Hi, I'm looking for some information - hopefully you guys could help out.
Here's my situation: I had some grading work done around my home with a dozer (leveling out some hills, etc.), anyways, I told the operator I wanted to keep the oak tree that is growing in an area he was working in. He shaped the grade around it, looked good, except that the area around the trunk is about 2 feet higher. I mentioned that I thought that probably is not a good idea for the tree, but I'm not sure. Most people I mention it to just start to laugh and tell me to quit worrying, but 2 people already told me that the tree will suffocate, and that I should dig aprroximately a 3 foot diameter around the trunk back to the original grade and just fill it with big rocks to conform to the present grade....is there any truth to this?
FYI, it's an oak tree (don't know what kind, it has pointy ends on the leaves, not round like a bur oak), the tree is about 20~30 years old, about 25 feet tall. Thanks for any input!
