The reason why rose leaves turn yellow and have spots

The reason why rose leaves turn yellow and have spots

1. Excessive watering

The leaves of the rose begin to turn yellow and develop black spots. It may be because you water it too much, causing problems with the roots. The health of the plant is threatened, and the leaves will also turn yellow and develop black spots. During maintenance, you must pay attention to the application of water. It should not be too much and the frequency should not be too high. If you find that you have watered too much, you can drain the water in time.

2. Pot soil reasons

If the maintenance time is too long, the soil in the pot will become compacted, making it difficult for the roots of the plant to breathe, which will affect the growth of the plant. You can loosen the soil in time, or poke a few holes on the surface of the potting soil to ensure that the roots are breathable.

3. Excessive fertilization

It likes fertilizer, but the fertilizer should not be too much or too concentrated, otherwise the plant will not be able to bear it and large areas of yellowing will appear, and black spots will appear in severe cases. If this happens, you need to stop fertilizing immediately. If it is too serious, you can water to dilute the concentration.

4. Infections and diseases

It is not very disease-resistant and is often infected by diseases, which not only causes the leaves to become stiff, but also cause yellowing and black spots. You can spray pesticides for prevention and control, and pay attention to ventilation on a daily basis.

5. Too much light

If the leaves are accidentally exposed to strong light during maintenance, they will suffer from sunburn and black spots. You can first change the maintenance position and expose it to a diffuse light environment.
