ok...ok Humic Acid. I sprayed my entire garden including my fruit trees with it. Remember Mary, Carl Seacat said he fertilizes with fish and humic acid when the temperatures start to go up. I have a blend of fish and kelp from Neptune's Harvest that I like because it is made with a cold press process to preserve the goodies that the heat processing of the cheaper brands destroy. I had to get that online. And, I have read in several places that plants sprayed with kelp make it through the heat of the summer better. I used it last summer and thought that it did help.
