Spring is when lots of new vegetable crops that were planted the previous autumn come into their own, and perennial vegetable and fruits are ready for harvesting. Perennials do take up a lot of space but they are reliable early croppers, Rhubarb and Asparagus are two classic examples. If you want leeks for spring harvesting you need to sow those March – April and plant out in July for cropping the following spring. They will spend the winter gathering strength and not appearing to grow much at all, then suddenly they take off like a rocket and come May they will be delicious. Spring Onions do much the same and will liven up your salads and stir fry dishes.
