These prevent an inflationary spread of bamboo, the rhizomes often do not form directly after the first planting, but it may take several years until they are noticed. The foothills can occur several meters next to the mother plant. Bamboo grows even where there are stones or even beyond their own property boundaries. Therefore, a propagation of the bamboo in advance can be prevented by the onset of rhizome barriers. For this purpose, a ring made of polyethylene, so made of plastic around the plant or the roots of the plant is brought into the earth. Care should be taken that the film has a thickness of at least 2 mm.
Bamboo vs. Japanese knotweedThe Japanese Knotweed resembles bamboo. It also spreads through the rhizomes in the garden and has similar stems. However, the knotweed dies on the surface in autumn, while the rhizomes can overwinter. The knotweed, however, has a different leaf shape than the bamboo. The Knotweed has in contrast to the bamboo, which has elongated leaves, ovate and broad leaves. It should be noted that these rhizomes can protrude up to three meters in depth. If the removal of the bamboo proves that the roots go very deep, it may be Knotweed.
Ways to remove bamboo rootsThe bamboo is a very tough and stubborn plant whose rhizomes are very difficult to remove. However, there are both manual and biological and chemical ways of tackling the bamboo roots. However, this is usually associated with a lot of work and patience.
1. The manual removal of the bamboo from the gardenTo completely remove bamboo from the garden, all parts of the roots must be removed. If only a small piece of it remains, a new bamboo will develop, which will once again be inflationary. If the bamboo has spread out of its own stock, it is important to introduce a root barrier in hindsight, limiting the spread to the area where the bamboo is allowed to grow. The subsequent insertion of a rhizome barrier is very cumbersome, because this bamboo must be excavated with the full rhizomes, then to introduce the root barrier. Only then will the bamboo be planted again. The unwanted roots around it now have to be dug out by hand.
Often this is complicated by other plants, which can not fully excavate the roots. It makes sense, therefore, to dig out all those plants that are to be preserved. Following this, the earth is dug deep and thoroughly. It may be necessary to add new soil. Only then can the previously removed plants be reset. It is important that the bamboo roots are not placed in the garden compost, as they can spread out from here.
2. The covering of garden sectionsWhen rhizomes spread in an unplanted part of the garden, there are several ways to remove them:
- On the one hand, the bamboo roots can be excavated here as well.
- On the other hand, there is the possibility of occupying parts of the garden with paper, cardboard or newspapers.
3. Combat the bamboo with chemical agentsIn addition to natural or manual methods, chemical weed killers can also be used. However, the use of herbicides is not very environmentally friendly and plants that are not to be destroyed can also be affected. The funds must usually be applied several times, since a single application is not sufficient to completely remove the roots of the bamboo. However, before the shoots can be treated with a weed killer, all visible bamboo parts that are above the ground must be removed. For this one starts usually with the leaves and removes the stems of the bamboo. Only then, if only the tender shoots are present, the plants are sprayed with the agent.To be able to remove the roots definitively, however, this treatment must be repeated several times without any real claim to success, since bamboo is a very powerful plant, even under adverse circumstances.
Bamboo roots can be removed by several methods. The manual methods are more effective than the chemical clubs, but they are very time consuming and labor intensive. In all cases, work must be done very thoroughly, as otherwise the rhizomes will find a way to re-expel stems and leaves.
Tips for removing bamboo roots soonIf you have failed to set a root barrier while planting the bamboo, you will need to free the areas where the bamboo is not wanted from its root shoots. Bamboo roots spread in all directions, so the entire area around a plant needs to be worked to keep the bamboo from growing.
- Since the foothills form to a depth of 60 cm, the soil must be excavated to this depth to expose the foothills.
- In a single plant, this can be done by hand with a spade, otherwise a small excavator would be recommended.
- After the foothills have been exposed, they can be tapped and destroyed with a spade.
- If the bamboo is completely removed from the garden, it is important to destroy all foothills, otherwise the plant could later expel again.
- The excavated roots should not land on the compost heap, because they could drive out and recharge.
- So that the unrestrained spread of the bamboo roots does not start all over again, a root barrier can be installed around the plant.
- This is a plastic film, which is placed edgewise around the plant in the ground and can not be penetrated by the bamboo roots.
- This rhizome barrier is best closed at the joints with an aluminum rail, so that even at this point no roots can penetrate into other areas of the garden.
- It should have a height of at least 60 cm and protrude a little way out of the ground to protect the area just below the surface of the earth.
- This outstanding piece can later be covered with some earth or mulch layer.
In order not to be able to fight the roots of the bamboo later with much effort or to set a root barrier, there are also some bamboo species in which this problem does not occur. The varieties of the Fargesia do not form subterranean foothills, while the biggest problems with the bamboo roots usually arise in the different species of the Phyllostachys.
