Don't panic if your roses turn yellow in the fall; it might just be a false alarm!
Many gardening enthusiasts have recently encountered the issue of yellowing leaves on their roses. Today, I'll analyze the reasons why roses may turn yellow in the fall.
Analysis of Common Causes for Yellowing Leaves on Roses in the Fall
The issue of yellowing leaves can occur at any stage of rose growth. Some yellowing leaves are caused by management issues, such as fertilizer damage. Roses often experience a large number of yellow leaves during two periods: late spring and early fall. Why do roses easily turn yellow when first entering fall? There are mainly four reasons.
1. Heatstroke caused by humidity
At the beginning of fall, the weather is still quite warm, and in many regions, there is a lot of rain after entering fall. The combination of humidity and heat can easily cause roses to become root-bound, resulting in a large number of yellow leaves in a short period.
However, this kind of root-binding is usually not very serious. By controlling water intake and as fall temperatures decrease, the roses can naturally recover. Therefore, when you find that roses turn yellow after rain in the fall, there is no need to worry too much. Just clean up the yellow leaves, spray fungicides in a timely manner to prevent black spot disease, and ensure the potting soil does not accumulate water.
2. Drought

Autumn is a season prone to drought, especially for potted roses. Because after entering fall, there may be consecutive days of rainy weather, making the surface of the potting soil look dry and it's easy to become complacent about watering during the cloudy and rainy days.
After several days without watering, suddenly when the weather clears up, you may notice many potted plants showing signs of water deficiency by noon. If water is not replenished in time, it may cause a large number of old leaves to wither.
3. Seasonal Change
Both evergreen and deciduous plants go through a process of replacing old leaves with new ones, and this is particularly noticeable in roses during the fall.
