Why protected cultivation
Can carnation be grown in a polyhouse?
Quick answer
Yes. Carnation grows well in a polyhouse, mostly in cool and mild regions. Rooted cuttings are planted in cocopeat troughs or raised beds, held up by layers of net and fed by drip. Picking starts 4–5 months after planting and goes on for 8–10 months.
A polyhouse keeps rain off, which causes stem rot and petal spots. Support nets keep stems straight, insect net keeps out thrips and mites, and drip in clean cocopeat stops Fusarium wilt from soil.
| Point |  |  |  |
|---|---|---|---|
| Season | One cool season | Longer season | Longer season, with cooling in warm months |
| Harvest | Short picking period | Longer picking period | Picking for 8–10 months |
| Flower quality | Bent stems, split flowers | Straighter stems | Straight stems with full, clean flowers |
| Pests | Thrips, mites and aphids | Insect net and traps keep pressure low | Insect net and traps keep pressure low |
| Soil diseases | Fusarium wilt builds 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 | ₹2–5 lakh | ₹6–10 lakh | ₹3–9 lakh a month |
| Setup cost | Low | Medium | Highest; see your quotation and subsidy |

Where it grows
Best growing systems for carnation
Carnation is planted close together and needs support nets to keep stems straight. Cocopeat troughs or raised beds with drip suit it best.
Most usedTrough
Cocopeat troughs with drip and support nets; easy to keep the root zone clean.
Cocopeat grow bags
Cocopeat grow bags for smaller plantings.

What to plant
Types of carnation grown in polyhouses
Standard carnations carry one large flower per stem; spray carnations carry several smaller flowers.
Carnation
Long-lasting frilled flowers in standard and spray types for florists, bouquets and events.
Climate and feeding
Ideal growing conditions for carnation
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.
The Kryzen Plant Wiki on alpha.kryzen.com, prepared by an experienced agronomist with more than 35 years of work and hands-on experience across 100+ crop cycles. See the Agronomy Wiki.
| Factor | Ideal range for carnation |
|---|---|
| Season | Best in cool and mild regions; cooling needed in hot months |
| Growing temperature | 15–25 °C by day, 10–12 °C at night |
| Relative humidity | 60–70% |
| Feed TDS | About 1,000–1,200 ppm |
| Feed pH | 5.5–6.5 |
| Plant density | About 25–30 plants per m² |
| Support | 3–4 layers of support net |
| Growing system | Cocopeat troughs or raised beds with drip |
Crop cycle
From seedling to last harvest
One carnation crop lasts about 12–14 months from planting to the last picking.
- 01
Day 0
Planting
Rooted cuttings are planted shallow so the stem base stays dry.
- 02
Weeks 3–4
Pinching
The growing tip is pinched so each plant gives 3–4 flowering shoots.
- 03
Weeks 4–12
Netting
Support nets are raised as plants grow to keep stems straight.
- 04
Months 3–4
Disbudding
Side buds are removed on standard types so one large flower forms.
- 05
4–5 months
First flowers
The first stems are cut at paint-brush stage.
- 06
8–10 months
Picking
Stems are cut every few days through the season.
Plant protection
Common carnation 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 |
|---|---|---|
| Fusarium wilt | Plants yellow and wilt on one side | Clean cuttings, clean cocopeat, remove infected plants |
| Stem rot | Rot at the stem base | Plant shallow, keep the stem base dry |
| Thrips | Streaked petals | Blue sticky traps, double-door entry |
| Spider mites | Speckled, dry leaves | Check leaf undersides weekly |
| Aphids | Sticky, curled shoots | Insect net, yellow sticky traps |
| Calyx splitting | Split flower base | Steady night temperature, even feeding |
Harvest and selling
Pick, grade and sell
Careful picking and grading decide the price you get.
- Cut at paint-brush stageCut standard types when the petals show colour like a paint brush; spray types when two flowers are open.
- Into water at onceStand stems in clean water and move them to a cool room.
- Grade and bunchGrade by stem length and bunch in 20s.
- Sell with live pricesTrack rates on Price Watcher and reach buyers through Buyers Connect.
