Lawn Preemergent Application and Timing
When to apply your lawn pre-emergent.
Doc explains the QUARTER year method of using and applying lawn preemergent. Using the 3 month or quarter year timing method we can better understand when we should apply preemergent to our lawns. It’s always best to apply your preemergent a little earlier.

How Preemergents Work
Preemergents have NO EFFECT on weed seeds.
Most preemergence herbicides will last between 8 and 12 weeks; however, some last longer and some shorter. Check the label and your Cooperative Extension agent for re-application guidelines in your area.
Preemergent herbicides which control grasses and a few broadleaf weeds may be used in many different planting situations, but those which are better on broadleaf weeds injure many ornamentals. More caution is needed when dealing with those herbicides or in planting situations (herbaceous perennial beds) where sensitive plants will be planted.
