Jekka's top tip: Some varieties (for example Chervil, Coriander, Parsley and Lettuce), can also be sown for a second time in late summer or early autumn for a later crop. Many gardeners actually find sowing later works best, particularly for a winter or early spring crop rather in the height of summer.
