This would mean inspecting all of your lawn and applying a weed killer only on individual weeds, and using the mildest formula possible. Mowing and watering Mow twice a week. This encourages a thicker, healthier lawn that is more resistant to weeds and pests. Higher grass blades crowd out weed seedlings. Make sure the mower blades are sharp.
Dull blades tear the grass, leaving it susceptible to disease.
Leave the grass clippings. They recycle moisture and nutrients back into the lawn. Place 2 to 3 inches of mulch around the base of shrubs and plants to reduce water evaporation. Water your lawn only when necessary. If you must water, do it in the morning.
