Whether you have just planted your first mango tree or inherited one in your garden, this guide covers everything you need to keep it healthy and productive.
Watering Guide
| Tree Age | Summer | Winter | Flowering | Fruiting |
|---|---|---|---|---|
| 0-1 year | Every 2-3 days | Weekly | N/A | N/A |
| 1-3 years | Twice weekly | Every 10 days | Reduce 50% | Resume normal |
| 3-10 years | Weekly deep soak | Every 2-3 weeks | Reduce 50% | Normal + extra |
| 10+ years | Every 10-14 days | Monthly | Reduce | Normal |
Golden Rule: Water deeply but infrequently. Mango trees prefer dry periods between waterings. Overwatering is the #1 killer of mango trees.
Fertilizer Schedule (Annual)
| Month | Fertilizer | Amount (per mature tree) | Purpose |
|---|---|---|---|
| February | Potassium sulfate (0-0-50) | 500g | Trigger flowering |
| March | Boron + Zinc foliar spray | As directed | Improve fruit set |
| April | Calcium nitrate | 300g | Prevent fruit drop |
| June | Balanced NPK (10-10-10) | 1kg | Support fruit development |
| September | Organic compost | 20-30kg | Replenish soil |
| November | None | — | Allow dormancy |
Pruning Basics
When to Prune
- Best time: September-October (after harvest, before dormancy)
- Never prune: February-May (flowering and fruiting season)
What to Remove
- Dead or diseased branches (any time of year)
- Branches crossing or rubbing against each other
- Branches growing inward toward the center
- Water sprouts (vigorous vertical shoots)
- Low-hanging branches below 1 meter
How to Cut
- Use clean, sharp tools (sanitize with rubbing alcohol between trees)
- Cut at a 45-degree angle, 1cm above a bud or branch junction
- Do not leave stubs — they invite disease
- Apply tree wound paste on cuts larger than 3cm diameter
Seasonal Calendar
Spring (February-April): Flowering
- Reduce watering to stress the tree into flowering
- Apply potassium fertilizer
- Monitor for mango hopper (spray neem oil if found)
- Do NOT prune
Summer (May-August): Fruiting
- Resume normal watering — fruiting trees need consistent moisture
- Net trees to protect from birds and fruit bats
- Support heavy branches with stakes to prevent breaking
- Begin harvesting when fruit reaches mature size and shoulder fills out
Monsoon (July-September): Harvest + Risk
- Harvest remaining fruit before heavy rains
- Ensure drainage — waterlogging kills roots
- Watch for fungal diseases (anthracnose) — apply copper fungicide if spotted
- Prune after final harvest
Winter (October-January): Dormancy
- Reduce watering significantly
- Apply organic compost around base
- Whitewash trunk to prevent sunscald (mix: lime + water)
- Protect young trees from frost with burlap wrapping
Common Mistakes
| Mistake | Consequence | Fix |
|---|---|---|
| Overwatering | Root rot, tree death | Water only when soil is dry 10cm deep |
| Too much nitrogen | Lots of leaves, no fruit | Switch to high-K fertilizer before flowering |
| Pruning before flowering | Removes flower buds | Only prune after harvest (Sept-Oct) |
| Ignoring pests | Damaged fruit, reduced yield | Regular neem oil spray during flowering |
| No drainage | Root rot | Ensure soil drains well, add sand if needed |
On our farm, our orchard management follows a strict seasonal calendar that has been refined over decades. The single most important lesson: less is more. Mango trees are tough — they thrive on a bit of neglect. Overcare (especially overwatering and over-fertilizing) causes more problems than under-care.
Frequently Asked Questions
How often should I water my mango tree?
Young trees (under 3 years): water twice a week in summer, once a week in winter. Mature trees: deep water every 7-10 days in summer, every 2-3 weeks in winter. Always let soil dry between waterings — mango trees are drought-tolerant and overwatering causes root rot.
What fertilizer is best for mango trees?
Use balanced NPK (10-10-10) for young trees. For fruiting trees, switch to high-potassium fertilizer (4-8-12) before flowering season. Apply organic compost or cow manure annually. Supplement with micronutrients (zinc, boron, iron) through foliar spray.
When should I prune my mango tree?
Prune after harvesting (September-October in Pakistan). Remove dead, crossing, or inward-growing branches. Keep the canopy open for air circulation and sunlight. Never prune before or during flowering (February-April) as this removes potential fruit-bearing wood.
Why is my mango tree not producing fruit?
Common reasons: tree is too young (under 5 years from seed), insufficient sunlight (needs 6+ hours), over-fertilizing with nitrogen (promotes leaf growth over flowers), irregular watering during flower bud formation, or frost/cold damage to flower buds.
How do I protect my mango tree from pests?
Common pests include mango hopper, fruit fly, and mealybug. For organic control, use neem oil spray every 2 weeks during flowering. Hang yellow sticky traps for fruit flies. Apply sticky bands around the trunk to prevent crawling insects. Remove fallen fruit to break pest cycles.
