Thank you all for the helpful inputs
I looked on allt he links provided - also inspected the surrounding trees
No junipers or cedar in the immediate surroundings
I have in my tiny garden also a plum, a cherry and a pear - all transplanted on small roostock for them to be samll - I have a tiny garden
I attracheda pic of the other apple tree next to it - the black thing is the fruit tree grease - and I feel the same thing with the finger like projections is turning up in two othe places already
All lesions seem to be on the initial rootstock - and not on the transplant
I decided it must be the crown gall - I will attach the internet pictured that I thought looks most similar
I must sadly say that I took the two apples out with as much root as I could - altohough I must have left plenty of little roots in
. Roots seemed ok.
