Tuberose cultivation in polyhouse and hydroponics
Grow fragrant tuberose (rajnigandha) under a nethouse or polyhouse, from bulbs planted in cocopeat troughs fed by drip. Clean spikes and loose flowers for garlands, weddings and perfume, with a farm designed, built and supported by Kryzen.
Spikes in 3–4 months
One planting yields 2–3 years
Exact drip feeding
Why protected cultivation
Can tuberose be grown in a polyhouse?
Quick answer
Yes. Tuberose grows well under a nethouse or polyhouse from bulbs planted in cocopeat troughs or raised beds. Spikes come 3–4 months after planting, and one planting keeps flowering for 2–3 years.
A nethouse or polyhouse keeps heavy rain off the spikes, which causes spotting and rot. Insect net keeps out thrips and aphids, and clean cocopeat stops bulb rot and nematodes from soil.
| Point |  |  |  |
|---|---|---|---|
| Season | One warm season | Longer season | Longer season with steady feeding |
| Harvest | Spikes in season only | More spikes a year | Spikes through the year for 2–3 years |
| Flower quality | Spotted, rain-damaged florets | Cleaner spikes | Clean, fragrant spikes |
| Pests | Thrips, aphids and nematodes | Insect net and traps keep pressure low | Insect net and traps keep pressure low |
| Soil diseases | Bulb rot and nematodes build up in soil | Still a risk; soil disease builds up over cycles | None; clean cocopeat |
| Water and fertiliser | Flood irrigation; much is lost | Drip into soil; some is lost | Exact drip doses to every plant |
| Revenue per acre per cycle | ₹3–5 lakh | ₹5–8 lakh | ₹9–12 lakh |
| Setup cost | Low | Medium | Highest; see your quotation and subsidy |

Where it grows
Best growing systems for tuberose
Tuberose grows from bulbs and stays in the bed for 2–3 years. Deep cocopeat troughs or raised beds with drip suit it best.
Most usedTrough
Deep cocopeat troughs with drip; bulbs stay in place for 2–3 years.
Cocopeat grow bags
Deep cocopeat bags for smaller plantings.
Inside the right polyhouse
What to plant
Types of tuberose grown in polyhouses
Single types are used for loose flowers and perfume; double types are used for cut spikes.
Tuberose (rajnigandha)
Fragrant white spikes and loose flowers for garlands, weddings, temples and perfume.
Climate and feeding
Ideal growing conditions for tuberose
A polyhouse lets you hold these ranges for most of the year. Vents, shade nets, foggers or fan and pad cooling keep heat in check, and drip fertigation sets the feed. Values are from the Kryzen Plant Wiki.

| Factor | Ideal range for tuberose |
|---|---|
| Season | Flowers most in warm months |
| Growing temperature | 20–30 °C |
| Relative humidity | 60–80% |
| Feed TDS | About 1,000 ppm |
| Feed pH | 6.0–7.0 |
| Plant density | Rows 30 cm apart, bulbs 15–20 cm apart |

Plant protection
Common tuberose pests and diseases
A polyhouse with insect net, double doors and sticky traps keeps most problems out. Catch the rest early. See the Agronomy Wiki for full guides.
| Pest or disease | What you see | How to prevent it |
|---|---|---|
| Thrips | Streaked, deformed florets | Blue sticky traps, insect net |
| Aphids | Sticky, curled shoots | Insect net, yellow sticky traps |
| Root-knot nematodes | Stunted plants with knotted roots | Clean cocopeat, treated bulbs |
| Bulb rot | Yellow leaves and soft bulbs | Well-drained media, treated bulbs |
| Botrytis | Brown spots on florets | Lower humidity, pick on time |
Harvest and selling
