Follow Nature's Bright Yellow Sign...the Forsythia Bush
Forsythia is a shrub with yellow flowers that is one of the first shrubs to flower in spring.
The rule of thumb is to apply springpre-emergent herbicidewhen Forsythia starts blooming. That's why every year we say, "Forsythia is the Signal."
In a typical year, if you don't have a Forsythia bush to signal you, apply pre-emergent between February 15th and March 1st to kill weeds before you even see them.
Any later than that window and it's too late to kill weeds with a pre-emergent herbicide (you'll have to switch to a post-emergent to apply directly to the weeds).
What does pre-emergent mean?It's an herbicide applied to the ground to stop emergence/sprouting of weed seeds so that you never even see the weeds.
Again, Forsythia is the Signal! Any later than March 1st and you'll need to switch to the post-emergent herbicide program until autumn.
ACT NOW due to the warmer soil temps.
