I was a firm user of Miracle-Gro® until you sent me Bountiful Harvest® Prebiotic. I started using it on ½ of my houseplants and after just one use I noticed a great difference. The plants with the Bountiful Harvest® perked up and flowered whereas the others did not. The plants were even potted in a Miracle-Gro® food released soil so I thought there would be no or little difference. I like the idea of the Bountiful Harvest® being liquid and adding an ounce or two to the water. It is much less messy than the blue Miracle-Gro® powder I use to use.
