Breeding is mainly based on sub-ball breeding. After the plant enters dormancy, peel off the small balls around the tuber and plant it separately. You can also sow and propagate, and sow in pots when the seeds are mature. The optimum temperature for germination is about 20℃. [4]

Calla lily usually plants balls after autumn. The row spacing between beds is 25㎝, and the plant spacing 10㎝ is fertile and slightly sticky soil, such as: 2 portions of garden soil, rice bran ash 1 portion, and a little bit of bone meal or manure; It can also be prepared with 2 parts of fine pond mud, humus soil (or compost) 1 part, and appropriate amount of calcium superphosphate and decomposed cow dung. After planting, cover the soil with a thickness of 3 ~ 4 ㎝, and seedlings can emerge in about 20 days. Calla lily likes to have enough water during its growth, so it is necessary to sprinkle water on the leaves and the ground frequently, and pay attention to the cleaning of the leaves. Topdressing liquid fertilizer 1 time every half month. Rinse with clear water immediately after fertilization to prevent accidents. Before frost, move into a greenhouse and keep the room temperature above 10℃.

It is difficult to sow and reproduce calla lily. It is suggested that you breed in groups.
