Meet a "superweed", an alien invader you don't want on your property.

Knotweed -- native to Asia -- may be knocking at your door, preparing to wreak havoc, and you don't even know it. Educate yourself about this alien invader so it won't catch you by surprise! And if you do have it, learn what to do about it.

Knotweed, often referred to as False Bamboo, is capable of growing just about anywhere and is considered one of the world's most invasive species. Sun, shade, streamside, roadside, your favourite park, knotweed is indiscriminate when it comes to where it chooses to invade. And once it gets there, it grows rapidly, as much as 4 centimeters a day.

If it chooses your property, your home is vulnerable to its tremendous strength. Like an iceberg, what you see is only a fraction of what is happening beneath the surface. Knotweed's extensive root system is capable of sending shoots up strong enough to grow through tiny cracks and weaknesses in anything including foundations, driveways, roads and septic systems. The threat of its impacts are taken so seriously in the UK that homeowners have been unable to obtain property insurance or a mortgage on properties infested with knotweed. In one case that was reported in 2011, a new home was condemned that had knotweed growing right into the floors and walls.

Like a true invader, knotweed resists any attempts to stop it. This is no ordinary weed. It may as well laugh in the face of typical weed control tactics such as mowing, pulling, digging, and natural herbicides. There is no silver bullet with this one. Even with a professionally applied herbicide treatments, knotweed infestations often require years of repeated attacks before they are eradicated. The bottom line.... You don't want this stuff.

You may wonder why you weren't warned about this. How did it get this bad? Like a good alien invader, knotweed spread silently, largely undetected, targeting unsuspecting landowners and often helped along unwittingly by well-meaning people. And because we had never seen or experienced an invader of this caliber, we greatly underestimated its ability to hit home.

Knotweed is no longer free to expand its territory in BC. In 2011, Knotweed was added to the BC Weed Control Act which requires any land owner or occupier to control it. As a result, knotweed is under attack in battles launched across BC. To be successful, everyone needs to unite and work together because knotweed doesn't respect fences. That's why the ISCMV, FVIPC and SSISC, with help from the Real Estate Foundation of British Columbia, have made these educational materials. Stay with us to learn more about what it looks like, how it spreads, dos and don'ts... and to learn of the possible impacts and implications to your property.
