Royal palm care can be tricky, as the trees are somewhat prone to disease and mineral deficiency, but they are also relatively tough. They are hardy. They can tolerate salt spray, though they don’t do well with salty soil. They can withstand strong winds. The trees grow very quickly, especially if given plenty of fertilizer and water. While moderately drought tolerant, they do best with regular watering and will grow well in damp, swampy areas. When young they can manage with partial shade, but once they reach maturity, they really need full sun – and, of course, royal palms require plenty of room to accommodate their large stature.
