Propagation: Liliums are commercially propagated through bulbs. A six week cold storage period at 2oC to 5oC is needed to break dormancy. Bulbs can be stored at - 20C up to one year.

Spacing: 20 x 15 cm, 15 x 15 cm or 15 x 10 cm (plant density varies between 30 and 60/m2 depending on cultivar and bulb size) 

Irrigation: 6- 8 litres/m2/day during summer and 5 - 6 litres/m2/day during winter
