Depending on where you live, fall pre-emergent applications should be done between August and November when the soil temperature is below 70 degrees and dropping. You should also apply a pre-emergent in early spring usually between Ferbruary and late May after the ground has thawed from winter but before he soil temperature has reached 55 degrees up to 65 degrees.
We do have a general Lawn Care Schedule Calendar for Warm and Cool Season turfgrasses or you can always reach out to your local extension office for best timing in your area.
