Dan,

Thanks for your reply.  On a similar note, can thickly planted perennials take
too much  water, nutrients, and ozygen away from Oaks so that initially the
oaks would be stressed (and susceptible to Oak Wilt)?  In the last 2-3 years,
I have replaced thin Kentucky Blue Grass with many woodland perennials under
my oaks.  I haven't added dirt but have added an inch or two of humus.  Maybe
the roots have had a chance to grow upward by now.
