Warm, wetter weather means that Japanese knotweed is thriving across Devon this season.

Property Care Association reports an early growth of the plants’ distinctive red stems in February, well ahead of its usual growing season.

Daniel Docking, the PCA’s Invasive Weed Control Group technical manager, says the current climate conditions could have a detrimental impact on native plant species.

Daniel said: “We can still expect late season frosts and dry weather in March and April, but Japanese knotweed has already started to establish itself and the resilience of the plant will mean it is in a strong position to thrive.

“At the moment many plants are doing well due to the weather conditions, including native species.

“But we’d still suspect the temperature to drop, meaning many plants will slow down their growth pattern.

“However, Japanese knotweed will be largely unaffected by these changes and that means it can start to dominate environments, with more opportunities to spread.”

“As Japanese knotweed becomes more visible, we encourage anyone with concerns about the plant to seek expert help."
