Reasons why ivy leaves turn red

Reasons why ivy leaves turn red

1. Frostbite

Reason: Ivy is an evergreen plant. Its leaves are generally evergreen all year round and rarely turn red. If this happens in winter, it may be because the temperature is too low and it cannot withstand the low temperature. Too low temperature will cause frostbite, causing the leaves to turn red. Measures: The redness of leaves will affect the ornamental value, and long-term low temperatures may harm its growth. In winter, it can be moved indoors for maintenance and the temperature can be adjusted to above 10℃.

2. Infections and diseases

Cause: If the leaves appear an unhealthy red color, they may be infected with leaf spot disease. When the disease first occurs, small spots appear on the leaves, which then expand into larger spots with red edges. Measures: If this is the case, timely treatment is needed to prevent the disease from spreading and worsening. The infected plants should be removed and destroyed in time, and the cultivated soil should be treated with formalin solution, which can sterilize it.

3. Sun exposure

Reason: The redness of ivy leaves may also be due to exposure to sunlight, which causes the leaves to turn red under the stimulation of light. Measures: Provide sunlight correctly and block strong light in time.
