ROOTBLAST(R) 2-1-2 is designed to release nutrients quickly for fast root development in all plants young and old. Experts agree roots are the most important part of a plant because that's how a plant gets its water, nutrition and most of its oxygen. Rootblast is effective in producing bigger roots as well as new plant shoots creating optimal plant health for bigger plants and better yields. Use for seed germination, transplanting and to give your established plants a boost. Use once-per-season around all of your perennials, bushes and trees too. Follow up with Tomatoblast or Plantblast for extended feeding for the growing plant.
