Lincolnshire, United Kingdom
My next door neighbour has a Cox's Orange Pippin apple tree which, for the last two fruiting seasons has seen the fruit full of holes and inedible. Could these be wasps? If so when is the correct time to spray - assuming you can spray against them and with what product. The tree is starting to throw out new leaf/blossom shoots but a couple of the branches have small areas of what looks like green lichen. Any help would be much appreciated.
