Rear of York House on 24 July 2020. This Silver Birch is at least 3 years old and was blocking the drainage of the bath and sink in one of the flats.

On a quick visual survey of the hoppers on the Hanger Hill Garden Estate flats carried out on 23 July 2020 I found 18 hoppers with plants growing out of them. Many of these hoppers are obviously broken or leaking. Photos of 7 out of the 18 are shown below.
