Yellowing Rose Leaves: Master "4 Points", and the Leaves Will Be Greasy, Shiny, and the Flowers Will Bloom Beautifully and Fragrantly
Actually, if you enjoy gardening and like ornamental plants, it's really indispensable to have a pot or two of rose bushes on the balcony. There are many varieties, which can be planted in the ground or in pots. Some have bright flowers, others have strong fragrance, and various flower shapes. Among all these, rose bushes seem to be the most beloved, relatively easy to care for, and there are also micro roses, climbing roses, and cut roses, which are indeed very beautiful. Whether it's pink, red, or other colors, they are all very beautiful. So, when we are growing potted rose bushes, we may notice that the leaves are turning yellow. What exactly is going on, and how should we deal with it?
1. Yellowing or Falling Leaves Caused by Low Temperature
If you usually grow potted rose bushes or rose seedlings that are always green and lush, but the leaves turn yellow in winter due to low temperatures, it is normal, especially for old leaves. This is especially common when the temperature is around zero degrees, and yellowing is more normal. In spring, new leaves will sprout. At this time, not only yellowing but also leaves may easily fall off, which is also normal for old leaves.
2. Yellowing Leaves Caused by Diseases and Pests
If the potted rose bushes at home have not only old leaves turning yellow but also young leaves, you can check the back of the leaves to see if there are any diseases or pests, the most common being red spiders. If so, spray pesticides promptly and maintain a well-ventilated and sunny growing environment.
3. Yellowing Leaves Caused by Excessive Water
Especially for potted rose bushes kept indoors or in a closed balcony with poor ventilation, if watered, the evaporation is slow, and the soil is too wet, which can also cause yellowing leaves. In this case, it is necessary to increase ventilation. If the outdoor temperature is not too low, you can place it outside for a period, and the yellowing situation will naturally improve.

Especially in summer, when the weather is hot and the temperature is high, if there is no ventilation and the soil is too wet, it is very easy to have yellowing leaves, or even lose all leaves and become a bare stem. In summary, placing it in a well-ventilated area, exposing it to the sun, and controlling watering will restore normal growth.
4. Yellowing Leaves Due to Lack of Fertilizer or Over-fertilization
In very poor and nutrient-depleted soil, or if the potting soil has not been changed for several years, lack of nutrition and fertilizer can also cause yellowing leaves. Therefore, supplementing fertilizer in time is the solution.
