Burning Japanese Knotweed due to its vigorous invasive nature, the resulting consequences are far-reaching depending on the size and area affected.
The Japanese knotweed has established a reputation of not leaving any stone untouched when it invades an area with grave damages to property, biodiversity, and the natural environment, which necessitates that quick action is taken to remedy the situation.
To this end, methods such as burning Japanese knotweed have been well utilized to ensure that the weed is eradicated. For that reason, the question of whether one can burn the Japanese knotweed is in the affirmative.
Notably, considering that the Japanese knotweed has become a menace posing a great danger to any invaded area, various legislations have been put in place to safeguard the proper management and removal of this weed, the reason being to control the ability of the weed to spread due to poor management especially by individual effort of human beings for instance when they want to burn, bury or even cut the weed.
In this regard, the next segment of this article will explain in detail what one ought to do when burning Japanese knotweed to ensure full eradication:
Drying of the Japanese knotweed
Preferably, once the Japanese knotweed has been cut or uprooted from the ground, the strands of the weed should be laid out on the sun or a very hot surface to ensure that all the moisture from them dries out.
Failure to ensure that proper drying occurs poses the danger of the weed infestation returning because moisture encourages easy and quick re-growth.
Manner of burning
In order to get the best results from the burning Japanese knotweed, it is absolutely important to ensure that the whole plant is put through the fire and completely burned.
To this end, it is always recommended that one uses an incinerator that will lead to fewer emissions and damage to the surrounding environment.
Removal/disposal of the burnt Japanese knotweed substance
Although very rare, it is possible to find that certain stems or rhizome of the Japanese knotweed has survived the burning process and may invoke a new infestation if not well disposed of.
Therefore, this makes the disposal process very important after burning. For that reason, the recommended means of effectively disposing of the already burnt substance is by burying it or taking it to a suitable off-site destination.
Dos and Don’ts of Burning Japanese Knotweed
In this segment, we explore the necessary precautionary measures that an individual must keep in mind whilst burning Japanese knotweed and anticipating the full removal of the weed from an infested area. The following are the dos:
- Ensure that the landfill site where you intend to dispose of the burnt weed is well controlled and authorized to carry out such an exercise and one in possession of an environmental permit to do so. The reason for this is to prevent the weed from being disposed of in a careless manner that will invoke a new infestation. Complete removal of the weed should be the end goal.
- Inform the disposal facility early in advance to make proper arrangements to avoid the burnt substance staying for long unattended as this may lead to it being moisturized and possibly lead to the growth of rhizomes that may not have been completely burned.
- During transportation to the disposal site, it is prudent that one takes all the steps necessary to ensure that the burnt substance is transported in an enclosed material, the purpose being to prevent any spillage while on transit.
- Depending on the locality, it is also important to familiarize yourself with the laws applicable to the procedure recommended for burning, disposal, and removing the Japanese knotweed, as not to face any government agencies’ punitive costs.
- You must not dispose of the burnt substance accompanied with any other waste material as this poses a danger to the weed finding suitable conditions for re-growth.
- Do consult with the authorities on occasions where the burning is expected to be large scale. You need to keep in mind the safety precautions to protect yourself, the property and the environment.
The Don’ts are as follows:
- Do not burn the Japanese knotweed unless the plant has been fully dried and deficient in moisture.
- Burning Japanese knotweed should not be done in an open place as this may lead to emissions and the possible spread to adjacent areas aided by factors such as strong winds.
- Do not bury or dispose of the burnt substance in any area other than a recommended landfill site because this may invoke a fresh growth in cases where the burning was not fully effective such that the rhizomes of the weed were not destroyed.
- Avoid taking the Japanese knotweed out of the infected site for burning. When burning Japanese knotweed, it is always recommendable that this should always occur at the site of the weed growth. The reason for this is that with minimal transportation from one place to another, one is likely to avoid the further spread of the weed through unknown droppings of the weed along the way. Also, on-site burning ensures that the entire weed present is well and truly burned to the very last bit until an area is declared free of the invasive weed.
Will The Weed Be Fully Eradicated Through Burning?
The answer to the above question is in the affirmative.
However, burning Japanese knotweed is deemed an effective method if an individual follows to the letter the particular laid out procedures mentioned above, which in a nutshell are to ensure that the weed fully dries before subjecting it for the actual burning in an incinerator.
Once the burning process has ended, the remaining substances must be removed and disposed of in a landfill facility or any recommended site that handles such substances.
Finally, one must follow the dos and don’ts as outlined above to ensure that the burning is successful and that the Japanese knotweed is fully eradicated from an infected area.
