Weed Killer and fertilizer applied by a professional company
How do I rid my lawn of these products that were applied in error by Weed Man? They went to the wrong address.
Most of these products move through the soil with rain or watering or are inactivated by soil components but an important distinction is whether the company used immediate release or slow-release chemicals. In general, immediate/quick-release herbicides like Round-up are gone within 2 wks. Other herbicides persist for 30-60 days. You need to contact the company to learn the specifics of what was applied. Once you have this information, go to this website: https://extension.psu.edu/persistence-of-herbicides-in-soil. Also, the company should be falling over backward to give you legitimate references to answer your questions.
