If you find yourself in a battle with Knotweed, it is critical to not engage in typical weed defence strategies. In fact, these strategies will spread Knotweed further rather than control it.

Knotweed is no ordinary weed.

Resist your inclination to mow, cut, or weedwhack. Because knotweed can be spread by plant fragments, these ordinary gardening tactics will quickly turn one knotweed plant into an army of thousands of knotweed pieces looking to plant themselves anywhere they may land.

Plant parts stuck to any cutting equipment, like your lawn mower, will easily be spread to other areas of your property while you use it. Before you know it, you'll be surrounded by knotweed.

Pulling and digging are just as unlikely to get rid of it. Knotweed's root system is capable of growing 3 meters deep and as far as 20 meters horizontally. Any fragments left hiding in the ground will give rise to more knotweed plants. And if you do dig it, what do you do with the infested material? Knotweed does not compost easily and most composting facilities cannot take the soil mixed with the root material. You don't want to pass infested material onto unsuspecting neighbours.

The best way to target Knotweed is with specially-selected herbicide, applied by a professional applicator. Knotweed requires a product that will translocate throughout the plant so that the extensive root system is killed.

Natural products that only burn the foliage will not win the knotweed battle.

Even with the right herbicide, knotweed still puts up a good fight. There is no silver bullet with this invader. It takes multiple applications to be successful so don't lose hope! Persistence is the key to victory in the knotweed battle.

Stay focused, committed, and recruit the right help from a certified applicator and you will eventually win the war.

To prevent future battles with knotweed in your neighbourhood, be sure to warn your neighbours. Show these training materials. Resistance in numbers is much more likely to be successful in keeping lurking knotweed at bay.

Good luck as you defend your property against Knotweed.
