Programme Schedule

Up By Roots

Workshop Words of Wisdom:

“If all the trees on a project die, landscape architecture is not art.”
– James Urban to the American Society of Landscape Architects, International Convention 2012.

Workshop Mission Statement:

“Up By Roots” is a technical and practical workshop on trees, soils, and stormwater for arborists, foresters, civil engineers, urban planners, architects, landscape architects, landscape designers, and park planners to successfully: plan, design, specify, install and manage trees, in the built environment.

Workshop Abstract:

The “Up By Roots” Technical Workshop highlights the practical principles of soil science in combination with stormwater, to facilitate the vigorous growth of healthy trees in the built environment. This workshop includes lectures and “hands on” practical experience in analyzing soil samples and field testing equipment, so that workshop participants practically understand, the underlying scientific principles of tree biology, tree growth, and soil/water relations. Upon completion, workshop participants will be equipped to successfully plan, design, install, and manage large trees and their soil’s, in the urban environment upon completion of this practical, technical workshop.

Who Should Attend?

Successful urban trees that grow large and live to maturity, require the participation of five principal groups of people:

  1. Decision-makers;
  2. Designers;
  3. Associated Designers;
  4. Tree contractors; and
  5. Maintenance providers.

As all five of these groups are required to grow successful urban trees, all five groups will learn valuable lessons about trees and soils from this “Up By Roots” technical and practical workshop. Some experienced professionals attending this workshop, may have experience in a number of these areas; but in today’s world of specialization, many people, will primarily belong in one of the five groups; in either case, plan on attending and learning hands-on and techniques.

A critical audience for this workshop is Designers, and Associated Designers. These two groups include the following professionals: landscape architects, landscape designers, civil engineers, architects, urban planners, park designers, arborists, and foresters. If you are one of these professionals, and have not taken a practical, technical course like this, seriously consider taking this workshop.

Workshop Attendance Size:

To facilitate instructor/attendee contact, this workshop is limited to 30 participants.

Workshop Length: 2 Days, June 12-13 2018

This workshop is 16 hours in length, of which participants will also spend time handling tools, soils and roots.  Participants will also have the opportunity to analyze soil samples with their bare hands.

Workshop Learning Objectives:

These are the learning objectives for the “Up By Roots” technical workshop:

  1. Comprehend the critical, but undervalued role of soil volume, quality, and drainage, in growing large trees to maturity.
  2. Read, identify, and interpret, soil diagnostics from a soil test, off a laboratory report (bulk density, pH, CEC, nutrients, organic matter content, etc.).
  3. Physically examine, and interpret key soil characteristics (texture, structure, etc.) by: sight, smell and feel.
  4. Identify and rank the most important characteristics of a particular site’s soils, which are needed to grow large trees at that location.
  5. Identify, prioritize, and provide, the most critical limiting aspects of a site’s soils, which are needed to optimize tree growth at that location: Salts; Organic Matter, Amendments; Mulches.
  6. Comprehend, identify, and rank the critical structural characteristics, of young trees before planting (root and branch development, root/trunk union position, bark attachment, etc.).
  7. Physically examine young tree nursery stock, and evaluate whether to accept, reject or correct young trees before planting.
  8. Review a set of construction details, and specifications, to successfully grow large trees to maturity, on a pre-selected site.
  9. Physically examine, and diagnose structural problems (non-pest), of established, but under-performing landscape trees.
  10. Create a soil/tree structure, remediation plan for established, but under-performing landscape trees.


We are glad to announce this year’s International Arboriculture Summit to take place at Institute of Vocational Education – Sha Tin Campus in Hong Kong on
