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.

Culinary hints - cooking and eating Cucumber

Pick frequently before the fruit become too big.
Use raw in salads, peeled if preferred.

I have read good and bad things about growing tomatoes and cucumbers together. Mine are doing really well together. Why do they say it's bad

Where do I buy apple cucumber seedlings in the southern suburbs of Melbourne please?

Apple cucumbers will germinate very quickly at this time of the year and will take off easily. Cucurbits resent root disturbance as well. A packet of seeds would be half the price and would give you 2 or 3 times as many plants. You could save some of the seeds for next year. trust this helps.

Do you need to manually fertilise the females flowers with male pollen like we do with pumpkin ?

How can you tell when they are ready to be picked

Anything above 10cm is good. Younger ones have a nice nutty flavour. leave them too long and they become a bit watery and sour.
