Why do daffodils only grow tall and do not bloom?

1, poor bulb quality. High-quality bulbs are full, flat and round, with thick scales and milky white. They are planted on bulbs and layered into balls. If the bulbs selected are small or diseased, the packaging is dry or there are a few residual roots connected, which will lead to insufficient nutrition of leaf buds in the later development and lead to no flowering;

2. Improper cutting. In the carving of narcissus, because of too much cutting coating or the wound destroying the bud, it is stunted and does not bloom;

3. Improper hydroponics methods. Narcissus likes clean water. If the water quality is not clean and turbid, it is easy to cause root rot if the water is not changed frequently. Narcissus is a light-loving plant. If the light is insufficient, the poorly ventilated leaves will be slender and weak, which will affect the development of flower buds.

4. The hydroponics season is wrong. Bulb dormancy and temperature rise above 15 degrees should be avoided, otherwise it will cause no flowering. For example, when the bulb is dormant before the first frost or the temperature rises after Qingming, hydroponics is difficult to bloom.
