What are the latest propagation methods for calla lilies?
The propagation of calla lilies is mainly done by dividing the tubers. After the plant enters dormancy, peel off the small tubers around the tuber and plant them separately. They can also be grown from seed. Once the seeds are mature, sow them in pots. The suitable germination temperature is 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. The suitable germination temperature is 18-24°C, and germination occurs 15-20 days after sowing. Seedlings need 3-4 years of cultivation before they can flower.
Division propagation of calla lilies
1. Tuber division method: At the end of May, when calla lilies begin to enter dormancy, reduce watering to encourage them to enter dormancy faster. Wait until all the leaves turn yellow, then take out the tubers and store them in a ventilated, cool place. When autumn arrives, grade and plant them according to tuber size.
2. Plant division method: Calla lilies generally enter dormancy after flowering in spring due to rising temperatures. The plant division method does not let them go dormant, but instead places them in a well-ventilated spot to continue growing. When autumn arrives, divide them during repotting, splitting the calla lily into 2-3 pots according to plant size.
Cultivated varieties of calla lilies
Common cultivated varieties of calla lilies include red-flowered, yellow-flowered, and silver-star calla lilies, distinguished by the color of the spathe.
1. Red-flowered calla lily: The red-flowered calla lily is a shorter plant with narrow hastate leaves and a peach-red spathe.
2. Yellow-flowered calla lily: The yellow-flowered calla lily has hastate, bright green leaves with translucent white spots, a longer petiole, and a yellow spathe.
3. Silver-star calla lily: The silver-star calla lily has silvery-white spots on its leaves, a short petiole, and a creamy-white spathe.
