What to Do When the Leaves of the Lucky Bamboo Plant Turn Yellow? Here Comes the Latest Solution
Lucky bamboo is one of the most common ornamental plants, and many people like to grow it. Yellowing leaves are a fairly common occurrence in lucky bamboo cultivation. Although lucky bamboo is relatively easy to grow, and yellowing leaves may not seem like a big problem, they still affect the ornamental value of the lucky bamboo and the beautifying effect on the home. What should you do when the leaves of the lucky bamboo turn yellow? Let's take a look together below!
Yellowing leaves caused by normal aging
[Cause of yellowing] If cared for properly, yellowing leaves on lucky bamboo are normal metabolism. As the plant grows, the lower leaves begin to age and turn yellow.
[Solution] There is no need to worry about yellowing leaves caused by normal aging in lucky bamboo, but the yellow leaves, residual leaves and some old leaves at the lower part of the plant should be trimmed in time.
Yellowing leaves caused by overwatering
[Cause of yellowing] Lucky bamboo has a fleshy root system and is most afraid of waterlogging. Therefore, it should not be watered too much, otherwise it easily causes root rot, which in turn leads to yellowing leaves on the lucky bamboo.
[Solution] Usually just water an appropriate amount. Water only when the potting soil is dry; it is better to keep it on the dry side than too wet. Except in summer, when the potting soil should be kept moist, watering in spring and autumn should not be too frequent. However, the air must be kept humid, because if the air is dry, undesirable phenomena such as yellowing leaves on lucky bamboo are also likely to occur.
Yellowing leaves caused by excessive sunlight
[Cause of yellowing] Lucky bamboo likes a semi-shaded environment and avoids direct strong light in summer. Direct strong light easily causes the edges of lucky bamboo leaves to scorch or even turn yellow and withered. Too strong light easily causes sunburn, while too weak light makes it difficult to bloom and bear fruit, affecting the ornamental effect.
[Solution] In spring, summer and autumn, lucky bamboo should be shaded by more than 60%, and in winter by 40%.
Yellowing leaves caused by too low a temperature
[Cause of yellowing] The suitable growing temperature is 15-18℃, and the lowest temperature must not be lower than 5℃, otherwise frost damage easily occurs, causing the leaves to turn yellow.
[Solution] In winter, dormant lucky bamboo should be moved into a greenhouse and placed in a sunny spot, with the temperature kept above 10℃. The following year it can sprout new leaves again.
Yellowing leaves caused by excessive fertilizing
[Cause of yellowing] Excessive fertilizing is another common cause of yellowing leaves on lucky bamboo. It mainly causes fertilizer burn, damaging the root system of the lucky bamboo and so on.
[Solution] During the growing season, apply liquid fertilizer once every 10-15 days, and stop fertilizing in winter.
Yellowing leaves caused by insect pests and diseases
[Cause of yellowing] Brown soft scale insect pests can also cause yellowing leaves on lucky bamboo. When brown soft scale harms lucky bamboo leaves, it generally gathers on the leaf surface or tender leaves, pierces and sucks the plant's sap, and at the same time excretes sticky liquid. Its excrement easily causes a large proliferation of sooty mold pathogens, making the stems and leaves turn black, affecting the plant's photosynthesis, resulting in weak growth, yellowing leaves, and impaired ornamental value.
[Solution] If there are few affected plants, or the number of insects is small, generally scraping off the insects with a bamboo strip or similar object is enough. If during the insect hatching period, spray with 40% dimethoate emulsifiable concentrate at 1000 times dilution (or 40% omethoate emulsifiable concentrate at 1000 times dilution), and spraying with 5% phosmet emulsifiable concentrate at 1000 times dilution can also kill them.
Yellowing leaves caused by leaves being too dirty
[Cause of yellowing] Usually, care should be taken to keep the leaves of lucky bamboo clean and tidy. If too much dust accumulates on the leaves and affects photosynthesis, it will also cause the leaves of lucky bamboo to turn yellow.
[Solution] At regular intervals, wipe the leaves with a clean damp cloth and so on to keep the leaves clean.
