Keep bermudagrass mowed between .5 and 1.5 inches.
Apply pre-emergent herbicide. This will cut down on summer weeds.
If you have had insect problem in the past, treat with broad-spectrum insecticide. If you use a granular variety, water the lawn immediately after application to help get it into the soil.
Don’t overwater. In the active growing season, bermudagrass needs about 1″ of water a week, from natural rainfall or irrigation. Too much water can cause fungus.
Apply fungicide (if needed). If you have had a fungus or disease in your bermudagrass in the past or have quite a bit of shade in the yard, you should apply a systemic fungicide to prevent future outbreaks.
Fertilize your lawn with Lawnifi, the recommended liquid fertilizer.
