Lawn calendar – If you plan to water your fescue lawn this summer rather than letting it go dormant, fertilize in May (assuming you have not already done so). A slow-release form of nitrogen is ideal for applying 1 pound per 1,000 square feet, says Ward Upham of K-State. If you have to use quick-release, split the application into two, applying enough to give the lawn 1/2 pound nitrogen per 1,000 square feet in May and again in early June, Upham says.
Wild violets in lawns – If you are trying to get rid of wild violets in the lawn, many weed killers don’t cut it, Upham says; triclopyr is your best choice on fescue, though more than one treatment will probably be needed. Homeowners can buy it in such products as Turflon Ester and Weed-B-Gon Chickweed, Clover & Oxalis. But do not use triclopyr on Bermuda, or severe injury will occur, Upham says. Weed-B-Gon Chickweed Clover & Oxalis is labeled for buffalograss and zoysia, but lawns will likely show some temporary browning after application, he says. Spray only on calm days and when temperatures are below 90 degrees.
