This very deep-rooting hardy green manure is a nitrogen fixer and has vigorous roots that draw up minerals from below the surface of the soil.  It performs well in drought-prone areas.

Alfalfa should be sown between April and July and dug into the soil when still green.  Sow before nitrogen-hungry crops such as brassicas.

To dig in - chop up the green manure with a spade and turn it into the top 10-12cm of soil. Alternatively, cut down and leave the clippings on the soil and cover to exclude the light using cardboard and grass cuttings or a biodegradable ground cover.  Leave for at least 6 weeks, by which point the green manure will have broken down and been incorporated into the soil by earth worms.


April to July

How to establish

The green manure should be cut down before flowering. It can be dug into the soil by turning over or left on the top as a mulch.
