How to Get Rid of Knotweed from Residential Gardens

Is knotweed affecting a property you own, or one you intend to buy? Rest assured, Environet helped thousands in a similar predicament — and we’re ready to help you, too.


Japanese knotweed can be incredibly frustrating to get rid of — if you’re trying to do it on your own. Every time you cut it down or dig it out of the ground, it keeps growing back, as if by magic. It’s a dilemma faced by people all over the UK every day and, if it’s not properly dealt with, it can result in real trouble for your property and you.

If you find you suddenly have Japanese knotweed in your house, you’ll need to take action — fast. This is one weed that grows like wildfire, so if you don’t get some effective Japanese knotweed treatment straight away, it will quickly overwhelm everything in your garden and take over.

As it spreads above ground, it’s also growing out of control under the soil. The Japanese knotweed root system spreads out in all directions and can cause serious problems with buildings. The roots can grow into fissures in walls and damage them. They can also exploit tiny cracks in paved driveways and grow up through them. Plus, Japanese knotweed can interfere with critical piping buried in the ground around your home, leading to even more potential difficulties.

If it spreads to neighbouring houses, you could find yourself in more trouble. It’s illegal to let Japanese knotweed encroach to land and properties around yours. It’s also against the law to dig up the weed and improperly dispose of it. Plus, if you ever wanted to sell your house but still had Japanese knotweed in the garden, it could be next to impossible. Potential buyers would find it hard to get a mortgage for Japanese knotweed infested properties.

All these Japanese knotweed problems can also lead to a steep devaluation of your home. When you’ve done everything to protect and even increase your property’s value, it’s alarming when a plant threatens to wipe a large chunk off its value.

Unfortunately, spraying Japanese knotweed with ordinary weedkiller or trying to dig it all out of the ground usually does not work. You need the experts to come in and kill it off once and for all.
