Growing Tomatoes in Containers

Crop

Tomatoes are among the most rewarding container crops for a sunny British patio or greenhouse. A single healthy plant can provide weeks of fruit, but it needs root room, warmth, support and regular watering. Choose compact bush varieties for pots, or cordon varieties where you can provide tall secure supports.

How to do it

Grow young plants on in a bright, frost-free place, then move them outside only after frost risk has passed. Plant one tomato in a large container of peat-free multipurpose compost, or use a grow bag at its stated spacing. Set a cane, frame or greenhouse string in place immediately. Keep compost evenly moist, watering deeply at the base and checking daily in warm weather. Feed once plants are established and fruiting, following the fertiliser label. Tie cordon stems loosely as they climb and remove side shoots where appropriate for the variety. Harvest fruits when fully coloured and slightly soft, before cold autumn nights slow ripening.

Best plants

Bush tomatoes are ideal for patio pots, hanging baskets and compact containers because they need less training. Cordon tomatoes suit greenhouses and sheltered sunny walls where a tall support is available. Cherry tomatoes are often dependable and productive in the British summer. Pair tomatoes with basil in separate or spacious companion pots, keeping both well watered and in warmth.

Tips

Irregular watering can lead to split fruit and other avoidable problems, so build a daily routine. Use the largest pot you can manage and never crowd several plants into one small container. Ventilate a greenhouse on warm days. Remove lower leaves only when needed for airflow, and protect outdoor plants from cold, exposed sites.
