1、 Breeding environment

1. Soil: it is best to choose slightly acidic sandy soil with rich humus, loose and good drainage

2. Watering: keeping the soil dry and wet is the best state. It is not necessary to water during growth. Just keep it wet. When the temperature is high and the weather is dry, water it appropriately for 1-2 times

3. Fertilization: generally use rotten garbage fertilizer and various cake fertilizer. It is very sensitive to fertilizer. It only needs topdressing 2-3 times from stem and leaf to bud

4. Light: it's best to accept about 8 hours of light every day, which can make it grow better and conducive to its normal flowering. Although it likes sunshine, shading measures should be taken when the sunshine is strong

2、 Breeding method

1. Plant the bulb in a cool place and dry it for 10-9 minutes

2. Sowing and reproduction: seeds need a low temperature of 7-9 ℃ and generally germinate in 30-40 days. Most of them are sown in the open field in autumn. After overwintering, seeds will germinate and emerge, form bulbous roots in June, rise and store after dormancy, and bloom in 5-6 years

3、 Common diseases

Generally, there are gray mold, root rot, etc. the root rot will rot at the initial stage, which has little impact on it. If it is serious, it will lead to flower withering. To ensure better drainage of the soil, disinfect the soil, or spray with chemicals
