Found weird white and brown lumps on Escallonia plant in May. They were powdery if I pushed one off. Now in October it's as if there is a tiny bit of candyfloss left behind. Spiders like this corner. Next-door Acer may now be dead :-( (lost leaves mid-summer) but Escallonia and Apple tree (to the right) are healthy. Have many breeding garden snails around too.
