If you want to grow a good pear, scrape its bark in winter.

1. Symptoms Jujube Mad Disease, also known as witches' broom disease, broom disease, fire dragon disease, is a devastating disease. Fruit growers call it "mad jujube tree" or "male jujube tree". Both aboveground and underground parts of jujube trees can be infected. The aboveground infection was mainly characterized by floral organ degeneration, bud germination and abnormal growth, resulting in clusters of branches and leaves, extension of the hanging end of jujube, bright veins, yellowing or curling of tender leaves, and occasionally ear-shaped leaves. The disease in the underground part is mainly manifested as a cluster of roots and tillers. The whole flower organ of the diseased tree was degenerated into a vegetative organ, and the flower stalk was prolonged, which was 5-7 times longer than that of the healthy flower.
