What to Do When the Leaves of Dichroa jasminoides Turn Yellow
Dichroa jasminoides is favored for its unique flower color, but when the leaves show abnormal yellowing, it often leaves caretakers at a loss. This article systematically analyzes the five most common causes and provides scientific solutions to help you quickly restore plant vitality.
Imbalance in Water Management
Symptoms of Overwatering
Young leaves appear dark yellow and lack luster, the root system is underdeveloped and yellowish-green, and the soil remaining moist for too long causes root suffocation. It is recommended to use breathable containers like clay pots and test the soil 3cm deep for moisture before watering each time.
Symptoms of Underwatering
Old leaves dry up and fall off from the bottom up, while new leaves may grow but the overall plant will shrink. In spring and autumn, maintain a watering cycle of every 3-5 days, and in high summer temperatures, supplement with foliar sprays in the morning and evening.
Abnormal Nutrient Supply
Plan for Fertilizer Burn Treatment
When brown burn spots appear at the leaf tips, immediately rinse the potting soil with water three times in a row. It is recommended to switch to slow-release fertilizer, applying 5-8 pellets every quarter to meet the plant's needs.
Measures for Correcting Fertilizer Deficiency
Plants that have not been repotted for two years need to undergo root pruning, retaining the main roots about 15cm long. During the growing season, supplement with phosphorus-potassium liquid fertilizer monthly, diluted at a ratio of 1:1000.
Key Points for Light Control
Ensure at least 4 hours of scattered light daily, and use a shade net for protection between 11:00-15:00 in summer. In winter, the plant can tolerate full sunlight, and plant growth lights can be used for 2 hours daily when light is insufficient.
What to Do When the Leaves of Dichroa jasminoides Turn Yellow
Soil pH Adjustment
Regularly check the soil pH level, maintaining it between 5.5-6.5. Apply a solution of ferrous sulfate (0.5g in 500ml of water) monthly, combined with pine needle soil to improve the matrix, effectively preventing iron deficiency yellowing.
Temperature Adaptation Strategy
Maintain an ideal growth temperature of 18-28°C, and when temperatures exceed 32°C, enhance ventilation and sprinkle water on the ground to cool. When the room temperature in winter drops below 10°C, it is recommended to use a thermal film and reduce watering to once every half month.
By following the above systematic care plan, more than 90% of yellow leaf issues can be improved within 2-3 weeks. It is recommended to establish a care log, recording each treatment measure and plant changes, gradually mastering the growth patterns of Dichroa jasminoides.
