IN WINDOWMODERATE CONFIDENCE
Warm-season late-spring nitrogen
Bermudagrass and zoysia start their main growth surge once soil temperatures stay above 65°F. A first nitrogen feeding here drives the dense, healthy canopy that crowds out weeds through summer. Feeding any earlier just pushes weak growth.
Shallow soil temperatures are in the action band at 83.8°F at the Tucson 11 W sensor, 64 miles from your location.
Window: Apr 1 to May 31. Window typically open for 2 to 3 weeks.
