Mangifera indica 'Glenn'

The ‘Glenn’ Mango Tree (Mangifera indica ‘Glenn’) is a mango variety that was originally planted in south Florida in the 1940s. The variety is thought to be a descendant of the ‘Haden’ and ‘Saigon’ cultivars. The fruits are similar to standard mangoes, yet they exude a mild, peach-like flavor. The ‘Glenn’ Mango Tree can be grown nearly anywhere in the U.S. and performs well in containers.

  • ‘Glenn’ Mangoes are less fibrous than standard mangoes, making them perfect for desserts.
  • Size can be controlled with frequent pruning.
  • Fruits mature in June or July in most climates.

Plant Care



Glenn mangos tolerate partial sun, 4 hours per day, but they will fruit more reliably in full sun, at least 6 hours of direct light per day.



Water daily when newly planted. Once established, water thoroughly once a week during the growing season.



Use an 8-3-9 fertilizer during the tree's flowering period, then switch to a balanced product designed for fruit trees.

Planting and Care

Planting instructions

When planting a ‘Glenn’ Mango Tree directly into the ground, start by digging a hole three times the width of the container. The hole should be just a bit deeper than the pot itself. Before planting the tree, be sure to break up loose soil around the hole, and remove any debris. Position the tree into the hole so that it is standing erect with the top of the root crown at ground level. Then, backfill with dirt and tamp down lightly.

Watering and nutrients

‘Glenn’ Mango Trees are rarely ever thirsty, but it is important to water them daily for two weeks after transplanting. For the following six weeks, water the planting sites thoroughly every three to four days. Established mango trees will only require once a week watering during the growing season, which can be scaled back to monthly waterings over the winter. When planted in rich soil the trees should not require any additional fertilizer. Otherwise, a light layer of fertilizer will give them the boost they need. Use a fertilizer with a NPK of 8-3-9 when the tree is flowering, and a NPK of 6-6-6 when it’s not flowering.


Mango trees are excellent self-pollinators, meaning they will produce fruit on their own without the need for other nearby trees. This allows a single ‘Glenn’ Mango Tree to be kept indoors in a pot, yet still, supply a small harvest of fruit each year. However, planting additional trees nearby will attract pollinators, increase fertilization, and provide more fruit production. A variety of pollinators are attracted to mango trees, including fruit bats, bees, butterflies, and other insects.


When pruning, try to form an open crown to allow light and air to penetrate to the middle of the tree. The ideal time to prune a ‘Glenn’ Mango Tree is directly after harvest. Overall, the tree does not require much pruning, just remove any dead, damaged, or diseased sections as they appear.

Pests, diseases, and animals

One of the most common diseases in ‘Glenn’ Mango Trees is anthracnose, caused by the Colletotrichum gloeosporioides fungus. This will show up as dark leaf spots, blossom blight, and fruit rot. The fungus not only causes rotting leaves and fruit but the internal deterioration of the tree as well. When needed, a copper fungicide can be applied to combat the fungus. Apply it just before hot, humid weather arrives.


You can expect to harvest your mangoes in the summer months of June and July. Mango harvesting occurs when the fruits are fully grown, slightly firm, and turning from green to a yellowish-orange color. To harvest a mango, simply pull the fruit and watch the stem snap off easily. When you pick a green mango, it will still ripen a few days after harvest. Leave them out for three to eight days at room temperature (approximately 75 degrees fahrenheit) until the inside flesh is soft and sweet.


How large do ‘Glenn’ Mango Trees grow?

‘Glenn’ Mango Trees can grow up to 30 feet tall. However, you can keep mango trees well under this height by pruning the main leader or main stem of the tree. This will stimulate branching. The species naturally forms a round canopy as it matures. When grown in a pot, a ‘Glenn’ Mango Tree will not grow much larger than 10 feet tall, even without pruning. The tree grows relatively fast. An individual plant can go from seed to a small fruit bearing tree in just three or four years.

Can mango trees grow in pots?

‘Glenn’ Mango Trees can be grown in pots. You can expect your mango tree to be smaller and more manageable when grown in a container. Your container-bound tree will benefit from the removal of excess branches and leaves, which will also encourage new growth and keep the tree nicely shaped. Do not expect much fruit production from a single potted mango tree. Adding more trees nearby will help increase fruiting.

How much space does a mango tree need?

At a maximum height of around 30 feet, ‘Glenn’ Mango Trees deserve adequate spacing when being planted. Aim for approximately 25 to 30 feet between each tree. When you plan to keep your trees smaller through pruning, you can shorten this distance to 15 to 20 feet. This spacing will allow the foliage of every tree to receive adequate sunlight, in addition to giving each tree’s roots enough space to thrive. Always be sure to provide ample space between the trees and any homes or buildings.

Does a mango tree require full sun?

‘Glenn’ Mango saplings enjoy the bright sunshine, but not all day direct sunlight. Once your trees begin to mature, they will require as much sunlight as possible. More sun will equate to bigger, juicier, fruits. For potted mango trees, you may need to move them outdoors to achieve full sun. A ‘Glenn’ Mango Tree requires at least six hours of sunlight a day during the growing season. It is best to keep your mango trees located in a south-facing area to harness the full power of the sun.
