Reason: Narcissus leaves grow without flowering is likely to be the poor quality of the seed ball, germination ability is weak, less stored nutrients, even if the flower arrow will not blossom.
Solution: When planting, choose a plump, firm and elastic bulb, or choose a bulge on the side of the bulb, so that there will be more flower arrows germinating in the later period, which can promote faster flowering.
Reason: Daffodils are suitable for growing in a warm environment. If the temperature is too high or too low during the bud formation period, the flowers will be inhibited from blooming, and the situation of only growing leaves but not blooming will occur.
Solution: During the bud period, pay attention to the temperature control, the temperature can be controlled between 10 degrees and 15 degrees in the daytime, and the temperature at night can be maintained between 8 degrees and 10 degrees, so that the temperature environment can promote the daffodils to blossom better.
Reason: Daffodils are basically water-raised, but if they are in a wet environment all day, the water content will be too high, and there will be a phenomenon of only growing leaves but not buds.
Solution: During the period of water culture, the water should be poured out at night, a quarter of the original water should be poured out, and the water should be replenished the next day, so as to improve the probability of flowering and solve the phenomenon of non-flowering.
