A Simple Guide for East Valley Homeowners
Weeds are one of the most persistent frustrations for Arizona homeowners, especially in rock landscapes. While post-emergent weed killer can eliminate weeds that have already sprouted, the best strategy is to stop them before they ever come up. That is where pre-emergent treatment comes in.
What Pre-Emergent Treatment Actually Does
Pre-emergent weed treatment refers to the application of a chemical barrier to your rock areas that prevents weed seeds from sprouting. It doesn’t kill existing weeds; instead, it stops new ones from germinating.
If weeds are already visible in your yard, those would require a post-emergent herbicide (weed killer) of which we offer Weed Control services. Pre-emergent is all about prevention.
How Our Team Applies Pre-Emergent
At The Yard Experts, our crews follow a consistent and effective process to ensure the treatment works exactly as intended:
-
Mixing the product
We combine the pre-emergent chemical with water at the correct ratio, which is approximately 1.5 ounces of product per gallon of water. -
Even application across rock areas
The crew then sprays all rock areas of the yard evenly so the chemical coats the surface where weed seeds typically sit. -
Activating the product with water
After spraying, we thoroughly douse all treated areas with a water hose. This step is crucial. The water helps the chemical seep into the soil, where it forms a protective barrier that prevents weeds from sprouting.
A Quick Note for Non-Maintenance Clients
If your yard is not on one of our recurring maintenance schedules, you will likely need a power blow before receiving pre-emergent treatment. Any debris on the rock—leaves, plant litter, dirt buildup—can interfere with the chemical properly absorbing into the soil. A clean surface ensures maximum effectiveness and longer-lasting results.
