Causes of Yellowing Leaves in Narcissus and How to Treat Them
During the Lunar New Year festival, many people love to grow flowers with a unique fragrance, and narcissus (Narcissus tazetta) is a great choice. Its scent is hailed as the folk "Luoshen Fragrant Concubine," and it also carries very good meanings, symbolizing good fortune and prosperity. However, during care, many flower lovers encounter the problem of yellowing leaves. What is going on? Is there any way to solve it? Let's find out together in the following article.
Narcissus is actually relatively easy to care for, but during its growth period it has a considerable demand for nutrients. If only daily watering is given at this time, it cannot meet its nutrient supply, and this will cause the narcissus leaves to turn yellow. The first-aid method when this happens is to give it fertilizer containing nitrogen, and after a period of care it can recover. In addition, another situation where narcissus leaves turn yellow is caused by a lack of iron itself. It is recommended to regularly supplement it with fertilizers such as ferrous sulfate in daily care, which can effectively prevent and treat yellowing leaves in narcissus.
Another cause of yellowing leaves may also be the surrounding temperature. Generally speaking, yellow leaves occur most often in summer and winter, because people like to place narcissus near windowsills or sunny spots on balconies. In summer, when the temperature is high and the sun is strong, a slight mistake can cause its leaves to turn yellow. Conversely, in winter, because the temperature drops, if cold protection is not paid attention to at this time, yellowing leaves caused by cold damage are also likely. The first-aid method when this happens is to add shading boards and other tools in summer, and in winter change the placement position and put it in a space with a room temperature of around 20 degrees.
The last thing most people overlook is pruning. For narcissus, if it is not pruned for a long time, its internal air permeability will worsen, making it easy for bacteria to breed and pests and diseases to occur. In short, too many leaves are unfavorable to the growth of all plants. It is recommended at this time to prune the overly dense leaves. First, this allows nutrients to be concentrated; second, it can also achieve the purpose of ventilation and light transmission, and at the same time it can also prevent leaves from turning yellow.
