1、 Pest control

The yellow leaves of bamboo may be infected with pests, such as red spider and aphid. The pests will absorb juice and cause the leaves to turn yellow and dry. If it is determined that it is an insect pest, the first person can remove the insects, clean the leaves with a brush in time, cut off and destroy the Yellow branches and leaves, and spray imidacloprid water solvent, deltamethrin emulsion and other insecticides on the bamboo. In order to avoid the re infection of bamboo with pests, ventilation measures should be taken to avoid the muggy and humid growth environment

2、 Rational fertilization

Bamboo needs nutrients for normal growth. If there is insufficient fertilization and lack of nutrients, it will also lead to yellow leaves. At ordinary times, sufficient base fertilizer should be applied, and thin fertilizer can be applied regularly in the growth stage to meet the growth needs and ensure the green luster of the leaves

3、 Sunscreen and shading

Bamboo needs light to grow, but it can't stand strong light exposure. If exposed to the hot sun, the leaves will turn yellow and dry. Sun protection measures can be taken for bamboo to block a certain amount of strong light, cut off yellow leaves, and promote bamboo to sprout again and grow new leaves

4、 Control moisture

Bamboo is not resistant to waterlogging. If it is watered too much, the roots cannot absorb all the water, resulting in ponding in the roots and yellow leaves. We can control the water for bamboo in time, adhere to the watering principle of seeing dry and seeing wet, and loosen the soil in time to discharge the water in the soil
