Sowing & growing

Sow directly where it is to grow from March-Sep. Scatter the seeds on a weed-free bed and cover with 1cm of soil. Water well and keep moist until germinated. As a green manure, it should be dug up and dug in before flowering, while fresh and green, and then left for a month to break down and improve the soil.

Aftercare

If sown in Autumn, can overwinter as groundcover and be dug in as green manure.
