What about yellow leaves?

One leaf orchid is also known as big leaf evergreen, bamboo leaf plate, Kowloon plate, bamboo tendon and so on. It is a perennial evergreen persistent herb of the family Liliaceae. It is native to various provinces and regions in southern China and is now cultivated in all parts of China. It is widely used and has a very high ornamental value. Let's take a look at what to do if the leaves turn yellow.

The light is too strong

[reason] one-leaf orchid bogey is in direct sunlight, and short-term sunlight exposure may also cause leaf burns and yellowing, reducing ornamental value.

[methods] one-leaf orchid can be cultivated in bright indoor all the year round, but it can not be placed in direct sunlight either indoors or outdoors.

Too little light

[reason] one-leaf orchid is extremely shady and can be watched for months even in a dark room, but too dark for a long time is not conducive to the germination and growth of new leaves. If the light is too little in a dark place for a long time, the leaves will turn yellow.

[methods] if it is placed in a dark room, it is best to move it to a place with bright light for a period of time to facilitate growth and viewing, especially during the period from the germination of new leaves to the growth and maturity of new leaves.

Too much watering

[reason] overwatering is also one of the reasons for the yellowing of the leaves of Cymbidium, which likes water and has a certain tolerance, even if it is dry for several days, it will not die, but if too much watering will affect the respiration of the roots and cause the leaves to yellowing.

[methods] the watering of Cymbidium should be dry and wet, not too much, but not too little, and sufficient water is needed during the growth period.

Fertilization is too thick

[reason] Cymbidium does not have a great demand for fertilizer, so it is best to apply light fertilizer each time. If too much fertilizer is applied, it will burn roots and destroy the growth of Cymbidium, and the leaves will turn yellow due to fertilizer damage.

[methods] dilute liquid fertilizer can be applied 1-2 times a month to promote the germination and robust growth of new leaves, to ensure that the leaves are beautiful and bright, and not to apply too much fertilizer.

Pest infection

[reason] Red spiders are very easy to appear in orchids maintained indoors, and insect pests are also the reason for the yellowing of leaves.

[methods] the two sides of leaves should be checked frequently, and triclofenac and nisolan should be sprayed in time.
