Whether you’re maintaining your current yard or planning improvements, here’s what Arizona homeowners should know.

Quick Answer

To keep your Arizona landscape healthy during the summer:

Water deeply and adjust irrigation schedules for rising temperatures.
Water in the early morning to reduce evaporation.
Add or replenish mulch to help soil retain moisture.
Choose drought-tolerant plants that are adapted to Arizona’s climate.
Inspect your irrigation system regularly for leaks or broken sprinkler heads.
Prepare your yard for monsoon storms with proper drainage.

Why July Is the Hardest Month for Arizona Landscapes

July combines several challenges that can quickly damage a landscape:

Triple-digit temperatures
Increased evaporation
Monsoon storms
Higher water demand
Irrigation systems running at peak capacity

Even a small irrigation issue can cause plants to decline in just a few days.

Adjust Your Watering Schedule

One of the biggest mistakes homeowners make is leaving their irrigation controller on spring settings.

As temperatures climb, plants require deeper watering to encourage roots to grow farther into the soil.

A few general best practices include:

Water early in the morning.
Water deeply rather than frequently.
Inspect irrigation weekly during summer.
Replace broken emitters and sprinkler heads immediately.

An irrigation audit can often identify problems before they become expensive.

Mulch Is One of the Best Investments You Can Make

A fresh layer of mulch helps:

Keep soil cooler
Reduce evaporation
Prevent weed growth
Improve soil health over time

Even adding a couple of inches around trees and shrubs can significantly reduce water loss.

Choose Plants That Love Arizona

If you’re constantly replacing plants every summer, the issue may not be your maintenance—it may be your plant selection.

Many beautiful landscapes feature:

Texas Sage
Red Yucca
Desert Spoon
Agave
Desert Marigold
Lantana
Baja Fairy Duster

These plants provide color while requiring less water than traditional landscaping.

Don’t Ignore Your Irrigation System

Just like your home’s air conditioner, irrigation systems seem to fail when you need them most.

Watch for signs such as:

Dry patches in your lawn
Water pooling around sprinkler heads
Broken emitters
Sprinklers spraying sidewalks
Higher-than-normal water bills

Fixing small issues early can save both your landscape and your wallet.

Prepare for Monsoon Season

Arizona’s monsoon storms can deliver heavy rainfall in a short amount of time.

Proper grading, drainage, and landscape design help move water away from your home while protecting plants from erosion and standing water.

If your yard floods during summer storms, now is the perfect time to start planning improvements before next season.

Summer Is the Perfect Time to Plan Fall Projects

Many homeowners wait until October to begin planning a landscape renovation.

Unfortunately, that’s when everyone’s calling.

July is actually one of the best times to schedule:

New patios
Outdoor kitchens
Fire pits
Putting greens
Irrigation upgrades
Complete landscape renovations

Planning ahead helps ensure your project is completed in time to enjoy Arizona’s beautiful fall weather.

Frequently Asked Questions

How often should I water plants in Arizona during July?

It depends on the plant, soil type, and irrigation system. Most established trees and shrubs benefit from deeper, less frequent watering rather than shallow daily watering.

Why are my plants dying even though I’m watering them?

The most common causes include irrigation problems, watering too frequently, poor drainage, heat stress, or plants that aren’t suited to Arizona’s climate.

Is July a good time to install landscaping?

Planning and designing your project during July is ideal. Many homeowners use the summer months to finalize plans so installation can begin as temperatures become more comfortable.

Should I replace my irrigation system?

If your system frequently leaks, creates dry spots, or struggles to keep your landscape healthy, upgrading to a more efficient irrigation system can improve plant health while reducing water waste.
