What Happens When the Leaves of a Rose Drop at the Touch When They Are Dry?
This article provides an introduction to why the leaves of a rose plant wither and fall off at the touch, as well as some small green plant maintenance tips for dealing with the problem of rose leaves falling, as detailed below:
Roses are beautiful and bloom throughout the year, earning the title of "Queen of Flowers." They can be grown as ornamental plants or used in medicine, and therefore are widely cultivated. During cultivation, it is common to encounter the problem of rose leaves withering, which can be caused by various reasons such as excessive watering, insufficient light, poor ventilation, high temperatures, pest infestations, and improper fertilization. The following are specific analyses and some coping methods.
1. Excessive Watering
Roses thrive in a warm and humid environment, but excessive watering can lead to waterlogging, causing root rot, with the soil being moist while the leaves dry out, resulting in yellowing and withering symptoms.
Solution: Pay attention to water control, reduce the amount and frequency of watering, and grasp the balance. After a few weeks, when the rose has recovered, normal watering can resume. Potted roses can also be moved to the sun to evaporate excess water.
2. Insufficient Light
Roses love sunlight, and long periods in a shaded environment can prevent them from getting enough light, causing the leaves to dry out and turn yellow, affecting normal growth.
Solution: Move the rose to a location with ample light, preferably ensuring it gets 7-9 hours of sunlight per day. After absorbing enough sunlight, the yellowing of the leaves will naturally improve.
3. Poor Ventilation
When roses are in a relatively enclosed and unventilated environment, they cannot get enough oxygen. Poor air circulation leads to poor air quality, which can cause the leaves to turn yellow.
Solution: Place the rose in a well-ventilated environment for cultivation, and it is best to open the windows for ventilation in winter to create a fresh and flowing air environment.
4. High Temperature
In the hot and humid summer environment, the evaporation of water from roses accelerates. If the leaves do not have enough water, they will become wilted and dry.
Solution: Move the plant to a shady spot to mitigate the adverse effects of high temperatures, or you can choose to spray some water on the leaves to keep them moist and cool the plant.
5. Pest and Disease Infestation
Diseases and pests can cause the leaves of roses to wither and turn yellow, such as powdery mildew and scale insects, which can lead to leaf wilt and yellowing, and if not treated promptly, may even cause plant death.
Solution: For pests and diseases, it is important to apply the right treatment based on the symptoms. For common powdery mildew, the plant can be moved to a clean environment for cultivation. For pests and diseases, the appropriate drugs should be used and the affected leaves should be cut off.
6. Improper Fertilization
Fertilization is an important part of rose cultivation. Too much or too little fertilization can affect the health of the plant, which can manifest as leaf withering.
Solution: Fertilize in moderation. If too much fertilization has occurred, you can add water to the soil to dilute it or change the soil directly. If too little fertilization has occurred, you need to increase the amount of top dressing to ensure that the rose has enough nutrients for growth.
The above provides an explanation of why rose leaves wither and fall off at the touch, along with methods to deal with the problem of rose leaves falling, which can be used as a reference for everyone.
