They discovered hot spots of a Japanese whale in Dorset

NEW DATA has revealed the hotspots in Dorset with the “most invasive plant in the United Kingdom”, the Japanese Knotweed.

The invasive plant species is responsible for damaging homes, sidewalks and canals and can spread up to seven meters horizontally.

With the onset of the Japanese whale’s growing season, invasive plant specialist Environet UK has revealed spring horsetail hotspots using data from its online map.

There are currently almost 55,500 known cases of the most invasive plant in the United Kingdom.

The hotspots of the Japanese Knotweed in Dorset for 2022 are: Dorchester with 24 infections within a radius of 4 km, Poole (23), Weymouth (22), Bournemouth (21) and Swansea (18).

Knotweed overwinters in winter, but in March or April begins to grow, with red or purple spear-like shoots that emerge from the ground, which quickly grow into lush green shrubs with pink-spotted stems and bamboo canes.

For homeowners, the plant can create serious problems if left unchecked, with the potential to grow through cracks in concrete, paved alleys, paths, canals and cavity walls.

The roots can grow up to three meters and spread up to seven meters horizontally. Although serious property damage is rare due to regulations that require treatment of the notice, it usually affects the use of the garden, causes legal disputes between neighbors and can affect the value of the property by about five percent.

According to a study by Environet, approximately five percent of homes are currently affected by knotweed, directly or indirectly.

What to do if you think you have Japanese kintovid:

• Order a professional study of the Japanese whale to find out the extent of the infection, where it came from and the best way to deal with it.
• Organize a professional treatment, usually a herbicide or excavation, and always make sure you have an insurance guarantee for your work.
• If you are buying a property and you want to make sure that there is no note in it, especially if it is located in or near a hot spot, organize a survey of dogs for detection.
