An Analysis of 11 Causes of Yellowing Leaves in Lucky Bamboo

Through the natural metabolism of lucky bamboo, old leaves will turn yellow, dry up and fall off. As the lucky bamboo plant grows, the leaves at the bottom begin to age and turn yellow.

Lucky bamboo has fleshy roots and is most afraid of waterlogging. Therefore, it should not be watered too much, otherwise root rot is easily caused, which in turn leads to yellowing leaves.

Forgetting to water lucky bamboo leads to overly dry potting soil, the roots and stems lack moisture, causing leaves to turn yellow.

Lucky bamboo prefers a semi-shaded environment and avoids direct strong light in summer. Direct strong light easily causes the leaf edges of lucky bamboo to scorch or even turn yellow and withered, and too much light easily causes sunburn.

When lucky bamboo lacks light for a long period, the chlorophyll in the leaves decreases, causing the green color of the leaves to gradually disappear, showing signs of chlorosis, and the leaves turn yellow and white.

Keeping lucky bamboo in a poorly ventilated environment for a long time, especially in the hot summer with poor ventilation and improper shading, commonly causes yellowing leaves. In addition, when lucky bamboo leaves grow too densely and are not pruned for a long time, the inner branches and leaves cannot receive light, which easily causes the inner leaves to turn yellow.

The suitable growing temperature is 15—18°C, and the minimum temperature should not be lower than 5°C, otherwise cold damage easily occurs and causes leaves to turn yellow.

Overfertilizing is another common cause of yellowing lucky bamboo leaves. It mainly causes fertilizer burn, damaging the root system of lucky bamboo and so on.

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 lucky bamboo leaves to turn yellow.

Brown soft scale pest infestation can also cause lucky bamboo leaves to turn yellow. When brown soft scale harms lucky bamboo leaves, it usually gathers on the leaf surface or young leaves, pierces and sucks the plant's sap, and at the same time excretes sticky liquid. Its excrement easily causes sooty mold fungi to multiply in large numbers, making the stems and leaves turn black, affecting the plant's photosynthesis, causing weak growth and yellow leaves, and harming its ornamental value.

When planted in the ground or in pots, lucky bamboo dislikes hard clay and alkaline soil. Generally, lucky bamboo grown in the north is prone to yellowing leaves caused by soil and water tending toward alkalinity.

Causes of yellowing leaves in lucky bamboo

When growing lucky bamboo at home, you may encounter yellowing leaves. At this time, do not panic. First determine the cause, then treat the problem accordingly to solve the yellowing leaves of lucky bamboo!

Yellow leaves caused by long-term fertilizer deficiency

If lucky bamboo has not been given nitrogen fertilizer for a long time or the pot or water has not been changed, and the water lacks nitrogen and other nutrient elements, the branches and leaves become thin and weak, and the leaves are thin and yellow. If the lucky bamboo is hydroponic, it should be promptly moved into fresh culture water and gradually given dilute decomposed liquid fertilizer or compound flower fertilizer.

Yellow leaves caused by overfertilizing

If too much fertilizer is applied, the new leaves of lucky bamboo will become thick and fleshy, with many uneven bumps, and the old leaves will have dry tips, scorched yellow edges and fall off. Fertilizing should be stopped immediately, and the amount of water changed should be increased so the fertilizer is leached away, or the plant should immediately be repotted, the bulbs rinsed with water, and then replanted in the pot.

Yellow leaves caused by hot high temperatures

If flowers are placed in a high-temperature location and exposed to direct strong sunlight, it very easily causes the tips and edges of young leaves to scorch, or leaves to turn yellow and fall off. They should promptly be moved to a well-ventilated, cool place.

Yellow leaves caused by excessive shading

If flowers are kept in a shaded place or a place with insufficient light for a long time, the branches and leaves will turn yellow.

Yellow leaves caused by soil and water tending toward alkalinity

Because the water lacks absorbable soluble iron and other elements, lucky bamboo leaves will gradually turn yellow. When planting, acidic soil and water should be chosen, and during the growing period, alum fertilizer water should often be applied.

Yellow leaves caused by dense, unventilated growth

If too much nitrogen fertilizer is applied, the branches and leaves of lucky bamboo grow too lushly, and combined with long-term lack of pruning, the inner branches and leaves receive insufficient light, which easily causes leaves to turn yellow and fall off. Fertilization should be reasonable and pruning strengthened so as to provide ventilation and light.

Yellow leaves caused by dry air

When indoor air is excessively dry, flowers often show dry leaf tips or scorched leaf edges. Attention should be paid to methods such as misting and covering with plastic film to increase air humidity and prevent yellowing leaves from occurring.

Yellow leaves caused by improper temperature

If the indoor temperature in winter is too low, the flowers suffer cold damage, which causes leaves to turn yellow, and in severe cases they wither and die. If the indoor temperature is too high, the plant's transpiration is excessive, and the roots cannot supply enough water and nutrients, which also causes leaves to turn yellow. Please pay attention to adjusting the indoor temperature in time.

Yellow leaves caused by pests and diseases

Leaf spot disease caused by infection by fungi and other pathogens easily causes local necrosis of leaves, with yellow spots or patches appearing, and in severe cases the entire leaf withers, turns yellow and falls off. After infection by mosaic virus, yellow-green mottled patches appear on the leaves; damage by scale insects, red spiders and the like also occurs.

Yellow leaves caused by strong irritation

When preventing and controlling pests and diseases, using pesticide at too high a concentration, or contamination by toxic gases in the air, or suddenly watering with cold water when the temperature is high, can all easily cause the leaf tips or parts of the leaf surface to turn yellow and scorch, or even cause the whole plant to wither and die. Therefore, attention should be paid to the reasonable use of pesticides, and efforts should be made to eliminate sources of air pollution. In midsummer, avoid watering flowers with cold water around noon.

Yellowing of lucky bamboo leaves is sometimes caused by one reason, but most of the time it is caused by multiple factors. Therefore, a correct diagnosis should be made before treating the problem accordingly.
