Cucumbers can be started in small peat pots then transplanted when weather is suitable. A trailing plant which will grow tendrils as it gets bigger. Lebanese cucumbers are best picked about 10 -12 cm (4 - 5 in) and eaten whole. Gherkins are usually picked 5 or 6 cm (2 - 3 in) long and pickled. They have a prickly skin. Apple cucumbers are round with a pale, almost white, smooth skin.

Grow in full sun. Grow up a trellis or framework to save space and keep the fruit clean. Needs ties to support it at first. Water regularly and fertilise to encourage growth.

Culinary hints - cooking and eating Cucumber

Pick frequently before the fruit become too big.
Use raw in salads, peeled if preferred.

Can I plant tomatoes and cucumbers together? This seasons tomato bed has a trellis and our cucumbers have been terrific since growing them on a trellis.

It is a bit like going for a swim in winter compared to summer. It is a spring crop - not winter. It says plant from August - that is only 4 weeks away. There is a reason why you plant at a certain time - different plants need different temperatures to grow - to achieve the best results.

I am getting lots of flowers on my plant and they are turning into fruit, but die at about 2cm, why? How do I get more fruit, I only got 1 cucumber that grew to 10cm

This may be a bit late for this year but my best suggestion is that after one or two fruit (cucumbers) on each runner have set, pinch off the end of the runner. This means the plant puts its resources into the fruit instead of growing a longer runner. Cheers Arismac

Try growing on a trellis. An inverted V or even a vertical one. I'm trying a vertical one at the moment. Pumpkins and watermelons take up so much room. Best to decide what you are going to plant and where before you start planting. Give each the required area to produce a good crop.
