Green Diamond Biologicals & Nutritionals represents a true breakthrough in turf and landscape growth and maintenance. Our proprietary blends of mycorrhizae and nitrogen-fixing bacteria promote healthy root systems and plant durability. Turf and landscape plants grown with Green Diamond’s products need less water and, unlike conventional synthetic treatments and fertilizers, have nearly zero adverse effects on the environment. 

Benefits of Mycorrhizae


  • Promotes more vigorous plant growth and nutrient absorption by increasing the root surface.

  • Helps plants work more efficiently at accessing nutrients and absorbing water.

  • Inoculation results in significant water savings as less irrigation is required.

  • Greatly reduces transplant shock and improves plant establishment rates.

  • Reduces the need for pesticides and fungicides by providing a natural barrier against the entry of damaging pathogens.
