When first planted, water daily to speed germination and help establish a strong root system. Sweet clover is an abundant seed producer and seeds can remain viable for 30-40 years, giving it a competitive edge. Because white clover fills voids in grass stands, forage yields are often increased, particularly when tall fescue and orchardgrass stands have thinned.

Avoid applications of nitrogen fertilizer or poultry litter while clover is establishing as this will favor grass growth and increase competition. Spring seeding should be done in early spring, about oat-planting time, because sweet clover seed requires a good supply of moisture and cool temperatures for germination and early seedling growth. Woven black landscape fabric can In contrast, low yielding clovers (for example, "white dutch" or common cultivars) do not typically furnish adequate amounts of high quality forage in many Georgia environments.
