What to do if the leaves of an orchid wither?

The normal life span of orchids is 4-6 years, the leaves of orchids are green, oily and bright, and vibrant, but due to our daily planting and improper management, some orchids die out in 2-3 years, which is manifested as rapid yellowing of leaves, and then withering, which is the weeding of orchids.

1. Symptoms of orchid weeding.

Orchid weeding is manifested as the orchid leaves start from the tip of the leaf or the edge of the leaf, and the whole leaf quickly yellows downward, the yellowed leaf is the old grass of the whole orchid, and the order of leaf yellowing is from the outermost leaf to the yellow, and then to the inner center leaf, one by one, the yellow is finished, the next one, and the central leaf finally yellows. The whole yellowing speed is very fast, a single leaf in about 3 days from head to toe all yellowing, and the diseased leaves are different, the yellowing color of the leaves of the weeding is evenly transitioned, no color jumping, first yellow and then withering, but also from the first yellowing place to start withering, **yellow early, **also withered early, easy to identify.

2. There are two types of weeding.

Orchid weeding is divided into two types: normal weeding and abnormal weeding, normal weeding is that the orchid has reached its growth life, self-extinction, and completed the life cycle, at this time, the old seedlings that have reached their life span will quickly yellowish and wither, which belongs to the normal physiological phenomenon of natural growth of orchids. Abnormal weeding is the occurrence of disease, and the yellowing and wilting of leaves that occur without normal metabolism.

3. Three scenarios of abnormal weeding.

1. Put on the basin. Orchids that have just been potted will have a potting period, in this potting period, the orchid is mainly suitable for the new environment, and then grow new roots, so that the orchid enters the normal growth stage, many times we pot the orchid, the orchid can not adapt well to the new environment, which will cause the orchid root system to be unable to grow, and can not get along with the small environment in the pot, which will cause the nutrients consumed by the orchid plant to not be effectively supplemented by the root system. At this time, the old seedlings of orchids will reduce the consumption of nutrients or preserve nutrients by retiring weeds to ensure the growth of new seedlings.

2. Flowering. The consumption of orchid flowering on the impact is very large, sometimes the root system can not replenish the nutrients consumed by flowering in time, and during flowering, the orchid plant also gives priority to the consumption of nutrients for flowering, at this time the old seedlings are in a state of hunger, and the flowers will extract the nutrients of the old seedlings for consumption, which will lead to the yellowing of the leaves of the old seedlings and the appearance of weeding.

3. Bad roots. When the soil for planting orchids is compacted, watering is easy to compact, which will lead to hypoxic rot of the orchid root system, and the root system will be manifested on the leaves if there is a problem. The excessive fertilizer content contained in the planting material will also lead to problems in the root system, resulting in the excessive weight of the planting material There are two situations, one is that the base fertilizer of the planting material is added too much, and the other is that the concentration of fertilizer in the later stage is too large, and the fertilizer is too heavy and easy to burn the root of the orchid, so that the weeding situation occurs.

First of all, you should water in time, not only spray the leaves with a watering can, but also water the soil thoroughly until the bottom of the pot flows water; Then you have to apply some fertilizer, sprinkle it in the soil, and loosen the soil, bask in the sun for a while and put it in a cool place, and it will soon be able to regain its vitality.

Fertilize. Orchid is a plant that needs the same thing, and it grows well after fertilization.

At this time, we will cut off the withered leaves, and then we will try some fertilizer, and then water the orchid properly, so that the orchid leaves can grow again.

Causes: 1. Overwatering. Although orchids prefer a humid environment, they should not be watered too much, resulting in rotten roots and dead leaves.

2. Less fertilizer or excessive fertilization. Less fertilizer will cause orchids to be malnourished and withered leaves, and excessive fertilization will cause seedlings to burn and withered leaves.

3. Excessive lighting. Orchids are shade-loving and yang-phobing flowers.

4. The humidity is too low. The humidity requirement of the orchid macro calendar is kept between 60-80%, and if it is too dry, it will cause dead leaves.

5. Low temperature. Orchids are suitable for survival in warm environments, and low temperatures or freezing can cause the orchid to wither.

6. Suffering from diseases or encountering pests. These can cause the orchid to wither leaves.

7. Change the pot and soil in time. Generally, orchids need to be repotted and changed once in about 2 to 3 years.

8. Air pollution occurs in the environment where orchids are cultivated. Orchid is one of the indicator flowers of air pollution, orange judgment, very sensitive to air pollution, such as soot, soot, smoke, paint, air fresheners, chemical synthesis preparations, sandworms, etc., a little carelessness will lead to orchid dead leaves and even death.
