We have an ancient apple tree in our garden, remnants from a Georgian orchard and its has developed a strange green mold looking covering over the trunk and wider branches. It produces wonderful cooking apples and I would be gutted if it went so I am wondering if I can somehow create another.
What is a rootstock mate?
If you look up - Orchard Network, which is run by - The Peoples Trust for Endangered Species ( PTES )
They have all the info about what to do / who to notify etc
Ancient orchards, even one tree, can be incredibly important in terms of bio diversity, as there are incredibly rare insects / plant life, fungi etc that can only survive on ancient fruit trees.
