Uni-Gro Vermiculite Soil Additive

Uni-Gro Vermiculite is a lightweight mineral additive used to increase moisture and nutrient-holding capacity in growing media. Its expanded particles can be blended with other components to balance water retention and pore space for seed starting, propagation, and container mixes.

Blend at the rate appropriate for the crop and application. Because plant requirements differ, test the finished medium’s drainage and moisture retention rather than assuming one blend suits every plant. Handle and store according to the package directions. Browse related soil amendments .

Use the specifications above to decide whether this material belongs in a seed-starting mix, container blend, or garden-soil amendment. Test a small batch before changing a familiar mix.
