A trailing plant which will grow tendrils as it gets bigger. Cucumbers can be started in small peat pots then transplanted when weather is suitable. 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 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. Bash them with a rolling pin before slicing and marinade with a rice vinegar/fish sauce/sugar mix and they will absorb the flavours of the dressing.

I think I'm going to lose my cucumbers to mold. Is it too late to plant new?

I'd try starting a packet of fresh cucumber seed in a domed container (to keep in moisture to speed germination) and soak the seeds the night before... Then you should be able to choose the biggest seedlings to up pot for a week or so and get them hardened off. You could still plant out the other small seedlings as well and with that many seedlings you may get the amount of cukes you were short on with the loss of your damaged plants. We lost plants due to deer eating them and had to do this... The heat of the summer was a challenge with tender transplants but we still had cucumbers in the end. Not as big, but smaller cukes are good for salads and pickles. I'd throw a packet in some water and get them in a container with drain holes and some good soil... get them going... they are pretty fast. Hope this helps! Best of luck!

I planted my cucumber plants 3-4inch apart in about a15 inch space. At the end of a elevated garden. I took hog or pig wire made a arch off the end of the bed. Trained the plants to climb up and dow the arch. The wire was so spaced I could put the cucumber in the holes in the wire to support the vegetable. It loved it

My garden area isn't super big - how far away/close can my cucumber and tomato plants be?

Check the calendar planting guide on the cucumber page.

I plan to plant them in a spot with a bag of composted chicken manure in Zone 8b. Any suggestions? Last year my cuke plants were glorious and were started from a packet of seeds. Unfortunately I did not get one cuke. Lots of flowers but I think they turned out to be all males.

Mix in well composted manure with some good friable soil - about 1 part manure to 3 parts soil. Too much manure and the soil will have too much nitrogen. The female flowers have little cucumbers behind the flower. You need bees to pollinate the flowers. Check between 7 and 11am to see if bees are active. You can hand pollinate, read how to do it.
