ASCARegistered Consulting Arborist

• There is neither a higher authority nor a more
  objective voice in the arboricultural profession
  than a Registered Consulting Arborist (RCA) on
  matters involving the legal, environmental and
  aesthetic considerations of trees and plants.
  Those who earn the RCA designation are routinely
  called upon for expert testimony, damage
  assessment and appraisal, municipal and
  commercial landscape planning and development,
  tree preservation, hazard assessment, and other
  situations requiring expert knowledge and
  experience in the arboricultural industry.
  Registered Consulting Arborists must meet
  stringent requirements for technical education
  and experience, successfully complete the
  requirements of ASCA's rigorous Consulting
  Academy program, and produce a series of
  consulting reports that meet strict professional
  review standards.

Plant so about the top 10 of the root ball is
above the landscape grade. This ensures that the
point where the top- most root emerges from the
trunk remains at or slightly above ground even if
the root ball settles. Cover the sides of the
root ball with mulch, or perhaps soil. Form a
water ring (berm) from mulch only if trees will
be irrigated with a hose. The water ring is not
needed if trees will not be watered after
planting or if trees are irrigated with a low
volume head. Water rings made from soil can lead
to problems because the soil is typically pushed
over the root ball later. Roots will grow
extremely fast into the mulch and surrounding
soil and trees establish quickly using this
planting technique.
