Trees, Salt Tolerance and Dunes

Trees provide many environmental benefits including habitat for wildlife, soil stabilization, shade, and removing pollution from the air.  Due to the effects from coastal flooding, king tides and sea level rise, non-salt tolerant trees are being negatively impacted with greater frequency leading directly to a loss of environmental benefits. In Fort Lauderdale, trees play a major role in urban forest sustainability and dune stabilization. As such, Fort Lauderdale is utilizing a more salt tolerant tree palette to enhance the resiliency of its trees; species such as Seagrape, Pitch Apple, Green and Silver Buttonwood and Gumbo Limbo do very well in dune/high salt environments, helping protect our shorelines from tidal events and storm surges. Incorporating more salt tolerant trees throughout the City's urban forest will continue to increase its sustainability and resiliency in the face of ongoing environmental challenges.

New Tree Planting

So Spring is upon us and I normally receive a lot of questions pertaining to how and where to plant new trees in Fort Lauderdale. The first part is to identify a location on your property that is in need of a new tree whether for aesthetics, shade a source of fruit etc. Be aware that new tree planting in the City right-of-way swale will require a City landscaping permit, unless the tree(s) were provided through the City's Adopt A Tree Program. For more information on the City's Adopt A Tree Program please visit the following website: City of Fort Lauderdale Adopt A Tree Program. Next pay attention to the onsite conditions, does the proposed location have existing overhead or underground utilities, does the site receive ample sun or shade and how much room is available for a future mature tree (canopy and root room). Remember to call 811 before you dig to verify utility locations. Then you select an appropriate tree species for the location based on answers to the above questions. Make sure whatever tree you choose to plant is free from defects (girdling roots, poor structure, diseased etc.) and a minimum Florida No. 1 grade.  As for planting the tree dig out a hole that is at least 2-3 times the size of the new tree root ball, remove all burlap/wiring etc. from the rootball, place the tree on a firmly packed soil base within the planting hole backfilling around the root ball with a mix of native/top soil gently tamping it in place. Make sure that the final planting height is about 2-3" above grade as the tree will settle over time. Depending on tree size bracing and staking may be necessary. Make sure to use trunk protectors when bracing to avoid strap damage, and often trees are braced on three sides. Do not tighten the braces too much as a limited amount of play will be essential for allowing the tree to develop proper taper. Establishment watering is critical for the first 3-5 months. A general rule of thumb is to water every day for the first 30 days, every other day the next 30 days, every 3-4 days the next 30 and every 5-7 days the last 2-3 months.
