The area to be covered that was mentioned sounds big enough to have an
arc on the end of the sugar maple filled with decomposed granite the
color of flagstone and a root barrier put down. Less inpact on tree,
roots and hardscape.

We're planning on having a 1000 ft2 flagstone patio installed. We
have received estimates for both a dry install with rock/stone(?) dust
and a mortored install. What are the pros and cons of each. We live
in Northern Virginia by Washington DC. We do have a large, mature
sugar maple that will be approximately 6 feet from one corner of the
patio. Our concerns are these roots and heave. We want a very flat
surface which leads us to mortored, but are afraid of cracking in the
cement due to the roots. We believe that we can repair any root
movement in a dry install, but worry about the overall flatness over a
period of time. Thoughts?

cool site
