Causes and treatments for yellow rose leaves

1. Improper watering

1. Reason: Improper watering may cause its leaves to turn yellow. Too much watering will cause water accumulation at the roots and reduce the ability to absorb water; too little watering will result in less moisture in the soil. All of these will lead to less water absorption by the roots and yellowing of the leaves.

2. Treatment: If you water too much, you should reduce the amount of watering and place it in a cool place; if you water too little, you should increase the frequency and amount of watering.

2. Improper fertilization

1. Reason: Fertilizing too early, applying fertilizer at an inappropriate time, or choosing an inappropriate type of fertilizer may affect its growth, causing it to grow sluggishly and its leaves to turn yellow.

2. Treatment method: Fertilization should be applied in autumn and not just after planting. Fertilizers should not be too concentrated, and more dilute fertilizers and nitrogen-containing fertilizers should be applied. If individual plants grow small, you can apply a small amount of foliar fertilizer on the surface. If the plant has yellow leaves due to concentrated fertilizer, it is necessary to remove it from the pot, wash the roots and change the soil in time.

3. Plant Disease

1. Cause: Common rose diseases such as powdery mildew and rust will cause the plant to grow sluggishly, and these diseases may cause the leaves to turn yellow during the onset of the disease.

2. Treatment method: Spray the medicine in time to solve the disease. If powdery mildew occurs, you can spray triadimefon solution; if rust occurs, spray 800 times triadimefon, spray once a week, and spray for one month to cure it.
