What is the reason for the sudden yellowing of the富贵竹 (Fortune Bamboo)?
The editor will share with you the reasons for the sudden yellowing of the Fortune Bamboo and some small experiences in green plant maintenance about remedial measures for yellow leaves, as follows:
Fortune Bamboo was introduced to our country in the 1980s. Although there is "bamboo" in its name, it is quite different from real bamboo. It belongs to the Agavaceae, Dracaena genus, and is a perennial evergreen small tree. Due to its delicate stems and leaves, it looks quite like bamboo, and with its relatively small size, it is suitable for keeping at home, making it very popular among people.
As an ornamental foliage plant, once the Fortune Bamboo has yellow leaves, it not only affects its appearance but also is not conducive to its growth, so immediate treatment is required. However, there are many reasons for yellow leaves, and it is necessary to apply the right remedies.
I. Winter yellowing
The main reason for the yellowing of Fortune Bamboo in winter is that the plant gets frostbitten. It originally grows in tropical and subtropical regions and is not cold-resistant. When the temperature drops below 10°C in winter, the growth of the plant will be affected. If the temperature drops further, the root's water absorption capacity will weaken, leading to yellowing of the leaves.
Tip: Yellowing caused by frostbite often shows yellow-brown spots on the leaf tips and edges.
Solution: For low-temperature frostbite, first move the plant to a warm indoor area to prevent further deterioration. Then, wipe its surface with cotton and cut off the yellowing and withered leaves. Wrap it with newspaper or cloth, leaving a ventilation opening. This will allow the plant to gradually recover.
II. Summer yellowing
Fortune Bamboo is not afraid of high temperatures, but it prefers a semi-shaded environment and should not be exposed to direct sunlight. If it is not shaded in summer and exposed to direct sunlight for a long time, the leaves will also turn yellow. Moreover, it can lead to water loss in the leaves and slow down growth.
Tip: Yellowing caused by exposure often concentrates on the sunny side and is more common at the top.
Solution: After the plant is sunburned, immediately move it to a shaded area to avoid further sunlight exposure. Cut off the yellowed part, but there is no need to cut off the entire leaf. Also, ensure good ventilation, and once it recovers, move it to a semi-shaded area with scattered light.
III. Hydroponic yellowing
After the Fortune Bamboo has rooted in hydroponics, there is no need to change the water. If the water evaporates and decreases, just add water. Frequent water changes often cause the roots to readjust to the environment, which can affect the plant's water absorption and lead to dry leaves.
Solution: Stop changing the water for the Fortune Bamboo, place it in a semi-shaded area, maintain good ventilation, and check the water level in the container daily. If the water is low, add water promptly.
IV. Yellowing due to nutrient deficiency
Any plant's growth cannot do without the help of fertilizers, and Fortune Bamboo is no exception. If it is not fertilized for a long time, the plant will grow weak and the leaves will turn yellow.
Tip: Yellowing of leaves due to nutrient deficiency is often seen in new leaves.
Solution: Fortune Bamboo can grow throughout the year, so there is no restriction on fertilization time. As soon as you notice a nutrient deficiency, you can immediately supplement the fertilizer. The main choice is compound fertilizer, which can comprehensively supplement nutrients. For hydroponics, you can also add nutrient solution, which works well.
The above sharing on the reasons for the sudden yellowing of Fortune Bamboo and the specific introduction of remedial measures for yellow leaves, I hope you will like it!
