I have gotten a lot of questions about weed control this week! Wild violets are winter annual or perennial weeds that often grow in clumps. The plants form rhizomes that support heart-shaped leaves. The flowers of wild violet have five petals and are usually purple, but can also be white or yellow.
It can also be one the most difficult weeds to control in lawns!
Combination products that contain 2,4-D, MCPP and Dicamba such as Trimec, Weed-Out and most formulations of Weed-B-Gon do not do a good job. Products with triclopyr give much better control though more than one treatment will likely be needed.
A couple of products that contain triclopyr on the homeowner side are Turflon Ester and Weed-B-Gon Chickweed, Clover and Oxalis. (Note: There are several formulations of Weed-B-Gon but only Weed-B-Gon Chickweed, Clover and Oxalis contains triclopyr.)
Both products listed above are labeled for tall fescue and Kentucky bluegrass.
Do not use products containing triclopyr on bermuda grass as severe injury will occur.
Weed-B-Gon Chickweed Clover and Oxalis is labeled for buffalo grass and zoysia (Turflon Ester is not) but lawns will likely show some temporary browning after application.
Spray only on calm days and when temperatures are below 90 degrees to avoid damage to nearby plants. Be sure to read and follow product label directions.

Have a great weekend!
