As winter approaches, many flower enthusiasts may notice that the leaves of their Michelia plants are gradually turning yellow, which undoubtedly brings us who love Michelia a lot of trouble. What are the reasons for the yellowing of Michelia leaves in winter? How can we prevent and treat it? This article will answer these questions for you one by one.
Reasons for the Yellowing of Michelia Leaves in Winter1. Insufficient lighting
Michelia is native to tropical and subtropical regions and prefers a warm, humid, and sunlit environment. In winter, due to the short day length and weak light, Michelia leaves turn yellow.
2. Low temperature
Michelia is not cold-resistant. Low temperatures in winter can slow down its growth or even cause yellowing of the leaves.
3. Improper watering
In winter, Michelia's water requirement decreases. If watered too much, it can easily lead to root rot, which in turn causes the leaves to turn yellow.
4. Improper fertilization
In winter, Michelia's demand for fertilizer is relatively low. If fertilized too much, it can easily lead to excessive soil fertility, thus causing the leaves to turn yellow.
5. Pest and disease infections
In winter, Michelia is susceptible to pests and diseases such as scale insects and red spiders, which can cause the leaves to turn yellow.
Prevention and Treatment of Yellowing Michelia Leaves in Winter1. Increase lighting
Place Michelia in a well-lit area, such as near a window, to ensure it can absorb adequate sunlight.
2. Control temperature
Keep the indoor temperature above 10℃ in winter to avoid low temperatures affecting the growth of Michelia.
3. Water properly
In winter, Michelia's water requirement decreases. Watering should follow the principle of "watering when dry and stopping when wet," avoiding waterlogging.
4. Fertilize reasonably
In winter, Michelia's demand for fertilizer is relatively low. You can reduce the amount of fertilizer or choose a low-nitrogen, high-phosphorus, and potassium compound fertilizer.
5. Control pests and diseases
Regularly inspect Michelia for pests and diseases and take timely measures when found, such as using insecticides or pyrethrum.
The reasons for the yellowing of Michelia leaves in winter are multifaceted. We should take corresponding preventive and treatment measures based on specific situations. With proper care, Michelia can still bloom beautifully in winter. I hope this article is helpful to you.
