Care for a mango tree by planting it in a climate with temperatures that never drop below 30 degrees Fahrenheit, using well-drained soil, watering it regularly and feeding it throughout the growing season. Prune the buds to encourage yearly fruiting.
Choose a planting site with access to full sun and well-drained soil that has a pH between 5.5 and 7.5. Keep the trees spaced far enough apart to allow for plenty of air circulation. If you live in a colder area, choose a location against a south-facing wall for extra warmth. Plant the tree during its dormant period in the early spring in a hole deep enough and more than wide enough to accommodate its root ball. Make sure the crown of the plant or graft scar is just level with the soil's surface.
Water the plant deeply and regularly when the top several inches of soil dry out. Decrease watering once the roots become established to every week or two depending on the type of soil and weather. Stop watering the tree between the time it blossoms and starts to produce fruit.
Feed the tree high-nitrogen fertilizer three times a year during the growing season. Once the tree becomes established, use a 6-6-6 ratio fertilizer six times during the growing season for a few years, and then reduce the feedings to four times a year. Thin out heavy blooms to produce a consistent yearly crop.
