HAIRY VETCH
Hairy vetch is used as a winter cover crop to improve
the soil's structure and nitrogen content when tilled in or turned over
in the spring.
Hairy vetch is often sown as seed in late July through
August. Plants will germinate and develop shoots and root through the
fall. Vetch will go dormant during the winter months; a severe winter
with below 0 degrees F. may kill the plants, limiting the need for burn
down in the spring.
Plants surviving the winter can be rotortilled or
plowed in the spring. Dense populations can be knocked down with an application
of 2,4-D; hairy vetch is quite sensitive to herbicide applications.
Vetch may flower and produce seed that will germinate.
Cultivation or spot treatment with 2,4-D can control the problem. Make
sure to read and follow all labeled directions when using a pesticide.
Hairy vetch is NOT the same as crown vetch, though
both are legumes and will improve the soil fertility.
