Jasmine leaves are wrinkled and curling downwards
Let's talk about the knowledge of green plants and flowers regarding the reasons why jasmine leaves are wrinkled and curling downwards and why they wither and fall off. Here is a detailed introduction below.
Jasmine flowers are pure white and fragrant, but sometimes, as爱好者 cultivate them, the leaves turn yellow and curl. What is the reason for this? Let's take a look together.
I. Too much sunlight
Jasmine prefers to grow in a semi-shaded environment. If the position where it is cared for has too much sunlight or is exposed to strong sunlight for a long time, prolonged exposure can cause the leaves to dehydrate and curl.
Solution: Move it promptly to a shady and diffused light area, avoiding continuous exposure to strong sunlight. Then spray the plant with water to keep it moist. Once the sunlight decreases, it will gradually recover.
II. Lack of water
Jasmine is suitable for growing in a humid environment. If the potting soil is dry for a long time, the branches and leaves will not receive enough moisture, leading to curling and wilting after some time. It may also turn yellow, dry out, and lose leaves, and in severe cases, even cause the plant to die.
Solution: Water promptly. When watering, it is recommended to use the immersion method to allow the roots to absorb water quickly. If watering from above, make sure water flows out of the bottom of the pot. During daily care, pay attention to watering once a day in summer and spray water mist on the plant 2-3 times during the day to keep it moist.
III. Fertilizer damage
Although jasmine likes fertilizer, it should not be fertilized too frequently or in excessive amounts at once, as this can lead to fertilizer damage. When the roots are burned by excessive fertilizer, the leaves will turn yellow and curl. An excessive amount of fertilizer that the plant cannot absorb in a short time will result in such conditions.
Solution: If using compound fertilizers or solid fertilizers, remove any excess fertilizer promptly and water more to reduce the concentration of fertilizer in the soil. When fertilizing, avoid using concentrated or uncomposted fertilizers.
IV. Pests and diseases
If there are aphids or mealybugs on the leaves of jasmine, they can cause the leaves to turn yellow. This is because the pests damage the leaves, absorb the sap, and densely cover the leaves, affecting their growth, which leads to leaf curling. Poor ventilation, dense foliage, and a dry or humid environment can all trigger pest infestations.
Solution: When jasmine is infected with pests or diseases, move it promptly to a well-ventilated outdoor area and then spray the plant with pymetrozine solution, which can effectively kill the pests.
