Clover: Sowing, planting and harvest calendar
When and how should you sow clover outdoors?
Before sowing clover outdoors, identify the type you have chosen and its intended use. Perennial white clover, red clover and usually annual crimson clover do not all share the same sowing season or seed rate. Choose a time when the soil is moist, no longer waterlogged and warm enough for germination. Spring or late summer may suit the species and climate; an autumn sowing needs enough time to establish before severe frosts.
Remove competing weeds and prepare a fine, level, firm surface without working sodden ground. The small seeds need good contact with the soil. Use the seed rate stated on the packet for your species and purpose. For an even broadcast sowing, divide the seed into two portions and make passes in crossing directions. Do not apply a universal spacing of 15 to 20 cm between individual seeds.
Cover very lightly, following the sowing depth for your chosen type, then firm gently. Burying every clover seed 2 cm deep would be too deep for many types. Water with a fine spray if needed and keep the surface moist during emergence, without puddles or runoff. Avoid a thick layer of mulch that would obstruct the emerging seedlings.
