Crimson Clover Growing Guide

Trifolium incarnatum

Crimson Clover

Crop Rotation Group

Legumes (Pea and Bean family) 


Any well drained soil.


Full sun.

Frost tolerant

Established plantings made in early autumn can tolerate temperatures to -18 C (0F).


When using crimson clover to improve very poor soil, mixing a balanced organic fertiliser into the soil before planting will give better results. Using inoculated seed can also help to grow a vigorous stand.


Often planted with hardy annual flowers including bachelor buttons and corn poppies.


Single Plants: 10cm (3") each way (minimum)
Rows: 10cm (3") with 10cm (3") row gap (minimum)

Sow and Plant

Sow in late summer so that plants can become established before cold weather comes. In cold climates, crimson clover can be planted in early spring instead of autumn. Broadcast seed into cultivated soil so that the seeds are about 5 cm (2in) apart and 1 cm (1/2in) deep. No thinning is required.
Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.


Crimson clover is one of the most beautiful cover crops you can grow.


Take down plants just as the red tops begin to fade, but before the plants produce mature seeds. The easiest method is to slice plants off at the soil line with a sharp hoe. They can then be turned under or composted. Nitrogen nodules left behind in the soil add fertility.


Crimson clover plants become quite tough as they age, but they seldom regrow when cut off at the soil line.
