Growing vegetables from seed can make a limited budget go a long way. Some crops, such as maincrop potatoes and onions are fairly cheap to buy in shops, so growing your own might not save you a lot of money. But runner bean, cherry tomato and courgette plants are extremely productive, so you'll harvest generous amounts from a smallish space. Salad leaf seeds are another good investment, as they grow fast and give useful crops from the tiniest patch, or a container.
Early and late crops are another good bet, as they crop when fresh veg and salads are at their priciest in the shops. 'Exotic' or unsusual crops, such as mangetout peas, celeriac, golden courgettes or yellow tomatoes are expensive to buy, but easy to grow from seed. Although crops such as peppers, chillies and aubergines do best in a greenhouse, they'll grow well in tubs on a sunny, sheltered patio.
