they would be even more productive if protected by cloches or a cold frame.
Another green vegetable that can help out with salads is leaf beet or perpetual spinach. Although this is regarded as a vegetable for cooking, it is extremely hardy and will go on producing young leaves suitable for salads until the colder weather starts. As soon as the milder weather arrives in early spring, it starts again to produce a crop of young green leaves. Even in mid-winter, if you cover some of the plants with cloches, there will be some leaves for picking.
Root crops for salads can be sown in the summer and either left in the ground to be dug as required, or dug up and stored for winter use. Winter radish is such a crop. I leave mine in the ground and give them a covering of old grass cuttings or straw to keep out the frost and dig up the roots which are up to 6 inches long ; a tasty addition to the winter salad. Carrots and beetroot can be left in a similar way and, grated raw, add color to salads
A crop seldom grown but ideal for winter use is the Jerusalem artichoke. A neighbor gave me some tubers to sow over 20 years ago, and they have been providing winter food and tubers for planting ever since.
The tubers are planted around March and produce 8 foot high plants similar to sunflowers but without the flowers. The foliage is cut down and composted in the autumn and the tubers can be dug up as required. They are really good chopped up raw in salads as well as being useful for soups; they are also delicious roasted with the potatoes in the oven.
Jerusalem artichokes can be somewhat knobbly and difficult to prepare, but over the years I have selected the smoothest tubers for seed and now my crop consists in the main of good smooth roots. Some people swear by Jerusalem artichokes and some people swear at them, but l regard them as a first-class reliable winter vegetable.
Another good standby for winter are the squashes. I usually grow small pumpkins which store well in a cool place and are tasty chopped raw in salads. They are also useful for making soup.
With the growing prospect of global warming, we are likely to see changes in our climate. As well as an expected reduction in annual rainfall in our part of the country, we are also likely to find milder conditions during the winters. Despite the threat of more serious storms, this could make it easier to grow winter crops. Even without these changes, though, there is still much that can be done now.
