Seedlings are pricked out when they are 5 to 6 cm high and potted in polythene bags of size 22.5 cm x 17.5 cm filled with soil based potting mixture. Seeds are also dibbled directly in polythene bags of the above size (Seethalakshmi and Muktesh Kumar, 1998; Chacko et al., 2002).

Vegetative propagation 
Pests  No information (Chacko et al., 2002).
