RootMaker's root pruning containers create fibrous root systems using Air (RootMaker®, RootBuilder® plastic pots), Constriction (Knit fabric tree bags), or Trapping (RootTrapper®) from propagation to large trees. Our products are designed to promote root branching and new roots at every phase of nursery production, whether above-ground, in-ground, or even ­in-pot. This results in a root system that has a greater surface area than conventional production, and therefore achieves greater efficiency in the absorption of water and nutrients, an increase in growth rate, establishment, transplant survivability, and ultimately, superior performance for your customers.

RootTrapper II Soft Sided Containers

The RootTrapper® is an attractive container that benefits your plants. Our RootTrapper® Container is a white, soft-sided container that stimulates root branching by trapping root tips. Because the container is white, the soil temperature is reduced, which leads to greater root growth and less water usage.

RootMaker II Propagation Containers

The first step toward creating a fibrous root system is RootMaker® Propagation containers. These containers give vegetables, flowers, shrubs and trees a good start by creating more root tips. An increased number of active root tips means a healthier, more efficient plant.

RootMaker II - Injection Molded Containers

RootMakers® are designed to create fibrous, non-circling root systems horizontally and vertically at all phases of production to equip plants for transplanting success. Our products aren't just "containers" but rather root production tools. Each step complements the next, building upon the previous fibrous root system. A fibrous root system means a greater root tip surface area and translates to a 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.

RootBuilder II Kits

These containers are easily assembled around a bottom disk. A hole is at the tip of each outwardly projecting funnel on the side wall of these two containers. Roots are directed outward toward these holes, forcing them to branch and continuing the air root-pruning process.


RootmakerII® is the latest and greatest design by Dr. Carl Whitcomb. These containers create a fibrous, non-circulating root system that promotes horizontal root branching.


There are many ways to propagate plants for indoor gardening and we have the products to help you be successful. Need some advice on propagation techniques? Ask us what we know. We know a lot about propagation.
