How to Grow Custard Apple (Sharifa) at Home: Seed, Graft, Pots
Buy a grafted or budded plant and you can expect your first sharifa within one to two years; sow a seed from last winter’s fruit and you are usually waiting two to four years, often for smaller, more variable fruit. Custard apple (Sharifa, Sitaphal) is one of the easiest fruit trees for a hot, dry Pakistani or North Indian roof, as long as you never let its roots sit in water. Put simply, that is how to grow custard apple at home in our climate.
The short version
- Best start: a budded or grafted nursery plant; seed is fine if you are patient
- Years to fruit: grafted, often the next season; seedling, two to four years
- Pot: start in 40 to 50 litres (about 16 to 18 inches across), move to 70 to 100 litres (a half drum) by year three
- Sun: six hours or more of direct sun
- Plant: February to March, or July to August with the monsoon
- Verdict: plant it in the plains; maybe in Islamabad; skip in the frosty hills

Which propagation method actually works at home?
Seed is the method most home growers use, and it works. Purdue’s fruit reference notes sharifa seed stays viable for years, but germination can take a month or more, and soaking for a few days speeds it up. The catch is time and quality. A seedling is a genetic lottery: it may give fine fruit or small, seedy ones.
Budding is how nurseries in India multiply good varieties, and Purdue reports shield budding as the commercially workable method there, with grafted plants on Ramphal (Annona reticulata) rootstock flowering within months of planting out. Cuttings and layers root poorly and form a weak, shallow root system, so skip them. Air layering? Possible, rarely worth the bother.
| Method | Verdict | Why |
|---|---|---|
| Seed | Plant | Cheap, sprouts readily in warmth, fruit in two to four years, quality varies |
| Budded or grafted plant | Plant | Fastest fruit, known variety; look for the graft bump low on the stem |
| Grafting your own seedling | Maybe | Worth trying on a one year old seedling if you can get scion wood |
| Cuttings or air layering | Skip | Low success and shallow roots that sulk in drought |
Growing sharifa from seed, step by step
- Take seeds from a large, sweet fruit in October or November. Wash off the pulp and dry them in shade for a week.
- Store them in a paper envelope until late February, when nights stay above about 15°C.
- Soak the seeds in plain water for two to three days, changing the water daily.
- Sow 2 cm deep in small bags or 4 inch pots of half garden soil, half compost. Keep warm and just moist.
- Expect sprouts in three to six weeks. Do not give up at week two.
- Pot up the strongest seedling when it has four to six leaves, and move it to its 40 litre home before the monsoon.
What pot and soil mix does a custard apple need?
A wide, drained pot. Sharifa is shallow rooted and hates wet feet more than heat. Begin in 40 to 50 litres, then step up to a 70 to 100 litre container or a cut plastic drum with six or more holes. In the ground, give it the sunniest, best-drained corner you have.
Mix two parts garden soil, one part well rotted compost or gobar, and one part coarse sand or brick grit. Our potting mix ratio guide explains why cocopeat alone is too wet for a tree like this.
When to plant in Karachi, Multan, Lahore and the hills
| Zone | Plant | Watch for |
|---|---|---|
| Coastal humid (Karachi) | Feb to Mar, or Jul to Aug | Mealybug in humid months; good flowering humidity |
| Hot dry (Multan, Sukkur, Bahawalpur) | Feb to Mar | Flower drop in dry heat; mulch and evening misting help |
| Punjab plains (Lahore, Faisalabad, Delhi) | Feb to Mar, or Jul to Aug | Frosty nights in late Dec to Jan for young plants |
| Sub-humid (Islamabad, Peshawar) | Mar to Apr | Winter cold; keep pots against a south wall |
| Hills | Skip | Too cold for reliable fruit |
How much water in a 45°C summer, and in winter?
- March to May: water when the top 3 cm feels dry, about every two to three days in a pot.
- June heat (40 to 45°C): daily in pots, early morning, deep enough that a little drains out. A 5 cm mulch of dry leaves or straw saves a lot.
- Monsoon: check drainage after every downpour. Never leave a saucer full.
- December to February: sharifa drops most leaves and rests. Water once every seven to ten days, just enough to keep the soil from turning to dust. On frost nights in Lahore or Delhi, move pots under a shade or cover young plants with a cloth.
Feeding without burning the roots
Each February, scratch in two to three handfuls of compost and repeat in July. If you use a bought fertiliser, a balanced NPK in a small handful at the same times is enough for a potted tree; once flowers appear, a feed higher in potassium supports fruit. More nitrogen gives leaves, not sharifa.
The paintbrush trick for empty branches
Sharifa flowers are fussy: the female parts are ready before the male parts in the same flower, and dry air makes it worse, which is why Purdue notes old trees rarely carry many fruits without hand pollination. Between 7 and 9 am, use a soft paintbrush to collect pollen from a fully open, older flower (petals spread wide) and dab it inside a half open, younger flower. Ten minutes a morning in April to June can turn a fruitless tree into a bearing one.
Why is my custard apple plant not fruiting?
Usually one of four reasons: it is a young seedling (under three years), it gets under six hours of sun, the air is too dry at flowering, or it is overfed with nitrogen. Hand pollination fixes the third more often than any spray.
Yellow leaves, mealybugs and other problems
| Sign | Likely cause | First response |
|---|---|---|
| Yellow leaves in Nov to Jan | Normal winter leaf drop | Nothing; reduce water |
| Yellow leaves in summer, wet soil | Waterlogged roots | Fix drainage, water less |
| White cottony clumps, sticky leaves, black film | Mealybug or soft scale with sooty mould | Wipe off, hose down, mild soap spray; control ants |
| Dark spots on leaves and fruit | Anthracnose type fungus | Remove spotted parts, improve airflow |
| Fruit turns hard and black on the tree | Seed borer or fruit rot | Pick and bin infected fruit; bag fruit in cloth |
How do you know when to pick?
Fruit sets in early summer and is ready from about September to November in the plains. Pick when the gaps between the bumps turn creamy and the fruit gives slightly; it ripens in a day or two indoors.
Sharifa seeds and leaves are toxic if chewed and the seed powder irritates eyes badly, so keep loose seeds away from children and pets and wash hands after handling them. If you use any chemical pesticide, read the label, wear gloves and a mask, keep children and pets away until it dries, and respect the waiting period before picking. A large tree pot weighs well over 100 kg when wet: check that your roof slab can take it.
Grow it or skip it?
Plant it if you live in the plains, have a sunny roof or yard, and can wait a year or two. It is far easier than mango or chikoo in a pot. Skip it in the hills. For a first kitchen garden, start with quicker plants from our first five plants guide while the sharifa grows up.
Custard apple growing questions
How to grow custard apple at home?
Start with a grafted plant or soaked seed in a large, well drained pot in full sun. Water deeply in summer, very lightly in winter, feed compost twice a year, and hand pollinate flowers in early summer.
Can custard apple be grown in pots?
Yes, it is one of the better fruit trees for pots. Use at least a 70 litre container by year three, keep it pruned to about two metres, and repot or root prune every three years.
How long does a custard apple seed take to germinate?
Usually three to six weeks in warm weather. Old or unsoaked seed can take longer, so keep the soil warm and slightly moist and be patient.
What is the best time to plant custard apple in Pakistan?
February to March in most of the plains, or July to August with monsoon rain. In Islamabad and Peshawar wait until March or April when the cold has passed.
Will a seedling give the same fruit as the parent?
Not reliably. Seedlings vary, so the fruit may be smaller or seedier. A budded plant of a named variety is the way to get known fruit.
Why do custard apple flowers fall without fruit?
Mostly poor pollination in dry air. Hand pollinate in the morning, mulch the pot, and mist around the plant in the evening during flowering.
Should I prune my sharifa tree?
Yes, lightly in late winter before new growth. Remove dead and crossing branches and shorten long shoots; sharifa fruits on new season growth, so a light cut encourages it.
Does custard apple survive frost?
Mature trees take a light frost, but young plants get damaged. Cover them or move pots under shelter on frosty nights in late December and January.
Is Ramphal the same as sharifa?
No. Ramphal is a related Annona species often used as rootstock. Its fruit is less sweet, but it makes a sturdy base for grafting sharifa.
