Hairy vetch is one of the most winter hardy legumes. Being more winter hardy than common vetch, hairy vetch has the potential to withstand temperatures in excess of 5F with no cover. This species is known to have a great rooting system, with a tap root that will extend 1 to 3 feet into the soil profile. This taproot will allow the vetch to thrive even in dry conditions. When hairy vetch is placed into a mix, it can help bring the C:N ratio of the mixture down. This reduces the risk of nitrogen immobilization for the next crop.
