(Best months for growing Cucumber in New Zealand - cool/mountain regions)

P = Sow seed

October: After risk of frost

  • 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
  • Avoid growing close to: Potato, Tomatoes
  • Cucumbers on plant ( - Rasbak - CC BY-SA 3.0)
  • 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.

First time planting and i put tomato next to it. What can i expect?

I have just read on several websites that tomatoes and cucumbers are compatible. Don't grow near potatoes. I recently had tomatoes in one bed and cues in the next bed, beds 1.2m apart, beds 4.8m L x 2.5m W. Cues need space to spread out so don't plant close to other crops. Also consider if the tall plants will shade out the lower growing crop.

In my experience, the tomatoes grow well but the cucumbers struggle .
19 Dec 19, Anon (New Zealand - temperate climate)
Tomatoes have a deep and wide root zone and would probably pinch most of the water and nutrients in the soil. Tomatoes need a lot of water and fert, cues far less. That is why I never recommend planting things too close to each other, give them the required area they need.

Why do my cucumber plants have some yellow leaves. I have given them general Fertilizer and also Worm team. Do I need to do anything more as I may have planted them a bit early. Also how do I tell the difference between a female and male flower.

If you put a lot of N on, the leaves would be dark green. If too little N then the leaves would be light green yellow. If too much N then it would burn and kill the plant. Worm tea is only a soil enhancer, gets the bugs etc going. It could be a deficiency of some trace elements in the soil.

If your soil is sandy and you do a lot of watering, then you would leach out the nutrients. Have to apply more fert.

Depends how old the plants are, if 8-10+ weeks then leaves yellowing off would only be natural.

The yellow leaves might be due to too much fertilizer. Try just using one type. They should grow if you are giving them enough water and protecting from very cold nights. The female flowers have a tiny, cucumber shape just behind the flower.

Sometimes the cucumber plant only has male flowers. Is this normal? and sometimes the female flower forms a cucumber and shrinks and falls off.Why is this?

My cukes were planted about a foot ( 30 cm ) away from my tomatoe plants this year.and my crop from both was unreal. The tomato plants acted as a trellis for the cukes. I could not keep up with the supply....
