75% shade net house with 70 – 80% relative humidity, day temperature of 24 – 280C and night temperature of 15 – 220C.
Porous organic media such as leaf mould and cocopeat is ideal. A mixture of 1 part each of coir pith, leaf mould, cattle manure, coarse sand, brick pieces, charcoal, neem cake and coconut husk pieces is highly suitable.

Propagated through tissue culture or suckers. Tissue culture plants are widely used for commercial cultivation.

Grown in pots or raised beds. Tissue culture plants of 15 cm height with 4-6 leaves are ideal for planting.

Mist or overhead sprinkler to provide water and to improve relative humidity

Pot cultivation
Foliar application of 0.2% of NPK @ 30:10:10 during vegetative stage and 10:20:20 during flowering stage is adopted for pot cultivation. Fertigation can be adopted for raised bed cultivation.

Raised bed cultivation
For the first 6 months spray plants with a solution of cow dung and DAP @ 250 ml/plant (10 kg of cow dung + 2 kg of DAP dissolved in 200 l of water and the decanted solution is used for spaying). After 6 months fertigation is adopted with the following schedule.
Fertilizer                                                                                                                    Quantity (g/100m2)
Schedule ‘A’ – Weekly once
Calcium Nitrate                                                                                                                              250
Potassium Nitrate                                                                                                                          150
Micro nutrients                                                                                                                               50
Schedule ‘B’ – Weekly once
Mono Ammonium Phosphate                                                                                                      250
Potassium Nitrate                                                                                                                           100
Magnesium Sulphate                                                                                                                      50

Leaf pruning
Leaf pruning retaining 4-6 leaves per plant has to be taken up at regular intervals to avoid disease problem and to promote flowering.

Aphids : Spray dimethoate @ 3 l/l
Scale insects : Spray malathion @ 1 ml/l
Spider mites : Spray wettable sulphur @ 3 g/l or propargite @ 2 ml/l
Thrips : Spray fipronil @ 1.5 ml/l

Anthracnose: Spray carbendazim @ 1g/l
Leaf spot : Spray carbendazim @ 1 g/l or mancozeb @ 2g/l
Root rot : Soil drenching with captan @ 2g/l
Bacterial wilt: Spray streptomycin sulphate @ 0.1g/l

Plants start flowering from 6-8 months after planting. Harvesting is done at 1/3 colour change on the spadix (i.e. opening of 1/3 of true flowers on spadix) or the angle between the spathe and spadix should be 45 oC.

7- 9 flowers/plant/year.
