I have four huge Yuccas that stand about 12-14 feet tall and am wondering what kind of root systems they have because they are next to a concrete retaining wall that forms part of the swimming pool. Are the roots likely to damage the wall, and how easy are they to relocate if neccesary?

It is highly unlikely that they will damage the retaining wall because their roots are not agressive in that way. But they are very hard to relocate once they become established. The roots go very deep and are hard to remove. If any roots are left, they will regrow from them.
