Cool season legumes make most of their biomass in late winter, early spring and in the autumn of the year when temperatures and rainfall are generally more favorable. Cool season perennial legumes usually do not persist more than two to three years in the southeastern Unites States. Bloat is a problem with some legumes, so gradual introduction to new pastures, mixture with grasses, and bloat blocks are recommended.
