Our advice on identifying Japanese knotweed
Japanese knotweed changes in appearance as it moves through seasons, making it difficult to spot if you’re not familiar with it. Below is a quick guide to help you recognise it year round.
Spring
Dormancy to growth
Look for pink or red buds at ground level. These develop into hollow, asparagus-like shoots that quickly grow into thick, bamboo-style shoots.
Summer
Peak growth
Stems shoot up to 3 metres tall, with purple-specked nodes and broad green leaves forming a dense, light blocking canopy.
Autumn
Flowering and decline
Clusters of creamy-white flowers appear. Leaves turn yellow and begin to droop as stems start to die back.
Winter
Dormancy
Above-ground stems become brittle and hollow. Rhizomes underground stay alive, ready to regrow in spring.

Japanese Knotweed Excavation and Removal in Residential Property


Vegetation Clearance, Japanese Knotweed Removal and Giant Hogweed Removal at Brentford Locks, London

Japanese Knotweed Excavation and Removal and Vegetation Clearance in Chesterfield
ECS were brought in to undertake a thorough clearance of the site, which covered approximately 3 hectares. ECS had 2 teams of 3 operatives carrying out tree felling for 2 weeks on site. All trees were chopped and chipped, with the chippings and root balls removed from site as part of the works.
Once the initial clearances had taken place, ECS were also contracted to remove two infestations of Japanese Knotweed that were present on site. Due to the planned development and site constraints, the only solution that fit the client’s timescales was a full removal from site.
