Hey,

Need some advice with an older crab apple that hasn't been cared for in a long time, by the looks of it.

The tree is covered in what I thought was scale but seems to be something else now that I have a hi-res pic. I did see major aphid issues last summer. Thoughts?

There's clear, and orange ooze coming out of random spots in the bark. Could be cytospora or borer holes, not sure at all.

A number of the crotches have what looks like black soot lumps on them. Looks like sooty mold fungus, the aphids probably had a major contributor to this problem.

My treatment for just about every tree disease is: Cut out the infected part.

The simplicity is reminiscent of Gary Larson's take on equine medicine:

I've had that thought but that means pretty close to the ground...

The ooze looks like it may be borers - Michael Phillips has a good discussion:


The bumps I haven't seen before - kind of reminds me of sapsucker damage, but seems too random.

If growth is good. I would try to encourage it and maybe spray compost tea a bit more..
