Sowing a green manure on bare soil in autumn is a great way to improve its structure and fertility. It prevents nutrients from being washed out of bare soil, deters weeds from germinating and improves soil structure.

Sown directly, the resulting young leafy plants are later dug back into the soil in spring, giving it a boost.

Discover how to sow green manure in just three steps, below.
