Buckwheat: varieties, growing and uses
Buckwheat can fill a temporary summer plot with fresh foliage and small white to pale pink flowers. It is not a cereal grass but a member of the knotweed family. That different family makes it interesting when you want an alternative to familiar brassicas and legumes.

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

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.
