1、 Breeding method

1. Sunshine: Purple Calla needs to grow in a sunny environment. The light should be kept for 3-5 hours every day, and the flowering period can be appropriately extended. However, direct sunlight should be avoided, especially in summer. Proper shading is needed to avoid burning leaves

2. Temperature: Purple Calla is suitable to grow in an environment between 15 ℃ and 25 ℃. Too high temperature will lead to its dormancy. It needs proper cooling. You can spray some water on the leaf surface

3. Soil: the soil for planting purple Calla needs good water retention. The soil with acidity and viscosity should be generally neutral. Ferrous sulfate can be used to improve the pH of soil in the north

4. Watering: Purple Calla likes to be wet. Because the cohesive soil has good water retention, it can be watered if the soil is a little dry. Pay attention to avoid ponding

5. Fertilization: Purple Calla has a great demand for fertilizer. Topdressing should be carried out every two weeks, and rotten bean cake water and compound fertilizer should be applied in turn. The amount of fertilizer can be increased after budding, which can prolong the flowering period and make the flowers large and colorful

2、 Reproductive skills

The propagation of purple Calla is dominated by ball division. During plant dormancy, take out the small balls around the tubers and plant them. In addition to ball splitting, it can also be propagated by sowing. The temperature is controlled at about 20 ℃, and it can germinate after half a month of pot sowing

3、 Pest control

Purple Calla is prone to rot during dormancy. It can be diluted and sprayed on the surface with acetic acid solution. In addition, it will also be infringed by red spider and thrips. It can be sprayed with ethyl acaricide diluent
