ShellyS said:I am contemplating putting several raised beds atop a large gravel bed. I am worried that herbicide or other chemicals have been put on the gravel previously. Can I "wash" the gravel or place something over it before I place my boxes? Thanks so much!!!!
Shelly. How deep will your raised beds be, and what will you be growing in them? If vegetables, then the concerns would be different from ornamentals. I don't think "washing" would help much because presumably the gravel gets washed every time it rains. It's a difficult question to answer without knowing what kind of herbicide or other chemical might have been used there. Are you suspicious because there are no weeds?
