Warning! Japanese perennial knotle threatens the Spree near Bautzen!

A paddle trip on the Spree near Bautzen led Bodo Thiemann, CDU city council and entrepreneur, to an alarming discovery: Visibly visible, vegetable material in the water, which was strongly reminiscent of freshly cut bamboo. It soon turned out that it was the Japanese perennial knotle, a plant that is considered to be invasive and can significantly disrupt the ecological balance. In a report by Sächsische.de It is mentioned that the State Tall Classification Administration (LTV) of the Free State of Saxony has confirmed the presence of this neophyten in the Spree.

originally came from East Asia, the Japanese perennial knotle was introduced to Europe as an ornamental plant in the 19th century. The tough perennial dweller grows quickly and is particularly difficult to combat because it strikes out of the smallest rhizome parts. Tree trunks that lie in the water also stove flotsam and create ideal conditions for the spread of the plant. "The banks of the bank are endangered by this plant, and domestic river vegetation is displaced," said Bodo Thiemann.

The challenges in combating

a? Complete control? According to the experts, the Japanese perennial knotle in Saxony is hardly possible. The LTV has measures to combat, which, however, take place only selectively and after individual examination. "We regularly check water sections, but we don't have a comprehensive distance strategy," explains a representative of the LTV. Thiemann pointed out the lower water authority to the contamination that could result from improper disposal of garden waste.

dr. Heiko Korsch, a botanist, indicates in an article by mdr.de Plant gives, but the cultivation is clearly advised. In Switzerland and Great Britain, planting and tolerance of this kind is even prohibited. In order to remove the knotle from gardens, patience and stubborn handling of the plant are necessary, Korsch recommends. If the roots are not completely removed, the plant grows quickly.

about the plant itself

The Fallopia Japonica perennial, as the Japanese perennial knotle is called botanical, can reach a height of up to four meters. Your strong rhizome can penetrate up to two meters deep into the ground and serves as a hibernation body. "The above-ground parts die at the first frost, but medals for the fastest growth are safe," explains mein-schoener-garten.de 30 centimeters a day.

is urgent. It is the responsibility of each individual to safely dispose of garden waste and not to burden nature with invasive species. If everyone makes a bit of effort, the spread of the perennial knotle could perhaps still be contained.
