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.

Why are my cucumber plants not making a cucumber, only flowers?

Cucumbers often produce male flowers early in the season before they start to produce female (cucumber) flowers. The male flowers have a longer stem and do not have the unformed cucumber at the base of the flower. I'd say, give them a bit more time.

I am in Zone 7b. I tried some Asian cucumbers - they turned out pretty well this year - you should consider giving them a try. They got up to 1-2 feet. Check them out here -> earthlychow. com/asian-cucumber-tien-chin-long

I grow an open pollinated variety of cucumbers (straight Eight) Two years ago I picked 83 cucumbers from two plants. This past season I only picked 18 cucumbers from two plants, 1. I had problems with cucumber beetles. Any suggestions on how to rid or control then? 2. Also, I believe that the were far less bees around to pollinate. No bees, no pollination. No pollination , no cucumbers. What is the best flower / herb that I can plant to attract pollinators to my cucumbers. Thanks

The only issue is when planting them too close together. They will compete heavily for nutrients and moisture. they are both very heavy feeders .. as a result quality/ flavor could suffer.

Just wanted to find out why you should avoid planting cucumbers next to tomatoes.. I did just that before reading this. My plants are small so is it possible to move them? I just dont want to disturb their new area. Any feedback on this? Thanks so much. your website it terrific!

My cukes were planted about a foot ( 30 cm ) away from my tomatoe plants this year.and my crop from both was unreal. The tomato plants acted as a trellis for the cukes. I could not keep up with the supply....
