Invasive Plant Control
We are specialists in removing invasive plants including Japanese knotweed, for both commercial and domestic customers. Invasive plants can be of concern to homeowners, commercial land owners, developers, insurers, banks and other lenders. We offer clearance and treatment of your invasive weed to prevent the plant from returning. In some cases this will require on-going treatments to fully eradicate the plant.
How we remove invasive plants
We use a system of integrated weed control meaning that we combine physical control with herbicide control where possible. For various reasons physical control may not be possible or viable and that's when we'd look at herbicide alternatives. We always opt for the one which is safest and has the least environmental impact. It is a trade-off as the plant being treated has an impact of its own hence the treatment.

Prevention & control
Why are invasive plants a problem?
When a non-native species is introduced, the environment may not have the capacity to manage the spread of that species. The invasive plant may outcompete native species for resources preventing it from growing and therefore reducing biodiversity. In addition to the effects on the environment, invasive plants can also have an effect on you:
Invasive plants can very quickly spread and ruin your garden
Some species are incredibly difficult to remove
If left untreated they can cause costly damage to your home
They can delay or prevent your house sale
If they spread they can create acrimonious and expensive legal battles with your neighbours

Japanese Knotweed Control
Japanese Knotweed (Fallopia japonica) is a non-native species, originally introduced to the UK as an ornamental garden plant. It has an aggressive growth of up to 10cm a day, with dense bamboo-like stems that grow up to 2m high. It can be incredibly difficult to remove if not managed early on. While it is not illegal to have Japanese Knotweed in your garden, you can be prosecuted if it causes a nuisance and spreads into the wild. If you are buying or selling a home you can read more about the legal implications in this RHS article.
Horsetail (Equisetum arvense), is an invasive, deep-rooted perennial weed. It spreads quickly and forms a dense carpet of foliage. It can grow as much as 2m deep interfering with block paving and driveways. It has a deep extensive rhizome system and spore dispersal which makes it very hard to eradicate by simply digging out. Occasional weeding is not effective and can make the problem worse, as the plant can regrow from any small pieces left behind.
Himalayan Balsam Control
Himalayan Balsam (Impatiens glandulifera) is a non-native invasive plant introduced to the UK in the 1800's. This plant is particularly virulent along river banks, allotments and wasteland. The plant spreads rapidly smothering vegetation in its path. It can grow up to 3m tall and each plant can produce up to 800 seeds and disperse easily. This species is listed on Schedule 9 of the Wildlife and Countryside Act in England and Wales therefore, it is an offence to plant or spread into the wild.
Bindweed (Calystegia sepium) is a familiar plant in the UK with its white trumpet like flowers. However, left unmanaged, it can twine around plant stems and choke plants in your borders and flower beds and even lawns. The bindweed roots spread from sections of stem (rhizome) and may penetrate up to 5m deep and grow rapidly. Established plants can spread outwards by 2m or more in one season.

Before & After
Q&A with Charles
Will Japanese Knotweed affect the value of my property?
There are over a million homes in the UK affected by Japanese knotweed. Having this weed in your garden could devalue your property or cause the sale to be delayed or fall through, due to misinformation or fears of what the knotweed might do. So it's good to know the facts and what you can do to remedy the problem. When selling your home you'll need to declare the Knotweed and provide a management plan of what you are doing to eradicate the problem. For more information, take a look at the RICS (Royal Institute of chartered Surveyors) guidelines here.
