Japanese Knotweed Control

Broadland Lawn Care understand what a problem Japanese Knotweed can be. This persistent weed can grow up to 10cm a day crowding out other plant life in the garden and growing through any spaces it can find in permanent structures in your garden. Japanese knotweed starts growing from early spring and can reach 1.5m by May and 3m by June, the weed dies back between September and November. The weed can grow from a mere 0.4g root. New weeds can grow from the stems, crowns or roots and can appear up to 7 metres from a plant.Japanese Knotweed depth of 3 metres.

How do I know if I have Japanese Knotweed?

  • Fleshy red tinged shoots when it first appears
  • Large, heart-shaped green leaves
  • Hollow, bamboo-like, stem
  • Dense clumps of roots that can stretch several metres down
  • Leaves arranged in a zig-zag pattern along the stem
  • Cream flowers in clusters at the end of July which attract bees
  • Brown stems between September and November

There are some important consideration with Japanese Knotweed over standard garden weeds. The roots of Japanese Knotweed are classed as ‘controlled waste’ and require removal by a licensed carrier. These roots are not allowed in your council bin or local authority waste disposal sites.

Note that is against the law to cause Japanese Knotweed to grow in the wild or to let the weed spread into your neighbours property.

Did you know that those liable for corporation tax can claim a 150% deduction on the cost of removing Knotweed at the end of the tax year under the Finance Bill 1st April 2009.

Broadland Lawn Care charges £10 per stem to remove Japanese Knotweed from your garden.
