How to Grow Cardamom in India:
The Complete State-by-State Guide
Everything you need to know about cardamom cultivation in India — from the Western Ghats to your backyard — with KAU-verified varieties, a planting calendar and a region-fit calculator.
To grow cardamom in India, plant in Kerala, Karnataka or Tamil Nadu at 600–1,200 m altitude with annual rainfall of 1,500–2,500 mm, well-drained loamy soil at pH 5.5–6.5, and 50–60% filtered shade. Transplant rhizome-raised seedlings in June–July; first harvest arrives in 2–3 years.
India: The Original Home of the Queen of Spices
Cardamom (Elettaria cardamomum) didn’t just originate in India — it evolved in the Western Ghats. No other country grows it on terrain this well-suited, at this scale.
The entire Western Ghats mountain range — a UNESCO biodiversity hotspot — is sometimes called the Cardamom Hills precisely because of how naturally the crop thrives there. Kerala alone accounts for over 56% of the total cultivated area, with Idukki district at the very heart of India’s cardamom trade. The world’s largest cardamom auction market sits in Kumily, near Munnar.
The Three Cardamom States: What Makes Each Unique
Growing conditions, preferred varieties and farming practices differ meaningfully between Kerala, Karnataka and Tamil Nadu.
The Idukki district — specifically the talukas of Udumbanchola, Peermade and Devikulam — dominates Indian cardamom output. Forest loam soils, well-distributed south-west monsoon rainfall and elevations of 900–1,200 m create near-perfect conditions. Kerala recorded an average yield of 543 kg/ha in 2021–22, the highest among the three states.
Best varieties: Vazhukka (natural hybrid), ICRI-1, ICRI-2, PV-1 (all KAU-recommended)
Planting season: June–July with onset of south-west monsoon
🌧️ Rainfall: 1,800–3,500 mm/yrThe Coorg (Kodagu) region and parts of Hassan and Chikmagalur districts are Karnataka’s cardamom heartland. The Malabar cultivar — with its distinctive prostrate (ground-creeping) panicle — dominates here. Nursery sowing in Karnataka happens earlier, in September–October, due to a slightly different monsoon pattern.
Best varieties: Malabar Selection-1 (CCS-1), Mudigree-1, SKP-14
Planting season: June–July; nursery sowing September–October
🏔️ Altitude: 700–1,100 mThe Nilgiri Hills and the area around Bodinayakanur (Theni district) — officially called the Cardamom City of Tamil Nadu — are the prime growing regions. Cool temperatures, rich laterite soils and abundant Nilgiri rainfall support good quality Mysore-type cardamom. Area is smaller than the other two states but quality is consistently high.
Best varieties: Mysore type (erect panicle), ICRI-2
Planting season: June–July; nursery sowing November–January
🌡️ Temp: 15–28°C (ideal)What About North India & North-East?
Green cardamom (Elettaria cardamomum) cannot be commercially grown outdoors in most of North India — winters are too cold and summers too dry. However, Sikkim and parts of North-East India (Arunachal Pradesh, Meghalaya) are excellent for black cardamom (Amomum subulatum), a related but distinct spice. Green cardamom in North India is only viable in pots indoors or a climate-controlled greenhouse. See our indoor growing guide for details.

Meeting these benchmarks is non-negotiable — deviate too far and yield drops sharply. Source: KAU, IndiaAgroNet & Spices Board India.
| Factor | Ideal Range | Tolerance Limit | Notes |
|---|---|---|---|
| Altitude | 600–1,200 m AMSL | Up to 1,400 m | Below 500 m heat stress occurs; above 1,400 m frost risk rises |
| Temperature | 18–30°C | 10–35°C | Frost kills plants; steady warmth preferred over extremes |
| Annual Rainfall | 1,500–2,500 mm | Up to 4,000 mm | Well-distributed critical; summer showers Feb–Apr initiate panicles |
| Humidity | 60–80% | Min 55% | Below 50% causes leaf browning and poor pod set |
| Shade | 50–60% filtered | 40–70% | Excess shade reduces yield; full sun scorches foliage |
| Soil pH | 5.5–6.5 | 5.0–6.8 | Forest loam richest in humus; laterite & clay loam also work |
| Soil type | Deep loamy / forest loam | Laterite, clay loam | Sandy soil unsuitable; waterlogging causes Phytophthora root rot |
| Drainage | Free-draining | — | Use contour bunds on slopes; terrace farming in steep areas |
Soil Expert Note (KAU)
Deep black loam with high humus content — as found in forest clearings of the Western Ghats — is the gold standard for cardamom. A pH below 5.0 requires lime amendment; above 6.8, sulphur applications are needed. Never plant in sandy or waterlogged soil as Phytophthora nicotianae root rot spreads rapidly in poorly drained conditions (NIPHM confirmed).

Recommended Varieties for Indian Growers
Choose a variety matched to your state and elevation for best yield. All KAU and Spices Board India recommended selections.
The most widely grown variety in Kerala — a natural cross between Malabar and Mysore types. Erect panicles, high pod count per clump and good aromatic oil content.
Released by the Indian Cardamom Research Institute, Myladumpara. High-yielding, early bearing and resistant to katte (mosaic) virus. Popular with commercial growers in Idukki.
Widely adaptable across Kerala, Karnataka and Tamil Nadu. Known for uniform capsule size and high essential oil content (α-terpinyl acetate dominant), fetching premium auction prices.
Developed at the Cardamom Research Station, Pampadumpara (KAU). Prostrate panicle typical of Malabar type. Capsules mature in 110 days; 17 seeds per capsule with 6.8% essential oil. Suited to Karnataka’s slightly drier conditions.
Performs well in the high-rainfall talukas of Idukki. Produces large capsules with uniform green colour — important for premium export-grade grading at Kumily market.
A Coorg regional selection suited to the slightly lower-rainfall conditions of Karnataka’s cardamom belt. Good drought tolerance relative to Kerala varieties; commonly intercropped with coffee in Coorg estates.
Never Plant Katte-Infected Material
Katte (cardamom mosaic virus) is transmitted through infected rhizomes. KAU confirms there is no cure — infected plants must be removed and destroyed immediately. Always source planting material from certified, disease-free nurseries registered with the Spices Board India.

Step-by-Step: How to Plant Cardamom in India
Follow the KAU and Spices Board India recommended process for maximum establishment success.
Prepare the Nursery Bed (12–18 months before field planting)
Select a nursery site near a water source with loamy, humus-rich soil. Create shaded raised beds. Sow seeds or plant rhizome divisions at 20 cm spacing. In Kerala and Tamil Nadu, sow November–January; in Karnataka, September–October. Germination begins around 30 days after sowing. Erect an overhead pandal (shade frame) immediately. Water regularly — keep moist, never waterlogged.
Secondary Nursery Transfer (After 3–4 months)
When seedlings have 3–4 leaves, transfer to secondary nursery beds at 1:10 ratio (one primary bed fills ten secondary beds). Apply farm yard manure (FYM) before transplanting. Mulch immediately after planting. Continue overhead shade. In Kerala and Tamil Nadu, this typically happens March–May; seedlings are ready for the main field after one full year in secondary nursery.
Land Preparation & Pit Digging
Plough or dig the main field 3–4 times for fine tilth. Remove all weeds, rocks and debris. On slopes, create contour bunds to prevent erosion and waterlogging. In hilly terrain, terrace farming is recommended. Dig planting pits of 45×45×30 cm (or 60×60×35 cm for larger varieties). Fill each pit with a mix of compost and top soil. Apply 12–15 tonnes of FYM per hectare during the final soil preparation round. Target spacing: 2×2 metres (or 2×1 m on contours).
Field Transplanting (June–July)
Transplant with the onset of the south-west monsoon — cloudy days with light drizzle are ideal. Uproot seedlings carefully from the nursery, trim overgrown roots and separate clumps. Plant so that the tallest tiller stands in the centre with smaller tillers on the sides. Cover roots up to the collar region only — do not bury the growing tip. Water gently after planting. Provide shade for the first two weeks post-transplanting.
Shade Management (Ongoing)
Cardamom requires 50–60% filtered sunlight. Natural forest canopy is ideal; planted shade trees (Silver Oak, Erythrina) are common in commercial plantations. Regulate shade before the monsoon (April–May) by pruning the upper canopy so sufficient light reaches plants during the growth flush. Excess shade is as harmful as full sun — it reduces flowering and pod set.
Fertiliser Application
For irrigated, high-yielding plantations (above 100 kg/ha), KAU recommends 75 kg N + 75 kg P₂O₅ + 150 kg K₂O per hectare annually. Split application: first dose at monsoon onset, second during mid-season growth flush. For rainfed gardens, a lighter dose of 30:60:30 kg N:P:K per hectare is standard. Supplement with 5 kg organic compost or cattle manure per clump. Summer showers in February–April are critical for panicle initiation — ensure fertiliser has been applied before this window.
Irrigation (Dry Season)
During the dry season (February–May), irrigate every 7–10 days. Drip irrigation is the recommended method — it maintains consistent soil moisture without waterlogging and reduces the labour cost associated with flood or furrow irrigation. Cardamom is extremely sensitive to drought stress: even a 3-week dry period can abort developing pods and reduce yield significantly.
Trashing & Earthing Up (Annual)
Trashing — the removal of old, drying or diseased shoots — should be done once per year at monsoon onset under rainfed conditions, or 2–3 times per year in irrigated, high-density plantations. After the monsoon, earth up the base of each clump with a thin layer of fresh, fertile humus-rich soil, covering the collar region. This encourages new tiller formation and maintains soil structure around the root zone.

Ongoing Care for Indian Cardamom Plants
Once established, cardamom needs consistent care to maintain peak yield across its 15+ year productive life.
Watering
Every 7–10 days during dry months. Drip irrigation preferred. Never allow standing water — waterlogged roots develop Phytophthora rot within days.
Shade Control
Maintain 50–60% filtered light. Prune shade trees before monsoon (April–May) so the flush of new growth gets adequate light. Never go below 40% shade.
Trashing
Remove old, dry shoots once at monsoon onset (rainfed) or 2–3 times per year (irrigated). Improves airflow, reducing fungal disease pressure.
Mulching
Apply 5–7 cm organic mulch (dry leaves, paddy straw) around each clump. Retains moisture, suppresses weeds and slowly feeds the soil as it decomposes.
Pest Monitoring
Watch for thrips (Sciothrips cardamomi) on developing panicles. Also monitor for rhizome weevil and cardamom shoot fly. Early detection cuts yield loss by 60–70%.
Disease Watch
Katte (mosaic) virus: remove infected plants immediately — no cure. Phytophthora root rot: improve drainage and treat with copper-based fungicide at first sign. Rhizome rot: use Trichoderma-based biocontrol.
Harvest, Yield & Post-Harvest Drying
Getting the harvest and drying right determines the final grade — and the price you achieve at Kumily or your state auction market.
Cardamom is harvested by hand, picking individual ripe green capsules as they mature. The main harvest window runs September–February. Because pods on a single panicle ripen unevenly, experienced harvesters make repeat rounds every 25–30 days through the season. Commercial plantations with 400–450 plants per acre can yield 500–750 kg of dry cardamom annually at peak productivity (years 5–8).
| Method | Drying Duration | Quality Outcome | Notes |
|---|---|---|---|
| Traditional sun drying | 7–10 days | Yellow/light brown pods | Low-cost; dependent on weather; lower auction grade |
| Mechanical flue-curing | 24–36 hours | Premium green pods | Temperature controlled at 40–50°C; best colour retention |
| ICRI Curing Chamber | 18–24 hours | Premium green pods | ICRI-developed model; widely used in Idukki commercial farms |
Dry Recovery Rate Matters
The CCS-1 variety has a documented dry recovery rate of 19.9% — meaning roughly 5 kg of fresh green capsules yields 1 kg of dry marketable cardamom. Keep this ratio in mind when projecting income: a field yielding 4,000 kg fresh capsules produces approximately 800 kg dry, which is more realistically valued for auction.
Growing Cardamom at Home in India
Not everyone has a hectare in Idukki. Here’s how to successfully grow elaichi at home — in a pot, on a balcony or in a garden — anywhere in India.
Who Can Grow Cardamom at Home?
If you live in Kerala, Karnataka, Tamil Nadu or the Western Ghats foothills, you can grow cardamom directly in your garden provided you have a partly shaded spot. In hot plains cities (Delhi, Mumbai, Ahmedabad), cardamom can be grown in large pots (40+ litres) indoors near a bright window, or on a shaded balcony — but it will not produce pods commercially. It still makes a beautiful, fragrant houseplant.
Pot Size
Minimum 40-litre container (e.g. a large terracotta or fabric pot). Cardamom has a spreading rhizome system — it needs width more than depth. Repot annually until the plant fills its container.
Potting Mix
60% red/loamy garden soil + 30% well-composted organic matter + 10% coarse sand or perlite for drainage. Target pH 5.5–6.5. Never use heavy clay soil alone.
Light
Bright indirect light — east-facing window or a shaded south balcony. Avoid direct afternoon sun. Indoors in North India, a north or east window with occasional supplemental light works well.
Watering at Home
Water when the top 2 cm of soil feels dry. In hot dry climates, mist leaves daily to maintain 60%+ humidity. Use a humidity tray with pebbles and water under the pot.
