Fresh Cucumbers from Small Spaces

You do not need a vegetable plot to grow cucumbers. With the right variety and a large enough container, a sunny balcony can produce a steady supply.

Pick a compact variety

Choose bush or dwarf cucumbers for containers. These stay manageable and do not need the tall supports that vining types require. Some patio varieties are bred specifically for pots.

Use a large pot

Cucumbers have extensive roots. Use a container of at least 30 litres with drainage holes. A light, free-draining potting mix with compost works well. Avoid reusing tired soil from previous years.

Sun and shelter

Give plants at least six hours of sun and protect them from strong wind. A south-facing wall is ideal. In hot climates, afternoon shade can prevent stress.

Water and feed

Containers dry out quickly. Check moisture daily in summer and water deeply when the top few centimetres are dry. Feed every one to two weeks with a balanced liquid fertiliser once flowering starts.

Support and harvest

Even bush varieties benefit from a small trellis or cage to keep fruit off the ground. Harvest young and often. Remove any damaged or yellowing leaves to keep airflow around the plant.

Pollination

Outdoor cucumbers rely on insects. If pollination is poor, hand-pollinate by transferring pollen from male to female flowers with a small brush. Greenhouse varieties often need no pollination.
