Bamboo is a decent plant, but it can dispute the habitat of other plants. To prevent this from happening, it makes sense to install a root barrier in the soil.
Bamboo is increasingly popular in our latitudes and is often planted in many gardens. Above all, because he is very tall and very dense, he is great as a visual screen. But the bamboo can also be a problem. Namely when he gets too big and hardens other plants. This does not mean the plant itself, but its roots. These can appear several meters away from the mother plant. Besides, they stop at nothing. Neither in front of stone slabs, pond liner, drainage or neighboring property. So you should take necessary measures while planting.
How can you keep bamboo in check?
In order to keep the root shoots in the fence from the beginning, you should already install a root barrier in the soil when planting. This can for example consist of concrete or stones. But you can also fall back on a root barrier from the gardening market. It is introduced as a ring about 70 centimeters deep around the plant and limits the subterranean growth of the bamboo. This prevents the roots from spreading.
Such a root barrier is made of high-pressure polyethylene, which can not be pierced by the roots of the plant. Such a root barrier is available eg at Amazon .
How to install the root barrier
- Raise the planting hole for the bamboo about 60 centimeters deep.
- Now take the root barrier and connect the two ends of the root barrier with the supplied aluminum rail.
- Insert the barrier into the ground. It would now have to survive about 10 inches. That’s a good thing, because that’s not how roots can spread over the surface.
Erde Now fill soil around the root barrier so that it sits firmly in the ground. Then plant the bamboo in the middle of the root barrier.
Separate roots with spades
If you have already set up the bamboo in the garden and no barrier, you can also use a spade. To do this circularly, the size you like, around the plant and cut out as deep as possible. As a result, the Wurzelausläufer be severed. That’s enough to keep the bamboo in check. However, you must repeat this procedure several times a year.
Root barrier can also be installed later
But you can also install a root barrier later. First, cut the root, then dig out a ditch around the plant and insert the root barrier. Then fill everything with soil again and the problem should be solved.
If the root barrier is planted, you can plant plants around the bamboo, without fear that the bamboo will deny them the habitat. Which plants are compatible with bamboo can be found in our article Which plants are suitable for bamboo?
