Production of quality flowers requires shade house (50%) or naturally ventilated polyhouse. Day temperature of 22-25ºC and night temperature of 12-16ºC are ideal.

Well drained, rich, light, neutral or slightly alkaline soil with pH range of 5.5 – 7.0.

Commercially propagated through division of suckers and tissue culture plants.

Soil fumigation with Formaldehyde (100 ml in 5 l/meter sq.) or Dazomet (30 g/meter sq.) is recommended to control soil borne pathogens (Phytophthora, Fusarium and Pythium).
Raised beds of 1-2 m width and 30 cm height are prepared. Growing media consisting of FYM: sand: cocopeat/paddy husk (2:1:1) is ideal.

40 x 30 cm or 30 x 30 cm

Drip irrigation with 500-700 ml of water/day/plant
