Phoenix Winter Lawn Transition: Midiron Bermuda + Rye Overseed

A Phoenix homeowner has Midiron Bermuda sod overseeded with perennial rye. Temps are dropping (highs ~65°F). They want to know how to help the rye and when to reseed for summer.

Key clarification: Bermuda doesn't *die* in winter—it goes dormant (hibernation). The rye provides winter green.

Rye care now:

• Water daily until mowed 2–3 times
• Apply starter fertilizer when blades reach ~1″
• Mow at 1.5–2″ for best density

Spring transition (no reseeding needed):

• When temps hit 85°F+ consistently (usually April), stop watering for 10–14 days
• Rye dies out completely
• Bermuda wakes up and takes over naturally
• Resume normal Bermuda watering/fertilizing

One fall overseeding per year is all this system needs. The Bermuda is perennial—it returns every spring from its root/rhizome system.
