CONTROL BAGS -
Trees without a Tree Spade
Trees or shrubs are
planted into the Root Control bag. As the roots of the plant grow,
they hit the fuzzy inside fabric of the bag. Importantly, roots
do not circle on the fabric as they do against plastic. Instead,
the root is caught by the fuzzy inner surface of the material The
root penetrates the fabric. The tough fabric, however, presents
the root from expanding. The root is choked by the fabric, the root
tip looses its apical dominance and lateral root branching, or pruning,
occurs inside the bag.
Root pruning is important
to the health of a transplanted plant. A high quality plant saves
you money. With the Root Control bag, approximately 80% of the root
structure is harvested with the plant. By contrast, a recent study
at Michigan State University showed that up to 98% of a treešs root
structure can be cut away with normal digging procedures.
Water and nutrient absorption
occurs normally both inside and outside the bag at the root tips.
Water and nutrients are transferred up through the center of the
root, the xylem. Remember, the fabric bag is porous. Moisture and
nutrients pass freely into and out of the bag.
in the leaves travel down the outer cambium layer of the plant,
the phloem. This carbohydrate flow is stopped or greatly restricted
by the fabric. A build up of carbohydrates ensues within the root
system inside the bag. Many roots will swell on the inside and outside
of the bag and a natural callusing occurs at the bag surface. Root
primordia form with the callous, assuring rapid root regeneration
When the tree is transplanted,
REMOVE THE BAG. Water the plant. Because of the fibrous feeder root
development, the carbohydrate build up, and the root callusing,
new root regeneration is almost immediate. Expect a greatly expanded
harvesting season, superior transplanting success and top growth
the season following transplanting.
The bottom of the Root
Control Bag is polyethylene laminated onto polypropylene fabric.
This laminated plastic bottom assures that all root growth is lateral
through the fabric. All roots hitting the plastic bottom are diverted
into the fabric side. Easy digging is then assured. Because the
plastic bottom forms no attachment to the roots. bag removal is
The bottom of the Root
Control Bag is applied by a hot melt glue process. The glue process
leaves no sewn seam through which a root can escape. The superior
fabric, the glue process and the years of testing make the Root
Control Bag the best growing system available.
