Mango Grafting at Home: Veneer and Cleft Grafts Step by Step
Mango grafting at home is very doable: grow a desi mango seedling for about a year, take a pencil thick shoot from a Chaunsa, Sindhri or Langra tree you love, and join them by veneer or cleft grafting in the monsoon. The grafted plant fruits true to the parent, usually years before a seedling would.
Seedling mangoes from a gutli rarely taste like the fruit you ate, and they can take many years to fruit. Grafting fixes both problems. If you would rather buy a grafted plant, the fruit plants in pots guide covers that; for choosing varieties to eat, see sweet mango varieties.
In brief
- Season: July to September in Punjab and Sindh; the monsoon is best.
- Rootstock: a desi seedling about one year old, roughly pencil to finger thick (about 1 cm).
- Scion: a 10 to 15 cm tip shoot, 4 to 6 months old, from a healthy fruiting tree.
- Prep: remove the scion’s leaves on the tree about a week to ten days before grafting.
- Methods: veneer (side) graft or cleft (wedge) graft.
- First sign of success: scion stays green past 10 days; buds swell in 2 to 4 weeks.

When is mango grafting season?
The monsoon, July to September on the plains. Humidity keeps the scion from drying out, sap is flowing, and the union has warm weeks to knit before winter. Grafting in May’s dry heat fails often. Indian research stations report good survival in August and September; in Karachi, the same months suit. Islamabad and Peshawar should finish by August.
How do you raise the rootstock?
- In June or July, sow fresh gutlis from desi mangoes (vigorous, local types make good stocks) on their side, 3 to 5 cm deep, in polybags or 6 to 8 litre pots.
- Keep moist in part shade. Sprouts appear in a few weeks, often with coppery leaves.
- Grow them for about a year. They are ready when the stem is about 1 cm thick at 20 cm height and has healthy green leaves.
- For cleft grafting you can also use a younger stock, as long as the top is green and firm.
Defoliate a week ahead
About seven to ten days before you graft, snip off the leaves (keep a short stub of each leaf stalk) on the scion shoots while they are still on the mother tree. The dormant buds in the leaf joints swell and are ready to burst. Grafts made with prepared scions take noticeably better than ones cut the same day with leaves on.
Veneer grafting mango, step by step
Veneer grafting adds the scion to the side of the stock, which stays alive and keeps feeding while the join heals.
- About 20 cm above the soil, on a smooth part of the stock, make a downward cut 3 to 4 cm long, slicing in just under the bark and a little into the wood.
- At the bottom of that cut, make a short angled cut to remove the sliver, leaving a small lip.
- Cut the prepared scion: one long sloping face the same length, and a short cut on the opposite side at the base.
- Fit the scion so the green layer under the bark (cambium) touches the stock’s on at least one long side. Matching on one side is enough.
- Wrap firmly with a thin polythene grafting strip from bottom to top, covering the whole scion except the buds, or cap it with a small polythene bag.
- When the scion is still green after 10 days or more, cut back the stock top above the graft in two or three stages over the next weeks.
Cleft grafting step by step
- Cut the stock off cleanly at 15 to 20 cm, where the stem is green and as thick as the scion.
- Split it down the middle 4 to 6 cm with a clean knife.
- Shape the scion base into a wedge with two sloping cuts of the same length.
- Slide it into the split so the bark lines up on at least one side.
- Tie firmly with grafting strip and cover the scion with a small polythene cap to hold humidity.
- Keep in shade and remove any sprouts that come from the stock below the join.
Veneer or cleft: which should you choose?
| Method | Best for | Main risk |
|---|---|---|
| Veneer | Older, woody stocks; beginners | Forgetting to cut back the stock |
| Cleft | Young green stocks; quick results | The stock dies if the graft fails |
How long does a mango graft take to join?
If the scion stays green after 10 to 14 days, it is probably taking. New buds usually swell and break within two to four weeks. Let the first flush harden before removing the tie, usually after one to two months; a tie left on too long cuts into the bark as the stem thickens.
Aftercare that decides success
- Shade: keep new grafts out of direct sun for about three weeks, under a net or a tree.
- Water: keep the soil evenly moist, never soggy.
- Rub off stock sprouts every few days; they steal the energy.
- No fertiliser until the scion has made its first set of leaves, then a handful of compost.
- Plant out the next spring, February to March, after frost.
- Flowers in year one or two: remove them so the young tree builds roots first.
Why did my mango graft fail?
The usual reasons: the scion dried out (no cap, too much sun), cambium layers did not touch, the knife was dirty or blunt and crushed the tissue, the scion was too old or too soft, or rain got into the join. Graft in dry spells between monsoon showers, cut each face in one smooth stroke, and work quickly so cut surfaces do not oxidise.
Grafting knives are razor sharp; cut away from your body and keep them away from children. Mango sap can irritate skin and cause rashes in some people, so wear gloves and wash it off quickly. If you use a fungicide paste on cuts, read the label, wear gloves and keep it locked away. A seedling or graft planted in a pot will not reach full tree size; for a real crop, it eventually needs the ground.
Grafted mango or seedling: the honest verdict
Graft. A seedling is a lottery on taste and takes many years to fruit; a graft gives a known variety and usually its first fruit within a few years in the ground. If you have no mother tree to take scions from, a grafted nursery plant with a clear graft union and a named variety is the sensible shortcut.
Mango grafting: questions people ask
How do you graft a mango tree at home?
Raise a desi seedling for about a year, prepare a defoliated scion from a good variety, and join them by veneer or cleft grafting in the monsoon, then keep the graft shaded and humid.
What is the best month for mango grafting?
July to September on the plains, when it is humid and the trees are growing. August and September often give the best survival.
How long does it take for a mango graft to take?
A green scion after 10 to 14 days is a good sign. New leaves usually appear within two to four weeks.
Which is better, veneer or cleft grafting?
Veneer suits older, thicker stocks and keeps the stock alive if it fails. Cleft is quicker on young green stocks.
How old should the rootstock be?
About a year old and roughly 1 cm thick for veneer. Cleft can use younger, greener stocks.
Why do you remove leaves from the scion before grafting?
Defoliating a week or so ahead makes the buds swell, so they sprout quickly once the join forms.
Can I graft mango in winter?
Success is low in cold weather. Wait for the monsoon.
How long until a grafted mango fruits?
Usually within a few years of planting in the ground, far sooner than a seedling. Remove very early flowers.
Can I graft different mango varieties on one tree?
Yes, several varieties can be grafted on separate branches of one tree, using the same methods.
