Many rose enthusiasts encounter the issue of yellowing in old rose leaves during maintenance. This not only affects the overall aesthetics of the rose but may also impact its growth. What should be done about yellowing old rose leaves? This article will provide you with detailed answers.
Reasons for the Yellowing of Old Rose Leaves1. Insufficient Water
Roses enjoy water, but excessive or insufficient water can lead to yellowing of old leaves. If watering is not timely, the rose roots cannot absorb enough water, resulting in leaf yellowing.
2. Improper Fertilization
Both excessive and insufficient fertilization can cause yellowing of old rose leaves. Excessive fertilization can lead to high soil salinity and root damage, while insufficient fertilization results in inadequate nutrition supply, affecting rose growth.
3. Insufficient Light
Roses thrive in sunlight, and long-term exposure to dark environments can lead to poor growth and yellowing leaves.
4. Pest and Disease Infections
Roses are susceptible to pest and disease attacks, such as aphids and red spiders. These pests extract nutrients from the rose, leading to yellowing leaves.
Methods to Deal with Yellowing Old Rose Leaves1. Water Moderately
Keep the soil moist but not waterlogged based on the rose's growth habits. When watering, ensure thorough watering to avoid excessive water that could cause root rot.
2. Fertilize Properly
Fertilization should follow the principle of "frequent application of light fertilizer," avoiding excessive fertilization. You can choose a compound fertilizer with a balanced nitrogen-phosphorus-potassium ratio and apply it every 15 days.
3. Increase Sunlight
Move the rose to a sunny location, ensuring it gets at least 4 hours of direct sunlight daily. If conditions do not allow, you can use a plant growth lamp appropriately.
4. Control Pests and Diseases
Regularly inspect the rose leaves and deal with pests and diseases promptly. You can use insecticides and fungicides for prevention and treatment.
5. Prune Yellowed Leaves
Trim the yellowed parts of the old rose leaves to prevent the spread of pests and diseases. Ensure the cut surfaces are smooth to aid in healing.

2. Regularly loosen the soil to improve soil aeration, which is beneficial for root growth.
3. Plan the layout reasonably to avoid overcrowding of roses, which can affect ventilation and sunlight.
4. Strengthen pest and disease control to reduce their impact on roses.
