What if the leaves of family potted orchids turn yellow?

Hanging orchids should pay attention to sunscreen, dryness, waterlogging and cold protection in normal maintenance. Hanging orchid likes semi-shade, and the indoor light is suitable near the south window and the north window, but from June to August in summer, it is necessary to avoid the hot sun at noon, otherwise the leaves will be dry and scorched due to excessive light and dry air. But the light should not be too dark, otherwise the growth is thin, the leaf color is light, and the gold heart and Phnom Penh are not significant. In a semi-overcast environment, it is best to have a few hours of light every day, and it is more beneficial to growth if you put it in a sunny place in winter.

But the pointless leaves of Cymbidium cultivated in the family turned yellow, so why did the leaves turn yellow? What should I do if it turns yellow? Let's deal with this problem now.

The causes and treatment methods of yellowing of Cymbidium leaves:

1. Improper fertilization: excessive fertilization causes yellowing of leaves, which exceeds the needs of the plant. At first, the leaves are bright and uneven, and then the roots rot, and the leaves are yellow.

Treatment method: should stop fertilizing, irrigate more water, or turn the pot to clean the root and replace the new soil.

2. Nutrient loss: all kinds of nutrient elements in the basin soil have been exhausted, the three elements of nitrogen, phosphorus and potassium have not been replenished in time, the plant is lack of nutrients, and the leaves are yellow and thin.

Treatment method: fertile loam and fertile water should be replaced in time.

3, lack of sunlight: although the orchid is a semi-negative flower, it should see more than four hours of astigmatism at least every day, otherwise the chlorophyll will decrease and the leaves will turn yellow.

Treatment: should set aside free time every day to put the orchid in the sun for a few hours, but not too much exposure to the sun.

4. poor air permeability and water permeability of basin soil: stagnant water in basin soil does not dry for a long time, root respiration is difficult, which leads to leaf yellowing.

Treatment method: loosen the soil and control moisture in time. Fifth, it is impervious to water for a long time. The roots of Cymbidium lose water, and the lower old leaves turn yellow. It should be watered thoroughly to keep the basin soil warm and moist.

In short, the cultivation of hanging orchid, we should grasp the hanging orchid like shade, often spray water, often fertilize, often change the basin of the four major maintenance points, I believe that breeding a beautiful hanging orchid is not a problem. In this way, we can try our best to avoid the yellowing of the leaves of the orchid. I believe that even if you encounter the yellow tip of the leaves of the beloved orchid, you will know what to do!
