Plant Success Granular consists of 10 beneficial species mycorrhizae and trichoderma. High quality biostimulants (including kelp meal, humus, vitamins and amino acids) are added to improve effectiveness. Working together, beneficial fungi expand into the soil and greatly increase the root's ability to absorb water and nutrients to increase flowering and fruiting. Use the handy shaker to apply 1 tsp. per row foot in furrow, 1/2 teaspoon per transplant, or 4 oz./cu.ft of potting soil. The fertilizer (3-1-2) in Plant Success Granular helps give your new plantings a head-start.
