The fruits are oval to oblong in shape, with a rounded base and pointed tip, without a beak, and usually weighing no more than 300 to 600 grams. The rind is thin but firm and turns bright yellow when ripe. In full sun, 25% to 50% of the berries turn orange to red, but in shade they remain completely yellow. The taste is intense and sweet, the pulp is fiberless (containing monocots), and the aroma is notably pleasant.

Glenn mango can easily be grown anywhere in the country. Once established, it is reported to tolerate temperatures as short as 30 degrees Fahrenheit. In colder regions, they can be brought indoors during the winter months. It will feel like you are in the tropics. Glenn mango is an ideal variety for home cultivation.

This tree can be grown outdoors in the tropics, but it can withstand cold temperatures as low as 30 degrees Fahrenheit. Another advantage of Glenn is that it is a self-fertilizing tree. This means that while a single tree can produce fruit, two nearby trees can produce a richer harvest.

It is best for the tree to get direct sunlight and warmth.. When choosing a location, whether in a container or in the ground, choose a spot with as much sunlight as possible. If you are placing them indoors, it is best to place them near a window. When planting in the ground, avoid low spots or areas that are prone to waterlogging. Mangoes prefer well-drained uplands or dry areas.


Glenn mango tolerates 4 hours of partial sun per day, but will produce fruit more reliably if it receives at least 6 hours of direct sunlight per day. Make sure to choose a location that gets direct sunlight.


Mangoes are rarely thirsty, but must be watered daily for the first two weeks after planting. The most common mistake made in growing mangoes is overwatering. Water only once every three days for the first six weeks after planting.

After that, reduce it to once a week, and in winter, once every two weeks. During the hot summer months, they may need a little more water than in spring or fall. Potted mangos also need to be watered daily in the beginning. For the first 2 weeks, water when the top 3 cm of soil is dry.


Mangoes are easily burnt by fertilizers high in ammonium nitrate. A natural, organic fertilizer with mycorrhizal fungi or beneficial bacteria is best. A little gardening secret that Indians used to do that works well for mangoes is to bury fish in the roots of the plant. These fish contain many nutrients essential for mango growth.

However, potted mangos benefit from a balanced fertilizer such as 10-10-10 during the growing season. During the flowering period, nitrogen should be reduced and phosphorus and potassium should be applied. But, Mangoes are known to be self-fertilizing, so, you can just let it grow in your homes.

Soil Requirements

Glenn mango will grow best in well-drained soils such as sandy, loamy, or clay soils with a pH between 5.5 and 7.5. You should avoid heavy and wet soils. It prefers deep soils because of its good rooting ability.


Mango trees bear fruit at the ends of their branches. Pruning will increase the number of side branches, so pruning will result in more mango fruit. Mangoes are very forgiving, so don’t be afraid to prune them, but don’t go crazy and scalp them. Furthermore, the purpose of pruning is to allow the canopy to open up and allow light and air to reach the center of the tree. This will reduce the risk of fungus and disease.

The best time to prune mango trees is right after harvest, but in cooler areas it is better to prune just before the mango trees begin to flower. Potted mango trees should be pruned somewhat lightly. Just removing dead, damaged, or diseased branches and shaping the tree usually does not require a lot of pruning.

Pests and Diseases

One of the most common diseases of Glenn’s mango trees is anthracnose, caused by the bacterium ‘Colletotrichum gloeosporioides’. This manifests itself as dark leaf spots, blossom blight, and fruit rot. The fungus not only rot leaves and fruit, but also degrades the interior of the tree. If necessary, copper-based fungicides can be applied to combat the fungus. Spray just before the hot and humid season arrives.


Mango trees are excellent self-pollinators. They produce fruit on their own, even if there are no other trees nearby. Therefore, a single “Glenn” mango tree can be potted and placed indoors and still produce a small crop of fruit each year. However, planting another tree nearby will attract pollinators, increase fertilizer, and produce more fruit. Mango trees attract a variety of pollinators, including fruit bats, bees, butterflies, and other insects.
