Getting Rid of Crown Vetch
Several years ago we planted crown vetch as a groundcover on our berm. It has since taken over and invaded our landscape. We have tried a variety of chemicals to kill the plants. They don't seem to slow it down a bit.
Mowing or a combination of mowing and herbicides should solve the problem. Mow the crown vetch in June and again in August. It may take several years to kill all the existing plants and their seedlings. Or mow in late spring and treat with a total vegetation killer. Whether using traditional or new environmentally friendly products read and follow label directions carefully. All these products are plant killers and can injure or kill your desirable plants as well as the weeds.
