1、 Soil

Potting requires loose, fertile and humus containing sandy soil. Perlite or coarse sand, honeycomb briquette slag and humus can also be used as basin soil to ensure the water permeability of the soil

2、 Temperature

It is cold resistant but not heat-resistant. When overwintering, the underground bulbs can withstand the low temperature of more than 10 degrees below zero and can spend the winter outdoors. However, if the temperature is higher than 30 degrees in summer, it will stop growing. It is recommended to breed in an indoor temperature environment

3、 Watering

It requires a certain amount of moisture and a humid environment. Watering should be done immediately. Don't water too much. If there is water in the basin soil, it will cause root rot. When watering in the seedling stage, we must pay attention to the choice of spraying watering method, and we can't just water

4、 Illumination

It is a sun loving plant. It needs sufficient sunlight during maintenance. When the light is insufficient, it will grow slowly. When planting indoors, we should pay attention to give it sufficient light, and it is best to breed in balcony and other places

5、 Precautions

1. Fertilization: common organic fertilizer can be selected as fertilizer. Fertilizer should be applied frequently. The amount of fertilizer applied in a single time should be small and the effect is the best

2. Diseases and pests: the soil can be sterilized before planting, and Bordeaux liquid, chlorothalonil and methyl tobuzin can be sprayed regularly during the growth period to prevent and control diseases and pests
