Causes of Yellowing Leaves on Lotus Bamboo and How to Fix Them

Whether grown in soil or in water, lotus bamboo (Dracaena sanderiana) can develop yellowing leaves at the base or on the tips of its stems. Lotus bamboo is highly valued for its ornamental appeal mainly because of its glossy green leaves, and its tall, jointed, tiered form is very appealing. Yellowing leaves spoil its looks. What causes lotus bamboo leaves to turn yellow?

Causes of Yellowing Leaves on Lotus Bamboo

Sunburn caused by intense sunlight

Lotus bamboo prefers shaded conditions. Grown indoors with little light, it can still grow very well as long as water and nutrients are sufficient. Some growers worry that it lacks light, so they place it on a balcony or windowsill, unaware that strong light can damage lotus bamboo leaves. Direct intense sunlight hitting lotus bamboo easily causes the leaf tips and leaf margins to dry out and wither, and yellow patches appear on the parts of the leaves facing the sun.

Yellowing leaves caused by lack of light

Although lotus bamboo likes shaded, cool environments, leaving it in such conditions for a long time is also not good, since the plant cannot carry out photosynthesis at all. Placed in a shaded environment for a long time, the leaves cannot get enough sunlight and cannot form chlorophyll, so the whole plant's leaves turn yellow and then drop off.

Fertilizer too concentrated or too much fertilizer

Yellowing of lotus bamboo caused by too much fertilizer or overly high concentration shows as dry brown tips on new leaves; the leaf surface is generally thick and lacks gloss, and is uneven and not smooth, while old leaves turn scorched yellow and drop off.

Yellowing leaves caused by fertilizer deficiency

Growers using soil or water culture have all had this experience: after not fertilizing the plant for a long time, they notice signs of yellowing on the leaves at the stem tips. This is yellowing caused by fertilizer deficiency. It shows as young leaves becoming paler in color, turning yellow or pale green, while older leaves remain relatively normal or gradually turn from green to yellow.

What to Do When Lotus Bamboo Leaves Turn Yellow

Managing light conditions

Lotus bamboo does like cool, shaded environments, but it cannot go without sun all the time either; occasionally move it out for photosynthesis so the plant's leaves become greener and more beautiful.

When moving it out to get sun, avoid sun exposure when the light is intense. Otherwise, strong light will scorch the leaves, and yellow patches are not a good look.

Managing water and fertilizer

If the fertilizer concentration is too high or too much fertilizer was applied, stop fertilizing immediately; in severe cases, use a large amount of water to flush out some of the fertilizer.

For yellowing leaves caused by fertilizer deficiency, apply light fertilizer frequently and add some alum water at the appropriate time. In addition, lotus bamboo is a foliage plant, so it should be given fertilizer mainly based on nitrogen, which can make the leaves a fresh, dark green.
