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.

Is it to late to plant cucumbers and how get rid of rats low cost way no poison thanks
22 Feb 19, Michael (Australia - temperate climate)
You have left it very late to plant. You may or may not grow a crop - you can try. No idea on the rat problem. Look on the internet - but gee Ratsack works - you are going to kill them anyhow, does it really matter how.

Borage is a great plant for attracting bees ..they absolutely love it. It’s a very hardy plant with lovely blue flowers but it can reseed and spread around the garden

I grew borage last year in the winter - grew tall 1.2m high and bushy - fell over everywhere. Had to stake and rope it. A bit turned off by that. Bees love it. I now grow a perennial basil for bees. Will have my own bee hive in a few months.

I have Tomatoes and Apple Cucumbers growing in the same veggie garden. Cucumbers are about 50 or 60 cm behind the tomatoes. I have them on a vine but the leaves and flowers or fruit keep dying slowly from the bottom of stem gradually going up. The leaves at the top half are still green and flowering have found little bugs maybe aphids or little spiders on the back of the green leaves. Does anyone know what they are or how to get rid of them. Tomatoes are growing and fruiting fine. Are they the problem?

If you read the notes here on cucumbers it says don't grow close to tomatoes. Could be cucumber fly problem if leaves are being eaten.

I have just grown crystal apple cuies - a lot better taste than the green ones I believe. Available Boondie seeds.

Try any variety. Prefer all day sun.

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!
