All other containers are just packaging. RootMakers are tools.
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.
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.
