How to Water a Mango Tree
Mangifera indica
Reviewed by Kiersten Rankel M.S.
Quick Answer
Water your mango tree deeply every 7 to 14 days when the top 2 inches of soil are dry. Stretch to every 2 to 4 weeks in winter when the tree slows. Mango roots are deep and prefer a real soak followed by a real dry stretch over frequent shallow watering.
If your tree is in a container, soak until water runs out the drainage holes, then empty the saucer. Standing water at the roots is the fastest way to lose a mango.

How Often and How Much to Water
Adjust the sliders below for your pot size, light, and setting. The numbers assume a well-draining mix with perlite or pumice and a pot or site with drainage.

How to Water Your Mango
Deep soak, then a real dry stretch. The steps below build the wet-to-dry rhythm that mango roots actually want.
1
Use room-temperature water at the base of the trunk so the soak reaches the root zone, not the leaves. Cold water straight from the hose can shock tropical roots.
2
Pour slowly until water runs out the drainage holes (potted) or the soil is moist 6 to 8 inches deep (in-ground).
3
Empty the saucer within 15 minutes for potted trees.
Should You Water Your Mango Today?
Mango trees would rather be a little dry than a little wet. The soil tells you whether to water — never the calendar.
Hold off
Top 2 inches of soil are dark and cool
Leaves are deep green and full of water
Pot feels heavy
Soil sits tight against the pot wall
Branches feel pliable, not brittle
Ready for water
Top 2 inches of soil are dry
Leaves feel soft, and begin to droop
Pot feels light
Visible gap between soil and pot wall
Leaves curl lengthwise
If Something Looks Off
Mango trees are slow to show stress. By the time leaves drop, the issue has been brewing for weeks. Check the soil first to know what direction to correct.
Underwatered
Soil
Dry through the rootball and pulled from the pot wall
Stem
Young branches feel brittle
Leaves
Curl lengthwise, soften, then crisp at the tips
Pace
Inside leaves drop first as decline builds
Next steps
Bottom-soak the pot in a basin of water for 30 minutes
Drain fully and move out of direct afternoon sun while it recovers
Resume the deep-soak rhythm and add a layer of mulch on top of the soil
Overwatered
Soil
Stays dark and damp for a week or more, sometimes with a sour smell
Stem
Soft or darkening at the soil line
Leaves
Yellow from the bottom up with brown spreading from the tips
Pace
Sudden collapse that worsens even after you stop watering
Next steps
Stop watering and move to the brightest spot with airflow
Slip the tree out of the pot. Pale firm roots are healthy; dark mushy roots are rotting
Trim rotted roots back to firm tissue and repot in fresh well-draining mix
Wait until the top 2 inches of fresh soil are dry before the first watering
Got More Questions?
How long should I wait to water after repotting a mango tree?
Water deeply right after repotting to settle the soil around the roots.
Then wait at least 7 to 10 days before the next watering. Mango roots push faster into slightly drier soil after a repot.
Can I grow a mango tree from a seed, and how do I water it?
Yes. Mango seeds sprout reliably in warm moist conditions. Once the seedling is in soil, follow the deep-soak rhythm above.
Seed-grown mangoes rarely fruit indoors, but they make handsome houseplants. Most fruit-quality mangoes from the store are grafted varieties, not seedling-grown.
Do indoor mango trees need different watering than outdoor ones?
Yes. Indoor mango trees dry slower because of lower light and airflow, so they need less frequent watering than the same tree outside.
Let the top 2 to 3 inches of soil dry between waterings indoors. Position near the brightest window you have for the best chance of healthy growth.
My mango leaves are dropping. Is that watering?
Both extremes cause leaf drop. Overwatering yellows leaves from the bottom up, while underwatering crisps them at the tips first.
Check the soil before correcting. If the rootball is soggy and you see soft black roots, that is rot. If the rootball is bone-dry and the leaves are crisp, that is drought.
Should I water differently when my mango is flowering or fruiting?
Yes. Mango trees need consistent moisture during flowering and fruit set, then less water as fruits mature on the tree.
Missed waterings during flowering cause flower drop. Once fruits are sized up, the tree handles longer dry stretches without losing the crop.
Why are my mango leaves curling lengthwise?
Lengthwise curl is the classic mango thirst signal. The leaves narrow to slow water loss before they actually droop.
Check the soil and water deeply if dry. Curling leaves usually flatten back out within a day or two of a real soak.
