  • S = Plant undercover in seed trays
  • T = Plant out (transplant) seedlings
  • P = Sow seed
  • Sow in garden. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 61°F and 95°F. (Show °C/cm)
  • Space plants: 16 - 24 inches apart
  • Harvest in 8-10 weeks. Cut fruit off with scissors or sharp knife.
  • Compatible with (can grow beside): Nasturtiums, Beans, Celery, Lettuce, Sweet Corn, Cabbages, Sunflowers, Coriander, Fennel, Dill, Sunflowers

  • Young plant
  • Female flower with baby fruit
  • Male flower

A trailing plant which will grow tendrils as it gets bigger. Cucumbers can be started in small peat pots then transplanted when weather is suitable. 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 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. Bash them with a rolling pin before slicing and marinade with a rice vinegar/fish sauce/sugar mix and they will absorb the flavours of the dressing.

CUCAMELON: This is the fourth season growing the Cucamelon in Adelaide and getting a better result each year, but the vine and leaves turn brown and die off rather early. Any suggestions please.

Hi, I planted 2 Lebanese cucumbers last year and again this year. Both were/are healthy plants. Issue is..there are many female flowers (hundreds) and they just wither and die. Not a single male flower both seasons. Should I be planting a different variety of cucumber nearby to help with male flowers and pollination? Help!

Cucumbers. I always grow Lebanese Cuces, supported by the chicken wire fence of my garden. This year the vines look great and there are lots of bees feeding on the flowers, but I am only getting about one Cuce per day. Feeding liquid manure, mixed with Dynamic Lifter. Any ideas why the crop is so small? Cheers Pete.

Switch to fertilisers labelled "flowers and fruit", fertilisers with a lower nitrogen content. Animal manures have a high Nitrogen content that is good for basic plant growth. For example, Dynamic Lifter which is pelletised cow manure has an NPK (Nitrogen, Phosphorus, Potassium) ratio of 3.5 - 1 - 1.6 which is good for initial growth, but switch to another fertiliser when the plants are growing strongly.

If you compare a general fertiliser with some of these specialty fertilisers there is very little difference between them. I use Nitrophoska which is 15 - 6 - 12. It is used by commercial vegetable growers. Manures do not have high N content compared to commercial fertilisers. You just do not put raw manures on heavily, especially chook. You judge how much fert you put on by how high the npk is. A handful of fertiliser per sq meter is sufficient to grow a lot of crops. Applied a week or two before planting seed/seedlings and turned in.

A good fertilising at planting is all they need. A light fertilise maybe when they start flowering. Can't help with the reduced crop. I picked over 120 cues off 5 plants November.

Morning I can’t post a pic by looks of it but I’m a learner gardener and have cucumber growing but the leaves look Like they have some sort of fungus on them so not sure on how to fix it

Google fungus on cucumbers. It comes up with powdery mildew - see if the photos look the same as your cucumbers.

I have two types of cucumber I wish to plant along a long fence. Can I plant them next to each other or will I end up with a hybrid between the two?
