Fungus on plum and pear trees
in Fruit & veg
We have a fungus on both our plum and pear trees and wondered if anyone can tell us what it is and how we could treat it. Also could it be harmful to the fruit? Many thanks in advance for your help.

It’s lichen and it’s a sign that the air in your area is clean and unpolluted.
Enjoy your lichen and take a deep breath.

that are self fertile and grafted onto semi dwarfing rootstock which is suitable for an average front garden. The smaller rootstocks do need better soil than the larger ones though.
