About the RPM Method
The Root Production Method (RPM) is a natural process found to positively affect trees, shrubs, and grasses, resulting in accelerated growth, increased root mass, early flower, fruit, seed, and/or nut production, and higher rates of establishment and survivability.
RPM is composed of a series of horticultural practices including: collection of superior native seed stock, air-root pruning, greenhouse growing, acclimating to local conditions, balanced nutrition, soil microbial and fungal relationships, container growing in special media, and timing learned from over 20 years of field research.
