What should I do for a retaining wall around oak trees?
+1
The brick retaining wall that we put around the oak trees in front of our house are falling down. Need suggestions on what to put around the trees. the trees were in mounds when we bought the house so we have to go over two and half feet high.

Without seeing what you're talking about, it's difficult to help.
That is quiet a lot to cover,I can only think of a trellis perhaps,you could also use stakes with garden wire but are not so pretty with the height you need,however you could plant climbers to cover the stakes.
The problem with any type of retaining wall around trees is that they grow - why do you think you need a retaining wall, does it have to go around the trees or can you create a larger wall further out?
I prefer modular ones as they are easier to reset http://thehtrc.com/2010/retaining-block-wall-five-rules
