Pre-emergent treatments help prevent future weed growth* by killing new seeds so weeds aren't constantly popping up during rainy seasons. The rainy seasons in Arizona begin in January and June, and these treatments typically last about 5-8 months, but we only recommend doing them annually.

​

*Please note: pre-emergent treatments will not get rid of any existing weeds that are currently in the rocks. Pre-emergent treatments do not work on grass-type weeds.

​

Pre-emergent treatments are also available for the grass area, These are a bit more tricky timing-wise, so please contact our office directly if you are interested in scheduling one.
