Q.Weed Killer by Method of Spray

Anonymous added on April 8, 2014 | Answered

Bought today one of those weed controls sprays that connects to garden hose. I did my entire front yard but now I’m worried about the rain that it is coming to San Antonio, Texas this comming Wed. could hurt my live oak in the front yard. Would the chemical hurt any trees? I’m not planning to water my grass tomorrow to make sure most have evaporated. How long does this type of chemical stay in the soil? (Spectracide- weed stop for lawns) I read your article where it says it usually takes 24 to 72 houes to evaporate. Should I be worried?

I think much of it should be evaporated by then with the remaining washed away by any incoming rain. I would not expect this to have a major effect on your oak tree.
