Re: Cork oak in the lawn (some general irrigation points)

Thanks to Sean for his response to my questions about planting a cork oak
in my lawn.

I do indeed water the rest of my yard with drip irrigation so I am familiar
with the idea.  As I've been thinking about this little cork oak, I've also
thought about planting it in a raised planter in the center of the lawn --
that way, the soil would be above the lawn level and though the spray
might hit the trunk of the tree, it would have little residual effect on
the rootball..... if I do so, can you comment on what diameter to make it
and how high to make it?  I'm thinking about building a retaining wall of
broken concrete and filling it up (might need a barrier to keep the soil
from leaking out.  My soil is generally fairly sandy as I am in a river
valley.  I add compost regularly.

By the way, I also have a small Englemann Oak.  Would that be a better
choice for a lawn?  I prefer the cork oak as I think it has a narrower
crown, but the Englemann could go there as well.
