Pruning Schedule

The city conducts tree pruning services according to industry standards that are tailored to zones and species of trees. The pruning cycles can vary from 18 to 48 months depending on the tree species. In cases where residents want to prune city trees off-cycle, the city offers the option to the residents to pull a no-fee Right of Way Tree Pruning permit and hire the services of a full tree service company with ISA Certified Arborist on staff.

Residents may request service through the city’s GovQA system for emergency-related situations only.

Emergency situations include but are not limited to:

  • Broken and hanging branches
  • Falling and fallen trees
  • Traffic light and sign obstruction

Tree Trimming Over Property Lines

Trees and vegetation that cross into your property from an adjacent property may be properly pruned within your property. Pruning of trees on private property of branches four inches in diameter or greater must be done by a qualified tree trimmer. Pruning of trees may also be done by the property owner with assistance as needed by assisting labor. Pruning tree limbs ten inches or more in diameter on private property requires a tree permit from the tree preservation agency. Please read the City Code to ensure the proper management and pruning of trees to avoid penalty.

 

Tree Pruning on Power Lines (FPL)

There are three different ways for FPL customers to report these conditions immediately:

  • via FPL website,
  • via phone: 1-800-226-3545, or
  • via the FPL App: Power Related Concerns/Tree Trimming Investigation Request

 

When either of these reporting mechanisms is used, FPL has the ability to monitor each of these requests with all of the appropriate resources. See the following documents below for more information:

Black Olives Study

The Black Olive or Oxhorn Bucida tree, Bucida buceras, is a widespread species found in the south Florida urban forest. Approximately 20% of the total shade trees in public areas of Coral Gables are Black Olive trees. These shade trees are commonly attacked by two arthropods, an eriophyid mite, Eriophys buceras, and a caterpillar, Garella nilotica. By-products of these pests such as caterpillar frass and mite-induced galls cause severe staining of sidewalks, streets and vehicles underneath the tree canopy. 

The staining is so aesthetically problematic that dissatisfied homeowners wish to remove the trees. Residents can remove this staining by scrubbing the affected pavement or structure using a diluted mixture of household bleach and water as a temporary solution. 

Studies were conducted by The Davey Institute over a 4-year period in Naples and Coral Gables, Florida to evaluate insecticide treatments against these pests. During 2015 and 2016 in Coral Gables, abamectin trunk injections resulted in excellent reduction in gall formation and staining. Abamectin trunk injections are proving to reduce the staining to property, and preserve the positive environmental benefits of mature Black Olive trees in the urban forest. This represents an environmentally rational approach with none of the drawbacks associated with foliar applications or soil drenching.The City of Coral Gables performs treatment injections of 2000 Black Olive trees every March and April during the peak season for mite and caterpillar activity.
