All that tomatoes require is a warm spot out of the wind. Many people grow them in containers on their patio, or in a bed in a greenhouse. Each plant requires a small space, as you are looking for a single stem upwards unless you’ve chosen a bush or tumbling variety. For the longest summer harvest, grow your tomatoes in the greenhouse, though outdoor ripening will carry its own flavour.
Ensure that your tomatoes are well fed and watered, and train any trailing varieties against a support cane. One option is to plant your tomatoes into growing bags. It’s important to do this at the right time – not straight away, but when the first truss of flowers has grown.
Knead the growing bag and form it into a mounded shape. Puncture drainage holes into the bottom, and cut out planting squares at the top.
Make holes for the roots balls to be planted deep enough to be lightly covered. Then water and firm in. Use growing bag frames, and don’t forget the support cane for each plant, secured to the frame.
If you are planting out your tomato seed in late February, fill a small 7 to 8 cm pot with compost. Firm this lightly down and water. Scatter a thin sowing of seeds, then leave on a windowsill to germinate. If you are growing several varieties of tomatoes, don’t forget to label each pot!
Seedlings will grow up within 14 days, and in two months it will be time to pot in. This should be done gently and carefully, potting one plant into a 7 to 8 cm pot. It is time to plant on again when you spot the roots extending out from the drainage holes. When you observe this, pot each plant on into a larger 12 to 13 cm pot.
