japanese knotweed eradication
Green Estate Landscapes have long been experts in Japanese Knotweed removal and we are happy to continue this along with surveying, treatment plans and site clearance of Knotweed and other invasive plants. Japanese Knotweed is the most invasive and destructive plant in the UK. The root systems are extremely hard to remove as they can grow up to 3m in depth and 7m in all other directions
At Green Estate Landscapes we understand that the presence of Japanese Knotweed can be a cause for concern. As experts in Japanese Knotweed removal we will do everything we can to make the process as simple and easy as possible for you.

If you suspect you have Japanese Knotweed do not hesitate to contact us. You can send us photographs to help with identification before we come to your site.

After we have conducted a survey of your area we will provide a comprehensive written report. This will highlight our findings and will include a quote for eradication if Japanese Knotweed is found. We will also include tailored advice to help you in preventing its return.

Prior to treatment commencing we will provide signage and fencing where feasible to prevent contamination. To eradicate the Japanese Knotweed we will use a Glyphosate herbicide treatment. We use the environment agency recommended steam injection method. This minimises risk to other plants and is non-toxic to children and pets.

Following the injection of the glyphosate, we will monitor the progress of the eradication, including a follow-up site visit. Should further treatment be required this will be scheduled in order to achieve total eradication.

In most cases, we other a 10 year guarantee for piece of mind that if the Japanese Knotweed does come back, we will return to remove it free of charge.

How to identify Japanese Knotweed

1. Japanese Knotweed dies back in winter leaving woody bamboo sticks. In spring and summer, bamboo like shoots grow up to 2.1m (7ft) tall. 

In Spring dark red shoots start to appear from the ground, and grow rapidly. 

Once stems are fully formed they become hollow and speckled. Leave protrude from the stems on alternate sides creating a zig-zag pattern.
2. The picture below shows mature Japanese Knotweed leaves. They are shield shaped and up to 14 cm long. Young leaves are rolled and dark red in colour
Look out for:
- Bamboo-like stems
- Leave from either side creating a zig-zag
- Mature stems are hollow
- Sprouts from ground in spring
- 'Dies' in winter
