1、 Poor seed ball quality

Reason: daffodils grow long and their leaves do not bloom. It is likely that the quality of seed balls is too poor, the germination ability is weak, and the stored nutrients are less. Even if they grow flowers and arrows, they will not bloom

Solution: when planting, the seed ball should be full, solid and elastic, or the one with bulge on the side of the bulb, so that there will be more flowers and arrows germinating in the later stage, which can promote faster flowering

2、 Temperature discomfort

Reason: Narcissus is suitable for growing in a warm environment. If the temperature is too high or too low during bud pregnancy, it will inhibit its flowering, and there will be only leaves without flowering

Solution: pay attention to control the temperature during pregnancy. The temperature during the day can be controlled between 10 degrees and 15 degrees, and the temperature at night can be maintained between 8 degrees and 10 degrees. Such a temperature environment can promote the better flowering of daffodils

3、 Too much water

Reason: daffodils are basically hydroponic, but if they are in a wet environment all day, the water content will be too high, and there will be only leaves without flower buds

Solution: during the water cultivation period, the water shall be distributed at night, one quarter of the original water shall be poured out, and the water shall be supplemented the next day, so as to improve the probability of flowering and solve the phenomenon of non flowering
