1、 Flowering period

Under normal circumstances, a single plant can bloom twice a year. Once in summer and once in winter. The flowering period is about ten days. If the environmental conditions meet its growth habits, the flowering period can be extended to 15 days and can bloom every year

2、 Flowering maintenance

1. Light and temperature: zhudinghong likes warm, humid and cool climate and is not resistant to heat. The flowering period should be guaranteed to be exposed to astigmatism for six hours every day. If the breeding is outdoors, it should be properly shaded when the sun is big at noon. When flowering in winter, put it in a warmer place and adjust the temperature to between 18 and 25 degrees. Avoid putting it in cold places such as doors and windows to prevent frostbite. If there is floor heating at home, put it high to avoid burning the plant

2. Watering: in its flowering period, the watering frequency needs to be adjusted appropriately to ensure that the soil is wet and there is no ponding. When watering, you can touch the soil while watering. If the soil is all wet but there is no caking, it means that the water is well watered

3. Fertilization: before the full flowering period, a small amount of thin fertilizer containing more phosphorus can be applied to promote flowering

3、 Post anthesis management

After the red flower of Zhuding is withered, the pedicel should be cut off to make the nutrients more concentrated. This is conducive to bulb growth. In addition, it should be fertilized every 20 days or so, which can promote the growth of bulbs and promote it to produce new bulbs
