Tree experts?

[Go Big Red!]

I am wondering if any of you can direct me to a tree specialist.  Not a chainsaw wielding one but one who can give me an idea of what's causing my tree leaves to curl up.

I have a quaking aspen, planted almost three years ago from a nursery and the leaves are curling up on 3/4 of the tree.  The other 1/4 is in great shape.  Any ideas?  Got a good tree doctor?

Just a guess but that frost we had curled up the leaves on a tree of mine but it seems to be budding again.

GBR - One thought. Aspens tend to have extensive, shallow roots. Any chance some portion of the roots were contaminated or injured somehow? Herbicide? RoundUp?  Cut with something. etc.

I forgot about that, but it didn't impact the entire tree.

Not that I am aware of.  No roots are visible and I haven't sprayed near it so I am still searching for answers.

We had something similar with our aspens a year or two ago.
I hand dug and planted about 40 aspens along my back property line about 20 years ago. A year of two ago some of the trees had areas - meaning certain branches where the leaves wilted and turned brown. The trees came back fine the next year. Our conclusion was that it was a response to a lack of water.

We have had quite a bit of rain in the past week, but I still think it's a disease or something.  The leaves are shrinking and curling up, kinda like reverse budding.  I did hammer in fertilizer spikes around the drip line so maybe that helps.
