Hey there, tree novice here so be nice lol.
We moved into this house this year and as I was doing some mulching and planting new trees for fall, I learned about the root flare and how that needs to be exposed to open air. I’ve been wondering what to do for this dying dogwood that’s just got a lovely shape, so I was excited to learn that maybe this would help.
Well the root flare is DEEP. Couple questions: is she too far gone and should I just plant a new tree here? And if not, can I expand this ditch a bit to provide that air or do I need to move lots of dirt from here to level it? See pics. I put the horihori there for scale. All the mulch is moved back a bit from the hole so that’s all dirt where the tool is.

What is the obsession with root flare in this sub?
Why do you say it’s dying? That growth on the bark is just lichen, not to worry.
The root flare should be exposed, and you will have to move dirt away from the trunk area to level the ground more around it. I would call a certified arborist in your area to come and do a fertilizer injection well into the roots. Wait until spring to see how it rebounds after flare exposure and fertilizing. A thoughtful pruning of any dead branches in the spring may be all that is needed.
Are you sure also that it’s a dogwood? I have one and never goes colorful at all in the fall.
I did receive a comment from a previous post (changed the title) that said they don’t know if it can be saved but that I’m on the right track. Just looking for additional info/ thoughts!
I think that this tree can be saved. Continue reducing the mulch volcano.
Prune any visible deadwood. Maybe treat the roots with a phosphoric acid fungicide to boost resistance to Phytophtera and V. Wilt.
Good luck!
