We applied a pre emerge during the winter and it worked well. Its now spring and I want to know if I should apply it again. I think the label said it should last 3-4 months so I want to be sure I don’t get any weeds since the grass is looking great.
Stopping weeds before they ever grow is the best way to manage your lawn. Weed control is best handled before they germinate and the way to accomplish this is to use a good pre emergent. Though some products say they can last a year, it’s usually best to use one that will require a twice-a-year routine. This way you insure good coverage and protection in case there is something in your yard that makes the normal longevity of an application wear down prematurely.
As listed in the lawn section of our WEED CONTROL article, SURFLAN would be the best liquid to apply providing 3-4 months of weed protection. If you prefer to apply a granule, go with the WEED AND GRASS STOPPER. Both will last a few months and can be applied over most any grass.
Stopping weeds from ever growing is the best way to manage your lawn. It’s easier on all the plants involved, costs less in the long run and is quite effective given the excellent products we have on the market today.
