Money-saving veg crops to grow

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.

Swiss chard

This trendy veg is a great bet as you can rarely buy it in the shops. cook the leaves like spinach and eat the braised stalks with cheese sauce. Seeds are cheap and it’s a foolproof crop that’s highly productive in a small space. Sow from spring until late summer. Summer-sown plants will give a second crop the following spring.

Celeriac

This delicious, versatile, bulbous-rooted veg tastes a lot like celery. Try it grated raw in salads, cubed and roasted, mashed or added to casseroles. You’ll find there are lots of seeds in the packet and that it’s not difficult to grow, although it needs rich soil and regular watering. These tasty roots can cost around £1 each in the shops.

Mixed salad leaves

Never be without the makings of a thrifty side salad, sandwich or garnish. Sow seeds evenly all over the surface of a trough or tub of compost in a cool, semi-shady place. This crop is also good on windowsills indoors from autumn to spring. Snip leaves like mustard and cress when they are big enough.

Tuscan black kale

Although fashionable, this is not a vegetable you often see sold in the shops. Use tender young leaves in salads and cook the full-sized leaves by steaming or in a stir-fry. Make several sowings each season for a constant supply in summer, autumn and winter. Seeds are cheap and it’s easy to grow.

Save your own seed

Collect traditional non-F1 hybrid varieties, but only when they’re grown at least 250 yards away from other varieties of the same veg which might cross-pollinate them. Don’t save F1 hybrids: the resulting plants are too varied.

Save part-used packets of seed

Roll down the tops of the packets each time you use some, and store any left over at the end of the season. Keep packets in a glass jar with a sachet of silica gel in the salad drawer at the bottom of the fridge. Don’t bother saving parsnip seed – they need to be bought fresh each season.

Sow seeds thinly and evenly

Sow sparingly to make a packet of seeds go further. It also saves a lot of thinning out for direct-sown seeds, and means easier pricking-out when you sow in pots. Mix small seeds such as carrots with sand if it helps to sprinkle them thinly.

Share seeds with friends or neighbours

Give away or swap surplus veg seedlings among yourselves. This is ideal when each of you wants just a few plants of several varieties. Suggest the gardening club sets up a table so members can sell their spare plants. This helps to cover the cost of seed.
