Japanese Knotweed Control

Giant KnotweedOne of the main reasons for failure in controlling Japanese Knotweed is due to its root systems known as rhizomes. These systems are incredibly extensive and deep rooted often extending some 3 metres into the ground and 6 metres outwards. There may be many stems connected together via their rhizome system with all plants benefiting from the ability to share energy produced by other plants. If you kill just the visible part of the plant you can guarantee it won’t be the last you see of your Knotweed problem.

By far the cheapest & most effective treatment for the removal of Knotweed is Safe Chemical Control.

After an Invasive Weed Survey has been conducted and on acceptance of our Eradication Management Programme we will begin treatments ASAP, ensuring the weed has had 2 or 3 applications of herbicide before the winter time, when the Japanese Knotweed dies back naturally and hibernates until the spring, when growing begins more aggressively and spreading faster than the year before.

We offer 2 methods to treat Japanese Knotweed:

  1. Application by Knapsack Spraying
  2. Stem Injection

Application by knapsack spraying will kill both the visible and underground rhizome system of the weed effectively and is the most common form of eradication. In larger spreads of the JK, channels are cut through the infestation so product reaches all affected areas fully. On smaller infestations the method is simply spraying the affected area with the product.

Stem Injection is much more specific and effective. The product is injected directly into the stands of JK and can move throughout the rhizome and root system much quicker, eradicating the whole infestation more aggressively while reducing any risk of damage from the rhizome system quicker also.

A combination of the 2 applications can be used together to aggressively attack the weed and this way effectiveness of the product is much more intense.

Our programme of eradication usually last between 2 and 3 years. For larger infestations, programmes of up to 5 years are put in place. We re-assess the Japanese Knotweed at the beginning of each year of the programme which starts in spring time.

When we have successfully eradicated the weed you will receive confirmation of this in the form of a certificate of eradication and then a guarantee period of up to 10 years will be put in place. We offer Insurance Backed Guarantees too which offers another level of cover; perfect for home buyers or sellers. These guarantees ensure that the weed is completely eradicated and cover any costs associated with further treatments should there be any re-growth.
Most mortgage companies, lenders and banks accept the conditions of our 5 year Insurance Backed Guarantee but most prefer the 10 year IBG for extra protection.
