will the tree die?
 

Hi I am putting in a retaining wall in my front yard(see reDtaining wall in outside masonary for pic) and will want to bury the base of a maple tree in about 3 ft of dirt. I have been told this will kill the tree. Is this true? The trunk is about 2.5 feet in diameter and probably 8 to 10 yrs old. Thanks Brian

Yes it will kill it. Just piling the dirt up about 3" will hamper it's groth, much more than that will kill the tree.

Okay I guess I will have to re plan the wall so the tree wont get buried. I'm glad I found this out before I killed the tree

30" in 8-10 years? OK. Seems for that age it wouldn't be quite that large.

Can you build around it? No cheap enough way to move it. Maybe you can design around it.
