Trees are a costly and
major part of your landscape. Trees provide shade, privacy, and
beauty but a tree in the wrong place can become an expensive problem
in years to come.
The ultimate size and shape of the mature tree,
how much annual maintenance it will require, the location in your
yard, and the purpose you intend are among the many considerations
when selecting a tree.
Many species with a wide variety of characteristics
are suitable for our area. |

1) Biobarriers
are made of a durable, nonwoven, polypropylene geotextile fabric
with permanently
attached nodules containing trifluralin.
Trifluralin prevents root tip cells from dividing, which is the
method by which roots grow. The nodules are engineered to slowly
release the trifluralin, creating a zone where root growth is
inhibited. The geotextile fabric is porous to allow air, nutrients
and water through it so that soil hydrology can continue to be
healthy.
Characteristics:
For more than 30 years, trifluralin has been used between rows
of food crops to prevent weed growth; because of this extensive
use and numerous research projects, much is known about it.
It has an EPA toxicity rating of class IV, the “practically
nontoxic” class (acute oral: LD50, (rats) > 10,000
mg/kg), making it slightly more toxic than sugar but less
than salt. Trifluralin has an extremely low water solubility
of 0.3 ppm, making it unlikely to leach. It tightly attaches
to soil, so it doesn’t tend to migrate, and it decomposes
in six months or less, so it doesn’t persist in the
ground.
2) Biobarrier Root Control System prevents tree roots from
growing in a zone around the fabric. Placed between a tree
root and the area to be protected, such as a sidewalk, road,
building, golf course green or anywhere that roots can cause
damage, Biobarrier creates a barrier that causes roots to
grow in another direction. Unlike solid barriers, it does
not need to protrude above ground where it could be a tripping
hazard and costly liability. Because it is a flexible geotextile
fabric.
