What are the reasons for the yellowing of the bottom leaves of roses?
The yellowing of the bottom leaves of rose plants may be caused by factors such as soil conditions, watering and fertilizing, lighting, and diseases and pests. Rose plants cannot grow in a long-term humid environment. Generally, they should be placed in a well-ventilated environment to grow normally. When yellowing occurs, the cause should be identified based on the specific situation and dealt with promptly.
Watering roses should follow the principle of watering when the soil is dry and wet. If too much water accumulates in the soil and the plant cannot absorb it, root rot may occur over a long period, leading to the yellowing of the bottom leaves of the rose plant. Therefore, watering should be moderate, and the next watering should be done only when the soil is completely dry.
1. -- Poor Ventilation --
When the rose plant grows too densely without timely pruning, the ventilation between the leaves becomes poor. Some leaves that grow in a moist environment for a long time are prone to yellowing. Appropriate pruning of the plant should be done to maintain leaf spacing and place the plant in a well-ventilated environment for care.
2. -- Insufficient Lighting --
Roses cannot grow under strong sunlight, but adequate lighting is also very important for the plant. Lighting provides the conditions needed for photosynthesis. If the plant grows in an environment with insufficient lighting for a long time, it cannot perform photosynthesis normally, and the surface of the leaves will turn green.
3. -- Disease and Pest Invasion --
Usually, fungal diseases and red spiders are the most common pests that attack roses. Pay attention to whether small spots appear on the surface of the rose leaves, which are red, purple, or brown. If so, the bottom of the month has been infected with a fungal disease. The infected leaves should be promptly pruned and the soil should be kept well-drained.
