Is there a way to make my soil weed killer free once it has been sprayed with Round Up
I had planned to grow my own vegetables when I found that the soil has been sprayed with "Round Up" weed killer. What do I have to do to cure the soil and make it healthy again?

Residential weed killers, like Round-up, must break down in the soil within a week or two, so unless it was commercial grade, it should not cause an current issue in the soil.
As always though, to improve the health of the soil, add organic material like compost or composted manure. Buying a container of earthworms from a bait shop and adding them to the soil will also help keep the soil healthy.
