1、 Pruning

Because plants with Phnom Penh are actually cultivated, its growth environment is more harsh than the original. In fact, we should cut off the leaves without Phnom Penh, otherwise this kind of leaves will take away its nutrients, and the leaves with edges will be less and less, and finally the whole leaves will become the same. So once we find that its leaf Phnom Penh is slowly disappearing, we have to cut it off so that it can not affect other leaves

2、 Illumination

In fact, its Phnom Penh disappeared largely because its light is not strong, and this may be the biggest reason for the disappearance of most plants Phnom Penh. We should know that although it is not a plant that likes sunshine, it still needs sunshine. We need to put it outdoors for two hours every day. Of course, it's better to put it out in the morning and evening. This will be more obvious in Phnom Penh. So if it's because we can't see light in the place where we let the plant stay, we should keep it in a place with good light for a period of time

3、 Fertilization

Fertilizer is also the reason affecting it, because we give it less phosphorus fertilizer and more nitrogen fertilizer, which will lead to more chlorophyll, so Phnom Penh will disappear. If this is the reason, we need to apply a certain amount of phosphorus and potassium fertilizer to it, but we should know that Phnom Penh disappears very little for this reason

4、 Watering

Watering is also one of the influencing factors. We need to pour a small amount of water on it, but spray more water
