If you've got room in your vegetable plot, pumpkins and squashes are very rewarding vegetables to grow. The important thing to bear in mind is that they need warm weather (including nights) to get off to a flying start, so you can either sow them in pots and keep them under cover until it warms up, or sow seeds in a bed covered with a fleece that’s left in place until the warm weather arrives. They will need lots of nutrients and plenty of water to produce their crop, so plant them in soil that has been enriched with well-rotted manure or compost and mulch the plants to help retain moisture. Bush varieties can be grown in large containers, but trailing varieties need plenty of space to sprawl and climb. You can either pinch out the growing tips after a fruit has formed, for large specimens, or let them get on with it for more smaller fruit. Regular liquid feed will stop them running out of steam.
