FERTILIZING Sparingly use a general purpose 10-10-10 once every 3 weeks to 4 weeks from Spring to Summer for faster growth. Alternatively, use a slow-release fertilizer, such as Osmocote, 3 times a year. Halt fertilizing from the Fall to Winter, then begin again in the Spring. Do not allow fertilizer to clump, be sure to disperse evenly. Clumped fertilizer can potentially burn roots, potentially harming or killing a plant. Avoid getting fertilizer on the leaves, flowers, and stems. Do not over-fertilize.

COMMENTS Sometimes called the “kidneys of the coast,” mangroves are magnificent filters and maintain necessary water clarity for offshore corals and near shore seagrasses. Essential native tree to Florida’s ecosystem, laws have been passed to protect these trees. It is against the law to remove a mangrove tree. Moderately growth rate with a horizontal growth habit. Lower soil salt tolerance than other mangroves, so they tend to grow in low parts of regularly flooded intertidal zones. Strong roots withstand the rise and fall of tides, and the unique plant structure is built to endure hurricanes. The entanglement of roots provides shelter to many fish species in Florida. though not necessary. Mangroves provide a home to 200+ species of fish, 150+ species of birds, two dozen reptile and amphibian species, and more than a dozen mammal species. Seventy species of mangroves exist on Earth, and three live in Florida. The national champion red mangrove is in Lee County Florida, documented at 64 feet tall.
