The color Calla can be planted in spring or autumn, and the general varieties can be planted in late August, avoiding high temperature summer and cold winter as much as possible. However, if the temperature is suitable, it can also be planted. If it is in a greenhouse, it can be planted all year round if the temperature is above 18 ℃. Planting must be carried out at a suitable time to help it take root.
The color Calla is suitable for growing in the culture soil with good ventilation and drainage. The soil used for planting should be slightly acidic soil with humus. When mixing soil, garden soil, peat soil, rotten leaf soil and plant ash can be mixed in the proportion of 3:3:2:1. If you have rotten sawdust at home, you can also add some and mix it evenly.
The soil to be used should be disinfected in advance, because there may be bacteria or eggs in the soil. If it is not disinfected, the seed ball of the most plant will be harmful after planting. It can be disinfected with medicine, or it can be put in the strong sunlight, and it can also be disinfected well after a few days exposure.
