What about the yellowing of bamboo leaves on the back of the latest tortoise?

There are many reasons for the yellowing of bamboo leaves on tortoise back. If you can cut off the yellow leaves after they are found to be yellow, and then place them in a ventilated place, the reasons for yellowing bamboo leaves are generally soil discomfort, too much or too little watering, too strong or dark light, too low temperature, too little fertilization, poor ventilation and so on. Let's take a look at what to do with the yellowing of tortoise bamboo leaves.

Yellowing of leaves caused by soil discomfort

[cause of yellowing] Phyllostachys pubescens is originally a parasitic plant, and its developed root system is fleshy root, which requires high porosity and permeability of soil. Clayey and micro-clayey soil will affect the growth of root system in varying degrees. If the soil permeability is not good or does not change soil for a long time, it may cause soil consolidation and affect the respiration of Phyllostachys pubescens, resulting in poor growth and yellowing of leaves.

[solution] for family potted bamboo, the cultivated soil can be mixed with 2 parts of mature loess, 1 part of honeycomb coal ash and 1 part of chicken manure, which can not only ensure the air permeability of potted soil, but also meet the fertilizer requirements for growth.

Yellowing of leaves caused by inappropriate watering

[cause of yellowing] too much or too little watering will cause the leaves of the tortoise back bamboo to turn yellow, more water will cause the rotting root phenomenon of the tortoise back bamboo, and less water will make the plant grow badly due to lack of water, both of which will cause the yellow leaf phenomenon of the tortoise back bamboo.

[solution] the tortoise back bamboo should be watered regularly and thoroughly at one time to keep the surface of the basin soil slightly dry. when the air is dry, sprinkle water on the environment and the leaves of the tortoise back bamboo.

Yellowing of leaves caused by discomfort of light

[cause of yellowing] excessive light or too much light will cause the leaves of the tortoise back bamboo to turn yellow, and the dark tortoise back bamboo can withstand shade, but placing the tortoise back bamboo in a shaded environment for a long time will affect photosynthesis and make the leaves yellow. At the same time, the tortoise back bamboo can not be placed in the strong light, the strong light will cause the leaves of the tortoise back bamboo to burn and turn yellow.

[solution] the tortoise back bamboo should pay attention to shade in summer, and it is best to give the tortoise back bamboo some scattered light.

Yellowing of leaves caused by low temperature

[cause of yellowing] the suitable temperature for the growth of Phyllostachys pubescens is 20: 25 ℃, the temperature at night in winter is not lower than 10 ℃, the mature plants can tolerate 5 ℃ in a short time, and freezing injury is easy to occur when the temperature is lower than 5 ℃, which causes the leaves of Phyllostachys pubescens to turn yellow.

[solution] it is necessary to keep the roots of the tortoise-backed bamboo warm in winter to enhance the cold resistance of the plant, but do not put the tortoise-backed bamboo directly on the radiator or next to the air conditioner.

Yellowing of leaves caused by too little fertilization

[cause of yellowing] Iron is a necessary raw material for plants to synthesize chlorophyll. If there is not enough iron in soil or fertilizer, it will affect the synthesis of chlorophyll, resulting in chlorosis and yellowing of leaves.

[solution] if the leaves are yellowed due to iron deficiency, alum fertilizer water or 0.1-0.3% ferrous sulfate solution should be applied.

Yellowing of leaves caused by poor ventilation

[cause of yellowing] when the ventilation is not good, it will cause the stuffy yellow of the leaves of tortoise back bamboo.

[solution] to keep the room well ventilated, you can also put the turtle-backed bamboo indoors during the day and move outside at night.
