melaleuca tree is considered invasive in Florida:
-
ImpactMelaleuca trees are a major invasive species in South Florida, displacing native plants and wildlife, and altering water flow and soil conditions. They can be found in many habitats, including wetlands, marshes, swamps, and coastal hammocks.
-
OriginMelaleuca trees are native to Australia and Malaysia. They were introduced to Florida in the late 1800s as an ornamental tree and windbreak, and later planted to dry up the Everglades.
-
GrowthMelaleuca trees grow quickly, up to 6 feet per year, and can flower five times a year. A single tree can produce 2–20 million seeds, which can remain viable for up to 10 years.
-
ControlThe South Florida Water Management District (SFWMD) has been leading efforts to control melaleuca trees. Homeowners can also help by removing melaleuca trees from their landscapes.
Some ways to control melaleuca trees include:
- Pulling: Pull seedlings and saplings, making sure to remove the roots
- Applying chemicals: Use herbicides containing glyphosate or triclopyr to treat stumps
- Biological control: Use the weevil Oxyops vitiosa, the psyllid Boreioglycaspis melaleucae, or the gall midge Lophodiplosis trifida
