If you can't find the root flare down a couple of inches, call the nursery and complain. Adjust the mulch as needed so there is mulch up to but not in the couple of inches next to the trunk. I would dig around the trunk and see if the root flare is visible and then level things off so it is clearly "there". The breaking down will help improve the soil, and will be incorporated in the top inches by worms, etc. Up to 4" of mulch won't do any harm to the tree - as you noticed, it will break down and need another inch or so added most years. I really like this tree and was looking forward to shade it could provide the yard down the road. Any help would be appreciated or if you can share any similar experiences with this tree. There is about an inch or two of mulch around the base and none against the trunk. Is there something wrong with the tree? The soil is well drained and not soggy. This last week though more and more leaves are turning red as if this were the end of the growing season. Unfortunately over the past month or so a few leaves would turn a light shade of red and then they would seem to go back to green. This spring it has budded and developed many more leaves and started to grow. It did not do much last year other than hang onto the few leaves it had left from the nursery. We planted an Autumn Blaze Maple tree last year at this time.
