In the spring of 2018 I planted this one year old pawpaw seedling.
I guess I was a little sloppy and didn’t get it deep enough and/or the potting mix settled a bit.
Either way, some roots are exposed near the base of the trunk.
The tree seems healthy enough - it doubled in size in its first year in the ground.
The roots have mostly lignified by now.
Any reason to do anything about this, and if so, what would it be?
