  1. Arboriculture Resources, Certifications, and Techniques David S. Vandergriff dgriff@utk.edu

  2. Topics Covered • Arboricultural Resources • Certifications • Proper Planting Techniques • Diagnostic Techniques • Professional Practices

  3. Arboriculture is the science and art of caring for trees, shrubs, and other woody plants in landscape settings. ( Harris and others, 1999)

  4. Arborist – An individual engaged in the profession of arboriculture who, through experience, education, and related training possesses the competence to provide for or supervise the management of trees and other woody plants. (ANSI A300 Part 3 – 2001 Pruning)

  6. 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.

  7. 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. Click here for photo
