Fertilization regimen reduces environmental impact of landscape palms

Palms are an important part of the environment in subtropical and warm temperate climates. Palms' aesthetics and small "footprints" make them desirable in a variety of landscapes throughout the southeastern United States. Unfortunately, palms also have some of the highest nutrient requirements of any plants. Timothy Broschat, a scientist from the University of Florida's Fort Lauderdale Research and Education Center, explained that most palms in the southeastern US are grown in sandy, nutrient-poor soils. "The result is that most landscape palms in this region are deficient in one or more elements," he said. "These deficiencies are conspicuous and unsightly; they reduce canopy size and vigor, and can become fatal for palms."
