I have raised vegetable garden beds and a few weeks ago experienced a large wildfire where the vegatation and homes on all sides of us burned as did the structural aspects of three of my beds. Needless to say there is a lot of ash in the air as well as visibly on the soil in my garden. My question is should I dispose of all the soil in my beds prior to planting new vegetables? Is my soil toxic? Should I throw away the vegetables currently growing in those beds?
