I have a Quercus michauxii (Swamp Chestnut Oak) sapling in my front yard. Today, there was a hole dug next to it about 4 X 4 X 6" deep. The inside edge was less than 6" from the trunk. It wasn’t a tunnel, as it didn’t continue on beyond.
A. Is this likely to hurt the tree?
B. I was surprised that I saw really no large roots at all - just some small feeder roots, and one 1/4" thick root about 2" down. Is it unusual that an oak of 1.5" caliper and 10’ tall wouldn’t have any visible roots in this situation?
3. What did this?
I did cover the hole back up.
