The growth habit of Cymbidium how to solve the problem of yellowing of Cymbidium leaves

The hanging orchid is the plant that many families like, many people choose to breed the hanging orchid, but some people breed the hanging basket to appear the leaf turns yellow phenomenon, how should this do? Let's take a look at the growth habits of Cymbidium and how to solve the yellowing of its leaves.

The growth habits of Cymbidium:

If you want to know why the leaves of Cymbidium are yellow, you must first understand the growth habits of Cymbidium. Cymbidium likes warm, moist and semi-overcast environment. It is adaptable, drought-resistant, but not cold-resistant, demanding on the soil, and grows better in well-drained, loose and fertile sandy soil. The requirement of light is not strict, so it is suitable to grow under medium light conditions and can withstand weak light. The suitable temperature for growth is 1525 degrees Celsius and the overwintering temperature is 0 degrees Celsius.

What if the leaves of the orchid turn yellow?

Reason 1, improper fertilization: excessive fertilization caused leaves yellowing, fertilization exceeded the needs of the plant, the beginning of the leaves were uneven, after the root system rotted, the leaves were yellow.

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

Reason 2, nutrition loss: the various 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.

Solution: fertile loam and fertile water should be replaced in time.

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

Solution: you 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.

Reason 4, poor air permeability and water permeability of basin soil: long-term stagnant water in basin soil, difficulty in root respiration, resulting in yellowing of leaves.

Solution: loosen the soil and control moisture in time. If it is not watered for a long time, the root of the orchid loses water and the lower old leaves turn yellow. It should be watered thoroughly to keep the basin soil warm and moist.
