Bamboo control

DeepRoot rhizome barrier has proven to be an effective material to prevent the unwanted spread of bamboo. The smooth surface of the rhizome barrier acts as a root stop, diverting the rhizome and preventing rampant growth. The rhizome will turn and continue to grow along the surface of the barrier. This helps contain the bamboo and aids in preventing the unwanted spread. The barrier is a thick plastic (HDPD) based material. As you may know already plastic is not biodegradable, therefore a thick plastic will last a very long time underground.

We have done studies with many other sources and found that the 30 mil or 0.76mm is great at diverting bamboo rhizomes. Why pay more for thicker plastic barrier when all it has to do is divert the rhizome. If a vendor has 40 or 60 mil barrier that is what they try to sell you. We stock 40 mil also, but I do not push it. We can stock any thickness we desire, but have found the 30 mil to be all you need to divert rhizome growth so why pay more.

BARRIER WORKS BEST AS A DIVERSION TYPE CONTROL METHOD WITH A
VERY SMOOTH SURFACE ON THE SIDE FACING YOUR BAMBOO PLANTING.

Plastic thinner than 30 mil has been shown to crack when ground temperatures 24 inches deep get below -15 degrees F.. This would be extremely cold and the 30 mil does great at handling very cold temps. without damage. Barrier an inch thick would not crack either, but why pay the cost when the results are the same. The plastic barrier will not crack when frozen like other materials, even concrete will freeze and crack over the years. I know you all have seen concrete driveways with cracks in them. Driveways are poured 4 to 6 inches deep to allow heavy vehicles passage and parking. Concrete was used many years ago ( Byron Agriculture Station in Byron, Georgia) as a below ground barrier system and found to crack below the frost line allowing bamboo rhizomes to emerge through to the other side. One of the many myths of bamboo is its ability to crack solid concrete. While a clumping type bamboo may do this, given enough years, a running type bamboo just runs and does not usually apply the outward pressure of a clumping bamboo or hardwood tree.

Bamboo is not magical, but persistent and its root system will eventually find cracks in concrete and emerge through them. If the environment ( sunlight & soil ) is suitable once it emerges the bamboo will grow if not terminated. The rhizome ( root ) when growing is very soft and flexible and will always turn when it encounters something harder. Furthermore, installation of a barrier will accelerate the grow of a bamboo screen. The growth will be more dense because of the confinements and stimulate the screening effect.

The 30 mil Polyethylene is 0.030" (0.76 mm) thick and has been made from recyclable sheet material.

Determine the extent of the area to be given over to the bamboo. Dig a trench around the entire area
and place the barrier inside.

1. Place the barrier into the trench with the shinny or glossy side toward the bamboo. Overlap the ends of the
barrier by 4 feet and apply a sealant tape vertically on inside and outside of planting area.

2. Place the top edge of the barrier approximately 1 inch above the finish grade. This will deter
overgrowth and make annual maintenance easier.

            Plant according to the standard bamboo nursery planting directions paying attention to soil
            deficiencies, drainage and compacting. Be sure the planting area still drains well or the root
            system will rot.

            Annual maintenance is a key to controlling bamboo even with a root barrier.
            Rhizomes spread outward from the center of the plant in late spring, summer and fall. Each December when
            rhizome activity has ended clear the top edge of the barrier and inspect for any rhizome over-growth. If any
            rhizomes have gone over the top of the barrier cut them off and pull them out of the ground. If this procedure
            is done annually the rhizome are new, soft and easy to remove.

Rhizome barrier is sold by the linear foot.
Barrier can be up to 300 feet uncut, if less is purchased then it has to be in increments of 25 feet.

We do not cut to odd lengths, so the barrier must in lengths of 25 feet, 50, 75, 100, 125, 150, 175 and so on to 300 feet uncut.

We stock the 24 wide 30 mil barrier in large quantities.

We stock limited quantities of the 30 inch wide barrier in the 30 mil thickness.

We stock the 40 mil in 24 inch widths for those wanting extra thickness.

Sealant tape is provided free with any barrier order, but you do need to request it.
