Japanese knotweed Identification
If you suspect a plant is Japanese knotweed, then it is essential to act quickly to identify the weed. While Japanese knotweed is not poisonous, it has the potential to cause significant damage to homes and costly delays on construction projects.
What does Japanese knotweed look like? Once you know what you are looking for with Japanese knotweed, it is usually easy to detect. However, if you’ve never had experience with the invasive species, then it can be tricky to identify as it can take on different characteristics throughout the year.
Key characteristics of knotweed include ...
• Stems that look like asparagus spears in spring
• Tall, green and purple canes reaching up to 3m high in summer
• Clusters of small white flowers in late summer
• Brown, bamboo like brittle canes in the winter.

The problem with Japanese knotweed
Japanese knotweed is an incredibly invasive and powerful species that can cause damage to your building, underground services and driveways. The weed can quickly out-compete any of the native vegetation and takes advantage of weaknesses in walls, foundations and underground services. If left untreated, Japanese knotweed can develop an advanced root network that infiltrates the structure of buildings and can spread to adjoining properties.
Japanese knotweed can be so damaging that many financial institutions will not approve mortgages for properties where there is a known history of knotweed. If the provider does offer a mortgage, it will be on the basis that the property has an effective Japanese knotweed treatment plan in place with a 10-year insurance backed guarantee from Japanese knotweed specialists such as Environet.
If you detect Japanese knotweed on your premises, call Environet, the Japanese knotweed specialists to come and treat and eradicate the weed. Tackling it yourself is not recommended as this can lead to the spread of the weed. Without treatment, Japanese knotweed will continue to grow and spread. Furthermore, if the knotweed spreads into neighbouring gardens, then you may face legal action with a civil claim in private nuisance.

Japanese Knotweed Removal
As Japanese knotweed specialists, we begin the removal process by carefully assessing each site, its constraints and the client’s circumstances. From then on, we engineer tailored solutions. As each site has its own requirements, we work on a case by case basis. Some of our revolutionary techniques for Japanese knotweed removal include Eco-Innovative Xtract™ which is a soil excavation and screening technique to remove rhizome. This method does not use herbicides, is cheaper than traditional methods and is ideal for commercial Japanese knotweed removal.
One of the most effective residential treatments ...that our Japanese knotweed specialists offer is DART™ which is a unique Japanese knotweed removal method. This is ideal where previous herbicide treatment has failed and access for full excavation is limited. Another method we offer is Resi-Dig-Out™. This is ideal for residential properties and uses a similar technique to Xtract™. The Japanese knotweed is removed via physical excavation, the rhizome is separated, and removed from site, allowing the soil to be left on site.
For the best results, it is wise to consult Japanese knotweed specialists who will advise on the approach that meets your requirements and timescales. The most effective way to remove Japanese knotweed is to select the right method for the conditions on site, with subsequent site monitoring to ensure the whole plant, roots and rhizome are eradicated for good. At Environet we offer a range of different options for Japanese knotweed removal; from herbicide application to site supervision if you want to provide your own machinery. Whatever your need, Environet offers a bespoke service fully tailored to your needs.
