This is how to keep the roots in check

What is a root or rhizome barrier?

The job of one Root lock can be summarized in a few words: it should lock the roots in, i.e. prevent them from spreading. This is particularly recommended for tree and other plant species that multiply strongly via runners and do not have a root or branch. Rhizome barrier quickly overgrow the entire garden area. However, there are other reasons for the additional installation of such a root barrier, especially with extremely shallow-rooted trees:

• Tree roots lift paving stones and others Road surfaces at
• Their roots grow around supply lines and burst pipes are the result.
• The roots grow into drainage pipes, water pipes or sewers.
• Roots can destroy masonry foundations.

What material should a root barrier be made of?

Many gardeners use conventional pond liner, but we strongly advise against this. The flexible, thin material is not suitable for stopping strong tree roots and limiting their growth. Roofing felt also does not hold back trees that form runners. Instead, it is better to use special root barriers made of stable, high-density plastics, such as hard polyethylene (HDPE) or polypropylene (PP). These are available in roll form and can be cut to size to fit your needs. it is simply a matter of preventing a shallow-rooted tree from making cobblestones and others To raise pavement, it is best to dig lawn curbs along the path in the appropriate one Depth a.

How to build a root barrier

The installation of a root barrier, on the other hand, is quite straightforward:

• Lift that Planting hole generous.
• Leave enough space for the roots to spread.
• Otherwise it can happen that these first grow downwards and then spread.
• Depending on the tree species and root system, the root barrier should reach at least 60 centimeters deep.
• Cut off the required amount and lay out the root barrier in a ring.
• The two ends should overlap.
• An additional securing by means of a screwed-on aluminum rail is also useful.
