The leaves of the purple orchid have turned yellow, what should I do? What is the reason? Please let

Flowers appear yellow leaves, depending on the characteristics of their occurrence, there are the following situations:

One is water yellow. Caused by over-frequent watering, it is characterized by no obvious change in old leaves and yellowing of young leaves; This should be done with immediate water control;

The second is dry yellow. Caused by lack of water and drought, it is characterized by the first yellow leaves from the bottom up, if the lack of water for a long time, the whole plant will be yellow, and even die, should be watered in time;

The third is fat yellow. Caused by excessive fertilization or high concentration; It is characterized by thick, shiny, and uneven young leaves; Fertilizer, cultivation and watering should be controlled;

Fourth, hungry yellow. It is caused by insufficient fertilizer, low fertilizer concentration, and long fertilization interval; It is characterized by the first yellow of young leaves and young stems, and if you do not fertilize in time after seeing this phenomenon, it will also cause the whole plant yellow leaves or even die; For flowers lacking fertilizer, avoid applying a large amount of thick fertilizer at one time, so as not to cause root burning;

Fifth, iron deficiency yellow leaves. Due to the great change of soil fertility conditions, the phenomenon of yellow leaves often occurs in greenhouses, which is characterized by obvious young leaves, light old leaves, yellow mesophyll, green leaf veins, and the formation of a typical network. It can be solved by applying ferrous sulfate aqueous solution, and the method is: 7 parts of cake fertilizer, 5 parts of ferrous sulfate, and 200 parts of water are prepared into multiple liquid water.

Haha I have also planted orchids before, its habit is cool and dry, it is best not to use mud to plant, go to the mountains to get some gravel to plant, don't water too much, don't sun for too long 3 hours a day is the best.

1. Dry yellow. Solution: Pay attention to watering enough and water thoroughly.

2. Lack of fat yellow.

Solution: Wax should always check the potting soil, if there is a dry phenomenon, the soil should be replaced, usually thin fertilizer is applied diligently, and some alum water should be poured in a timely manner to supplement iron.

3. Lack of light yellow:

Solution: Timely supplemental light can avoid this round of stuffiness.

4. Fertilizer yellow: Solution: Fertilizer should be stopped immediately, and part of the fertilizer should be washed with a large amount of cleaning.

5. Burning yellow: Solution: When the sun is too strong in summer, move the plants to semi-shade or shade.

6. Water yellow: Solution: Put the flowers off the pot.

Reason: Violet is suitable for growing in a cool environment, but it should not be too dark during the breeding period, and its leaves will turn from green to yellow if it is not exposed to light for a long time.

Solution: Move to a sunny place in time, so that it can fully receive light, it is best to raise it in the sun for 6 hours a day, and its leaves will turn back to green only when the sun is sufficient.

Reason: Watering is the most important part of breeding, if the amount of watering is too large, the leaves will turn yellow due to poor root breathing, and if it is serious, it will lead to the death of the whole plant.

Solution: At this time, you must water less, control the amount of watering, and then move the potted plants to a place with good air circulation. Only by allowing the water in the potting soil to evaporate as soon as possible will the plant slowly return to its original state.

Reason: Violets need nutrients during the growth stage, but if they are not fertilized for a long time, the leaves of the plant will turn yellow due to lack of nutrients.

Solution: Apply some fertilizer to the plant as soon as possible, but not too much fertilizer at once, and keep increasing. When fertilizing, thin fertilizer should be applied frequently, so as to ensure that the leaves will gradually recover when the nutrients are sufficient.

Summary. Good afternoon, dear.

There is no way to remedy the yellowing and blackening. However, there are several reasons for this.

Situation 1: Too much watering. This is a situation with a high probability of occurring, because watering is not measured, and it is believed that the more watered, the better the orchid will grow, resulting in waterlogging in the roots, and then yellowing the leaves.

Situation 2: Too much fertilization. Too much fertilization is commonly known as "burning" seedlings, which is extremely unfavorable to the growth of orchids and can easily lead to the death of orchids, so the more fertilization, the better.

Situation 3: Pests and diseases. In this case, it is necessary to carefully observe the yellowed leaves to see if there are insects eating or ulcerating, if there is, it means that there is a pest and disease, and it is necessary to prescribe the right medicine.

Situation 4: The orchid itself is yellow. Some orchid leaves are yellow in their own right, and they are also very ornamental, so don't bother to study how to make them green.

Situation 5: The light is too strong. Plants with large leaves, such as orchids, are very afraid of strong light, which can damage the leaf tissue cells, and the leaves will turn yellow and black, so it is best to put them in a place with low light.

Situation 6: Lack of nutrition. Nitrogen fertilizer has a good effect on supplementing the chlorophyll of the leaves, and if the orchid lacks nitrogen fertilizer, it will also cause the leaves to turn yellow, at this time.

Excessive fertilization. Too much fertilization is commonly known as "burning" seedlings, which is extremely unfavorable to the growth of orchids and can easily lead to the death of orchids, so the more fertilization, the better. Scenario three:

Pest. In this case, it is necessary to carefully observe the leaves of the yellowed part, whether there are insects cannibalizing or ulcerating the eggplant, if there is, it means that there is a pest and disease, and it is necessary to prescribe the right medicine to tremble and widen the traces.
