With Japanese knotweed treatment underway it is essential to stay off the treated land i order to prevent spreading it to fresh ground

An appropriate Japanese knotweed treatment plan not only guarantees the long-term removal of this highly invasive ornamental weed plant but also its complete eradication from an infested area.

Japanese knotweed treatment does not rely on just one technique but rather on a multiplicity of approaches to achieve the best results possible.

The fact that Japanese knotweed does not stop spreading once it takes over an area means that the early you take action to stop its growth the better. To ensure complete eradication, you must deal with the foliage of the weed plant together with its tenacious root system all at once.

Elements influencing the cost of Japanese knotweed treatment plan

Response time

The response time is the duration that a specified method takes to have a complete effect on the Japanese knotweed such that removal and eradication are imminent.

It is no secret that certain methods such as the use of chemicals may take a shorter time to act on the weed plant as compared to methods such as the use of barrier membranes. In a nutshell, the quicker the response time of a chosen method, the less the amount of money you will use.

Extent of infestation

Fundamentally, the area of the land affected is the key factor that contributes to assessing the cost of a treatment plan. This is to say; the bigger the area the higher the costs one will have to bear and the reverse is true.

Any infestation of the Japanese knotweed in an area is not to be taken lightly, hence, no matter the cost of the Japanese knotweed treatment plan, it is better to be safe than sorry.

Treatment plan

Another factor that influences the cost of a Japanese knotweed treatment plan is the treatment program; whether chemical or physical that will be suitable for your type of infestation.

For instance, where it is deemed fit to use weed killer herbicides on the weed plant, this can lead to higher costs because the products may have to be purchased more than once taking into account that the weeds may take two to four seasons to be completely eradicated.

Equally, physical methods of removal of the Japanese knotweed such as excavation will attract higher costs as compared to methods such as burying the weed plant.

What should a Japanese knotweed Treatment Plan contain?

Accumulative costs

Depending on the chosen Japanese treatment plan, the costs for seeing the whole process through will always vary.

Basically, the large the infestation, the more its costs and the vice-versa is true. It is important that one is made aware of the amount of money that they are likely to spend so as to completely eradicate this weed plant.

Being made aware of the cost aspect is important as it helps a person to make an informed decision before embarking on a particular eradication method.

Protective measures

Occasionally, the use of certain methods such as weed killers to get rid of Japanese knotweed may have adverse effects on the surrounding environment and even human activities.

For instance, where there is a water body or public water supply system, it is forbidden to use herbicides close to such areas without putting in place enough protective measures to ensure the water is not contaminated.

Equally, where the treatment will be around a residential area, it is important to ensure that children and pets within such an area are protected from coming into contact with any herbicides to be used or any danger that may be caused as a result of action taken towards eradication of the weed plant.

Some of the protective measures include placing warning signs of the ongoing treatment of an infested area. This will inform the general public of the exercise and they will be able to keep off the site.

Additionally, protective covers can be placed along river banks or any water body close to the area that is to be subjected to treatment, the covers will prevent any chemicals from being washed into the water and causing contamination.
