1. Reasons for leaf curling1. Lack of water: If there is no watering for a long time during management, the leaves will become dull and turn yellow. When there is severe water shortage in the later stage, it will start to curl. This is the state it shows in order to protect itself from water loss. If you don't replenish water in time, the leaves will easily fall off. It is important to water as soon as possible, keep it moist during the growing season, and be sure to water it thoroughly when it is dry, and also sprinkle water frequently. 2. Infection by pests: If curling occurs occasionally, it is mostly due to infection by pests. Common insect pests are scale insects and red spiders, which should be checked and dealt with as soon as possible. If it is infected with scale insects, spray it with scale killer. If it is red spider mites, just remove the infested leaves directly. 3. Infection by diseases: If its leaves first develop spots and then curl up, it is mostly because of infection by bacteria and diseases. Common diseases are leaf spot and brown spot, both of which can cause the leaves to lose water and curl. The medicine must be sprayed as soon as possible. You can choose 800 times of zinc and manganese sen and use it to irrigate the roots, which will have a better effect. 2. Can it survive if all the leaves fall off?To see if it can still survive after losing all its leaves, you need to check its root system. If the root system is relatively healthy and fresh, it can survive. However, if you change the management method, water and fertilize correctly, and provide a suitable growing environment, it will slowly recover. If its roots have dried up and died, there is no possibility of saving it. |
