Cucumbers
Select Your Climate
Grow cucumber vines vertically, on a frame or trellis, to minimise ground space while getting bumper returns.
Likes:
Warm dry conditions, full sun and regular watering.
Dislikes: Cold temperatures, especially cold nights; too much shade and heavy, badly drained soils.
When to plant/sow in zone:
How to start:
Plant directly into the soil if warm enough. If nights are still cold, sow into small individual pots. Plant seeds or seedlings in a sunny spot, into mounds of soil 30–50cm apart to ensure good spacing and drainage.
How to grow:
Water 2–3 times a week during dry weather. Sprinkle a handful of sulphate of potash just after planting, or when seedlings first appear. Bees are needed for pollinating or hand pollinate using a soft, small paintbrush. Avoid watering the leaves to minimise fungal problems.
When to harvest:
Harvest timing depends on the variety but usually when fruits are between 15–20cm long.
Pests and diseases:
Aphids, thrips, mites and pumpkin beetles, downy and powdery mildew and other fungal diseases. Also bacterial diseases and viruses like cucumber mosaic virus.
