Question 1

What's the difference between pre-emergent and post-emergent?

Accepted Answer

Pre-emergent creates a barrier in the soil that prevents weed seeds from germinating — it stops weeds before they start. Post-emergent is applied to kill weeds that have already sprouted. For best results, we recommend pre-emergent treatments in fall and spring to prevent the majority of weeds.

Question 2

When should I apply pre-emergent in Arizona?

Accepted Answer

Arizona has two primary weed seasons. Apply pre-emergent in late September to early October for winter weeds, and again in late February to early March for summer weeds. Timing is critical — applying too late means weeds have already germinated.

Question 3

Will weed control kill my grass or plants?

Accepted Answer

Our treatments are designed for desert landscaping, gravel areas, and rock yards. If you have grass or ornamental plants, let us know so we can use selective herbicides or careful application to protect desirable vegetation while eliminating weeds.

Question 4

How long does weed control last?

Accepted Answer

Pre-emergent treatments typically provide 3-4 months of protection, which is why we recommend two applications per year (fall and spring). Post-emergent kills existing weeds but doesn't prevent new ones, so combining both approaches gives the best long-term results.

Question 5

Do you service gravel and rock yards?

Accepted Answer

Yes! Gravel, rock, and desert landscapes are actually ideal for our weed control treatments. Without grass to protect, we can apply more effective broad-spectrum treatments that keep your yard completely weed-free.
