However, if not properly maintained, it is easy to cause Phnom Penh Cymbidium leaves yellowing or falling appearance! So how can we solve this problem if it really occurs?

What if the leaves of Phnom Penh turn yellow and black?

1. Fertilization

When the amount of fertilizer exceeds the range that plants can bear, it may cause damage to the roots of flowers, which is shown on the potted soil, that is, the leaves of flowers appear yellow leaves and lose their luster.

Solution: should immediately stop fertilizing, a lot of watering. If it is serious, it is recommended to replace all the soil directly, including the soil at the root, but not to damage the root system.

2. Nutrition

The above is that excessive fertilization will lead to yellow leaves, the same amount of fertilizer is too small, fertilizer is uneven, nutrition supply is not available, or the loss of nutrients is too severe, plants do not get any nutrients, will also make the leaves yellow.

Solution: fertilization combined with watering, the soil can use more fertile sandy soil, appropriate amount of alum fertilizer water.

3. Sunshine

If a plant is allowed to grow in a dark environment for a long time, its leaves will slowly turn yellow.

Solution: if you can't change the position of the plant, move the plant to the sun for at least a few hours a day, but pay attention to shading to prevent direct sunlight, sooner or later is the most appropriate, or move directly to a brighter place for display.

4. Air permeability and water permeability

If the root system grows in stagnant water or too moist soil for a long time, it will make the plant unable to breathe and cause its leaves to turn yellow.

Solution: when watering, we should pay attention to the situation of water seepage to ensure that the soil layer in the basin can be evenly watered.

The solution to the loss of leaves in Phnom Penh

1. Rotten root

Take out the plant and check the rotten root. If the root is slightly rotten, cut off the injured root and leave the healthy one. Move gently to avoid damaging the entire root system. Change the soil and plant again, using drained and breathable containers and soft sandy soil. Usually, the water supply should not be too much, and the frequency and water should be reduced. Once a week in summer and even less in winter, replenish water once a month for ten and a half days. If dust is found on the leaves, you can spray water. When formally supplying water, pour it thoroughly and see that there is a slight leakage from the bottom of the basin.

2. Air drying

Provide a moist environment for the leaves and maintain a certain amount of moisture. Especially when autumn and winter are relatively dry, pay attention to spraying water, the water temperature is about the same as room temperature, and you can spray the leaves with water every week.

What is the best fertilizer for Phnom Penh hanging orchids?

If we want to fertilize it, we can choose some fertile natural fertilizer, such as fermented cake manure, human manure or human urine, cow, sheep and pig manure, chicken and pigeon manure. If you don't want to use these fertilizers, you can also choose to use the dregs of sesame sauce. These fertilizers are mixed with the right amount of water to form a dilute liquid when used, which has the best effect. At the same time, you must be careful not to be too thick and prefer to be dilute.

How to split Phnom Penh Cymbidium

First, raise well

A big factor to ensure that it can be divided into two pots is that the original basin must be raised very well, because if it is not properly raised, it is very likely that the number of it is not large, and it is more likely that it will not be able to live because it is weak. So first of all, we have to make sure that the ramets are very luxuriant.

2. Take out

1. First of all, we have to get the original flowers out of the flowerpot. Generally, the way we take is to buckle upside down so that it won't hurt the root. At this time, we will notice that the flowers have a lot of stems linked together. So we need to get some soil out, those smaller roots are also removed, and then we begin to formally split.

2. In order to look good, we need to put three or four plants together, and then we can put them into the pot. The soil can be ordinary, and it is a good way to put some peanuts or walnut skins underneath, because in this way its water permeability will be improved.

Third, reinstall

Then we have to reinstall it, normally we have to apply a little bit of water to it, so that its soil will not dry, and it will not be too wet to cause root problems. And we can't let the remade plant face the sun and wait until it grows well before it can be placed at will. This is a very good plant, if it grows to a certain period of time, you can try to divide it.

As mentioned above, in fact, Phnom Penh is a very good cultivation of foliage plants, even if there are some problems, do not worry, find out the reasons, the right medicine, the problem will be easily solved! Friends who like can raise one or two plants at home!
