Sam has done an excellent job on the invasive knotweed over the past two years, with three more to go until eradication. He has always let me know when he is coming and then come when he said he would. Hoping for a successful end to the treatment, and to the weed. Thanks Sam.

We requested quotes for a Japenese Knotweed survey from a number of companies in relation to a house purchase. Whilst other companies simply quoted an amount for a survey, Pete responded to our specific needs in great detail and followed up with a phone call in which he advised against a survey. Instead he offered valuable (and free) advice which has helped us enormously.

Frequently Asked Questions

Why is Japanese knotweed a problem?

Japanese knotweed (Reynoutria Japonica) is a huge problem in Portsmouth due to its ability to out-compete native plants for resources and light, weakening the soil’s integrity with its deep, penetrating root system. In many cases, efforts to remove outer growth are futile because roots can extend several metres deep into the ground, making it extremely difficult to ultimately eradicate.

Japanese knotweed can damage concrete foundations due to expansive rhizomes in search of water, causing walls to crack and buckle. Many homeowners have found themselves facing costly repairs caused by Japanese Knotweed infestations on their properties.

What happens if I have Japanese knotweed?

If you suspect you have Japanese knotweed, it is important to address the issue as quickly as possible due to its ability to spread rapidly and cause significant damage. It can overpower garden borders, invade properties through cracks in brickwork, block drains, and create large underground root systems.

We offer various control methods such as herbicide treatment and fire-freezing, administered by qualified professionals. If left untreated it can seriously impact the quality of your land or property which may lead to loss of value in the future.

Should I be worried if my neighbour has Japanese knotweed?

Japanese knotweed can be an unwelcome and often unsightly guest in gardens. If your neighbour has it growing on their property, then there is certainly cause for concern. Not only does this aggressive plant blur boundaries by encroaching onto neighbouring land, but it is capable of quickly damaging buildings and infrastructure as its network of roots burrow deep.

It is, therefore, important to act swiftly to ensure the spread of Japanese knotweed is minimised in order to protect both your landscape and property values. To do this, you may need to discuss the issue with your neighbour and enlist the help of a professional service that specialises in Japanese knotweed eradication.
