What is the yellowing of orchid leaves?

Throughout the ages, I do not know how many writers have written praises for the four famous flowers of Meilan, bamboo and chrysanthemum, and some people who are indifferent to fame and wealth boast of flowers and exercise self-discipline. Among the four famous flowers, only the orchid is the most elegant. Complemented by green leaves, the orchid looks more beautiful and smart. In the past, the ancients praised its "not to be unmanned but not fragrant, not to be trivial because of the cold", and now people praised it as "elegant but not vulgar, beautiful but not demon". This is also the reason why orchids are loved by many people.

But in the planting, other people's orchid green leaves, their own orchid leaves are gradually yellow, and even rotten, many people are very puzzled. Next, let the editor introduce the causes and solutions of the yellowing of orchid leaves.

1. Excessive fertilization

Many people know that too much fertilization will lead to seedling burning. Orchids are no exception, too much fertilizer is oxidized and decomposed by microorganisms in the soil, which will release a lot of heat, do great damage to the roots of orchids, and even lead to root rot and yellowing leaves.

Solution:

Fertilization should not be too rigid, the prescribed amount of fertilizer is only a reference, but the growth of each flower is different, according to the changes in the growth of flowers after fertilization, the amount of fertilizer should not be too much.

2. Malnutrition

Orchids need a lot of nitrogen supplement in the process of growth and development. if the nitrogen content in fertilizer is low, the orchids lack the raw materials necessary to synthesize chlorophyll, the leaves will turn yellow gradually, and the growth of orchids will become worse, and finally the plants will be short and beautiful.

Solution: when choosing fertilizers, we should know in advance the organic elements needed by orchids and reasonably match different kinds of organic fertilizers so as to avoid the yellowing of leaves due to malnutrition in the process of orchid growth.

3. Excessive application of water

In the process of planting orchids, if too much water is applied and not discharged in time, it will lead to root rot, unable to absorb nutrients, and eventually lead to yellowing of leaves.

Solution: reasonable watering, not too much, so as to avoid rotting roots. It should not be too little, otherwise the soil will dry and affect the absorption of water-soluble minerals.

After the introduction of the editor, do you know more about orchid planting? Orchids have higher requirements for culture conditions, so do not rigidly follow the prescribed planting methods, adjust at any time according to their own orchid growth in order to reproduce the beauty of green leaves.
