pin size black spots on trunk & limb

brass_tacks(8b/GA)May 4, 2010

While I was pruning dead branches off the River Birch I noticed that most of the dead twigs and branches had very tiny, dot-like black markings. It doesn't come off with a rubbing. The spots are thick in number, separated by maybe 1/16 of an inch. The leaves on the limbs with these spots are few in number.

I found the same thing while pruning the Weeping Youpon.

Some of the Burfordi Holly & Nelly Stevens have the same kind of thing.

Can anyone say what this might be and hopefully someone will have a suggestion as to what I can do.

Tough to say without images. Can you post some please?

Maybe I can get one of my grands to come over with a camera. I'm going to see if I can get something to remove the black spots. If it is a scale, it is very flat. Come to think of it, I think I saw these tiny things on my Bloodgood maple. I'll try alcohol to see if it will rub off.

I am having the exact same problem. The brach on the left is healthy and the branch on the right is dead and has those tiny pin sized black spots. Does anyone know what this is or what I can do? I don't want to lose this tree!
