Dogwood is drowning

I had two dogwoods installed in May. One has done very well while the other has struggled. I thought it was stress at first. Then I thought it could be watering but know that is not the issue. I've sent the pictures to the landscaper and he thinks the tree is drowning due to the wilting, browning leaves. Lime was already added to the clay and fungicide and insecticide also sprayed to rule those out. It was burlap ball installed in the red clay soil of Georgia on a slope.

My question is...how I check to see if the root ball is sitting in a pool of water at the bottom and is drowning? I don't want to damage roots by digging with a shovel unless that is the best way. Any suggestions on how to check without causing more damage?

Pics of dogwood. I've had some issues with boxwoods and root rot in clay soil. Do you have a soil prober than can sample the soil next to the roots? See how long it stays wet after watering. Possibly get some compost and have that surround the root ball to improve soil draining in that area. What fungicide did you apply? Captan? Have also heard you can spray copper fungicide on the leafs to help mitigate the issue if it's root rot.

The landscaper came out today to look at the tree and they wound up digging the tree up by the root ball. It came up very easily and we found that the roots had not worked through the burlap at all. There was a greyish tan clay covering the ball too. He guessed the dogwood was not grown in a Georgia nursery since the clay was so different. We took the burlap off, added new soil in the hole, and broke up the ball a bit to allow the roots some freedom and ability to soak up nutrients. Now we wait to see if it was too late. Hoping it recovers.
