I put Vigaro Weed & Feed on my burmuda grass one week ago. There is a wide swatch in my yard that has not 'greened up' and stil looks winter-brown. I thought it was supposed to green-up within a couple days. I read the directions on the package and watered appropriately. Have i killed my burmuda grass? How long do i wait before i know if its dead? What else can I do now? |
