March: Plant, transition turf, open the pool for real.
March is when the Valley genuinely comes alive. Bermuda starts greening, daytime temps hit the 70s–80s, and pool use returns. This is the month to plant nearly anything desert-adapted, refresh hardscapes, and tune irrigation for the long warm-up.
What to do — and why it matters in Arizona.
Plant trees, shrubs, succulents, and turf.
Six to ten weeks of mild weather to establish before May heat — the widest planting window of the year.
Transition: scalp rye, fertilize bermuda lightly.
Scalping by mid-March lets sunlight reach bermuda crowns; light N feeds green-up without burning.
Increase drip run-times ~20% from winter.
Roots are pushing growth; under-water now and you lose spring color.
Bump pump to 6–8 hrs/day, full chemistry rebalance.
Algae pressure rises fast as water passes 65°F.
Re-aim landscape lights to new tree canopies.
Spring growth changes shadow angles within weeks.
Power-wash travertine and pavers.
Removes winter mineral haze before sealer reapplication.
Book the right month for the right build.
Arizona project timing matters more than most homeowners realize. Excavation lead times, plaster cure windows, monsoon prep, and HOA approvals all push optimal start dates 2–9 months ahead. Here's what to lock in this month for smooth delivery.
- Summer-finish pool projects — book by mid-March for July plaster.
- Permanent outdoor lighting before summer entertaining.
- Misting systems and shade structures ahead of May heat.
