Rootmaker

RootMaker® Products Company, LLC. was formed to be the exclusive manufacturing and marketing organization for the Whitcomb System® of commercial plant production products developed by Carl Whitcomb, Ph.D. — a leading authority in commercial plant production and horticultural research.

At RootMaker®, we are dedicated to creating fibrous root systems. Our products are designed to promote root branching at every phase of production.  The result is the ultimate fibrous root system. A more fibrous root system means a greater surface area and translates to greater efficiency in the absorption of water and nutrients; an increase in growth rate, establishment, and vigor; a higher transplant survivability; and ultimately, superior performance for the gardener.

RootMaker® containers are designed to direct roots toward an opening in the container. The first root to reach an opening is usually the tap root. Once the tap root reaches one of the bottom openings, the tip dehydrates and stops growing. When this occurs, secondary roots that are more horizontal in growth habit will form. These secondary roots soon reach the side openings, dehydrate the root tips, create tertiary branching, and so on, until the entire container is filled with very efficient feeder roots.
