This flower should be placed in a semi-shaded area; whether kept at home or in the workplace, it is very good for our mood. Many friends say that after growing this flower for a long time, for some unknown reason, its leaves have actually turned black. What exactly is going on, and how should it be handled?

I. Causes

1. Not adapting to the environment

If this flower of yours was newly bought, it has gone through long-distance transport and has not yet adjusted, so the phenomenon of blackening leaves will appear. Moreover, it is a tropical green plant that needs high temperature and high humidity, and most regions of our country can hardly meet these conditions all year round, so blackening leaves are very hard to avoid.

2. The plant has already aged

It only blooms once in its lifetime. Some friends' plants have already bloomed, and after the flowering period, it will slowly age and its leaves will also turn black. If that is the case, you can choose to throw it away, or wait until its offsets grow out and then divide them.

3. Improper watering

If watering is done poorly, its leaves will also turn black. Generally, when watering it, you only need to sprinkle water into the center of the leaves; if the air is too dry, you should also sprinkle water around it. But there must not be a lot of standing water in the pot, otherwise it will cause the leaves to turn black and even root rot.

II. Solutions

If the weather is stuffy and hot, or the temperature is relatively low, its leaves will also become withered and black, so the soil should be kept in a moist state, and you can sprinkle water on the leaves once or twice a day. The water must be clean, and you can also sprinkle very diluted fertilizer water. If it has already finished blooming and begun to age, you can only throw it away; it is very difficult to help it recover.

III. Care Tips

Generally, as long as you place it in an area with wind and light and give it the water it needs, it can grow very well. We need to remember these points and take good care of it:

1. If there is no ventilation and the temperature and humidity are very high, it is prone to attack by pests and diseases. If it is a disease, you can spray carbendazim; if it is an insect, you can sprinkle omethoate. You can also buy specialized treatment medicine on the market and bury it in the pot, which will be more effective. It should be placed outside for treatment, otherwise the chemicals will pollute the air in the home.

2. If you want to water it, do so before noon. In summer, water is needed morning and evening; pour the water into the leaf cup, and at night clean the leaves and sprinkle water around the air to increase humidity.
