Not unless you're using actual chunk charcoal. If you are using briquettes, they are loaded with coal dust, which is why you get that sulfur smell as they are burning, and it will be acidic as hell, which is why everyone's Weber gets holes eaten through the bottom; it turns into sulfuric acid when it gets wet. It would be good for blueberries or redwoods though, as they have a pH requirement of 4.5.
