Bamboo sprawls all over the garden - what to do?
The All-Rounder Bamboo
Bamboo are elegant plants that look good not only in Japanese-designed gardens. In local latitudes, bamboo plants are considered to be a constant all-rounder, which does not matter much to wind and weather. That is why many gardeners prefer the easy-care plant as a visual screen. However, the Asian giant grass is extremely growth-friendly.
Exactly this can be a plague, because its roots spread quickly and widely over the whole garden. Once planted it grows and grows and proliferates where there is no bamboo grass. Many bamboo species have the capacity to spread through subterranean shallow rhizomes (rhizomes) up to three meters a year. Normally these grow just below the surface, but varieties such as the Phyllostachya grow to a meter deep.
They overcome any obstacle and damage masonry and foundations under terraces and houses. This is a reluctant side-effect in home gardens, the otherwise versatile shrub. Once the grass has spread, its growth can no longer be contained. Bamboo rhizomes are so resilient that they are difficult to cut through with a spade and prevent it from growing.
Barriers protect the entire garden
So that bamboo does not overgrow the entire garden, every single rhizome must be separated, otherwise new spurs will form. Unfortunately, this control is extremely time consuming and can turn the garden area into a battlefield within a short time. However, the bamboo plant can stop a so-called rhizome barrier. For this purpose, a barrier made of HDPE (high-pressure polyethylene) has proven to be helpful.
Simply screw the beginning and end of the 70-centimeter-wide film to a round aluminum rail to form a ring. This closed ring is to dig in vertically, with five centimeters still look out of the ground. This edge prevents the rhizomes from breaking out. Although this method is one of the safest rhizome barriers, but expensive and labor-intensive when mooring.
Less costly and cheaper it is to plant the bamboo plant in a large mortar tub with humus and nutrient-rich soil. For the drainage, the soil can be easily cut out with a jigsaw. Then the bamboo bucket is also to sink to five centimeters edge overhang in the ground. The edge of the bucket can be wonderfully hidden under ground covers, gravel or ornamental grasses.
This variety of bamboo does not proliferate
Hobby gardeners often underestimate the formation of runners on bamboo. Suddenly they realize that this spreads over the entire garden. Therefore, a root barrier is essential. In addition, the project is costly and associated with high costs. Those who want to save themselves, can fall back on the variety Fargesia.
Unlike other bamboo, these do not form long Wurzelausläufer, but have a horstiges growth. That is, new stalks grow out of the plant in a circle. So the bamboo owner can be sure that he finds no new shoots in unwanted places. Therefore, it is possible to plant these species without rooting.
Of course, nothing speaks against the planting of flat-bamboo. Only the garden owner must take care that this does not proliferate all over his garden. Therefore, it makes sense to schedule a barrier before planting, which makes the project however costly. But it is worth considering choosing a screen bamboo (Fargesia), which can easily be kept in check.
