Is your soil warm enough for Bermuda Grass?
Minimum needed: 70°F
Why soil temperature matters for Bermuda Grass
Soil temperature directly controls enzyme activity inside Bermuda Grass seeds. Below 70°F (21.1°C), germination slows dramatically or fails entirely—seeds may rot before they sprout.
When to plant Bermuda Grass in your region
Sow Bermuda Grass outdoors when your soil consistently reads 70°F (21.1°C) at 4-inch depth. For the fastest germination, wait until it reaches 85°F (29.4°C).
Signs your soil is ready
The easiest method is to track your local soil temperature forecast until it's predicted to stay above 70°F for the next 7 days—sign up for notifications when it's time to plant Bermuda Grass. For more precise readings in raised beds, pots, or different spots in the garden, push a soil thermometer 4 inches deep in the early morning.
