Dealing with difficult perennial weeds
Most garden weeds can be controlled by my mulching and/or ground sheeting techniques without the use of chemicals, but when you are overrun with one of the top 5 UK perennial weeds, it’s time to reach for some additional help with a chemical weed killer such as Roundup weedkiller or smothering the area with a landscape ground sheeting and covering with bark chips or similar
Japanese Knot Weed
In most cases we recommend spot treating with Roundup weed killer with a small hand spray or a weed wipe.
