July marks an important transition for Arizona landscapes. After weeks of intense heat and dry conditions, monsoon season can bring welcome rain, higher humidity, and dramatic changes in the weather.

For homeowners, however, monsoon storms aren’t simply free irrigation. Heavy rainfall, strong winds, lightning, and rapidly changing soil conditions can all affect trees, palms, shrubs, flowers, and turf.

With a little preparation and regular attention, you can help your landscape make the most of the rainy season.

Monsoon Rain Doesn’t Replace Your Irrigation Schedule

When a storm moves through your neighborhood, it can be tempting to turn off your irrigation and assume your landscape has received enough water.

But not every storm delivers the same amount of rainfall.

Instead of automatically changing your irrigation schedule after every storm, check the soil around your plants.

Is the soil actually moist several inches below the surface? Did the rain reach the root zone? Or did water simply run off the surface?

Understanding what is happening in your soil can help you make better watering decisions throu

Watch for Water Runoff

Arizona soil can be difficult for water to penetrate, particularly when it has become dry or compacted.

During a heavy monsoon storm, water may run across the surface instead of soaking deeply into the ground.

Look for areas where water is pooling or flowing away from trees and plants.

If water is consistently running off, it may be worth improving the soil or adjusting your watering practices so moisture can reach the root zone more effectively.

Healthy roots need access to both water and nutrients, so getting moisture into the root zone is an important part of maintaining your landscape.

Inspect Your Trees After Every Major Storm

Strong monsoon winds can put significant stress on trees.

After a storm, take a walk around your property and look for obvious changes.

Check for:

• Broken branches
• Hanging limbs
• Cracked or split branches
• Newly exposed roots
• Leaning trees
• Damaged trunks
• Large amounts of fallen foliage
• Branches resting on structures or power lines

Don’t try to remove large or dangerous branches yourself. If you see a potentially hazardous tree or limb, contact a qualified tree professional.
