What to do if the leaves of the tree turn black?

1. Cut off the black leaves

When these black leaves appear in spring, the situation can be alleviated. The leaves will recover after a period of time, and the new leaves that grow will turn green. If there are a lot of black spots, it will be difficult to recover and the leaves need to be cut off directly, which will not affect the appearance.

2. Change the maintenance method

In addition to cutting off the black leaves, you need to find out the root cause and then make adjustments and changes to find the right remedy.

1. Appropriate light: It is a plant that likes semi-shade and is afraid of exposure to the scorching sun. If there is direct sunlight, the plant will show signs of burns and the leaves will turn black and burnt. Sunlight needs to be provided correctly, maintaining about 60% scattered light, so that the growth needs can be met.

2. Keep warm in winter: The smooth sailing plant likes hot weather and is afraid of cold climate. The suitable temperature is between 20-25 degrees Celsius. Pay attention to keep warm in winter. The temperature needs to be raised to above 10 degrees Celsius, otherwise the plant will be burned and blackened.

3. Water and fertilizer factors: Improper application of water and fertilizer is also one of the reasons, and the impact is great. You can increase or decrease it.
