Growing cucumbers both outside and in a greenhouse or polytunnel requires a little effort for a very large crop
Cucumbers come in all sorts of shapes and sizes. Modern hybrid types produce all female flowers and the seed is extremely expensive but a couple of plants will provide enough produce to feed a family as well as many friends and neighbours. There are many traditional varieties which can be grown both inside under glass and outside. However, to get good crops the plants need to be very well fed and watered and allowed to grow up canes and along wires to ensue the best crops.
I like to sow seed early in April in my propagator set at 24 degrees centigrade, although a sunny windowsill is fine – one seed of hybrid types and two or three of other types on their edge into seed compost in 75mm or 100mm pots. As the seedlings emerge select the strongest to grow on, removing the rest. Once you have four true leaves the seedlings can be removed from the propagator and allowed to grow on on a shelf.
Once the plants are about 20cms high they should be ready to plant into their permanent positions. If growing under indoor varieties they should be planted one metre apart and tied to canes that are the height of eth greenhouse. I then run wires at 20cm intervals across the canes so that I can tie in the side shoots of the plants as they grow.
Dekah is an off-list variety of prickly-skinned cucumber I got initially from the Heritage Seed Library. The fruit are early, have great resistance to mildew and produce delicious fruit over a long growing season. this year I need to save more seed so have left a few fruit to grow to full maturity. When ripe they will be over 30cms long!
