Uneven watering will also cause some leaves to wither.
2. Insufficient light Brazilian wild peonies prefer a sunny environment. If they are in the dark for a long time, their leaves will gradually turn yellow and fall off due to lack of light.
3. Improper application of fertilizer Excessive application of fertilizer or improper application of fertilizer will lead to excessive soil salinity, affecting plants 'absorption of water and nutrients, and then causing leaf loss.
4. Diseases and insect pests invade Brazilian wild peonies are vulnerable to pests such as aphids and red spiders. These pests will absorb nutrients from the plant, causing the leaves to turn yellow and fall off.
5. Environmental factors Environmental factors such as temperature and humidity will also affect the growth of Brazilian wild peonies. If the temperature is too high or too low, and the humidity is too high or too low, it may cause plants to lose leaves. Prevention and control measures for leaf loss of Brazilian wild peonies 1.

4. Regularly inspect plants to prevent and control pests and diseases, and take timely measures when pests and diseases are discovered. Pesticides, fungicides and other pesticides can be used for prevention and control. At the same time, pay attention to rotating the use of different types of pesticides to prevent pests from developing drug resistance.
5. Adjust environmental factors Reasonably adjust the temperature and humidity according to the growth needs of Brazilian wild peonies. When high temperatures in summer, ventilation can be appropriately increased to reduce indoor temperatures; when low temperatures in winter, warm measures can be taken.
Leaf loss of Brazilian wild peonies is a common problem. Understanding the causes and taking corresponding prevention and control measures can effectively solve this problem. I hope this article can provide help to growers and let your Brazilian wild peonies thrive.
