Properties across our coverage area face multiple invasive plant threats. Identify your problem and get expert treatment.
Schedule 9Reynoutria japonica
The headline invasive — bamboo-like canes, shovel-shaped leaves and a rhizome that can exploit existing cracks, joints and defects in tarmac, drains and lightweight structures — the risk depends on site conditions and is confirmed by inspection.

HazardousHeracleum mantegazzianum
A towering riverside umbellifer whose sap causes severe phytophotodermatitis — burns and blistering that can recur for years.
Learn more
Schedule 9Impatiens glandulifera
Pretty pink 'policeman's helmet' flowers and an exploding seed pod that flings 800+ seeds per plant up to 7 m — riverbanks become monocultures in two seasons.
Learn more
High-impactRhododendron ponticum
A dense evergreen that shades out woodland understorey, acidifies soil and harbours Phytophthora pathogens fatal to larch and oak.

Garden escapeBuddleja davidii
Loved by butterflies, hated by structural engineers — colonises masonry, gutters, walls and rail infrastructure with surprising root force.

High-impactPhyllostachys spp.
The new boundary-dispute headline. Running varieties send rhizomes 10+ m sideways, popping up in next door's lawn, patio or extension foundation.
Learn moreJapanese Knotweed is listed under Schedule 9 of the Wildlife and Countryside Act 1981, and where it is growing close to buildings, drains or hard surfaces it can affect saleability and lending decisions (RICS Japanese Knotweed and Residential Property, 2022). Our PCA-certified specialists survey, treat and — where the site calls for it — excavate, with the scope confirmed in writing, for residential and commercial sites in Cardiff, Swansea, Newport, Bristol, Bath, Reading, London and Birmingham.
Whether you need a knotweed survey for a property purchase, a mortgage-compliant treatment plan or emergency removal, we deliver fast, effective work. Where suitable, we can provide a treatment plan and an eligible insurance-backed guarantee that may support a transaction; lender requirements vary and the lender and its surveyor make the final decision.
As TrustMark-approved and SafeContractor-accredited specialists, we also control Giant Hogweed, Himalayan Balsam, invasive Bamboo, Rhododendron and Buddleia. Our work protects property value and keeps you the right side of environmental regulation.
