What is the difference between a 6, 9 and 12 month pre-emergent warranty, and why would I want one over the other?
The manufacturers clearly state that the pre-emergent material lasts only 6 to 8 months. In our climate we can usually expect 9 months of good weed control. Some clients never want to see a weed. If this is the case an application every 6 months will give the best opportunity to be weed free. Most people without heavy weed problems choose the 9-month warranty because of the economics, however, there is a higher risk of having some weeds. Since the material doesn t last 12 months we don t offer this option. We want our clients to be happy and a 12-month warranty isn t going to achieve this. We know from years of experience that if you treat only once a year you will be experiencing at least 3 months of that year with no pre-emergent barrier. Please Note: Our warranties apply to annual weeds only. Annual weeds grow from seeds. Perennials like Bermuda grass and nut grass have root systems and will grow back. For information regarding the control of perennial weeds look further down.
