Step 2 - Help prevent the onset of Summer weeds by applying a pre-emergent herbicide. To save money, cross off step 1 and 2 together by buying a fertilizer already mixed with a pre-emergent herbicide.
Step 3 - Keep an eye out for fungus (Especially Grey-Leaf Spot and Brown Patch). If you have had problems before or have an area with extra shade or moisture, apply a fungicide with an active ingredient. Water 1 inch per week, either from natural rainfall or from inground irrigation. Overwatering your St. Augustinegrass can lead to disease.
Step 4 - We recommend homeowners to wait before they apply insecticide during the early stages of Spring. Monitor your St. Augustinegrass each week for chinch bugs since they are the number 1 enemy for St. Augustine. Chinch bugs usually start showing up in Summer through early Fall. If you get chinch bugs, treat with an insecticide that contains Bifenthrin or Carbaryl.
