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.

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.

Hi, I have apple cucumbers growing vigorously and with heaps of male flowers but no female flowers. What can I do please
04 Feb 17, John (Australia - temperate climate)
I don't know of anything that will induce cucumbers, pumpkins, squash, etc to produce female flowers. Male flowers are always produced first but it is very frustrating. Female flowers generally appear as the season becomes consistently warmer. Trust this helps.

You can encourage pumpkins to put out more female flowers by snipping the growing end off after about 1.5 to 2m of vine. This made side shoots, which tend to make more females.

Could you please tell me when to plant Suyo Long Cucumber in Brisbane, should i put in jiffy pots to start or straight in ground where they are to grow.
05 Feb 17, John (Australia - temperate climate)
Direct sowing is always the best but Jiffy pots are OK. (They do not like root disturbance that can occur with transplanting from trays). They don't like frost but that shouldn't be a problem in Brisbane and as they are very mildew susceptible they don't like overhead watering. Good air circulation and ground watering are good ways to reduce mildew problems. Trust this helps.
