Bamboo has many advantages: it grows quickly and its soft green foliage is persistent. But it has a major disadvantage: it can be invasive. Before planting it, care must be taken to contain its roots.
If a high-walled wall creates a good breeze while preserving privacy in the garden, it sometimes forms a "wall" that is not pleasant to the eye. One of the solutions is then to dress a hedge plant along its length.
Choosing bamboos at the right height
The hedge here is composed of laurels, yews, aucubas and two feet of bamboo. To avoid that they grow too high, it is an average variety that has been chosen. Depending on its category, an adult bamboo can reach several heights: a dwarf less than 1.5 m, a small between 1.5 and 3 m and beyond, it is medium bamboo, even giant. These bamboos require a sunny exposure, a light soil and ask to be watered often enough. They plant all year, but never in freezing weather or strong heat.
Bamboo: decorative, but invasive
There are tracing bamboos and non-tracers. The first are the most common. After planting, their roots form clumps of rhizomes that divide and their underground stems run horizontally to sometimes stand out in the middle of the field or at the neighbor's. Less invasive non-tracing bamboo are also smaller. They grow less quickly and their foliage is less garni. Bamboo can be cut, but you should know that once cut, the cane does not grow back.
Where to find bamboo?
The bamboos are packed in jars in garden centers. But you can also get a foot (for example from a friend) a bamboo hedge already well-stocked to plant at home. For this, cut the roots and ramifications (far enough) to the ax all around the foot, then lift it with a pick. We must also be careful to collect leafy stems carrying rhizomes at the base. The plantation then poses no particular problem, provided the roots are contained
- To prevent rhizomes from spreading to the neighbor, start by digging a hole 60 cm deep at the foot of the separation wall.
- Install a special membrane.
- Thick, it prevents the pushing of horizontal roots.
- 70 cm high, it is sold for about € 7.50 per meter and is cut with shears.
- Plaster the membrane at the bottom of the hole and against the walls.
- Keep it at the base with soil: it is indeed quite difficult to handle.
- Unify the ground with a trowel and then have a bottom cover, letting its sides rise against the walls of the membrane.
- It will block the development of vertical roots.
- Fill the bottom of the hole with some slightly acid earth.
- The earth thus holds the first sheet of the membrane while waiting for its extension.
- Lay the vertical membrane in line with the first one with a 20 cm overlap.
- Secure the two sheets with galvanized wire tied to the clip.
- Thoroughly water the bamboo feet and place them inside the "antirhizome" belt.
- Finish filling the earth.
- The membrane should protrude by about 10 cm.

Tips from handymen
- If you want to create a screen of bamboo in front of a fence, make a base of buried blocks of 30 cm. They will serve to seal the poles of the fence, but also to barrier rhizomes.
- When planting bamboo, the thick plastic membrane that surrounds the hole should protrude about 6 cm from the ground level to form a water retention basin.
