When to Apply Pre-Emergent in Murfreesboro TN
For crabgrass prevention, timing matters more than the product—here’s when Murfreesboro lawns typically need pre-emergent and what to do if you’re late.
Pre-Emergent Timing Guide for Murfreesboro Lawns
Start Watching in Late Winter
Pre-emergent timing is based on soil temperature, not a warm weekend. Crabgrass germination is closely tied to soil temps reaching the mid-50s consistently.
Ideal Application Window: Late February Through March
UT turf guidance notes that pre-emergent applications in Tennessee are commonly made in late February through March before crabgrass germination.
Water It In for Best Results
Pre-emergent products need to be activated. UT guidance notes roughly 0.5 inch of rain/irrigation within 24–48 hours after application helps activate the barrier.
If You’re Late: You Still Have Options
Rutherford County Extension notes crabgrass often begins germinating in March, but not all seed germinates at once—applying pre-emergent later can still help. They also suggest using a combination of pre-emergent and post-emergent if seedlings are already up.
