Bamboo Root Barrier Depth

The roots are very thin the actual rhizomes on the other hand don t go that deep.

Bamboo root barrier depth.

The american bamboo socia in hard clay soil some say it is okay to use only a 24 inch 61 0 cm wide barrier. For example if you are installing a 24 barrier dig a 22 trench. These are the basics of how to use this product when using it to install bamboo. Bamboo becomes more aggressive in warmer climates.

The root systems on clumping bamboos is usually only about 300 to 400mm deep so this 600mm root barrier is typically installed to a depth of 500mm in the ground leaving 100mm sticking out of the ground. The polyethylene barrier is made from post industrial recycled regrind material when possible in the usa. To stop the natural spread of the bamboo clumps root barrier can be installed to stop any roots and rhizomes from growing into unwanted areas. For areas where the soil is sandy and loose a 36 inch 91 4 cm wide barrier may be required.

Bi annual root pruning around the edge of a running bamboo is the most effective way to achieve long term control. Bamboo roots typically travel in the first 12 inches of topsoil. Barriers are sold in 24 30 and 36 depth. The trench should be 2 less deep than the depth of the barrier that is to be installed.

Barrier are sold in 24 30 and 36 depths to provide extra protection from stray growth. That s because when you install the barrier the roots will run downward in an attempt to go around the barrier. In other words if the bamboo plant s roots extend into the ground 18 inches you should choose a 30 inch barrier. Even though the roots will more than likely head upward there s still a chance they will head further underground.

Place the barrier in the trench. Once the depth of the roots is determined it is recommended that a barrier is chosen that is approximately 12 deeper than the depth of the bamboo roots. Determine the extent of the area to be given over to the bamboo. Fortunately rhizomes are usually very shallow rooted and prefer to grow in loose topsoil 2 5 inches beneath the surface.

Dig a trench around the area where you are planning to plant the bamboo or where the bamboo is already planted. For additional protection or more aggressive species a 36 deep bamboo barrier is the best choice. For best results use a true hdpe high density polyethylene barrier of at least 60 mil thickness. So bamboo roots grow about 2 3 feet deep.

However a 30 wide barrier is safer. For example if the bamboo plant s roots extend 18 into the ground a 30 barrier should be chosen. Therefore we recommend deeper and thicker material as climate zone increases to provide antiquate protection from stray growth. By allowing an extra 12 inches in depth will provide a greater protection against the roots going under the barrier.

This will make it fairly easy to either get rid of the bamboo or to control it with a shallow barrier.
