I have probably at least a ton of apple tree prunings. Everything from
twigs to several whole trees that we culled. Some are from this spring
and others from past years, probably as long ago as four years. This
year's wood is still green of course but, the three and four year old
stuff is plenty dry.
I also have at least a two lifetime supply of mulberry which I've had
good luck with just using chunks of heartwood.
Bark on or off? I've seen reports of both ways but, is there any
consensus by the experts?

If the bark is tight to the log, I leave it on. If it is loose, I remove it
due to funky stuff, like dirt and insects and fungi, which get trapped.

Agree with Dave. Some woods, like oak, have a thick bark that may be loaded
with fungus and other forest growth and it should be removed. Apple has a
thin tight bark so I just leave it on. As for age, I've used it from an hour
off the tree to years old with good results. Ditch the twigs though.
