By 1st May, the established clumps of Japanese Knotweed at our location are 1.5m in height. Some stalks are almost as high as they reached last year. These are unusually yellow in colour, possibly due to restricted light, owing to a tree canopy above. Unfortunately somebody has mown down the vegetation closest to the track, including the smaller shoots I was monitoring.
New green leaves beginning to dominate the dead stalks of last year
