Nurseries & Greenhouses Program

A biological program for nursery and greenhouse production that builds soil and media biology, improves nutrient uptake, and strengthens disease control.

What the Nurseries & Greenhouses Program Is

DPH Biologicals programs are designed to step up soil and plant health by increasing nutrient uptake, improving plant stress tolerance, and strengthening disease control and prevention. For nursery and greenhouse production, the program pairs microbial biofertilizers, a biostimulant, and biological fungicides to build living biology in container media and soils, support strong root development, and protect young plants through propagation and grow-out.

Who It Is For

The program fits container and field nursery stock, ornamental and flowering crops, foliage, and greenhouse production, anywhere a grower wants healthier media biology, better nutrient use, and stronger disease protection from propagation through finishing.
