What does Weed Impede do?
It is a preemergence product that prevents weeds in your landscape ornamental areas for up to 6 months.

What weeds does Weed Impede control?

Weed Impede is primarily a grass killer, but it is quite active on broadleaf weeds such as pigweed, purslane, spurge, oxalis, and many others.
Will Weed Impede control weeds that are already up?
No. If weeds already exist (and no ornamentals have been planted) you might want to consider a tank-mix with a glyphosate product like Monterey Remuda or Roundupâ. These products will kill the existing weeds and Weed Impede will go into the soil to prevent those that have not yet germinated.

Generally twice a year, once in the fall prior to the rainy period, and once again in the spring after the bedding plants are put in (depends on length of growing season).

Over 175 species of ornamentals are on the Weed Impede label. These include bedding plants, ground covers, shrubs and trees.

What species should I not use Weed Impede on?
Specifically, Weed Impede should not be used on slender Deutzia, Douglas fir, Techny aborvitae or Eastern hemlock.
Can Weed Impede be used in my vegetable garden?
