Buckwheat: varieties, growing and uses

A summer filling, not a winter cover

Buckwheat suits an appropriate summer gap between crops. Its warm growing window and limited frost tolerance distinguish it from winter rye. Choose it for available time and crop, rather than just a flower photograph. Keep paths accessible and check the cover does not crowd neighbouring young crops. A small patch shows how quickly it closes over your soil.

Choose deliberately how much flowering to retain

Flowers can feed insects, while young growth is easier to incorporate. You can let one area flower and terminate another earlier if both fit your plan. This is not a recipe for maximum nitrogen: buckwheat is not a legume. When growing it as ground cover, prevent ripe seed reseeding your next vegetable bed. Give the following crop a clear start after incorporation.

Scent, flavour and use

For this green manure use, you do not harvest flour or salad leaves. Edible buckwheat products require separate, suitable food production and processing.

Care, cutting and harvesting

Sow during a suitable warm, frost-free growing window according to seed guidance. Allow room for emergence and prevent the young stand from drying out. Do not choose an overwintering plan for this frost-sensitive crop.

Cut or mow as a termination step; retain a flowering strip only if you can monitor seed formation.

Terminate before ripe seed creates unwanted volunteer plants and before the next crop needs the space.
