Fall Lawn Preemergent - Heavy Treatment Starts Now

How and when to apply fall lawn pre-emergents. LINKS → https://www.howtowithdoc.com/fall-pre... Lawn pre emergents should be applied once your lawn slows its growth and the temps start to fall. We like to wait until the first frost hits. At this time of year you can apply pre-emergents heavy because your lawn is entering the NO GROWTH zone and the impacts on your lawn are less. We apply the granular preemergent at a heavy rate and then water in. This locks the chemicals into the soil and prevents run off.
