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.

New to veggie gardening. Is it too late to plant cucumber seeds? I can see from the calender this the last month. Also with a raised veggie garden will mushroom compost be the best?

This website is a guide, it is not spot on about everything. It tells you to apply local information. Gardening is a lot about trying different things but the times to plant are what they consider the best time to achieve the best results. If it says to plant Nov to Feb then you could probably plant Oct to Mar. I find mushroom compost to be very expensive for what is in it. Any kind of compost will do, manures, grass/leaf compost, seaweed, worm poo/tea, any organic matter that has broken down. An easy way is to put grass clipping/ straw etc as a mulch (only about 50mm thick) around your plants, as the plants grow the mulch will be wet and start to break down, by the time the crop is picked it is half way to compost, then dig it into the soil.

I usually grow very good cucumbers and usually Lebanese variety. This year my plant is covered in cucmbers but instead of starting off green I have an abundance of tiny yellow cucumbers on my vine. What causes this?

Phone an agricultural depart, nursery, or some agri supply company and ask if they have an agronomist. Could be some trace element deficiency.

First time planting and i put tomato next to it. What can i expect?

I have just read on several websites that tomatoes and cucumbers are compatible. Don't grow near potatoes. I recently had tomatoes in one bed and cues in the next bed, beds 1.2m apart, beds 4.8m L x 2.5m W. Cues need space to spread out so don't plant close to other crops. Also consider if the tall plants will shade out the lower growing crop.

In my experience, the tomatoes grow well but the cucumbers struggle .
19 Dec 19, Anon (New Zealand - temperate climate)
Tomatoes have a deep and wide root zone and would probably pinch most of the water and nutrients in the soil. Tomatoes need a lot of water and fert, cues far less. That is why I never recommend planting things too close to each other, give them the required area they need.
