Q.Roof Cleaning Solution On Vegetable Garden

Zone Bryn Mawr, PA 19010 | Anonymous added on June 17, 2021 | Answered

We had our roof cleaned 2 days ago. The company used a combination of 3% sodium hypochlorite (Clorox) and surfactant (RoofSnooty). While they took care to protect the plants in the area by continually dousing them with water (they look fine), some of the solution made it over the roof and onto our vegetable garden. The next day we noticed some burning of the leaves on a variety of plants most all appear to be alive (see attached picture). We washed the plants and the area down several times with water and today, a day later, they appear unchanged (no better but no worse). The question is did we take all of the appropriate steps to save the plants (tomatoes, zucchini, beans, perennial and annual herbs), and are the vegetables safe to eat going forward? Is there anything else we need to do to remediate the soil?

It sounds like you have done all that you can. If there is enough in the soil to do any damage, it will not allow for your plants to make it far enough for you to consume. If you get anything from your plants, it will mean that there isn't enough in the soil to make a difference.

Unfortunately, there is not much to be done in this situation.
