Interpretation
What this means for your grass.
- Bermuda
- Soil is still hot. Avoid elemental sulfur and heat-stress products and keep irrigation steady. Buy your fall pre-emergent now so it is on hand when soil cools toward 70°F.
- Zoysia
- Soil is hot. Keep irrigation consistent and watch for brown patch. Have your fall pre-emergent ready for when soil cools toward 70°F.
- St. Augustine
- St. Augustine is still growing and the season is turning. This is the fall pre-emergent window: get it down before soil falls below 70°F. Check the label for St. Augustine tolerance before you buy.
- Cool-season
- Still too hot for cool-season grass. Hold fertilizer, keep irrigation up, and wait for soil to cool before seeding or feeding.
