Four Key Points to Prevent Narcissus "Silent Flower"
A comprehensive explanation of the related topics about bulbous flowers narcissus, focusing on the four key points to prevent narcissus "silent flower". The following is a detailed introduction.
"Silent flower" in narcissus refers to the phenomenon where the flower bud withers and turns yellow before it blooms. The occurrence of "silent flower" is related to factors such as poor bulb quality, improper carving, and incorrect hydroponic methods. To prevent "silent flower" in narcissus, the following aspects should be paid attention to during maintenance.
1. Selecting Quality Bulbs
When selecting bulbs, one should first observe their shape. The main bulb should be oblate, with broad shoulders on both sides of the central top bud, and the lateral bulbs should be upright, plump, and large. Secondly, look at the color; the bulb's outer layer should be rough and dark black, indicating a 3-year-old narcissus bulb. Lastly, look at the buds; those with many full buds are good. If the selected bulb is small, diseased, or with dried roots, it will lead to insufficient nutrients for the flower bud in later development.
2. Careful Carving
In the carving of narcissus, too much cutting of the wrapper or damage to the flower bud from the wound can cause poor development of the flower bud. When carving, first remove the outer yellowish-brown skin and the dry, rotten roots, and be as careful as possible to avoid injuring the flower bud.
3. Clean Water Quality
Narcissus prefers clean water. If the water is not changed frequently and becomes turbid, it can easily cause root rot. It is best to use rainwater or pond water; if tap water is used, it should be allowed to sit for 1 to 2 days before use. After hydroponic culture, change the water every other day, and be especially careful to change the water when the temperature is high.
4. Moderate Light and Temperature
Narcissus is a photophilous plant and should be placed in a well-ventilated and sunny area to maintain adequate sunlight. If there is insufficient light or poor ventilation, the leaves will become thin and weak, affecting the development of the flower bud. The optimal growth temperature for narcissus is between 10°C and 20°C; if the temperature drops below 5°C, it is prone to frost damage. Therefore, hydroponic culture before the bulb's dormant period at the time of frost descending or after the temperature rises at Qingming is difficult to bloom.
The above is the specific content of the four key points to prevent narcissus "silent flower" for everyone's reference and operation.
