That was an inappropriate use of the product since Weed B Gone is meant to used to control "weeds" in lawns, not flower gardens, even if there are no plants growing there. Weed B Gone is also a contact poison so spraying it on soil that has no growth is a waste of time, energy, and money.

The manufacturer says to not reapply this product for 2 weeks and to only apply it twice a year and no more. You probably could plant 2 weeks after those "lawn guys" misapplied the product.

Yeah, I had told them not to put anything. But there were multiple people and one got over-zealous -- it happens. These weed killers typically have been as effective for me as off the shelf cold medicine crap, but I bet if I seed the area they will very effectively kill off the seeds. Now I need to worry about nursing the plants that will be remain in the pots for the next few weeks.

Depending on how much they applied is the big ?. If it was a small amount you should be safe to plant as long as you do not back fill with the top 2" of soil. If they used a high rate you will not be able to replant anything but grass for about 9mo-a year.

Weed B Gone has no affect on plant seeds, it needs to contact the plants leaves to be effective. They can kill off the newly germinated plants however.

If you used a licensed lawn care company someone there must be a Licensed Pesticide Applicator and that one of their employees wrongly applied a plant poison says proper supervision was not in place. I would not use those people again.

"If they used a high rate you will not be able to replant anything but grass for about 9mo-a year."

This is a bit on the pessimistic side :-) The active ingredients in Weed-B-Gon degrade quite rapidly in the soil......anywhere from a few days to a few weeks. To be on the safe side you could wait a month before planting but there is NO need to wait longer than that. As stated above, the herbicide must come into contact with plant foliage to be effective - it has minimal residual effectiveness if applied to the soil.
