I’ve read other threads regarding Miracle gro...but most seem to deal with using Miracle gro potting soil as a substrate. This is my question. I’d like opinions on using the fertilizer on plants that will eventually be used as food. Case in point...a Rose of Sharon ( hibiscus). I’ve always been quite impressed with Miracle gro’s results ( easily double the foliage compared to no fertilizing) when used on ornamentals. I could definitely use a bumper crop of hibiscus flowers..with all the faces that need feeding. There are two possible feeding methods...pour the MG solution at the base of the plant or spray the entire plant ( which gives the best results by far). Ideas? Thoughts?
