In Arizona, spring is a critical preparation window for the months of extreme heat ahead. What you do in March, April, and early May directly determines how well your landscape survives through the brutal summer.
Irrigation System Check — Do This First
Before temperatures climb, run each irrigation zone manually and walk it while it runs. Check for broken spray heads, clogged drip emitters, and coverage gaps. Adjust timer schedules upward — summer irrigation in Arizona typically requires 30–40% more runtime than spring schedules.
Deep Water All Trees and Large Shrubs
Large trees and established shrubs should receive a deep watering — running drip emitters for 4–6 hours — before heat sets in. This moisture reservoir helps plants survive the transition to extreme heat and reduces stress during peak temperature periods.
Plan Your Monsoon Drainage Now
Arizona’s monsoon season (July through September) brings intense rainfall that can dump an inch or more in under an hour. Walk your property and identify low spots where water pools. Clear drainage channels and ensure your landscape grades water away from structures — addressing drainage before monsoon season saves significant property damage later.
