Rosemary flowers are small and beautiful, making them a plant with high ornamental value. However, improper cultivation methods can lead to leaf yellowing. There are many reasons for the yellowing of rosemary leaves, but the main causes are usually five: irrigation issues, improper fertilization, lack of sunlight, a closed environment, and pest and disease damage.
No matter what, the yellowing of leaves is closely related to our daily management and environment. Sometimes, multiple factors can act together to cause yellowing.
Reasons for Yellowing of Rosemary Leaves
1. Low temperature
Rosemary is relatively cold-tolerant, but if it cannot be well controlled for temperature during winter, the plant may freeze and get injured. When rosemary is frozen, its leaves tend to turn yellow and fall off.
2. Too much watering
Rosemary is a type of succulent plant, which is drought-resistant but afraid of waterlogging. If it is watered frequently during maintenance, leading to excessive water, the plant cannot absorb it all. Over time, this can hinder growth and breathing, leading to yellowing and falling leaves.
3. Too much sunlight
Rosemary enjoys sunlight, but it fears intense sun exposure. If it is kept under strong sunlight for a long period during maintenance, it can get sunburned, resulting in yellowing leaves and even falling.
Methods to Remedy Yellowing Leaves
First, dilute the fertilizer in rosemary by increasing watering. However, if the yellowing is severe, it is necessary to change the soil, replant with new potting soil, and reduce the frequency of fertilization.
After repotting, avoid frequent watering and do not place it directly under sunlight for maintenance. Instead, keep it in a place with scattered light for a period. Once the yellowing issue is缓解ed, choose to place it outdoors in the sunlight or indoors in a well-ventilated area based on the weather and climate conditions. Also, pay attention to the surrounding hygiene and spray appropriate pesticides to prevent pest and disease infections.
