What is the best time to apply pre-emergent weed killer granules in the spring?
Folks are really asking early this year.
Timing varies with where you are in the state.

Pre-emergent application normally should be 2 or 3 weeks prior to that time.
Add the second, “booster shot”, would come 90 days later.
