Ash Gourd (Petha/Kumbh)
Benincasa hispida
A heavy, long-duration warm-season vine with one trait that sets it apart from every other gourd on this site — leave the fruit on the vine until it is fully mature and its skin develops a thick, chalky-white wax coating, and it will keep for months at room temperature instead of days, which is exactly why ash gourd (petha, kumhda) is both the vegetable-market gourd that lasts longest in storage and the raw material for petha, the candied sweet.

Quick Summary
Ash gourd (petha, kumhda in Hindi, winter melon or wax gourd in English) is a warm-season climbing cucurbit grown across a wide belt of India — Uttar Pradesh, Punjab, Bihar, West Bengal, the north-eastern hill states, Odisha, Kerala and Tamil Nadu between them growing most of the crop. It is a long-duration vine compared with other gourds, typically taking four to five months from sowing to a fully mature fruit, and it is unusually heavy — a single mature fruit commonly weighs anywhere from 3 kg to well over 10 kg depending on variety.
The trait that defines ash gourd is its wax coating. As the fruit nears full maturity, its hairy green skin loses its fuzz and develops a thick, chalky, white waxy bloom — the reason it is also called wax gourd. That wax coating is a natural preservative: a fully mature, uninjured ash gourd can be stored at ordinary room temperature for several months, sometimes close to a year, far longer than any other gourd grown in India. This is also exactly why ash gourd, not any other cucurbit, is the base ingredient for petha, the translucent candied sweet particularly associated with Agra — the firm, low-moisture flesh of a mature fruit holds its shape through the sugar-syrup cooking process.
This changes the harvest logic compared with bottle gourd or bitter gourd, where the rule is always "pick young." Ash gourd grown for the vegetable market is cut somewhat earlier, while still tender enough to cook as a curry vegetable; but a crop grown for storage or for petha-making is deliberately left on the vine until the wax coating is fully formed and the rind has hardened — cutting it too early forfeits both the storage life and the firm texture the candy trade needs.
Field management otherwise follows the same pattern as other bower-grown cucurbits: a well-manured pit, an overhead trellis or enough ground space for the heavy vine to spread, steady moisture through the long flowering-to-fruiting period, and watching for the same fruit flies, beetles and mildews that trouble bottle gourd and bitter gourd.

Overview
Ash gourd (Benincasa hispida), known as petha or kumhda in Hindi and as wax gourd or winter melon in English, is a warm-season climbing cucurbit grown for its large, oblong-to-round fruit. It is eaten as a cooked vegetable while young and tender, and — once fully mature — processed into petha, the candied sweet, or stored whole for months as a genuinely long-keeping vegetable.
It is grown widely across India: Uttar Pradesh (especially around Agra, for the petha industry), Punjab, Bihar, West Bengal, the north-eastern hill states, Odisha, Kerala and Tamil Nadu all grow it commercially, in a summer crop sown January–March and a rainy-season crop sown June–July, similar to the sowing windows of bottle gourd and bitter gourd.
What sets ash gourd apart from every other gourd is the thick, chalky wax coating that develops on its skin as the fruit reaches full maturity. This coating gives a mature, undamaged fruit an exceptional shelf life — commonly several months at ordinary room temperature, sometimes close to a year — and it is also why ash gourd, uniquely among cucurbits, is the standard base for petha and other candied preparations. Because of this, the harvest decision differs from other gourds: fruit destined for the fresh-vegetable trade is cut somewhat earlier and tender, while fruit destined for storage or processing is deliberately left to mature fully and develop its wax coat before cutting.
Crop timeline, sowing to harvest
A quick visual map of the season — jump to any section below for the detail behind each stage.
- Day 0
Sowing
Soaked seed dibbled 2–3 per pit at wide spacing; summer crop January–March, rainy-season crop June–July.
- Day 6–15
Germination & seedling
Seedlings emerge and the red pumpkin beetle window opens; young plants need protection while small.
- Day 20–35
Vine growth & training
The heavy vine begins to run; it is either trained onto a strong bower or allowed to spread on the ground with enough space between pits.
- Day 40–60
Flowering
Large yellow flowers open and are insect-pollinated; female flowers carry a small fruit behind the petals.
- Day 65–90
Fruit development — vegetable-market fruit
Fruit for the fresh-vegetable trade is cut around this stage, while still tender enough for cooking as a curry vegetable.
- Day 120–150
Full maturity — storage and petha fruit
Fruit grown for storage or petha-making is left on the vine until the rind hardens and the characteristic white wax bloom fully forms, then cut with a length of stalk attached.

Grown here
Climate requirements
Because the fruit is deliberately left on the vine far longer than other gourds when grown for storage, protecting the ripening fruit from direct soil contact (a mat or straw layer underneath) matters more here than for a quickly-picked crop.
Ideal temperature
A hot-weather crop, best at 24–30°C. It grows poorly and germinates slowly below about 18°C, so the summer crop waits until the worst of the cold has passed. It has no frost tolerance.
Rainfall
The rainy-season crop runs largely on the monsoon but cannot stand waterlogging; the summer crop is grown entirely on irrigation.
Humidity
Moderate humidity suits growth; long humid, overcast spells favour downy and powdery mildew and slow the drying of dew on the leaves and developing fruit.
Sunlight
Full sun. A shaded vine grows leafy but sets and matures fruit poorly, and fruit left in dense shade develops a weaker wax coating.
Soil requirements
Ash gourd is a heavy feeder over an unusually long season — land well manured for the previous crop, with fresh compost at sowing, keeps the vine and its heavy fruit load going to full maturity.
Suitable soil
A deep, well-drained sandy loam to loam rich in organic matter suits ash gourd well. It tolerates a range of soils but does badly on heavy, waterlogging clay, especially given how long the crop stays in the ground.
pH range
Best at pH 6.0–7.5; it handles a fairly wide range but strongly acid or saline soils cut yield.
Drainage
Free drainage is essential, especially given the crop's long duration — a season of poor drainage has far more time to cause collar and root rot than in a quicker vegetable.
Organic matter
Responds strongly to well-rotted farmyard manure and neem cake worked into the pits before sowing, since the vine has to sustain very heavy fruit over a long season.
Land preparation
Same four steps whichever region you are in — only the timing shifts with the sowing window.
- 1
Plough and open pits or ridges
Plough two or three times to a fine tilth; dig pits about 30 × 30 × 30 cm at roughly 2 × 1.5 m spacing, or form ridges for a bower crop.
- 2
Mix in manure and basal fertiliser
Work well-rotted FYM and neem cake into each pit, with a basal dose of phosphorus and potash and part of the nitrogen.
- 3
Plan for the fruit's size and weight
Whether trained on a strong bower or left on the ground, allow generous space — a mature ash gourd is among the heaviest fruit grown on a home vine, and a weak trellis can collapse under a full crop load.
Seed information
How the main varieties compare, so you can pick by duration, yield, disease pressure or what you are growing for.
| Variety | Duration | Yield | Disease resistance | Best state | Suitable for |
|---|---|---|---|---|---|
A Tamil Nadu Agricultural University selection from a local Tamil Nadu type. Large, oblong-oval, ashy-coated fruit averaging around 6–7 kg, with good cooking quality and a long crop duration. | ~140–150 days to full maturity | 20–25 t/ha | No special resistance widely documented | Tamil Nadu | Standard large-fruited variety, cooking and processing |
A TNAU selection from a Coimbatore local type, notably shorter-duration and smaller-fruited than CO 1 — fruit weighing about 2–3 kg each — while giving a considerably higher yield. | ~120–130 days | ~34 t/ha | No special resistance widely documented | Tamil Nadu | Smaller-fruit market, quicker turnaround than CO 1 |
An ICAR-IIVR (Varanasi) release with a long vine (7.5–8 m), oblong fruit, thick white flesh (8.5–8.7 cm) and very high yield potential for an open-pollinated variety, at around 11–12 kg per fruit. | ~120 days | 23–24 t/ha (230–240 q/ha) | No special resistance widely documented | Uttar Pradesh, Bihar, eastern states | Large-fruited commercial crop, thick-fleshed for processing |
An IARI (New Delhi) release with oblong-to-ellipsoid fruit, a distinctive greenish-white rind and white flesh, each fruit weighing around 3 kg — smaller and more manageable than the largest named varieties, with good yield. | ~120 days | 23–25 t/ha | No special resistance widely documented | Northern plains | Fresh-vegetable market, manageable fruit size |
A Kerala Agricultural University release, known in southern growing tracts for high yield and substantial flesh thickness, well suited to Kerala's warm, humid growing conditions. | Comparable to other open-pollinated varieties (~110–130 days) | High; specific figure not consistently documented | No special resistance widely documented | Kerala | Southern humid-tropical conditions |
A private F1 hybrid from Mahyco, maturing in 110–120 days, with fruit that turns the characteristic white and waxy at full maturity. A commercially popular hybrid choice for growers wanting a heavier, more uniform yield than open-pollinated types. | 110–120 days | High (hybrid vigour); typically well above open-pollinated varieties | No special resistance widely documented | Widely sold across India | Commercial growers wanting hybrid yield and uniformity |
A private F1 hybrid from Namdhari Seeds bred for year-round cultivation, with round, green fruit reaching 22–26 cm and a comparatively short 80–85 day maturity for a high-yielding hybrid. | 80–85 days | High (hybrid vigour) | No special resistance widely documented | Widely sold across India | Quicker-turnaround hybrid, round-fruit market |
- Seed rate
- 2–2.5 kg/ha for open-pollinated varieties; about 1.5 kg/ha for F1 hybrids. On an acre that is roughly 0.8–1 kg of open-pollinated seed, or about 0.6 kg of hybrid.
- Certified seed
- Buy fresh seed of a named variety each season from a state seed corporation, an ICAR institute or a reputed company. Hybrid seed must be bought new every time. Decide at purchase whether the crop is aimed at the fresh-vegetable market (a smaller, quicker-maturing type) or at storage and petha-making (a large-fruited type known to develop a good wax coat), since this shapes the whole harvest plan.
- Spacing
- Pits or hills roughly 2 m between rows and 1–1.5 m within the row for a bower crop; wider on the flat. 2–3 seeds per pit, thinned to the best 1–2 plants.
- Seed treatment
- Soak seed for 24 hours to speed germination. Treat with thiram or carbendazim plus Trichoderma against damping-off and seedling rots.
Sowing guide
Do not sow the summer crop into cold soil — germination is poor and slow. Wait until night temperatures are reliably above about 18°C.
- Best time
- Northern plains: January to March for the summer crop (after frost risk passes) and June–July for the rainy-season crop. South and coast: a longer window, broadly similar to other warm-season cucurbits in the region.
- Row spacing
- 2 m between rows/pits
- Plant spacing
- 1–1.5 m between hills
- Sowing depth
- 2–3 cm
- Method
- Dibble 2–3 soaked seeds per pit into a well-manured hill, thin to the best 1–2 plants, and train the vine onto a strong bower or allow it to spread on the flat with generous space.
Fertilizer schedule
A split dose beats one large dose applied at sowing — nitrogen especially is lost to the air and to leaching if it all goes in on day one.
- 1
Basal (at sowing/planting)
Day 0
Well-rotted FYM and neem cake in the pits, plus a basal dose of about 25–30 kg N, 60–70 kg P₂O₅ and 60–70 kg K₂O per hectare.
- 2
First top-dressing
25–30 days (vine growth)
About a third of the remaining nitrogen as the vine begins to run, lightly worked in around the hill.
- 3
Second and later top-dressings
From flowering through fruit development
The rest of the nitrogen split through flowering and fruit development — given the crop's unusually long duration and heavy fruit, an extra split dose partway through fruit swelling helps carry the vine to full maturity.
Irrigation schedule
1. Sowing to establishment
Day 0–20
Irrigate the basin before dibbling seed, then keep the bed moist through germination and early growth.
2. Vine growth to flowering
Day 20–60
Water roughly once a week, keeping the soil moist but not wet.
3. Fruit development to maturity
Day 60 to harvest
The critical period, made longer here than in other gourds by ash gourd's extended time on the vine — irrigate regularly so a very large, heavy fruit fills out fully, tapering off as fruit approaches full maturity and the wax coat sets.
Critical stages
- Flowering and fruit set
- The long fruit-development period through to full maturity
Water-saving tips
- Drip irrigation suits this long-duration crop well, giving steady moisture over months rather than the repeated flood-irrigation a furrow system would need.
- A mulch under the ground-trailing fruit conserves soil moisture, suppresses weeds, and keeps the developing wax coat clean.
- Ease off irrigation as fruit nears full maturity for storage — a drier finish helps the rind harden and the wax coating set properly.
Weed management
Common weeds
Organic control
- Hand-weeding in the first six to eight weeks, before the vine covers the ground or bower.
- A straw or plastic mulch suppresses weeds, saves water and — importantly for this crop — keeps fruit clean and off wet soil through its long time on the vine.
- On a bower, the ground beneath can be weeded or mulched through the whole long season, which a ground-trailing crop makes harder.
Chemical control
- A pre-emergence herbicide cleared for cucurbits right after sowing, followed by hand-weeding, is standard on larger areas.
- Confirm product, dose and pre-harvest interval with your local KVK.
Nutrient deficiency identification
What a shortage of each nutrient actually looks like on the plant, so you can tell a deficiency apart from a disease before you spray the wrong thing.
Nitrogen
Visible symptom
Pale, small, yellowing older leaves and weak vine growth, showing up as reduced flowering partway through this long-duration crop.
Potassium
Visible symptom
Scorched, browning margins on older leaves and poorly filled, smaller fruit that does not develop a good wax coat.
Boron
Visible symptom
Corky patches or cracks on the fruit and poor fruit set, more likely to matter here given how long the fruit stays on the vine.
Diseases to watch for
Symptoms, likely cause and what actually treats it — not just a spray name.
Downy mildew
- Symptoms
- Angular yellow patches on the upper leaf surface bounded by the veins, with a fine grey-purple mould underneath in humid weather; leaves brown and die from the base of the vine upward.
- Cause
- The oomycete Pseudoperonospora cubensis, favoured by cool nights, dew and long leaf wetness in the rainy season.
- Treatment
- A protective mancozeb spray, or a systemic downy-mildew fungicide once it appears, repeated at 8–10 day intervals in wet weather.
- Prevention
- Grow on a bower for airflow, avoid dense planting, use drip not overhead water, and destroy crop residue after harvest.
Powdery mildew
- Symptoms
- White powdery patches on the upper leaf surface and stems, spreading to whole leaves that then yellow and dry; worst in warm dry weather with cool nights.
- Cause
- Fungi in the Podosphaera/Erysiphe group, spread by wind-borne spores and not needing free water.
- Treatment
- Wettable sulphur or a recommended fungicide at first sign.
- Prevention
- Full sun and open spacing, balanced nitrogen, and removing the first affected leaves.
Anthracnose
- Symptoms
- Round, water-soaked to brown spots with dark margins on leaves and sunken, pinkish-oozing circular spots on the fruit that can develop during its long time on the vine.
- Cause
- The fungus Colletotrichum, seed- and residue-borne, spread by rain-splash in warm, wet weather.
- Treatment
- A protective mancozeb or chlorothalonil spray from the first spots, repeated in wet weather; remove and destroy affected fruit.
- Prevention
- Clean, treated seed; rotation away from cucurbits; wider spacing and a bower for airflow; and keeping ripening fruit off wet ground.
Mosaic virus
- Symptoms
- Mottled light-and-dark green, puckered, distorted young leaves and small, blotchy, misshapen fruit that cannot be sold or stored.
- Cause
- Aphid-borne cucurbit mosaic viruses, spread within minutes of an aphid probing a leaf.
- Treatment
- No cure. Rogue out infected plants early before aphids spread the virus further.
- Prevention
- Clean seed, early aphid control, removal of weed hosts, and a reflective mulch to deter aphids.
Pests to watch for
What to look for before the damage is visible, and organic options before you reach for a chemical.
Melon fruit fly
- Identification
- Brownish flies larger than a housefly around the vines; young fruit with tiny sting marks and oozing spots that go soft and drop, with white maggots and a foul rot inside when cut.
- Damage
- A serious pest on young, tender fruit before the rind hardens; once the rind has fully hardened and the wax coat has set, mature fruit is considerably more resistant to stings.
- Organic control
- Cue-lure or pheromone traps from first flowering; a protein-bait splash on the leaves; picking and destroying stung and fallen fruit daily.
- Chemical control
- Prefer bait sprays to cover sprays; if a cover spray is needed, use a CIB&RC-registered insecticide for cucurbit fruit fly and observe the pre-harvest interval.
Red pumpkin beetle
- Identification
- Small bright orange-red beetles on the seedlings that fly off when disturbed; round holes bitten in the cotyledons and young leaves; whitish grubs in the soil damage roots.
- Damage
- The main pest of the seedling stage — a swarm can destroy the stand at the early-leaf stage and force a resowing.
- Organic control
- Sow a little extra seed as insurance, cover seedlings with a net, handpick beetles at dawn, dust wood ash or spray neem.
- Chemical control
- A recommended insecticide for cucurbits at the seedling stage only; the established vine tolerates the beetle well.
Epilachna beetle
- Identification
- Rounded dull-orange beetles with black spots and spiny yellow grubs on the leaf undersides, scraping the leaf surface into a papery lace.
- Damage
- Heavy attack skeletonises foliage, cuts photosynthesis, and — given this crop's long duration — has more time to compound its damage than on a quicker vegetable.
- Organic control
- Handpick beetles, grubs and egg clusters from leaf undersides, and spray neem.
- Chemical control
- A recommended insecticide directed at leaf undersides only when defoliation is spreading.
Aphids and whitefly
- Identification
- Colonies of small soft-bodied insects on shoot tips and leaf undersides, with sticky honeydew, sooty mould and attendant ants.
- Damage
- Sap loss curls and stunts shoots, but the bigger threat is virus spread — a few insects can seed a field with mosaic virus.
- Organic control
- Neem sprays, strong water jets, yellow sticky traps, and conserving natural enemies.
- Chemical control
- A recommended systemic insecticide only when populations are heavy and virus pressure is high.
Common mistakes to avoid
The mistakes that cost growers the most, ranked by how often they show up in the field — not in the order you might expect.
- 1
Cutting storage- or petha-bound fruit too early.
Why it hurts
Without a fully formed wax coating and a hardened rind, the fruit neither stores for months nor holds up through the petha-making process. If the fruit is meant for storage or processing, leave it on the vine until fully mature.
- 2
Treating ash gourd like a quick-picked gourd such as bottle gourd.
Why it hurts
Ash gourd's much longer duration means fertiliser, water and pest management all need to be sustained for months rather than weeks — cutting the crop programme short partway through starves the vine before the heaviest fruit growth is done.
- 3
Sowing the summer crop into cold soil.
Why it hurts
Seed germinates poorly and slowly in cold ground. Wait until night temperatures are reliably above about 18°C.
- 4
Ignoring drainage on a crop that stays in the ground for months.
Why it hurts
Poor drainage has far longer to cause collar and root rot in ash gourd's long season than in a quicker-maturing gourd. Plant on ridges or raised hills and keep water moving.
- 5
Leaving mature fruit directly on wet soil.
Why it hurts
Ground contact through months of growth invites rot at the point of contact even on an otherwise sound, well-waxed fruit. A straw or mat layer under ground-trailing fruit prevents this.
- 6
Under-building the trellis for a bower crop.
Why it hurts
A mature ash gourd is among the heaviest fruit grown on a garden vine — a flimsy bower can collapse under a full crop load. Build for the weight the crop will actually carry.
Harvesting
For the fresh-vegetable market: cut around 65–90 days, while the fruit is still tender enough to cook as a curry vegetable and before the rind hardens fully. For storage or petha-making: leave the fruit on the vine until it reaches full maturity, typically 120–150 days, by which point the rind has hardened and the characteristic thick white wax coating has fully formed. Cut with a length of stalk attached and handle gently — bruised or cut fruit loses its long storage life.
Signs it is ready
- For vegetable use: fruit still firm but the skin not yet fully hardened or waxed
- For storage/petha use: skin covered in a thick, chalky white wax bloom, hairs gone, rind hard when tapped
- A length of stalk still attached at cutting
- No visible cracks, cuts or insect-sting marks on the rind
Tools
- A sharp knife or pruning saw — the mature stalk is thick and tough
- A padded cart or sturdy crate — mature fruit is very heavy
- Clean, dry storage space out of direct sun for fruit destined for long keeping
Expected yield
About 20–35 t/ha for an open-pollinated crop and 80–90 t/ha for a well-managed hybrid. On an acre that is roughly 80–140 quintals for open-pollinated varieties, considerably more for hybrids.
Post-harvest & storage
Storage
A fully mature, uninjured, well-waxed ash gourd is exceptional among vegetables for its keeping quality — commonly several months at ordinary room temperature in a dry, ventilated spot out of direct sun, and reportedly close to a year under good conditions. Fruit cut early for the vegetable market, without the full wax coat, keeps only days to a couple of weeks like other gourds.
Packaging
Handle mature fruit carefully to avoid bruising or cutting the wax coating, which is what protects it; store on a raised, dry surface rather than directly on damp ground.
Transportation
Mature fruit tolerates a long haul well given its natural keeping quality; young vegetable-market fruit should move to market promptly like other gourds.
Shelf life
Days to two weeks for young vegetable-market fruit; commonly several months, sometimes close to a year, for a fully mature, well-waxed fruit stored under dry, ventilated conditions.

Frequently asked questions
Why does ash gourd keep so much longer than other gourds?
A fully mature ash gourd develops a thick, chalky wax coating on its skin as it ripens, which seals the fruit and slows moisture loss and rot far more effectively than the thinner skin of a bottle gourd or bitter gourd. A mature, uninjured fruit commonly keeps for several months at room temperature, sometimes close to a year — but only if it was left on the vine long enough to develop that wax coat fully before cutting.
Should I pick ash gourd young like bottle gourd, or let it mature fully?
It depends on the use. For the fresh-vegetable market, cut it somewhat earlier — around 65–90 days — while still tender enough to cook. But if the fruit is meant for long storage or for making petha, leave it on the vine until full maturity (roughly 120–150 days), by which point the rind has hardened and the wax coating has fully formed. Cutting it early for these uses forfeits both the storage life and the firm texture petha-making needs.
What is petha made from, and why does it need ash gourd specifically?
Petha is a translucent candied sweet, particularly associated with Agra, made by cooking chunks of mature ash gourd in sugar syrup. Ash gourd is used because its firm, low-moisture flesh holds its shape through the syrup-cooking process rather than turning mushy, which most other gourds would do.
Why is my ash gourd vine growing well but not fruiting much?
Check for adequate pollination — like other cucurbits, ash gourd needs insect activity to move pollen from male to female flowers, so heavy pesticide use during flowering can hurt bee visits. Also check nitrogen levels: excess nitrogen pushes leafy growth at the expense of flowering. Given how long this crop stays in the field, sustaining a balanced fertiliser programme through the whole season matters more than for a quicker gourd.
How much space does ash gourd need?
More than most gourds, both because the vine is vigorous and because the mature fruit is very heavy — commonly 3 kg to over 10 kg depending on variety. Space hills roughly 2 m between rows and 1–1.5 m within the row, and build any bower strong enough to carry the full weight of a mature crop.
Does ash gourd have an MSP or a mandi price?
There is no MSP for ash gourd. It trades on Agmarknet under the commodity name "Ashgourd", with genuine daily price and arrival records from markets in producing states including Tamil Nadu and Kerala.
