How to Propagate Calla Lilies? Detailed Introduction to Propagation Methods
The main propagation method for calla lilies is division by tubers. After the plant enters dormancy, peel off the small bulbs around the tuber and plant them separately. They can also be propagated by seed; once the seeds mature, sow them in pots, with an optimal germination temperature of around 20°C. Now let's take a look at the propagation methods for calla lilies!
Seed Propagation of Calla Lilies
Seed propagation of calla lilies is mainly done by sowing in pots indoors, with an optimal germination temperature of 18-24°C. Germination occurs 15-20 days after sowing, and seedlings need 3-4 years of cultivation before they can bloom.
Division Propagation of Calla Lilies
1. Tuber division method: At the end of May, when calla lilies begin to enter dormancy, reduce watering to prompt them into faster dormancy. After all the leaves turn yellow, take out the tubers and store them in a ventilated, shady place. When autumn arrives, plant them in grades according to tuber size.
2. Plant division method: Calla lilies generally enter dormancy after blooming in spring due to rising temperatures. The plant division method involves not letting them go dormant, but instead placing them in a well-ventilated spot to continue growing. When autumn arrives, divide them while repotting, splitting the calla lily into 2-3 pots according to plant size.
Common Cultivated Varieties of Calla Lilies
Common cultivated varieties of calla lilies include red calla lily, yellow calla lily and silver star calla lily, distinguished by the color of the spathe.
1. Red calla lily: The red calla lily is relatively short, with narrow arrow-shaped leaves and a peach-red spathe.
2. Yellow calla lily: The yellow calla lily has arrow-shaped, bright green leaves with translucent white spots, a longer stalk, and a yellow spathe.
3. Silver star calla lily: The silver star calla lily has silver-white spots on its leaves, a short stalk, and a creamy white spathe.
