“When is the proper time to apply fertilizer to centipede grass? Should I use a weed and feed product?” – Bill
Centipede grass is a warm-season turf grass, which means its growing season begins in late spring and lasts through the summer, then it goes mostly dormant or brown for the winter. The beginning of the growing season is called “green up,” as the grasses once again send up bright green blades and the lawn starts actively growing.
Although usually occurring in April, the exact timing of the spring green up depends on the temperatures in your particular microclimate. During the green up period, the new growth in your lawn is very tender and can be harmed by the broadleaf herbicides in weed and feed products. In addition, feeding too early can cause growth that may be damaged by late cold snaps.
The ideal time to apply fertilizer, or weed and feed products, to centipede grass is a few weeks after green up, but before temperatures start topping 85° F. That’s usually around mid-May, but let your lawn be your guide. Here are a few tips to keep in mind:
- Weed and feed is difficult with centipede grass, because the grass does better with a late application, but weeds are more affected by an earlier application – giving a narrow window of time for good results.
