The Arizona Overseeding Schedule

If you book a golf trip to Phoenix or Scottsdale in October, you are making a mistake.

Desert courses transition from Bermuda grass (summer) to Rye grass (winter). To do this, they scalp the Bermuda down to dirt, plant Rye seeds, water it constantly, and close the course for 2-4 weeks.

When they reopen, it's Cart Path Only for at least another 2 weeks to protect the fragile baby grass. Rounds take 5.5 hours.

The Timeline

Phase	Timing	Impact
Scalping	Late Sept	Thin, brown lies. Fast but ugly.
Closure	Oct (varies)	Course closed entirely.
Reopening	Late Oct / Nov	Lush green, but strictly Cart Path Only.
