Q: Does vetch come back every year?
A: Tilling the vetch under, letting it decompose and then planting your crop will go one step further by adding organic matter to the soil. Hairy vetch, as a winter annual, will sprout in the fall, overwinter, regrow in spring, go to seed and die.

Q: Can you mow crown vetch?
A: A combination of mowing and herbicide is fairly effective. Note the word “fairly.”” Mowing close to the ground can control the spread of crown vetch branches and spring is a good time to do this – like now – the mowing will knock it down and cause it to grow again and again.”

Q: Is Crown vetch toxic to animals?
A: Crown vetch contains nitroglycosides which is poisonous to horses and other non-ruminants. Ruminants are not affected because they are able to convert the toxin in the rumen.

Q: What damage does the crown vetch do?
A: Problem: Crown vetch becomes a problem when it invades natural areas, such as na- tive grassland prairies and dunes, where it works to exclude native vegetation by fully covering and shad- ing those native plants. It can climb over small trees and shrubs, and eventually form large monocultures.

Q: Is vetch good for the garden?
A: Few legumes contribute as much nitrogen or biomass to the garden. Vetch produces an abundance of vining stems and fine foliage that help protect soils from wind and rain, while improving structure and adding nutrients. Plant vetch as a cover crop or green manure and reap the rewards of healthy, thriving soil.

Q: Is crown vetch a good plant?
A: Crown Vetch (Coronilla varia) – An extremely fast and aggressive plant, Crown vetch produces a quick ground cover for erosion control with white to pink flowers. This legume should be planted for erosion control in certain hard-to-reach areas such as steep, dry, rocky slopes and low fertility soils.

Q: Is crown vetch poisonous to dogs?
A: Crown vetch contains the toxin beta-nitropropionic acid (3-NPA) primarily in the leaves and growing stems. Ruminants are able to detoxify the 3-NPA in their rumens, while simple stomached animals cannot. The 3-NPA once absorbed will cause methemoglobinemia.

Q: Does crown vetch stay green in winter?
A: It is green from early spring through late fall and dies back in winter. When it blooms in summer, its white, purple and pink flowers attract bees and other pollinators. Crown vetch is hardy in U.S. Department of Agriculture plant hardiness zones 3 through 9 and can be invasive.
