What makes Bio-Tone Starter Plus special

What distinguishes this formula is the inclusion of both endo and ecto mycorrhizae. These beneficial fungi associate with plant roots to enhance nutrient uptake and soil life in the root zone, potentially helping plants establish more quickly after planting or transplanting. The product is ready to use, so you can mix it with the backfill soil to ensure the root zone receives immediate contact during installation.
