Flowering plum trees (Prunus sp.) are lovely trees that bloom in clusters of showy, often fragrant white or pink flowers. Some flowering plum trees are purely ornamental and don't bear fruit, while others produce edible blue to red fruits containing a single large pit. The flowering plum typically grows 20 to 30 feet tall with a 6- to 12-inch-diameter trunk, and some varieties may grow multiple trunks. Flowering plums are popular landscape and street trees due to their small size and beautiful flowers.
Water your newly-planted flowering plum trees deeply to thoroughly soak the soil around the roots once every week during the first growing season. Water established flowering plum trees once each week while they're actively growing, in the absence of rainfall.
Feed your flowering plum tree once every year in early spring with a slow-release fertilizer made for fruiting or flowering trees. Select a fertilizer that contains nitrogen, phosphorous and potassium, as well as trace elements or "micronutrients."
Prune your flowering plum tree lightly in the spring, after the flowers finish blooming. Remove any dead, damaged, diseased or non-flowering branches.
Treat your flowering plum trees for pest insects like plum curculio or diseases like brown rot and black knot disease. Spray the trees with an appropriate insecticide or fungicide, following the directions on the label exactly.
