How Fast Does

Knotweed Grow?

In 2010 BBC News reported that Japanese Knotweed was costing taxpayers about £150 million per year. These estimates have rocketed recently as the weed appears in landscaping developments, water lines and housing foundations.

Japanese Knotweed has become a big problem for homeowners resulting in mortgage reconsiderations and property problems.

How Japanese

Knotweed GrowsThere are two most

recognisable ways to

eradicate Japanese

Knotweed. The first is to apply a

glyphosate-based weed killer,

the second to dig the roots out

and dispose of the waste.

However, once the knotweed

has been dug up it must legally

be disposed of at licensed

landfills.

How Japanese

Knotweed GrowsThe BBC revealed in that the

government was

experimenting with a plant-

eating predator in 2010, an

insect that is a natural predator

for knotweed.

The weed expands rapidly due

to the aggressive reproductive

nature of the stems. This makes

destroying Japanese

Knotweed an ongoing process

that can take 3-4 treatments a

year.

How Japanese

Knotweed Grows

Science has shown that in

Japan the knotweed is

controlled by its natural

predators. However, in the UK

this fact is not true.

The plant can grow up to 1

metre in three weeks. The

flowering part of the plant

grows rapidly, as do the roots

that spread quick and deeply.

Knotweed Myths

Knotweed is incredibly

aggressive but there are some

myths surrounding the plant.

For example, it is untrue that

Japanese Knotweed can burst

foundations or cause breaks in

the water pipes. In reality, the

Japanese Knotweed simply

grows through any existing

cracks or openings.

Once the roots expand in these

cracks, the cement can crack

causing serious damage.

Knotweed Myths

The cost of eradication has

been estimated at £1.56 billion

by the DEFRA.

In addition to growing at

impressive speeds, Japanese

Knotweed can overcome any

vegetation in its path,

effectively destroying your

garden.
