Install rhizome barrier - That's how it's done

The Content Of The Article:

Bamboo, blackberries and Co. look nice, but can be a real nuisance. For example, if they proliferate too much. A rhizome barrier can help but there.


There are some plants that grow so badly that they quickly overgrow everything else. These include, for example, raspberries, blackberries, miscanthus, ivy, mint, black and sea buckthorn, vinegar, bamboo, lily of the valley or horsetail. If you do not intervene early and keep the plants in check, then this not only means that your garden looks very wild at some point, the plants just mentioned can also make the living space of other plants in dispute.

So that the strongly proliferating plants do not spoil the mood and make unnecessary work, it is advisable to install a rhizome barrier (also called root barrier). This is not even so difficult with the appropriate equipment and can even be retrofitted in the garden.

You need this for the installation

When it comes to the installation of a rhizome barrier, you must always take into account the peculiarities of each plant in the implementation. Some plants, such as the bamboo, form extremely strong rhizomes. In this case, you must also build in an extremely strong root barrier so that you can actually stop the rhizome.

In such a case, it is also best to use a rhizome barrier made of HDPE (high pressure polyethylene) that is at least two millimeters thick, as it can not be pierced by the roots of the plant (for example, available here). An alternative to this plastic could be at most concrete slabs, but the installation is in this case, of course, a lot harder. So it's best to go back to HDPE. On materials such as e.g. a sturdy pond liner, you should do without, because it would not last in the long run.

So a root barrier is installed

It is important that the barrier is as deep as possible in the soil so that the roots can not grow underneath. Therefore, a depth of about 60 cm is recommended. However, it is equally important that you leave enough room for the plant in the width, otherwise the foothills grow more in depth and then eventually come through under the root barrier. Now that you know that, proceed as follows:

➥ Step 1:

root barrier

Lift the hole for the plant 60 cm deep and then take the root barrier to the hand.

➥ Step 2:

Connect the two ends of the rhizome barrier with the supplied aluminum rail so that a ring is formed that has no gaps.

➥ Step 3:

Insert the rhizome barrier vertically into the trench and make sure that it is 5 to 10 cm thick. This way, no root extensions can spread on top.

➥ Step 4:

Then fill the interstices with the excavated soil and insert the plant into the ring. Make sure that you do not plant the plant flush with the top of the rhizome barrier, but about 10 cm deeper.

Install root barrier later

Sometimes you place plants in the garden and at the moment you do not think about installing a root barrier. Of course, you can then install the lock later. However, this is associated with much more effort.

➥ Step 1:

First of all you have to cut off all already existing root shoots with a spade.

➥ Step 2:

After cutting it around the plant dig out a trench to insert the barrier there.

➥ Step 3:

Then carefully connect the two ends of the rhizome barrier and then fill the soil back into the ditch.
