Landscaping & Turf

Green Diamond Biologicals & Nutritionals is an RTI brand built specifically for the landscape and turf professional market. Based in Gilroy, California, the company applies the same deep mycorrhizal fungi expertise that underpins RTI's forestry and agricultural divisions — but tailors its products for the unique demands of commercial landscapers, golf course superintendents, restoration contractors, and grounds maintenance crews. The guiding principle is straightforward: healthy, biologically active soil reduces long-term maintenance costs, improves plant establishment, and produces more resilient landscapes over time.

The product line is split across two main technologies. The Landscape PRO line packages fertilizers into biodegradable paks — essentially a tea bag format designed to be placed directly in the planting hole at transplant. These come in formulations tuned for different plant types, including a 20-10-5 feeder pak for general landscape plantings, a 10-2-4 tree pak for larger specimens, and a 7-2-4 palm pak for the specific nutritional needs of palm establishment. Alongside the pak products sits the MYKOS PRO line, a granular mycorrhizal inoculum available in both straight biological and fertilizer-blended versions, suited to applications like golf greens, turf renovation, large flower beds, and container plantings where a broadcast or root-zone application is more practical than an individual pak.

The economic case Green Diamond makes to landscape professionals is grounded in total cost of ownership rather than just product price. By improving root colonization and soil structure from the moment of transplant, the mycorrhizal products are positioned to reduce water usage, lower the frequency of fertilizer applications, and boost establishment success rates — all of which translate directly into labor and input savings across large-scale projects.
