Velvetleaf (Abutilon theophrasti) is common not just in agricultural fields, but also gardens and lawns. It is a weed that is difficult to control with herbicides since herbicides do not kill 100 percent of the velvetleaf. However, if you combine the use of an herbicide, such as Roundup, with a mechanical control, you can kill most of your velvetleaf, plus control its spread and keep its presence manageable and less intrusive.
Mow velvetleaf or cut it down with clippers before it flowers, usually in late summer. Pull up as much as you can.
Wait to apply the Roundup on a calm day and when rain is not expected.
Put on rubber gloves, goggles, long sleeve shirt, socks, shoes and long pants.
Spray the cut velvetleaf with a Roundup product, such as Roundup Ultra, that is suitable for the site where your velvetleaf is growing. Read the label and following application rates for the size of your area and type of Roundup you are applying. Spray with even sweeping motions over the top of the plants.
Repeat mowing and spraying if you notice new velvetleaf growing.
