Japanese Knotwood is sometimes known as Japanese Bamboo because of its hollow stems with raised nodes that give it a bamboo appearance. Widely considered a weed, this aggressive perennial plant has an invasive root system that causes damage to building foundations, roads, and retaining walls.
The weed forms dense sturdy colonies that crowds out other species and its network of roots can withstand extremely low temperatures, Japanese Knotwood control is imperative. It necessitates the eradication of the roots and the repeated killing of the plant material above the ground.
If it is attempted to eradicate it by pulling up the weed or by trying to cut and remove stems, it will never leave a site. Attempting to remove the roots like this is not recommended as their depth and hardness will cause it to fragment causing new weeds to grow.
Japanese Knotwood control is most efficiently handled by professional Japanese Knotwood removal experts, not only because it is resistant to most weed killers, but due to the following reasons:
- The underground roots can be as much as three meters deep, making their removal and eradication extremely difficult.
- This quick-spreading plant can reach tennis-court size in just one year and the rhizomes can be seven meters beyond the edges of the above-ground growth.
Therefore, any soil with even parts of the roots in it must not be spread elsewhere on the site but must be removed from the area entirely. If not, the rhizomes will continue to grow and spread on the property.
Professional removers will know which herbicide is essential to use, as it should be a systemic one that goes through the plant into the root system.
Japanese Knotwood control is a tough job that necessitates even the equipment used for its eradication be thoroughly cleaned so that no bits of the roots are left on them. It requires a great deal of diligence and tenacity, along with the services of professional removers.
