Post-Storm Tree and Palm Considerations

Green industry professionals are dealing with the aftermath of last week’s tropical storm force winds.  Here are some tips for responding to customer concerns over wind-damaged trees:

Palm fronds that are damaged or hanging should remain on the palm.  This will help the palm to maintain critical nutrition as it recovers and could make the difference between a palm surviving or not.  It may be 6 months or more until you can make a determination whether severely damaged palms will survive.  Water is critical right now – irrigate as needed.

Trees should generally be saved and restored when: Some major limb(s) are broken but intact lower limbs are available to cut back to, the canopy is only defoliated, only some large limbs are broken, trees which are in reasonably healthy condition and have relatively  SMALL (<6” diameter) trunk diameters are fallen or leaning, and when major anchoring roots have not been fractured.

Trees should generally be removed when: a large co-dominant leader has split out of the lower trunk (such as in the photo above), the lower trunk is cracked or broken, major roots are severed or broken, the tree is leaning towards a target, the remaining tree structure is highly susceptible to breakage, the tree is a nuisance tree or in poor health.

Mangrove Pruning and Local Pruning Codes

Has a customer ever asked you to prune mangroves? Did you know the specifics regarding pruning these trees? An upcoming workshop on October 15 at 6:00pm will cover the requirements for pruning and trimming mangroves and seagrapes. We will briefly look at the three species of mangroves found in South Florida and examine the particularities of each. This workshop will also examine local requirements with regard to pruning and why hiring a certified arborist is beneficial not only to a tree owner but to the tree itself. Knowledge of these items is important to the professional because of regulations that dictate the requirements, procedures, and guidelines regarding pruning and trimming.

Mangroves provide habitat to various species of wildlife and aid in the marine food web support. They also serve as a natural protection from storms, stabilize shorelines, and maintain water quality. Mangroves are also important commercially and recreationally, providing opportune fishing areas. Due to detrimental effects of improper pruning, the 1996 Mangrove Preservation and Trimming Act was established by the Florida Legislature to establish guidelines and regulations regarding the pruning of mangroves.The seagrape also provides habitat and serves as a stabilizer for beach dunes. Seagrapes play an important role in the nesting habitat of sea turtles serving as a natural barrier to artificial lighting. Improper trimming of seagrapes can have an adverse affect on nesting resulting in the establishment of regulations under the Florida Statutes to provide guidelines on trimming and pruning.

The pruning of trees and palms should be conducted in a correct manner and in PBC all pruning should abide by the Unified Land Development Code, Section 6. The code provides general pruning requirements and guidelines that promote proper maintenance of trees and palms and assist in preserving their aesthetic and ecological value.

(Too many rules? Join us as we discuss these regulations at 6:00pm on October 15, in the Mounts auditorium. This program is the sixth of eight in the 2012 Strengthening our Community Tree Canopy Series’ for professionals, a project supported by FDACS and the Florida Forest Service through a 2011 Urban and Community Forestry Grant.  To learn more about upcoming topics in this series, Download the 2012 Urban Forestry Brochure here.  CEUs available for ISA, FNGLA, and LIAF).

FL Whitefly Website ~ Training Reminder & CEU Opportunity

As a reminder, the relatively new Florida Whitefly website (flwhitefly.org) has management information for professionals, homeowners, and educators.  For professionals, this site provides access to an e-learning course  titled “Invasive Whitefly Pests of Florida”.   Following the course, an exam will be presented; professionals who successfully complete the exam will be listed on the website.    I encourage horticultural professionals who treat or plan to treat whiteflies to take the class and exam to increase knowledge, earn one CEU, and get on the list.  Potential customers look to this list to hire professionals who are proficient in whitefly management.

The Florida Whitefly website is a result of a partnership between the University of Florida (UF), IFAS Extension, Department of Entomology and Nematology, Florida Department of Agriculture and Consumer Services-Division of Plant Industry, UF/IFAS Extension-Lee, Miami-Dade, and Palm Beach Counties, Southern Plant Diagnostic Network, IPM Florida, and Pest Management University.

A score of 70% or better on the quiz earns the user one FDACS CEU in one of the following categories: Limited Lawn and Ornamental, Limited Landscape Maintenance, and Commercial Lawn and Ornamental.
