Overview
The mango is one of the great tropical fruit trees, a big, long-lived evergreen that can reach 10 to 50 feet (3 to 15 m) with a canopy almost as wide. It carries its leathery leaves year-round and breaks into bloom in the cool months, then ripens fruit through the warmth of late spring and summer. In the right climate it becomes the backbone of a garden, a tree you plant once and live beside for decades.
Mango is happiest where it's genuinely warm. It suits USDA zones 10 and 11, asks for full sun, and wants soil that drains freely, since constant wet at the roots is one of the few things that will undo it. A young tree needs steady water to settle in, but a mature one shrugs off a dry spell and even uses the cool dry stretch before flowering as a cue to bloom.
It pays to know what you're planting. A grafted named cultivar fruits true to type in a few years, while a tree raised from a saved seed may take the better part of a decade and bear something quite different. The fruit flesh is a pleasure to eat, but the tree sits in the poison-ivy family, so the skin, sap, and leaves carry an allergen that calls for a careful hand.
Care
The short version: full sun and real warmth, deep well-drained soil, and steady water for a young tree that you ease off as it matures. Feed through the growing season, prune after harvest to keep it open, and never let the roots sit wet.
Light
Mango wants full sun, as much as the day will give. It will tolerate a bit of partial sun, but light is what drives strong growth and a heavy bloom, so a shaded tree flowers poorly and bears little.
Water
Water a young tree deeply and regularly while it establishes, then back off as it matures, since an older mango handles drought well. Hold off water during the cool dry spell before flowering to nudge it into bloom, then resume as the fruit develops. The one rule it won't forgive is waterlogged soil.
Soil
Give it deep, well-drained loam or sandy loam. Mango tolerates a wide range of ground but not constant wetness, and a pH from 5.5 to 7.5 keeps the nutrients available.
Temperature
This is a tropical tree that grows across a broad warm band, roughly 32°F to 104°F (0°C to 40°C), but it has no tolerance for hard frost. A freeze damages young trees and flowers outright, which is why it's held to zones 10 and 11.
Humidity
Mango likes the air on the humid side, around 50% to 80%, in keeping with its tropical home. That said, damp, still air during bloom is exactly what fungus wants, so airflow matters as much as moisture.
Feeding
Feed through spring and summer while the tree grows and fruits, using a balanced fertilizer with micronutrients. A mature mango appreciates nitrogen along with periodic iron, zinc, and manganese, especially where the soil runs alkaline.
Pruning
Prune after harvest to hold the height down, take out dead or crossing branches, and open the canopy so light and air reach the center. Tip-prune a young tree to build a sound framework early. Wear gloves, since the sap can irritate skin.
Repotting
A container or dwarf mango wants fresh soil every 2 to 3 years, with a light root-prune at the same time. Roots circling the pot or pushing out the drainage holes, fast drying after a watering, and stalled new growth all say it's time.
Size & spacing
A standard mango is a large tree, reaching 10 to 50 feet (3 to 15 m) tall with a spread of 10 to 40 feet (3 to 12 m). Give it serious room, well clear of buildings, pavement, and overhead lines, or choose a dwarf cultivar for a small garden.
When to plant
Mango runs on the tropical calendar. The tree flowers in winter to early spring, sets fruit that ripens from late spring through summer, and goes in the ground in spring once frost is past and the soil has warmed. Where seasons are mild and frost-free, the timing is more a rhythm than a deadline.
Northern hemisphere
Southern hemisphere
Typical months for a temperate climate: start earlier in warm zones, later where spring frosts linger.
- Sow: fresh seed started under warmth in spring (seedlings vary; grafted cultivars preferred)
- Plant: spring after all danger of frost has passed and soil is warm
- Harvest: flowers in winter to early spring; fruit ripens late spring through summer
Hardiness
USDA hardiness zones: 10–11
Temperature: down to -1°C
Troubleshooting
Most mango trouble lands during bloom, when wet weather and fungus decide how much fruit you'll keep. Learn to read the panicles and young fruitlets and you can step in before a problem costs you the crop. Match what you see below, then act while it still helps.
Black sunken spots on flowers, fruit, and leaves
This is anthracnose, a fungus that flares up in warm, wet weather while the tree is in bloom. It blackens the flower panicles and leaves dark tear-stained streaks down the fruit, which knocks back the crop you'll get. Prune to open the canopy, keep water off the flowers, and clear away any infected debris on the ground.
Fix:
- Improve air circulation by pruning
- Apply protective fungicides during flowering and fruit set per label
- Remove and destroy infected plant debris
White powdery coating on flowers and young fruit
A dusting of white on the panicles points to powdery mildew, which takes hold when nights run cool and days stay dry through bloom. The coated flowers and tiny fruitlets blacken and drop, so you lose the crop before it ever forms. Watch the panicles closely as they open and start sulfur or a labeled spray at the first sign, before it spreads.
Fix:
- Apply sulfur or labeled fungicides at early bloom
- Repeat applications during flowering as needed
Plenty of flowers but little or no fruit set
A tree can bloom heavily and still drop nearly everything when cool, wet, or cloudy weather during bloom holds back pollination and invites disease. The other common cause is alternate bearing, the tree's habit of resting after a heavy crop year. Keep disease in check during flowering, feed in balance without overdoing the nitrogen, and ride out the off-years patiently.
Fix:
- Ensure disease control during bloom
- Maintain balanced fertility and avoid excess nitrogen
- Be patient through off-years of alternate bearing
Toxicity
The ripe flesh is safe and a genuine treat for people, but the rest of the plant asks for respect. Mango sits in the same family as poison ivy, so the skin, sap, and leaves carry urushiol, an allergen that can raise an itchy rash on sensitive skin. Around animals the bigger danger is the large pit, a real choking and blockage hazard, so keep stones, peels, and prunings out of reach.
Toxic to
Cats · Dogs · Horses · Rabbits · Livestock · Birds
Safe for
People
Cats Caution
A lick of ripe flesh won't hurt a cat, but the sap and peel carry the same urushiol that irritates skin and can leave the mouth sore. The real worry is the pit, which is far too big to pass and can lodge in the gut, so keep stones and trimmings out of reach.
Dogs Caution
Dogs often beg for sweet mango flesh and handle it fine in small amounts. Trouble starts when one chews the peel or sap and gets a sore, itchy mouth, or worse, swallows the hard pit and ends up with a choking risk or a blockage.
Horses Caution
Fed sparingly, a piece of peeled fruit is usually no problem for a horse. The peel and leaves hold irritating urushiol compounds, though, and a whole pit is a real choking hazard, so offer only small, pitted, peeled bites.
Rabbits Caution
A rabbit can nibble a thin sliver of ripe flesh now and then, but the sugar is heavy on a small gut and best kept rare. Skip the peel and leaves, which carry the family's irritating resins, and never let a rabbit near the pit.
Livestock Caution
Goats, sheep, and cattle will browse fallen fruit and mostly cope, yet the urushiol in peel and leaves can irritate, and gorging on windfalls invites stomach upset. Whole pits are a choking and blockage risk worth fencing against.
Birds Caution
Many birds relish ripe mango flesh, and a little is a fine treat. Keep them off the peel, sap, and leaves with their irritating compounds, and clear away pits so a curious bird can't get hung up on one.
People Flesh safe
Ripe mango flesh is delicious and safe to eat. The catch is the skin, sap, and resin, which carry urushiol, the same allergen as poison ivy, and can raise an itchy rash on sensitive people. Peel with care, wear gloves if your skin reacts, and keep the sap off bare hands.
Mango is in the Anacardiaceae (cashew and poison-ivy family); the sap, peel, and leaves contain urushiol-related compounds (mangol) that can cause contact dermatitis in sensitive people, much like poison ivy. Wear gloves when pruning or peeling, and avoid skin contact with trimmings. The large hard seed/pit is a choking and intestinal-obstruction hazard if swallowed by pets.

Varieties
Hundreds of mango cultivars exist, from market workhorses to prized dessert fruit. These are the ones you're most likely to meet by name.
Tommy Atkins
The workhorse of the commercial trade, grown everywhere for its firm flesh, good disease resistance, and the toughness to ship well.
Kent
A late-season favorite for fresh eating, with sweet, almost fiberless flesh.
Haden
A historic Florida cultivar known for its colorful fruit, though it leans toward anthracnose and tends to bear in alternate years.
Alphonso
The famous Indian dessert mango, prized for its rich, aromatic flesh but quick to suffer in frost.
Keitt
A large, late-ripening mango with nearly fiberless flesh that hangs well on the tree.
How to propagate
There's more than one way to start a mango, and the method you pick decides how soon it fruits and how true it comes. Grafting and air-layering give you a known, faster-bearing tree, while seed is the easy but patient route.
GraftingModerate
Warm season when bark slips and rootstocks are actively growing · Grafted trees commonly begin fruiting in about 3-4 years
Grafting is the standard commercial way to raise a mango, joining a veneer or cleft scion onto seedling rootstock during the warm season while the bark slips and the stock is growing. The payoff is a tree that comes true to type and starts bearing in roughly 3 to 4 years, years ahead of a seedling.
Air layeringModerate
Warm growing season · Roots form over several weeks to a few months before severing
Air-layering clones a chosen tree onto its own roots, a good option when you want a copy of a favorite. Done in the warm growing season, the wrapped branch sends out roots over several weeks to a few months before you cut it free, though gardeners reach for it less often than grafting.
SeedEasy
Sow fresh seed promptly in spring as viability is short · Seedlings can take 5-8 years or more to fruit and may not be true to type
Growing from seed is the easy route, but mango seed loses viability fast, so sow it fresh in spring as soon as you can. Expect a long wait of 5 to 8 years or more before fruit, and be ready for surprises, since polyembryonic seeds often come up as clones of the parent while monoembryonic ones throw variable hybrids.
Myths
Mango is completely safe to handle because the fruit is edible.
Mango belongs to the poison-ivy family, and its sap, peel, and leaves carry urushiol-related compounds that can raise an itchy rash on sensitive people. The flesh is safe to eat, but the peel and the rest of the plant deserve a careful hand.
A mango grown from a saved seed will fruit true to type and quickly, just like the parent.
A monoembryonic seed gives you a variable seedling that can take many years to fruit, so what you grow may look nothing like the fruit you ate. Grafted named cultivars fruit true to type and far sooner, while polyembryonic seeds can come up as clones of the parent.
