Mango
Mangifera Indica
The mango tree, or Mangifera indica, is a tropical fruit tree known for its delicious, sweet fruit and lush foliage. Native to South Asia, it thrives in warm climates and is cherished for its ornamental beauty as well as its edible bounty.
Everything it needs
9 essentials at a glance
Watering
Mango trees prefer deep watering, allowing the top 2-3 inches of soil to dry out between waterings.
During the growing season (spring and summer), water every 1-2 weeks, increasing frequency in hot weather. In fall and winter, reduce watering to once every 2-4 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaf drop and wilting.
Light
Mango trees thrive in full sun, requiring at least 6-8 hours of direct sunlight daily.
Ideal placement is in a south-facing garden or patio. They can tolerate partial shade but may not produce fruit as abundantly. Ensure they receive ample light, especially during the growing season.
Soil
Mango trees prefer well-draining soil with a pH range of 5.5 to 7.5.
A sandy loam or a potting mix designed for tropical plants is ideal. Ensure good drainage to prevent root rot, and consider adding perlite or sand to improve aeration.
Humidity
Mango trees prefer moderate humidity levels around 50-60%.
To increase humidity, mist the leaves regularly or place a humidifier nearby. Signs of humidity stress include browning leaf tips and leaf drop. If humidity is too high, ensure good air circulation to prevent fungal issues.
Temperature
Mango trees thrive in temperatures between 70-100°F (21-38°C).
They are hardy in USDA zones 10-12 but can tolerate brief periods of cold down to 30°F (-1°C). Protect young trees from frost and extreme heat by providing shade during peak summer months.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10 or 8-3-9, applying it every 4-6 weeks during the growing season.
In fall and winter, reduce feeding to once every 2-3 months. Signs of nutrient deficiency include yellowing leaves (nitrogen), poor fruit development (potassium), and leaf curling (magnesium).
Pruning
Prune mango trees in late winter or early spring before new growth begins.
Use clean, sharp pruning shears to remove dead or crossing branches, and shape the tree to encourage an open canopy. Deadheading is not necessary, but removing excess fruit can help the tree focus its energy on fewer, healthier fruits.
Repotting
Repot mango trees every 2-3 years or when the roots become pot-bound.
Choose a pot that is 1-2 inches larger in diameter than the current one. Signs that repotting is needed include roots growing out of the drainage holes and stunted growth. When repotting, gently loosen the roots and place the tree in fresh, well-draining soil.
Propagation
Mango trees can be propagated through seeds, grafting, or air layering.
For seed propagation, extract the seed from a ripe mango, clean it, and plant it in a pot with well-draining soil. Water lightly and keep in a warm location until germination occurs, usually within 2-3 weeks. Grafting is best done in spring when the tree is actively growing.
When it's unhappy
Yellow leaves
Why it happens
Often caused by over-watering or nutrient deficiency.
How to fix it
Check soil moisture and adjust watering schedule. Fertilize with a balanced fertilizer to address nutrient deficiencies.
Fruit drop
Why it happens
Can occur due to stress from drought, over-fertilization, or poor pollination.
How to fix it
Ensure consistent watering, avoid excessive fertilizer, and encourage pollinators by planting companion flowers nearby.
Leaf spot
Why it happens
Fungal infections due to high humidity and poor air circulation.
How to fix it
Improve air circulation, avoid overhead watering, and apply a fungicide if necessary.
Root rot
Why it happens
Caused by over-watering and poor drainage.
How to fix it
Allow the soil to dry out, improve drainage, and consider repotting if the problem persists.
Pests (aphids, scale)
Why it happens
Common pests that can infest mango trees, especially in warm conditions.
How to fix it
Inspect regularly and treat infestations with insecticidal soap or neem oil.
Care through the year
Spring
In spring, focus on fertilizing and watering as the tree begins to grow. Prune any dead or crossing branches to encourage healthy growth.
Summer
During summer, ensure consistent watering and monitor for pests. Mulch around the base to retain moisture and regulate soil temperature.
Fall
In fall, reduce watering as the tree prepares for dormancy. Monitor for fruit drop and adjust care accordingly to support fruit development.
Winter
In winter, protect young trees from frost and reduce watering to once every 2-4 weeks. Avoid fertilizing until spring.
Toxicity & Safety
Mango trees are generally non-toxic to pets and children. However, the sap can cause skin irritation, and the leaves contain urushiol, which can cause allergic reactions in sensitive individuals. Symptoms of ingestion may include gastrointestinal upset.
Good to know
How often should I water my mango tree?
Water your mango tree every 1-2 weeks during the growing season, allowing the top 2-3 inches of soil to dry out between waterings.
Why are my mango tree leaves turning yellow?
Yellow leaves can indicate over-watering or nutrient deficiencies. Check the soil moisture and consider fertilizing with a balanced fertilizer.
What is the best fertilizer for mango trees?
A balanced fertilizer with an NPK ratio of 10-10-10 or 8-3-9 is ideal. Apply every 4-6 weeks during the growing season.
When is the best time to prune my mango tree?
Prune your mango tree in late winter or early spring before new growth begins to maintain shape and remove dead branches.
How can I propagate a mango tree?
You can propagate mango trees from seeds, grafting, or air layering. Seed propagation involves planting a cleaned seed in well-draining soil.
What are the signs of root rot in mango trees?
Signs of root rot include yellowing leaves, wilting, and a foul smell from the soil. Ensure proper drainage and adjust watering habits.
Can mango trees grow in pots?
Yes, mango trees can be grown in pots, but ensure the pot has good drainage and is large enough to accommodate root growth.
