This is part of CUGE’s Training Series on Guidelines to continue our efforts in improving the overall horticulture standard of the landscape industry. This module will provide an overview on rooftop tree and palm planting needs, and how these horticulture requirements are influenced by:

  1. Material selection
  2. Material placements
  3. Material dimensioning

The rationale behind these design recommendations will also be shared. The course aims to impart to participants a realistic perspective on the many needs of trees and palms when planted on the rooftop, as well as the various associated architecture, loading and placement issues that need to be considered upfront during the project design phase, with the overall intention of encouraging feasible and manageable rooftop greenery design.
