Sowing Guide

Before sowing, lightly tread over the recently raked soil. Scatter the seeds as evenly as possible over the surface.
Lightly rake the surface to cover the seeds.
Pat down the area with the back of a spade or if preferred use a roller.
Water the newly sown seeds well.

Growing On

Water the young seedlings well until established.
Established plants need regular watering especially in dry conditions.
Autumn sown clover will survive as small plants over the winter months. Once spring arrives they will start to grow once again.

Digging In

The plants can be cut down using a garden spade, sheers, a lawnmower or strimmer after 2 - 3 months of growing. (ideally before flowering)
Leave the cut foliage on the surface to wilt for a few days.
Dig in using a sharp spade to the depth of 20 - 25 cm. Or if preferred use a rotovator to incorporate the organic matter.
Leave the green manure to decompose in the soil for at least 3 - 4 weeks before growing any vegetables in the soil.


If some clover plants are left to flower, they will attract butterflies, bees and other beneficial insects into the garden.
