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.

Hi, I am planning to move to Mount Victoria up in the Blue Mountains and was wondering if cucumber can grow in the cooler climate? Thanks!

You should be able to grow cucumbers successfully at Mt Victoria even with a longer winter as you get hot summers. Plant the seeds indoors in September in egg carton cells ready for transplanting into the garden in October. Plant the carton cell as well, it will rot. You can plant seed up until mid December. Choose a warm spot with good air circulation to reduce mildew problems. Growing them on a trellis is also beneficial.

Had such wonderful success with cucumbers in the summer of Jan - March. Will cucumbers grow in any other months in Endeavour Hills, Melbourne, Victoria? Question 2. I do not use any chemicals so have you a good idea of how to keep those moths away from Kale? If I put bird mesh over, the moths poke their noses tongues through.

To control cabbage moths and butterflies you could use Yates 'Natures Way' this is a safe organic spray and is harmless to everything except caterpillars. I have also heard of mixing bicarb soda and flour 50/50 and using as a dust. I haven't tried it but others say it works. It wouldn't cost you much to give it a try.

Cucumbers like frost free conditions so can be planted after the last frost. Try planting them in September in egg carton cells or toilet paper cylinders and keep them inside on a sunny windowsill. They can then be planted out in late October when the soil has warmed up. Most summer crops can be planted in late October in southern Victoria. You often hear people say 'after the grand final' or around Melbourne Cup as this is about when the soil normally reaches 17 degrees.

What time of the year do plant cucumbers in Adelaide we have many days over 33 degrees
06 Mar 17, John (Australia - temperate climate)
Cucumbers can be planted in Adelaide in the spring and summer. they like a good trellis to climb on and the tips can be pinched to encourage bushier growth. To reduce the chance of sunborn on those scorching days plant them along an east facing fence if you can. This will shelter them during the hottest part of the day. The other alternative is to plant a block of sweet corn and when the corn has taken off plant the cucumbers at their bases. This will give you free shade, free stakes and double crop! The stalks could also be used to support peas in the autumn and winter. Trust this helps.

How to tell when apple cucumbers are ready to pick
06 Feb 17, John (Australia - temperate climate)
Most varieties of apple cucumber are ripe when the greenish tinge has gone and they are a clear white. When they are overripe they go yellowish and are often bitter. This would apply to most apple cucumbers but there are some more recent varieties available that are green when they are ripe and some that are a golden, almost brown colour. Trust this helps.
