How to grow Clivia, how to fertilize, when to change soil

The soil should not be too dry or too wet. Every time it is watered, it must be thoroughly watered, and some more should be watered after budding. Every 20 days or so, combine watering with fermented bean cake water, fresh fish water and horseshoe water to combine watering and fertilization. The magnolia should be applied once in winter with solid fertilizer, less nitrogen fertilizer, more phosphate fertilizer and potash fertilizer.
