The causes and treatments of yellow leaves of roses

1. Flower soil reasons

1. Reason: The yellow leaves of roses may be because the soil in which they are grown is not suitable for their growth. It likes loose, thick, slightly acidic flower soil with a pH between 6.2-6.8. If the soil in which it is grown is not breathable enough or is too alkaline, it will grow poorly and have yellow leaves.

2. Treatment method: first take it out of the old soil, then use scissors to cut off the yellow leaves and rotten roots on the plant, and then plant it in a weakly acidic and well-breathable culture soil for maintenance.

2. Reasons for watering

1. Reason: Rose needs an appropriate amount of water to help grow. If you water it too much or don't water it for a long time, its leaves may turn yellow.

2. Treatment method: If the plant is overwatered, you can raise the flowerpot, dry the soil in it, and then reduce the number of watering. If there is too little watering, you can increase the frequency of watering to provide it with water and help it recover.

3. Reasons for fertilization

1. Reason: If you fertilize it too frequently while raising it, it will cause fertilizer damage and yellow leaves will appear. If no fertilizer is applied for a long time during cultivation, its leaves may turn yellow.

2. Treatment method: If too much fertilizer is applied, you can use clean water to refresh the flower soil and wash it clean. Then put it in a ventilated place to dry. If too little fertilizer is applied, you will need to apply some fertilizer to provide nutrients.
