Invasive Species

For an increasing number of homeowners, businesses and landowners, invasive species such as Japanese Knotweed are causing a significant, and costly, problem to eradicate.

What are Invasive Species?

Reported instances of invasive species have risen all over Europe. Some species do so well in their new environment that they can proliferate and damage local biological diversity or cultural environments, and in the worst case displace indigenous plants.

Many of these species are on the EU's blacklist, and strategies are being drawn up for controlling them in Europe.

The list of problematic species includes well-known plants like Giant Hogweed, Persian Hogweed, Himalayan Balsam, Japanese Knotweed, Policeman’s Helmet, Crassula Helmsii (New Zealand pigmyweed), and Lupins, all of which are now common in the UK.

Awareness of the problems caused by outbreaks of invasive species such as Japanese Knotweed has been improved by the vast media coverage over recent years. There have been a huge number of homeowners left facing vast sums to deal with Japanese Knotwood invasions, and ramifications from mortgage lenders being unwilling to provide lending on an affected property.

Treating Japanese Knotweed and Other Species

Traditional treatment of Japanese Knotweed can be a hugely expensive exercise, with no guarantee that it will be effective in the long-term. Indeed, recent tests have shown that Japanese Knotweed can still rejuvenate after 18 years.

As the testing of Japanese Knotweed continues, new data is becoming available all the time, which has now resulted in the finding of female plants. Previously, only male plants had been documented so this is potentially a significant problem for areas prone to invasion as they will be able to reproduce from seed.

Typical applications for our invasive weed control service are:
  • Schools and playgrounds- chemical free, cost effective weed and invasive species control with no health risks.
  • Train stations and railway tracksides – removing weeds, algae and moss at stations and more harmful invasive species in isolated trackside locations.
  • Gardens – residential clients needing a cost-effective solution to Japanese Knotweed as well as commercial grounds and gardens.
  • Waterways, harbours and marinas - the growth of algae is a recurring problem. Our hot water system keeps the area algae, moss and weed free year after year, without the harmful effects of chemical treatment and far more cost-effectively than manual removal.
  • Commercial and industrial premises – effective treatment and control of sites, no matter how small or large.
  • Parks and nature trusts – Eco Weed’s hot water system works perfectly in any park. In addition to the paths and gravelled roads, our method can also be used with success in flower beds, in hedges, around trees and other plantings. They key is the extremely low pressure and water consumption along with being chemical free.
ecoweed Japanese Knotwood Control

Eco Weed’s specialist hot water treatment method means that we can control and manage even the most stubborn invasive species, stopping plants from spreading and minimising the effects.

Although a guarantee of full eradication cannot be provided, using Eco Weed’s unrivalled Japanese Knotwood removal service will ensure that problems areas are appropriately, and cost-effectively, managed.

Typically, an initially treatment reduces even the most stubborn and problem outbreaks of Japanese Knotweed and Giant Hogweed by up to 30%. Our regular quite and efficient follow up treatment then further reduce masses, resulting in contained area of around 10% of the original invasion. This can then be managed and evidencing the reduction will ensure that mortgage providers are satisfied and the other threats posed are mitigated.

Giant Hogweed (Heracleum mantegazzianum)

Although this is an impressive looking plant when fully grown, it is a non native invasive plant which forms dense strands reducing species diversity, each plant has he ability to produce 20,000 seeds!.

The plant also produces a phytotoxic sap which combined with UV radiation causes skin burns.

ecoweed hot water treatment is an environmentally friendly and sustainable way to treat and reduce the species, ecoweed can achieve a 90% reduction in year 1 of treatment, ideal treatment start time early Spring, a 3 year treatment program is recommended and careful monitoring to deplete the seed bank for up to 7 years, small seedlings are leaf treated  above ground larger mature plants are root treated and leaf treated, which also reduces the health risks as the hot water renders the sap safe.
