Dutch rose (long-stemmed cut rose) works in India only under a naturally ventilated polyhouse, in places with mild days and cool nights such as the Bengaluru and Hosur belt, the Nilgiris and the Pune and Nashik region. It needs a structure, drip fertigation, daily crop handling and a market that pays per stem, so it suits growers who can invest and manage it closely, not casual planters.
It is different from the desi rose grown in open fields for garlands and rose water. Open-field roses are sold by weight; cut roses are graded by stem length, bud size and colour and sold by the stem or bunch of 20.
Where it grows in India
- Main belts: Karnataka (Bengaluru region) is the largest cut rose state, followed by West Bengal and Maharashtra. In Tamil Nadu the polyhouse belt covers Hosur, Krishnagiri, Kodaikanal, Yercaud and the Kolli Hills.
- Temperature: TNAU gives 26 °C by day and 15 °C by night as ideal for rose, with at least 6 hours of bright sun. Hot plains summers need fogging, shade nets and ventilation, or stems turn short and buds open fast.
- Soil: well-drained sandy loam with pH 6 to 7 (TNAU). Raised beds with drip keep roots out of standing water.
- Market access: flowers are perishable, so a farm should be within a night's truck or a cold-chain run of a flower market or exporter.
Varieties and planting material
| Variety | Released by | Traits | Suited to |
|---|---|---|---|
| Arka Swadesh | ICAR-IIHR, Bengaluru | Red, medium-sized flower, shining foliage, stalk 65 to 70 cm, 145 stalks per sq m a year, keeps 6 days after harvest | Polyhouse cut flower production |
| Arka Ivory | ICAR-IIHR, Bengaluru | Creamish white, long flower stalk, moderately resistant to mites | Protected cultivation |
- Most premium Dutch and other European hybrid tea cultivars are patented and imported. Plants are budded or grafted on a rootstock and sold by licensed nurseries. Buy only from an accredited nursery with the variety name and invoice, and ask the buyer which colours and stem lengths are in demand before choosing.
- Indian varieties such as the IIHR releases give a cheaper option with no royalty, but check whether your buyers accept them.
Spacing and planting
- The NHB cost norms for cut rose assume 8 plants per sq m of bed. Another Indian production note gives 20 x 30 cm spacing, which is about 8 to 10 plants per sq m.
- One acre has 4,047 sq m (1 hectare = 10,000 sq m). Paths and service areas take part of the structure, so plants per acre of polyhouse are lower than 8 x 4,047. Work out the count from your bed layout.
- Use raised beds with well-rotted FYM and drip lines. A soil and water test before planting is worth the cost, because high salts or lime hurt roses.
Nutrition, irrigation and crop handling
- TNAU manuring for cut rose: 10 kg FYM and 8:8:16 g of N, P and K per plant after each pruning, repeated at three-month intervals. TNAU also notes a foliar spray of 20 g MnSO4, 15 g MgSO4, 10 g FeSO4 and 5 g borax per litre of water for brighter flowers. That schedule is for field-grown rose. Under a polyhouse the nutrients go through the drip, and the schedule should follow a soil and leaf test, so ask your KVK or the nursery's agronomist.
- Irrigation: frequent small drip doses keep the root zone moist. Overwatering causes root rot and encourages mildew.
- Training: bending weak shoots builds the plant frame and gives more basal breaks, and early pinching strengthens plants. Side buds are removed (disbudding) so one bud develops on each stem.
- Timeline: TNAU records flowering about 45 days after pruning in open-field rose; polyhouse crop cycles vary by variety and season.
Pests and diseases
- Thrips (Scirtothrips dorsalis) are the most damaging rose pest: a published study cites damage of 28 to 95% in unprotected crops. In Bengaluru trials under polyhouse and open field, neem seed kernel extract (5%) cut thrips by 64 to 88%, and spinosad, clothianidin and a garlic-based product also worked. Rotate products to avoid resistance.
- Spider mites rise in hot, dry spells; keep humidity up and wash leaves with water spray. Aphids, whitefly and scale also occur.
- Diseases: powdery mildew, downy mildew, botrytis (grey mould), black spot and die-back after pruning. Ventilate to cut humidity, remove infected leaves and prune cleanly.
- Follow the label and your KVK's advice for any chemical.
Harvest and yield
- Cut early morning with a sharp, clean knife at the tight bud stage with colour showing for distant markets; the bud can be slightly looser for a local market. Put stems in clean water at once and cool them.
- Stems of 45 to 60 cm are commonly the premium grade range cited by Indian growers; Arka Swadesh stalks average 65 to 70 cm.
- Yield: IIHR reports 145 stalks per sq m a year for Arka Swadesh. Production notes quote 150 to 300 stems per sq m for good polyhouse roses, but the higher figures are for the best imported cultivars with expert management. Plan on the lower end for the first two years.
- First flowers come a few months after planting; full production follows over the first year.
💡 Tip: Before building, ask two or three florists, exporters or the wholesale market for the price they pay by grade across the year, including the Valentine's Day and wedding peaks and the monsoon lows. Build the plan on the average price, not the peak.
Cost and returns
- Structure: the NHB cost norms were last revised in 2008 and allowed ₹500 to ₹750 per sq m including drip, depending on the structure type. Today's costs are much higher; get written quotes from approved suppliers and your state horticulture department.
- No reliable single profit figure exists. Cost depends on the structure, imported plants and labour, and price depends on grade and season.
- Revenue arithmetic (illustration only): 1,000 sq m of structure with about 700 sq m of bed at 145 stems per sq m gives roughly 101,500 stems a year. At an average farm-gate price of ₹4, ₹6 or ₹8 per stem, gross is about ₹4.1 lakh, ₹6.1 lakh or ₹8.1 lakh. The price figures are assumptions, not market data; replace them with quotes from your buyer.
- Labour for pruning, bending, harvest and grading runs through the year and is a major running cost, along with power, water treatment, packing and transport.
Market, risks and support
- Buyers include wholesale flower markets, florists and event decorators, and exporters. Roses are perishable, so a cold room or insulated transport matters.
- Prices swing with season and the arrival of stems from other growers.
- Check polyhouse subsidy and subsidy finder for current MIDH support. Subsidy rates and eligible costs differ by state and no current rate is quoted here. See drip irrigation, KCC for loans and FPO for group marketing.
