How to Plant a Mango Tree (Beginner-Friendly)

Planting Mango Trees from Seed

1. Remove the seed from a ripe mango fruit and clean it thoroughly.
2. Carefully open the hard husk and take out the inner seed.
3. Place the seed in a warm, moist environment until it begins to sprout.
4. Once sprouted, plant the seed in a pot with well-draining soil, laying it flat and lightly covering it.
5. Place the pot in full sun.

Planting Mango Seedlings or Nursery Trees

1. Dig a hole twice as wide as the root ball.
2. Place the seedling or grafted tree at the same depth it was growing before.
3. Backfill with native soil and gently firm it in place.
4. Ensure the tree is upright and stable.

Mango Tree Growing Requirements

Soil

Mango trees thrive in well-draining soils that prevent waterlogging while still retaining enough moisture for roots. The ideal soil type is sandy loam or loamy soil, rich in organic matter, with a slightly acidic to neutral pH of 5.5–7.0. Poorly drained or heavy clay soils can suffocate roots, encouraging fungal diseases such as anthracnose and root rot. Incorporating organic compost, aged manure, or coconut coir improves soil aeration, fertility, and microbial activity. When planting in less-than-ideal soil, creating raised mounds or planting on a slope can enhance drainage. Additionally, a 2–3 inch layer of mulch around the base helps conserve moisture, regulate soil temperature, and suppress weeds, further supporting healthy root growth.

Water

Watering needs vary depending on the tree’s age and growth stage. Young seedlings require consistent moisture to establish deep, strong roots; water them deeply 2–3 times per week in dry conditions, keeping the top 6–12 inches of soil moist. Overwatering must be avoided, as saturated soil promotes root diseases. Mature mango trees are more drought-tolerant and generally need less frequent watering. During flowering and fruit development, water moderately to prevent stress, which can cause flower drop or poor fruit set. Drip irrigation or soaker hoses are recommended to deliver water directly to the root zone while reducing leaf wetness, which can lower fungal infection risks.

Temperature and Humidity

Mango trees are tropical and subtropical plants, preferring warm temperatures between 75–95°F (24–35°C). They are highly sensitive to frost; temperatures below 40°F (4°C) can damage young shoots, flowers, and fruits, while extreme heat above 105°F (40°C) may cause sunburn on fruits and reduce fruit quality. Humidity plays an essential role in flowering and fruit development; moderate to high humidity levels (50–70%) encourage better pollination and reduce flower drop. However, once established, mango trees can tolerate periods of lower humidity. Planting near structures or trees that block strong winds can protect blossoms and young fruits from mechanical damage, as wind can also desiccate leaves and flowers.

Sunlight and Location

Mango trees require full sun exposure for at least 6–8 hours daily to optimize photosynthesis, flowering, and fruit production. Trees planted in partial shade may survive but will grow slowly and produce fewer flowers and fruits. Choose a location with ample space, as mature mango trees can reach 30–100 feet (9–30 meters) in height and develop a wide, spreading canopy. Proper spacing also ensures good air circulation, reducing humidity around foliage and limiting fungal disease outbreaks. Avoid low-lying areas prone to flooding, as stagnant water can suffocate roots and increase disease risk. Consider planting on slightly elevated ground or using raised planting beds for optimal drainage.

Mango Tree Maintenance and Care

Fertilizer

Mango trees benefit from regular feeding to promote healthy growth, flowering, and fruit production. Apply a balanced fertilizer containing nitrogen (N), phosphorus (P), and potassium (K), ideally with micronutrients like magnesium, zinc, and iron, which are crucial for mango tree health. Young trees should be fertilized every 6–8 weeks during the growing season, while mature trees typically benefit from 3–4 applications per year, particularly just before and during flowering. Avoid over-fertilizing with nitrogen, as this can encourage excessive vegetative growth at the expense of flowers and fruits. Organic alternatives such as compost, well-rotted manure, or seaweed extracts can also improve soil fertility and structure while supporting microbial life in the soil.

Pruning

Pruning is essential to maintain the tree’s shape, size, and overall health. For young mango trees, prune to establish a strong central leader and remove competing shoots. For mature trees, prune lightly to remove dead, diseased, or damaged branches and improve airflow and sunlight penetration into the canopy. Proper pruning reduces the risk of fungal diseases, encourages new flowering shoots, and makes harvesting easier. Avoid heavy pruning during the flowering season, as this can remove potential fruit-bearing branches. Always use clean, sharp pruning tools to prevent spreading pathogens.

Mulching

Applying mulch around the base of a mango tree provides multiple benefits. A 2–4 inch layer of organic mulch—such as wood chips, straw, or compost—helps retain soil moisture, regulate soil temperature, suppress weed growth, and gradually improve soil fertility as it decomposes. Keep the mulch at least 6–12 inches away from the trunk to prevent moisture buildup against the bark, which can lead to rot and attract pests. Regularly refresh the mulch layer to maintain its effectiveness.

Potting and Repotting

Potted mango trees require extra attention to ensure healthy root growth. Choose a large container with good drainage holes and use a well-draining potting mix enriched with organic matter. Repot young trees annually to accommodate root expansion, while mature trees may need repotting every 2–3 years. During repotting, prune any circling or damaged roots and refresh the soil to replenish nutrients. Adequate container size and proper soil help prevent root-bound conditions, which can stunt growth and reduce fruit yield.

Overwintering

In cooler climates or regions prone to frost, mango trees must be protected during winter months. Potted trees can be moved indoors to a bright, sunny location or into a greenhouse. For outdoor trees, frost cloths, burlap wraps, or temporary shelters can shield them from freezing temperatures. Watering should be reduced during winter dormancy, as overwatering in cold conditions can promote root rot. Ensuring proper winter protection allows mango trees to survive and thrive when temperatures rise again.

Common Mango Tree Pests and Diseases

Pests

1. Aphids – These small, soft-bodied insects often cluster on new growth and flower buds, sucking sap and causing leaves to curl or distort. To prevent infestations, encourage natural predators like ladybugs, regularly inspect new growth, and treat affected areas with neem oil or insecticidal soap.
2. Scale Insects – Similarly, scale insects attach to stems and leaves, feeding on sap and gradually weakening the tree. **To keep them under control, prune infested branches, apply horticultural oils, and maintain the tree’s overall health and vigor.
3. Fruit Flies – Another common threat, fruit flies lay eggs inside developing mangoes, and their larvae feed on the fruit, leading to premature rotting. To avoid damage, use fruit fly traps, harvest fruit promptly, and remove any fallen or infested fruits from around the tree.

Diseases

1. Anthracnose – This fungal disease causes black spots on leaves, flowers, and fruit, often resulting in fruit drop and reduced yield. To prevent it, plant resistant varieties, prune for good airflow, avoid overhead watering, and apply fungicides during flowering when necessary.
2. Powdery Mildew – In addition, powdery mildew appears as a white, powdery fungus on leaves, shoots, and flowers, which can stunt growth and reduce fruit set. To minimize risk, maintain good sanitation, prune crowded branches, apply fungicides if the infection is severe, and ensure proper sunlight and air circulation around the tree.

How to Harvest Mangoes

Mangoes are ready to harvest when they have reached their full size and begin to show a noticeable change in color, often from green to a yellow, orange, or red hue depending on the variety. While mangoes can continue to ripen on the tree, many are harvested slightly unripe and allowed to mature off the tree to ensure better shelf life and handling. When picking the fruit, it’s important to handle it gently and avoid tugging or twisting, as this can damage the branches and affect future fruit production. After harvesting, place the mangoes at room temperature to ripen naturally; they are fully ripe when they develop a sweet fragrance and yield slightly to gentle pressure, indicating they are ready to enjoy.
