What to Do When Ivy Leaves Turn Black
Today's tip sharing: How to deal with blackened ivy leaves and an introduction to the causes of blackening in green plants and flowers. Next, the editor will introduce to everyone.
Ivy is a common ornamental leaf pot plant. If the leaves turn black, you need to first determine the cause and then take corresponding measures for different causes. The reasons for blackened ivy leaves include high temperature and poor ventilation, low temperature frostbite, unsuitable soil, excessive watering, excessive sun exposure, fertilizer damage, and pest and disease damage. Let's talk about how to deal with blackened ivy leaves.
1. Caused by High Temperature and Poor Ventilation
Ivy thrives in an environment of 15 to 24°C. High temperatures can easily cause the leaves to turn black, especially in environments with poor ventilation and high temperatures. After watering, the soil becomes humid and hot, which can lead to root rot. It is necessary to move the ivy to a suitable, well-ventilated, and cool environment for maintenance, cut off the blackened leaves, and clean up the withered branches and leaves.
2. Caused by Low Temperature Frostbite
In winter, low temperatures can cause frostbite or damage to ivy, resulting in blackened leaves. Immediate measures should be taken to keep warm, and the potted plant should be placed in an indoor environment with a temperature above 5°C for maintenance.
3. Caused by Unsuitable Soil and Water
Soil compaction can cause ivy leaves to turn black. Poorly aerated soil can lead to prolonged soil moisture. It is necessary to loosen the soil appropriately, and if the soil conditions are difficult to improve, it is advisable to change the pot and soil at the right time and extent.
Excessive watering, especially in high summer temperatures, can lead to overly moist pot soil, causing the ivy leaves to turn black. In this case, water should be applied only when the pot soil is dry, keeping the soil slightly moist.
4. Caused by Sunlight Exposure
Ivy prefers a semi-shaded environment and is also suitable for growing in an environment with plenty of scattered light but no direct sunlight. Prolonged exposure to sunlight or strong sunlight in summer can cause the leaves to dry and turn black. The location of the potted plant needs to be changed immediately, and if grown outdoors, proper shading is required.
5. Caused by Fertilizer Damage
Improper fertilization can cause ivy leaves to turn black. Fresh fertilizer, high fertilizer concentrations, or fertilizer contacting the roots can easily cause root damage. In this case, it is necessary to immediately flush the fertilizer with water. For potted plants, the roots can be gently rinsed with water after removing the pot, and then repotted after the soil dries. Also, note that in summer, as the growth of ivy slows down, fertilization must be reduced.
6. Caused by Diseases and Pests
If the leaves of ivy turn blackish-brown, it may be caused by diseases such as blight and gray mold. Black leaves should be removed promptly, and fungicides should be sprayed for prevention and control, with appropriate watering. If the sooty mold is caused by scale insects, physical removal or chemical pesticides should be used to eliminate the pests.
