1、 What kind of fertilizer

Bulbus is in different growth periods and needs different fertilizers. When it was a seedling, its root system could not absorb too much fertilizer, and a small amount of farm fertilizer could be applied. During the growth of the plant, the element containing nitrogen content should be applied to it, which is conducive to the growth of the plant root system. In the pre flowering stage of the plant, phosphorus and potassium fertilizer is mainly applied, which can promote its better flowering

2、 Precautions

1. When applying fertilizer to the plant, apply light fertilizer after ripening, and do not apply fertilizer with too high concentration. The root system of the plant is very weak. If the fertilizer is high, it can not absorb, and the heat generated will burn its root system

2. After entering the winter with low temperature, the growth speed of the plant will slow down, so don't apply too much fertilizer to it at this time. In winter, it is usually carried out every 40-50 days to avoid fertilizer damage

3. When applying fertilizer, do not be close to its root system. Apply fertilizer near the root of the plant, and try not to apply fertilizer on the plant
