Moore Green includes a soil wetting agent in its BASIC and PLUS Lawn Programs during the summer months. We have found that during the summer heat, lawns show less drought stress when a soil wetting agent is used. When a soil becomes dry it can actually repel water. Soil wetting agents allow the water to quickly enter into the soil and work its way deep into the root zone. The deeper the water goes, the roots will follow, causing a thick and lush lawn.
