How Do You Fertilize Royal Poinciana Trees?
The royal poinciana is a showy tree in flower. For several weeks in during spring and summer, it is covered with flame-red flowers, 4 to 5 inches across. Even up close the flowers are striking, with four spoon-shaped scattering scarlet or orange-red petals about 3 inches long, Royal poincianas reach 30 to 40 feet tall, but their graceful sunshade-like canopy can be wider than their height. It sheds its leaves in climates that have marked seasons, but in Florida and other areas where the winter is warm and humid, it is a semi-evergreen tree all year. It must be fertilized regularly to maintain its appearance. Fertilize a newly planted tree at four to six weeks after planting during the morning to get them off to a good start, then three times per year for the next three years. Apply one of the annual fertilizations in February and one in October, or apply fertilizer in March and September, with the third application in mid-summer. Fertilize established trees every three to five years du
