The solution to the yellow and black leaves of pittosporum

Paulownia flower is a kind of potted plant, because its flowers are relatively large and the color is pink, so many flower lovers raise paulownia at home and put it in the living room or balcony and other places, we may encounter some problems in the process of breeding, such as the phenomenon that the leaves suddenly turn black and yellowing, so the editor of this chapter is dedicated to explain this problem for you. Let's take a look at it with Shuai Shuai.

1. What to do if the tree turns black and yellow

1. Proper watering

Paulownia is a kind of drought-tolerant plant, so it is not necessary to hold water every day, pay attention to watering as little as possible, do not dry, do not water, and to correct a view, this is also an obsessive-compulsive disorder of many people, do not see the soil white, dry, in fact, it is not, if you take away the surface layer, you will find that it is wet inside. In addition, paulownia will enter the dormant period when the temperature is low to a certain degree in winter, once it enters the dormant period, it can be irrigated once every two months, and do not water the leaves directly, because the villi on its leaves will produce water stains when they touch water, causing the leaves to rot.

2. Absorb enough scattered light

For this kind of potted flower plant, we should not give it direct strong light, and it is best placed in a place with scattered light, of course, when it is in the mature flowering stage, if it is in the seedling stage, it should be allowed to receive sufficient sunlight, part of direct light and scattered light in winter.

3. Clean the leaves after fertilization.

Many of us have this habit and don't care after applying fertilizer. In fact, this is very wrong. If the fertilizer that is not fully absorbed remains on the leaves, it will cause the leaves to rot. So we must clean the leaves with clean water after applying fertilizer.

2. What to do if the leaves of the tree fall off?

The loss of leaves is generally related to watering, other factors will not cause its leaves to fall, we should be careful not to water the leaves directly when watering, which will damage the leaves, which will cause the leaves to fall for a long time. Watering should also maintain the humidity of the air, it is best to use spray watering, will also be around the basin to spray water.

The above is the solution to the yellowing and blackening of the leaves of paulownia. Because the drought tolerance of paulownia is relatively good, we must pay attention to watering, and fertilizers will react with the air, so the leaves will rot, resulting in blackening, yellowing, and even shedding.
