Bamboo, also known as bamboo, is a perennial grass family plant. There are many types of bamboo, with upright culms and green leaves, which symbolize noble character and unyielding spirit, and are deeply loved by people. Many people like to plant bamboo in front of and behind their houses. So, in the process of planting, what is the reason for the yellowing of bamboo leaves? The country tune believes that the yellowing of bamboo leaves is mainly caused by the following reasons.
One, insufficient light
In the process of bamboo growth, it needs sufficient sunlight to allow the bamboo branches and leaves to photosynthesize and form chlorophyll. If the place where we plant bamboo has poor lighting, over time it will cause the leaves of the bamboo to turn yellow, which requires us to promptly transplant the bamboo to a place with good lighting for maintenance, such as in front of a shadow wall. At the same time, the yellowed leaves should also be cut off to avoid the loss of nutrients.
It should be noted that at noon in summer, the sun is strong, and bamboo is not tolerant of strong light, so a sunshade net needs to be set up for the bamboo to avoid the leaves being burned by strong light.
Two, improper watering
Bamboo likes water, and too much or too little watering can cause the leaves to turn yellow.
The correct way to water bamboo is: in summer, water the bamboo once a day. Summer watering can be done in the morning or evening and should not be done at noon because the ground temperature is high at noon in summer, and the water flowing over the ground will heat up, which may scald the bamboo roots and cause yellow leaves. Water every 3-5 days in spring and autumn, and every 15 days in winter.
Although bamboo likes water, watering should not be too frequent. If the bamboo is waterlogged for a long time, it will also cause the leaves to turn yellow. In this case, stop watering in time, cut off the yellow leaves, observe for a period of time, and water again when the soil is completely dry.
Three, pests and diseases
When bamboo has pests and diseases, light yellow spots will appear on the front of the leaves, which will expand into elliptical spots after a few days until the leaves turn completely yellow. This phenomenon is that the bamboo has contracted pests and diseases, and pests such as red spiders and aphids will absorb the sap of the bamboo, causing the leaves to turn yellow. We should promptly cut and destroy the yellow bamboo leaves and spray pymetrozine or deltamethrin emulsion. After spraying once, spray again after 7 days to ensure that all pests are eliminated.
