These salad mainstays need well-drained soil and a lot of sunshine. Bury tomato transplants up to the bottom set of leaves, and they’ll develop roots along the length of the stem. Keep them watered deeply and regularly, and stake tall varieties early before they start to droop. Foliage that touches the soil is more likely to be plagued by diseases and pests. Pick the tomatoes when the colour is uniform, and the fruits feel firm. Cherry and grape tomatoes are tasty and fun to grow, too.
