Solution to invasive bamboo
By far, the best technique to prevent bamboo from becoming invasive is to put in place an anti-rhizome barrier as soon as it is planted.
This plastic, concrete, wood or metal barrier will have to sink in at least 60-70 cm in the ground and protrude 10 cm above the level of the ground.
Be careful, if you use wood or metal, it is quite possible that over time matter eventually disintegrates and that the solution no longer works.
The method we recommend is then thepurchase of an anti rhizome barrier sold by the roll, and measuring 0.3 to 0.8 cm thick.
- It is then enough to dig a hole of 60 cm deep
- Arrange the barrier around, fill with soil and plant your bamboos.
- Take care that the junction of the roll leaves no light and, for this, tape the 2 parts well together.
- The bamboos will revolve around the film, rise to the surface and remain within the barrier set up
The rhizomes generally do not descend beyond 40 cm in depth but, as a precaution, the depth of 60 cm is recommended to avoid any unpleasant surprises.
