Master the Art of Growing an Alphonso Mango Tree Successfully

Alphonso is a mango variety from India, where the fruit has been grown for more than 4,000 years. Mangoes reached Florida in 1833, and today they thrive in South Florida yards and provide harvests for homeowners. This guide covers Alphonso mango tree size, the growing conditions it needs, and how to care for it from the minute it's in the ground.

What is an Alphonso Mango?

Alphonso is a named variety of the common mango, Mangifera indica 'Alphonso'. It comes from India, where mangoes have been grown for more than 4,000 years, and is often called Hapus or its nickname, the King of Mangoes. Like other mango cultivars, it's a tropical evergreen tree with shiny, dark green leaves and a rounded canopy.

Much of what you taste in a mango is really aroma, and the Alphonso has a very distinct one. The sweetness comes from the sugars that build up as any mango ripens. Dietary fiber is also low in the Alphonso, which measured about 2 percent in a comparison of eight varieties, while the highest in that group, Langra, came in near 6 percent.

Growing Conditions and Care for Alphonso Mango Trees

Mango trees are suited to tropical and subtropical climates and need full sun for a good harvest. They adapt to many soils, including the sandy and limestone soils common in South Florida, as long as the ground has proper drainage. A well-draining, loamy soil with a slightly acidic to neutral pH also works well. A tree can handle an occasional flood but not waterlogging. If your yard holds water, plant on a mound of native soil two to three feet high and four to six feet across. In California, the best sites are warm and sunny and sit away from cool coastal fog.

When you plant, dig the hole three to four times as wide as the pot and set the root ball level with, or slightly above, the surrounding soil. Fill the hole with the soil you removed, mixed with no more than about half organic matter such as compost, and leave the fertilizer out. After watering, add a layer of mulch to hold moisture and keep weeds down 8 to 12 inches back from the trunk.

Regular watering is important while a tree is young, starting with water every other day for the first week and then once or twice a week for the first couple of months. Once the tree is around four years old, it only needs water during long dry spells in spring and summer. Too much water can cause root rot and poor fruit.

Young trees do best with about six light feedings during their first year, using a fertilizer made for fruit trees and following the amounts on the label. Once the tree starts bearing, switch to a formula that's low in nitrogen and higher in potassium, as extra nitrogen can hurt fruit quality. Granular fertilizer works best between March and August.

Fruit Production and Harvest Season

A grafted Alphonso mango tree usually starts bearing three to five years after planting. It flowers from December through April, depending on the weather and variety, and the fruit takes about 100 to 150 days after flowering to mature. In California's warm growing regions, the flowering period runs from late winter through early spring, and fruit development carries on from spring into summer.

In Florida, most mango varieties mature between May and September, with the biggest harvests in June and July. Alphonso may fall within that window, although timing shifts from year to year. In California's warm growing regions, the Alphonso is a mid-season mango (June to August), and harvest runs from late June to early August, usually peaking in July.

Pick mangoes while they're fully mature but still firm. If you're not sure a fruit is ready, cut one open. Yellow flesh near the seed, rather than white, means it's mature even if the skin hasn't changed color. Skin color alone can mislead because it varies by variety.

Let harvested mangoes ripen at room temperature, ideally 70 to 75°F, which usually takes three to eight days. Move them to the refrigerator only after they're ripe, since early chilling can injure the fruit. Some people react to mango sap, so wear gloves when you pick. Pick up fallen fruit regularly, as it attracts squirrels and other animals.

Frequently Asked Questions

How Big Do Mango Trees Get?

Left unpruned, they reach 30 to 60 feet tall and 30 to 50 feet wide. Yearly pruning after harvest keeps a tree closer to 12 feet.

How Long Does an Alphonso Mango Tree Take to Produce Fruit?

A grafted tree usually begins bearing three to five years after planting.

Can I Grow an Alphonso Mango Tree in a Pot?

A large pot works for a while. Start with one 10 to 15 inches wide with drainage holes, move up as the roots fill it, and prune the tree to a size you can manage.

How Cold Can an Alphonso Mango Tree Get?

Mature trees can handle a few hours at 25°F with minor damage, but young trees start to suffer around 29 to 30°F, and flowers and young fruit are damaged by a few hours below 40°F. Cover young trees before a freeze, and bring potted trees into shelter.

When Should I Prune a Mango Tree?

Prune soon after you finish picking, before October, so next year's flowering isn't affected. Remove any dead or diseased wood at the same time.
