pre-emergent must be applied to the soil and watered in before weed seeds begin to sprout.
A pre-emergent can be purchased at your local garden store and applied to your lawn using a fertilizer spreader. The product should be effective for approximately two months. Be sure to follow all instructions carefully.
When should I fertilize my lawn?
Applying fertilizer too early in the growing season will encourage spring weeds, and do very little for the grass that is emerging from dormancy.
According to Dr. Hennon Cummings, Director of the Turfgrass Management Program at Tarleton State University, “If you aren’t sweating, it’s too early. Fertilizer should be applied after the grass has grown enough to require mowing at least four times. If you want greener grass prior to then, you should apply iron.”
