A Basic Guide To Successional Sowing And Cropping

Successional sowing or planting of vegetables on a particular piece of ground will ensure a constant supply for the kitchen. Such successional cropping can be achieved either by sowing or planting the follow-on crops.

A Succession of Greens

It is not possible to obtain regular supplies of greenstuff (brassicas) from a single sowing. Different varieties mature at different times and once ready they will not remain in good condition indefinitely.

A large seed bed is not necessary and one of approximately 2m x 1.50m (6ft x 4ft) will provide sufficient room for many sowings. Seedlings should be transplanted when they have made four or five true leaves and are about 6 inches high.

Allow 75 cm (2½ft) between Brussels sprouts, 45—60 cm (1½-2ft) between cauliflowers, whilst 60cm (2ft) can be allowed between kales; the spacing distance for cabbages varying from 30—38 cm (12-15ins).
