What causes narcissus flowers to have no fragrance

1. Buying inferior flower bulbs

There are now many lower-quality narcissus bulbs on the market. In some bulbs, the circumference of the main bulb in the middle does not reach 15 cm, which shows that they have not fully developed. When you buy bulbs like these, no matter how well you care for them, no matter how suitable the environment is, and no matter how sufficient the nutrients are, they will only grow leaves. Excessive leaf growth will consume most of the nutrients, which will lead to fewer and fewer flowers, and even the flowers that do open will not have much fragrance, or even no fragrance at all.

2. The care temperature is too high

This plant originates in the wild, and its flowering period is in the early spring, when the outdoor temperature is relatively cool. When we grow it indoors, especially in winter, the indoor temperature can reach around 20°C, which easily causes its leaves to grow excessively and likewise consumes most of the nutrients, which affects both the number of flowers and the fragrance. The daytime temperature is best maintained between 10°C and 12°C, and the nighttime temperature is best maintained between 5°C and 7°C. This not only helps the flowers open, but also increases the fragrance of the flowers.

The above are the two main reasons why your narcissus blooms but has no fragrance. Finally, a reminder to friends: under normal temperature conditions, ensuring 1 hour of light every day will make the fragrance of the flowers even richer.
