【Solutions for Yellowing Rose Leaves】
<1, Environmental Change>
When you have just bought a potted rose, the rose has changed its environment and may show yellowing leaves due to discomfort.
Solution: When roses have this phenomenon, there's no need to worry too much. Reduce the degree of environmental change and let the rose adapt gradually. Over time, the growing environment will stabilize.
<2, Improper Watering>
When watering roses too much, the leaves become dark yellow and lackluster, the stems show no significant changes, the branches are thin and yellow-green, the new shoots wither, and the young leaves turn yellow.
Solution: If the lower leaves of the rose have turned yellow, stop watering immediately. Loosen the soil around the potted rose to allow the water to evaporate quickly. Water again when the soil is dry, but do not water too much each time.
<3, Insufficient Sunlight>
When roses are placed in a shaded environment for a long time, the leaves do not receive enough sunlight to produce chlorophyll, causing the entire plant's leaves to turn yellow and fall off.
Solution: Insufficient sunlight will cause yellowing leaves, and in severe cases, the whole plant may rot and die. Move the plant to a well-lit area, but avoid direct sunlight.
<4, High or Low Temperature>
