This product is one half of my "Magic Formula" that I guarantee customers will bring back their sickly and ugly plants. I'm a cheapskate so a few ounces for $15 bucks is a hard pill to swallow ... But I'm still buying it, and that my friends should tell you something. Combined with the Southern Ag 20-20-20 in a light mix will make magic happen! Trees, shrubs, perennials and the turf just love it! I drill a few holes around the ugly tree/shrub then hit the entire area with this mix ... If it's been dry water the area the day before or go the day after rain as roots need water to process the fertilizer...water again in a few days and in a very short time you will be thinking that your Merlin the Magician! May your gardens grow half as good as your weeds, David
