Root System Basics

Slideshow presentation narrated by Dr. Whitcomb

Why RootMakers?

All other containers are just packaging. RootMakers are tools.

Propagation...

The first step to creating a fibrous root system is with

RootMaker® air-root-pruning propagation trays. 

to Specimen Landscape Trees...

With the expandable RootBuilder® air root root pruning containers and RootTrappers ®  to 100 gallons, roots can continue to improve through all steps of large tree production.

and Everything in Between

Following propagation, there are options to best fit your nursery production , with injection-molded, in-field, or water-conserving soft-sided RootTrappers ® .

Air Root Pruning

Constriction Pruning

RootMakers® are designed to direct roots into openings

in the container. The first root to reach an opening is

usually the tap root. When this occurs, the tip dehydrates

and stops growing and secondary roots form that are

horizontal in growth habit. These secondary roots are

dehydrated and create additional root branching.

The Knit Fabric container offers the ability of growing in

the field with the ease of harvest and mobility of containers.

With openings 5/64th inch in diameter, root pruning

is predictable and precise. Root constriction occurs at

the proper root diameter in order to stimulate secondary

root-branching. As a root increases in size, both inside

and outside the fabric wall, a callus bridge will form at

the adjacent opening in the fabric. When the plant is

harvested, the roots break off at the face of the fabric.

This callus bridge prevents stunting of tree growth.

Root Tip Trapping

The RootTrapper® container is a black, spun-bonded

fabric, laminated with a white outer coating. The inner

fabric stops circling roots and continues to stimulate root

branching by trapping root tips. The white outer coating

greatly reduces container temperature so roots do not die

on the sunny side as with black plastic containers.
