What if the leaves and tips of Phnom Penh are yellow?

The leaves of Phnom Penh Cymbidium are wide linear and light green, the edges of the leaves are golden, and the leaves are slender and soft, so they are good foliage plants. However, if the leaves of Phnom Penh turn yellow, it will greatly reduce its ornamental. What about the yellow leaves of Phnom Penh? What should I do with it?

Not everyone is a master of gardening, so it is hard to avoid thorny things when raising plants, and they are caught by surprise when their beloved plants get sick. It doesn't matter. Today, the editor will tell you why the leaves of Cymbidium are yellowing and how to deal with them:

The main results are as follows: 1. The air permeability and water permeability of the basin soil are not good, which leads to the accumulation of water in the basin soil for a long time, and the difficulty of root respiration, so the leaves turn yellow naturally. At this time, we should loosen the soil and control moisture in time.

2. Phnom Penh Cymbidium belongs to semi-shade flowers, but it also needs light; at least 4-5 hours of light should be guaranteed every day. Otherwise, the leaves will turn yellow when the chlorophyll decreases. The best way is to put it under an indoor incandescent lamp or on a balcony.

3. Without watering for a long time, the roots of Phnom Penh Cymbidium lost water, and the lower old leaves turned yellow. It should be watered thoroughly to keep the basin soil warm and moist.

4. Excessive fertilization exceeds the demand of Phnom Penh; the leaves will appear bright and uneven after fertilization, and then the roots will appear yellow due to malnutrition after partial decay. So at this time should stop fertilizing, more watering, or turn the basin to wash the roots, change the new soil is also a very good way.

5. Without turning the basin and changing the soil for a long time, the soil is hardened; when all the nutrients in the basin are exhausted. The deficiency of the three most important elements, nitrogen, phosphorus and potassium, makes the leaves gradually turn yellow. At this time, the soil should be changed or fertile loam and fertile water should be replaced in time.

Maintenance recommendations:

1. Phnom Penh hanging orchids prefer a semi-overcast environment. If the sun is direct and the air is dry, it is most likely to cause leaf tip scorch. Therefore, the hanging orchid must be placed in a cool and ventilated place, especially to pay attention to often spraying water to the leaf surface to increase environmental humidity.

2. Phnom Penh orchids like to be wet, but if too much watering or poor drainage of basin soil will lead to withered leaves and bananas due to rotten roots. Improper watering and fertilization will also cause the leaves to dry up.

3. Phnom Penh hanging orchids like fertilizer. If there is not enough fertilizer and water, the color of the leaves will become lighter and the leaf tips will be scorched. But do not apply too much fertilizer.

4. We must pay attention to frost injury in winter. Freezing damage occurs when the ambient temperature is below 4 degrees Celsius.

Phnom Penh has strong adaptability, drought resistance and cold resistance, and has strict requirements on the soil. It generally grows better in well-drained, loose and fertile sandy soil. Light requirements are not strict, generally suitable for growth in medium light conditions, but also resistant to weak light. Wrong management will make the leaves of Cymbidium turn yellow and even wither. Therefore, we usually enjoy the benefits it brings to us, but also need careful care, do a good job of daily maintenance.
