New Bermuda Sod Has Weeds? Wait Until You've Mowed Three Times Before Spraying

Timing Is Everything for Weed Control on Fresh Sod

Your December-installed Bermuda sod hasn't greened up yet, but weeds are popping up. Can you spray now? No. New sod is extremely sensitive to herbicides. Applying too early damages or kills the very grass you're trying to establish.

The Three-Mow Rule

Wait until you've mowed the new lawn three times. This ensures:

• Roots have knit into the native soil
• Grass plants have recovered from transplant shock
• Leaf tissue is mature enough to metabolize herbicide safely

Until then, hand-pull weeds or spot-treat with a paintbrush-applied glyphosate on individual weeds—avoiding sod contact. Patience now prevents dead patches later.
