Ivy is very common in our daily life. Because it can purify the air and is highly ornamental, many people will keep one or two pots of it at home.

What is the problem with ivy leaves turning black?

1. Botrytis cinerea

When ivy is infected with gray mold, water-soaked black or gray spots will appear on the edges of the leaves. In severe cases, a gray mold layer will form, causing the plant to wilt or even die. The cause of the disease is related to high temperature and high humidity.

2. Disease

When ivy is infected with the blight, most of the leaves turn brown and rot, or the base of the stems and tender nodes become dark green and water-soaked, become soft and shrink, and then turn brown to dark brown, and the branches and leaves above the diseased part wither.

How to solve the problem of ivy leaves turning black

1. Clean up all the diseased leaves and branches, and then improve the environment to avoid excessive moisture. The air should not be too humid, and the soil should not be waterlogged.

2. Improve ventilation and avoid keeping it in a confined space. Also, be sure to apply some fungicides, such as the common carbendazim or thiophanate-methyl. You can also use the more effective thiophanate-methyl or mancozeb solution.

What to do if ivy branches wither

First of all, the ivy should be pruned. This plant grows rapidly, but the area of ​​the potting soil is limited. The faster it grows, the harder it is to replenish the moisture in the soil. If your ivy has dead leaves and empty branches, you should decisively prune off the empty branches and dead leaves to reduce the leaf density. The purpose of doing this is to reduce the water replenishment pressure on the ivy and give it a buffer period for self-repair.

Then, in the future, you must do a good job of replenishing water in time, and never let it dry out. If the air at home is dry, it is best to spray it once in the morning and evening. Finally, you can fertilize the ivy with nitrogen fertilizer as the main fertilizer, in order to increase the vitality of the leaves and enhance the plant's resistance to diseases.
