What Causes the Yellowing of Desert Rose Leaves
This topic introduces the reasons for the yellowing of desert rose leaves and related topics such as the causes and solutions for flower cultivation, as follows:
When growing desert roses, their leaves may also turn yellow. After investigating for a period, I found that the yellowing of their leaves is mainly caused by the following four reasons. Today, let's learn how to prevent and treat the yellowing of their leaves.
First Point: Root Rot Leading to Yellowing of Desert Rose Leaves
Solution: Over-fertilization and excessive watering can cause root rot. In managing this type of flower, I found that severe withering of the plant is caused by excessive fertilizer, while a foul smell indicates overwatering leading to root rot. To treat it effectively, you must剪除 the affected parts early, cut them off promptly, disinfect them, and change the pot to restore the plant's growth momentum.
Second Point: Pest and Disease Leading to Yellowing of Desert Rose Leaves
Solution: The fragrance of the desert rose is likely to attract insects, such as scale insects, which are common pests that cause leaf yellowing and falling off. Using pymetrozine or fenvalerate emulsion can solve this problem, but the concentration must be controlled when preparing the pesticide to avoid adverse effects. I also found that leaf spot disease can cause leaf yellowing during the growth period, which can be treated with metalaxyl.
Third Point: Improper Fertilization and Watering Management Leading to Yellowing of Desert Rose Leaves
Solution: During the growth period, you can determine whether the yellowing is caused by excessive or insufficient water and fertilizer based on the plant's growth momentum. If the leaves are green before watering and fertilizing and turn yellow afterward, it is likely due to excess. Timely watering and fertilization can improve the plant's growth momentum when the leaves turn yellow.
Fourth Point: Improper Environment Leading to Yellowing of Desert Rose Leaves
Solution: Appropriate lighting and temperature are required during the growth period to ensure that the leaves are green and the plant grows vigorously. For example, low temperatures in the growing environment can reduce the plant's ability to absorb nutrients, leading to yellowing leaves. Insufficient lighting can also slow down the conversion rate of chlorophyll in the leaves, causing them to turn yellow.
In summary, temperature and lighting should be adjusted according to different seasons. In the summer, when temperatures are high and sunlight is strong, the plant can be placed in an air-conditioned room, but preferably in a sunny area to ensure both temperature and adequate lighting, allowing the desert rose to grow better. The above are the reasons for the yellowing of desert rose leaves during the growth period and the corresponding solutions. To maintain its ornamental value, a suitable growing environment is very important for the plant.
