How to Get a Mango Tree to Grow Fast

Plant the mango tree in a deep, well-drained location that has light, loamy soil. Choose a spacious location that can accommodate the mature mango tree's wide canopy and deep root system. Be sure the location provides at least eight to 10 hours of full, direct sunlight.

Keep the mango tree away from cold temperatures and environments, as temperatures below 30 degrees F quickly kill this tropical tree. Plant the mango tree in a container if your climate includes chilling winter temperatures. Choose a deep, well-drained container, preferably with wheels. Keep the potted mango outdoors during the warm periods of the growing season, from spring through fall. Bring the mango tree indoors before the temperatures fall below approximately 40 degrees, to prevent injury. Be sure that the mango's indoor environment provides plenty of direct sunlight and warm, humid temperatures.

Water the mango tree throughout the spring and summer months to maintain a moist, but not saturated, soil environment. Provide the mango with about an inch of water about once a week during the spring and about twice a week during the hot, dry summer months. Adjust the irrigation schedule during periods of rain to prevent over-watering and increase water levels during periods of drought. Reduce the watering schedule during harvesting periods and increase the irrigation schedule approximately one month later to promote the development of new blooms, as explained by California Rare Fruit Growers.

Feed the young mango tree with a well-balanced, slow-release fertilizer for healthy development. Fertilize the mango tree from early spring through midsummer. Apply the fertilizer according to the package's instructions to prevent over-fertilization and resulting root burn.

Prune the mango tree to promote healthy cell development and uniform fruit bearing. Trim back broken and ailing branches and stems. Thin the mango's interior branches and stems to increase the amounts of air and light that flow through the tree. This also reduces the mango's potential for disease. Complete all pruning cuts just before the mango begins its growing season, but never before the final frost.

Inspect the mango tree regularly for signs of disease and insect infestation. Treat any signs of infection or infestation immediately to prevent injury to the tree and resulting loss of vigor. Use chemicals only when needed, and according to the package's instructions, to prevent chemical injury and loss of harvest.
