How bad is Japanese knotweed in London?
New data reveals that South East London is one of the worst-affected regions in the UK for Japanese knotweed infestations. According to figures published by Environet UK (March 2024), there are almost 57,000 known occurrences of Japanese knotweed across the UK, with London ranking among the highest concentration areas.
In South East London specifically, Greenwich tops the list with over 157 recorded infestations within just a 4km radius. Close behind are Lewisham, with more than 107 occurrences, and Bromley, with 71 cases reported in the same area. These figures highlight how aggressively this invasive plant is spreading across residential neighbourhoods, gardens, and commercial properties in the capital.
Japanese knotweed typically begins to emerge in March and April, with red or purple shoots pushing through the ground and developing into tall, bamboo-like canes and lush green leaves during summer. Beneath the surface, its powerful rhizome root system can grow up to three metres deep and seven metres horizontally, breaking through concrete, tarmac, drains, and even cavity walls.
Frequently asked questions
How can I tell if I have Japanese knotweed?
Japanese knotweed has bamboo-like stems, shovel-shaped leaves, and clusters of small white flowers in late summer. If you’re unsure, book a professional site survey — we’ll confirm it for you.
Can Japanese knotweed damage my property?
Yes. Knotweed can break through hard surfaces such as concrete, brickwork, and tarmac, leading to structural damage and reduced property value.
Do you offer Japanese knotweed removal near me?
Yes — we cover all of South London and surrounding areas, including Kingston, Windsor, Epsom, Walton-on-Thames, Sunbury, Staines, Croydon, Bromley, and Reading.
How long does the treatment take?
It depends on the size and stage of the infestation. Herbicide treatment plans typically run over 1–3 years, while excavation can provide immediate removal for redevelopment sites.
