Cumbria, United Kingdom
Hi. I have recently planted a new hawthorn blackthorn conservation mix hedge. The hedge has plastic spiral guards. The problem being, most of the plants have small black dots on the leaves with many plants also having a white furry growth. ( fungal? ).
Is this normal given the very wet summer months we are experiencing or do I need to treat? If so can anyone point me in the right direction? Enthusiastic amateur I'm afraid.
