What to Do When Phoenix Tail Bamboo Leaves Turn Yellow?
The main reason for the yellowing of Phoenix Tail Bamboo leaves is poor management, caused by improper watering and fertilizing. Here are the causes and remedies described as follows:
(1) Overwatering
Long-term excessive moisture in the potting soil can lead to oxygen deficiency in the soil, causing some fibrous roots to rot, which hinders normal respiration and the absorption of water and nutrients, leading to leaf yellowing and falling. Initially, the young leaves turn light yellow, followed by the gradual yellowing of older leaves. Immediate control of watering is needed, pause fertilizing, and regularly loosen the soil to ensure good soil aeration.
(2) Drought Dehydration
Forgetting to water the plant or long-term partial watering (i.e., wet on top, dry below) can affect nutrient absorption and easily cause the leaves to look dull and lackluster, with wilted and drooping leaves. Initially, the lower older leaves age and gradually turn yellow from the bottom up. In this case, a small amount of watering and misting is needed to gradually restore the plant before returning to normal watering.
(3) Long-term Lack of Fertilizer
Long-term absence of nitrogen fertilizer or failure to repot can lead to a lack of nutrients like nitrogen in the soil, causing weak branches and leaves, and thin yellow leaves. It is necessary to repot and replace with new loose and fertile potting soil, gradually applying diluted decomposed liquid fertilizer or compound flower fertilizer.
(4) Over-fertilization
Too much fertilizer can cause new leaves to become thick and uneven, with old leaves drying and yellowing at the tips and falling off. Fertilizing should be stopped immediately, increase watering to allow the fertilizer to flow out from the bottom of the pot, or repot and rinse the soil clump before replanting.
(5) High Temperature and Heat
In summer, if cool-loving flowers (such as cyclamen, fuchsia, and kaffir lilies) are placed in high-temperature areas with direct sunlight, it can easily cause the tips and edges of young leaves to scorch or turn yellow and fall off. They should be moved to a well-ventilated, shaded area.
(6) Excessive Shading
If sun-loving flowers are kept in shaded or poorly lit areas for a long time, it can lead to excessive growth of branches and leaves, thin yellow leaves, and little or no flowering. Attention should be paid to moving the pot to a sunny area.
(7) Soil and Water Too Alkaline
In most areas in the north, the soil and water contain more salt and alkali, which can cause leaves to gradually turn yellow when planting acid-loving flowers like azaleas, camellias, laughingbushes, gardenias, orchids, white magnolias, and osmanthus, due to a lack of soluble iron and other elements that can be absorbed by the plants. Acidic soil should be used when planting, and iron sulfate water should be frequently applied during growth.
(8) Poor Ventilation
If too much nitrogen fertilizer is applied, causing excessive growth of branches and leaves, combined with long-term lack of pruning, it can easily cause leaves to turn yellow and fall due to insufficient light in the inner parts of the plant. Reasonable fertilization and pruning should be done to ensure ventilation and light.
(9) Dry Air
When indoor air is too dry, some moisture-loving flowers like spider plants and orchids often show symptoms of dry leaf tips or leaf edge scorching. Attention should be paid to increasing air humidity by misting and using plastic film covers.
(10) Improper Temperature
In winter, if the room temperature is too low, warm-loving flowers are easily damaged by cold, leading to yellowing leaves, and severe cases can cause yellowing and death. If the room temperature is too high, excessive transpiration can lead to insufficient supply of water and nutrients from the roots, causing leaf yellowing. Adjust the room temperature in a timely manner.
(11) Soil Too Acidic
Southern red soil is too acidic, causing elements like magnesium to easily leach out, which can lead to interveinal chlorosis and yellowing of older leaves in alkaline-tolerant or slightly alkaline soil-loving plants like oleanders, boxwoods, and forsythias. Calcium magnesium phosphate fertilizer or magnesium sulfate solution can be applied.
(12) Pest and Disease Damage
Fungal and other pathogen infections can cause leaf spot disease, leading to local necrosis, yellow spots or patches on the leaves, and in severe cases, whole leaves can turn yellow and fall off. Leaf mosaic patterns can appear after infection with mosaic virus, and infestations of scale insects or spider mites can also cause partial yellowing or even entire leaves to wilt and fall off. Prompt pesticide application is needed for control.
(13) Strong Stimulus
Using excessive concentrations of pesticides to control pests and diseases, exposure to toxic gases in the atmosphere, or suddenly watering with cold water during high temperatures can easily cause yellowing and scorching of the leaf tips or局部 areas, and even cause the whole plant to wither and die.
