The edible cucumber grows as a trailing and climbing vine. It has green leaves and small wiry stems – known as tendrils – that curl around support structures, allowing the plant to climb. This plant has yellow male and female flowers, with the female flowers having a tiny unfertilised cucumber directly behind the flower.
We are used to seeing cucumbers that are long and green, but cucumbers also come in other shapes and colours. There are round ball ones, some quite small and others the size of tennis balls; there are short and stubby cucumbers; and ones up to 30cm long! Skin colour can be light green or dark green, but also white, cream, yellow and striped.
Cucumber has traditionally been grown for the long fruit, which is used in salads and in sandwiches. However, many people don't realise that the pickled gherkins you see are actually baby cucumbers that have been preserved. There are also various recipes where cucumbers are cooked, rather than eaten raw.
Cucumber is grown from seed. These can be sown directly where you want the plants to grow, or into punnets or pots to give yourself a head start.
Sowing time depends largely on where you are. In temperate and arid areas, sow in the frost-free warmer months. In the tropics you can sow virtually year-round.
When your cucumber first grows, it may need a little help to cling to the climbing support. Use some soft tie or string for this job. Once the plants have reached about 10cm they should produce their own tendrils to let them cling onto the frame.
If you find that you get flowers without fruit, it may be that the female flowers are not being pollinated. You can help with this by growing lots of bee-attracting plants in your garden. You can also manually pollinate by taking off a fresh male flower and rubbing it onto a freshly opened female flower. Remember, females are the ones with the tiny fruit behind the flower.
Sometimes cucumbers get spots of a white powdery substance on the foliage. This is called powdery mildew, and can be controlled with a garden fungicide. You can also reduce the incidence of this by watering the ground and not the foliage, watering early in the day and also ensuring you have well-spaced plants growing in a sunny and airy location.
Occasionally, you might also find ants on your cucumber plants. Generally speaking, ants won’t harm your cucumber plants and don’t need to be controlled. The ants are feeding on honeydew left behind by aphids and other sap-sucking insects. If you control the aphids, that will get rid of the ants.
After applying fertiliser, delay harvesting for a few days and rinse well before eating. If using products to deal with pests, diseases or weeds, always read the label, follow the instructions carefully and wear suitable protective equipment. Store all garden chemicals out of the reach of children and pets.
