The yellowing of jasmine leaves may be caused by various reasons, including soil problems, insufficient light, improper watering, improper fertilization, and pests and diseases. To address these issues, the following measures can be taken: 1. Check the soil
Soil pH: Jasmine prefers acidic soil. If the soil is weakly alkaline, it can cause the leaves to turn yellow. Regular use of ferrous sulfate solution or alum fertilizer water can be used to adjust the acidity and alkalinity of the soil, keeping it within an appropriate range.
Soil quality: Ensure that the soil is loose, breathable, and has good drainage. If the soil is compacted or poorly drained, it is necessary to replace the soil or carry out soil improvement in a timely manner. 2. Improve lighting conditions
Light demand: Jasmine is a light loving plant that requires sufficient light for photosynthesis. If left in a dark place for a long time, it can cause the leaves to turn yellow. Jasmine should be placed in a place with sufficient scattered sunlight for maintenance, avoiding prolonged exposure to dark environments.
Avoid direct exposure to sunlight: Although jasmine requires light, it is also important to avoid direct exposure to sunlight during high temperatures in summer to prevent leaf burns. 3. Reasonable watering
Watering principle: Jasmine has a high demand for water, but soil that is too wet or too dry can cause yellowing of leaves. The watering principle of 'see dry, see wet' should be followed, that is, when there is a shortage of water, watering should be done thoroughly.
Seasonal adjustment: The amount and frequency of watering in different seasons should be adjusted accordingly. Spring and summer require a large amount of water, so watering should be increased appropriately; In autumn and winter, it is necessary to reduce the amount of watering and keep the soil slightly moist. 4. Correct fertilization
Fertilization amount: Excessive or insufficient fertilization can cause jasmine leaves to turn yellow. The principle of frequent application of thin fertilizer should be followed to avoid applying too much fertilizer at once.
Fertilizer selection: Suitable fertilizers for jasmine growth should be chosen, such as compound fertilizers with balanced nutrient elements such as nitrogen, phosphorus, and potassium. 5. Prevention and control of pests and diseases
Regular inspection: Regularly inspect the leaves and branches of jasmine, and take timely measures to prevent and control diseases and pests.
Prevention and control measures: For common pests and diseases such as spider mites and aphids, pepper water or specialized insecticides can be sprayed for prevention and control. Meanwhile, maintaining good ventilation in plants can also help reduce the occurrence of pests and diseases.
To address the issue of yellowing of jasmine leaves, solutions can be taken from aspects such as soil, light, watering, fertilization, and pest control. Through reasonable maintenance and management measures, jasmine can restore healthy growth and bloom beautiful flowers.
