Is it too late to put a pre-emergent on my lawn?
And, why do I need two pre-emergent applications in the spring?
“Is it too late….” Is the most asked question we receive this time of year.
The answer…. ”It is never too late to start a lawn care application program!”
In central Oklahoma it is always our goal to have the first pre-emergent on the lawn by the first week of March. Why? For the best lawn prevention of crabgrass is important.
Crabgrass germinates when soil temperatures reach 55 degrees for 3 consecutive days, which is typically mid-March in central Oklahoma. This year soil temperatures are right on schedule. For the last three days, soil temperatures in central Oklahoma have been at or above 55 degrees.
