The yellow leaves of spider orchid are watered

Improper watering

The hanging orchid likes the wet environment, the basin soil can not be too dry, but this does not mean to water the hanging orchid all the time! Watering the orchid is also limited, too much watering, coupled with the basin soil drainage is not smooth to cause stagnant water, the root system of the orchid can not breathe, reflected on the leaves is the leaves yellowing!

Another reason is that the hanging orchid is watertight for a long time, resulting in the loss of water at the root of the hanging orchid, and the lower old leaves will turn yellow.

Solution.

Water too much to timely loosen the soil and control moisture, and usually watering must be thoroughly. ~

Hanging orchids are not suitable for watering every day, so flower friends can be "lazy"! In general, hanging orchid watering about ten days in winter watering, summer depending on the dry condition of 3-5 days watering, to water thoroughly, and smooth drainage.

If the air is dry, you can often spray and wash the branches and leaves with a sprayer, which can not only increase the air humidity, but also prevent the dry tip of the leaves, but also keep the leaves clean, improve the ornamental, and get more with one stone.

In addition, watering time flower friends should pay attention to, it is best to water in the morning or evening, can not be watered at noon, a hot day suddenly to the hanging orchid basin cold water, will be cold, catch a cold. Also, during the growing period, you can appropriately increase the amount of water, but not too much.

What if the leaves of the orchid turn yellow? Analysis on the causes of yellowing of Cymbidium leaves

Hanging orchid has a strong function of absorbing harmful gases, if it is a new house decoration, must put more pots of hanging orchid at home, in order to purify indoor air and absorb formaldehyde emitted by furniture. However, if it is not properly maintained, it is easy to raise the orchid to death.

What to do if the leaves of Cymbidium are yellowed? 1. The leaves of Cymbidium are yellowing: too much fertilizer

Fertilizing too much exceeds the needs of the plant. At the beginning, the leaves were shiny and uneven, the roots rotted and the leaves were yellow. Should stop fertilizing, irrigate more water, or turn the pot to clean the root and replace the new soil.

Solution.

Stop fertilizing immediately, irrigate clean water, or turn over the basin to change soil. Cymbidium usually does not have a great demand for flower fertilizer, if you want to grow vigorously, you can use bean dregs to soak in water and dilute it after full fermentation. Can also use a little compound fertilizer, preferably organic fertilizer, nitrogen, phosphorus and potassium compound fertilizer is the best, once every half a month. When the temperature is below 4 degrees Celsius, the orchid should stop fertilizing.

2. The leaves of Cymbidium are yellow: the pots have not been changed for a long time.

Without changing the soil for a long time, the various nutrient elements contained 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. In order to have luxuriant stems and leaves, the soil and basin should be changed in March every year. If the basin is deeper and the base fertilizer is more sufficient, the basin can be changed once every two years. When turning the basin, knock the plant out of the basin, cut off the withered roots and excess roots, replace it with a new humus-rich culture soil, and then apply livestock hoof horns or rotten cake fertilizer as base fertilizer. After planting, put the seedlings in a warm and semi-overcast place.

3. The leaves of Cymbidium are yellow: the light is not enough.

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. The lower withered leaves and yellow leaves should be picked at any time, and the yellow head should be cut off obliquely with scissors when the leaf tip is yellow.

Solution.

We need to let the orchid be exposed to astigmatism for at least four hours a day, or we can put the orchid under the indoor incandescent lamp or on the balcony. When the sun is very strong in summer, put the orchid in the shade and do not expose yourself to the sun.

4. The leaves of Cymbidium are yellowing: the soil is impervious.

The permeability and water permeability of basin soil are poor. The long-term accumulation of water in the basin soil makes it difficult for the root system to breathe, which leads to the yellowing of the leaves and the front end of the leaves. It is necessary to loosen the soil and control moisture in time and place a well-ventilated environment. Usually to maintain normal humidity, should not be dry, should not be too wet.

5. The leaves of Cymbidium are yellow: they are not watered for a long time.

Long-term watering is impervious. The roots of Cymbidium lose water, and the lower old leaves turn yellow. It should be watered thoroughly to keep the basin soil warm and moist. Summer watering should be adequate, around noon and evening should also spray water on the branches and leaves, timely cleaning the dust on the leaves to prevent the leaves from drying up. Under 5 ℃ in winter, less watering, basin soil should not be too wet, otherwise the leaves will be easy to yellowing.

Solution.

Water too much to timely loosen the soil and control moisture, and usually watering must be thoroughly. Hanging orchids are not suitable for watering every day, so flower friends can be "lazy"! In general, the orchid is watered once every ten days in winter and every five days depending on the dry condition in summer. It should be thoroughly watered and drained smoothly.

If the air is dry, you can often spray and wash the branches and leaves with a sprayer, which can not only increase the air humidity, but also prevent the dry tip of the leaves, but also keep the leaves clean, improve the ornamental, and get more with one stroke. In addition, when watering, flower friends should pay attention to it. It is best to water it in the morning or evening, not at noon, and suddenly water the orchid pot with cold water on a hot day, which will cool your heart.

6. The leaves of Cymbidium are yellowing: insufficient nutrition

All the nutrients needed by the orchid come from the soil in which it takes root, so if the potted soil is not replaced for a long time, some elements that we are easy to ignore will gradually disappear, and the orchid will lack the nutrients needed for growth. the leaves will turn yellow in appearance!

Solution.

Of course, the best way to solve this problem is to change the basin for the orchid. Remember to mix in the appropriate base fertilizer when changing the basin. After planting, put the seedlings in a warm and semi-overcast place.

7. The leaves of Cymbidium are yellowing: the temperature is uncomfortable.

The suitable temperature for the growth of Cymbidium is 15-25 ℃, the fastest growth is when the temperature is 20-24 ℃, the growth stops above 30 ℃, and the overwintering temperature is 5 ℃. If the temperature is too low, it will also be reflected on the leaves of the orchid. So, flower friends in the north must remember that the orchid moves indoors in winter.

Solution.

The best solution, of course, is to give the orchid the right temperature ~ the most suitable growth temperature is 20-24 ℃. Usually I think it's good to keep this temperature.

What about the yellowing of orchid leaves? can you cut the yellowing leaves?

Hanging orchid, also known as hanging potted grass, laurel orchid, hook orchid, folding crane orchid, is one of the common varieties of household potted plants, how to do when the leaves turn yellow in the process of breeding? Can I cut the yellow leaves of the orchid? Let's take a look at the answer.

Can you cut the yellow leaves of the orchid?

You can use scissors to cut half of the yellowing leaves of the orchid, or even cut off all the leaves.

The leaves of Cymbidium are dry, indicating that the leaves are old, even sick, and can no longer carry out normal photosynthesis, so on the whole, the contribution to the plant is not great, so the dried leaves can be cut off half or all, on the one hand, it is beautiful on the whole, on the other hand, it is beneficial to the growth of the plant.

The reason for the yellowing of Cymbidium leaves:

1. Fertilizing too much, exceeding the demand of the plant, the leaves will appear bright and uneven after fertilization, and then the roots will turn yellow due to malnutrition after partial decay. So at this time should stop fertilizing, more watering, or rice basin to wash the roots, change the new soil is also a very good way. It can be seen that the spatial soil liquid concentration is very important.

two。 The soil has not been turned over for a long time, and the soil is hardened when all the nutrients in the basin are exhausted. The deficiency of the three most important elements, nitrogen, phosphorus and potassium, makes the leaves gradually turn yellow. At this time, the soil should be changed or fertile loam and fertile water should be replaced in time.

3. Cymbidium is a semi-shade flower, but it also needs light, so you should keep at least 4-5 hours of light every day. Otherwise, the leaves will turn yellow when the chlorophyll decreases. The best way is to put it under an indoor incandescent lamp or on a balcony.

The solution to the yellowing of Cymbidium leaves:

1. The yellowing of Cymbidium leaves may be due to excessive fertilization, which exceeds the requirement of the plant. At the beginning, the leaves were shiny and uneven, the roots rotted and the leaves were yellow. Should stop fertilizing, irrigate more water, or turn the pot to clean the root and replace the new soil.

two。 The yellowing of orchid leaves may also be caused by not turning the basin and changing the soil for a long time. 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. Fertile loam and fertile water should be replaced in time.

3. The yellowing of orchid leaves may also be caused by lack of light. 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.

4. The air permeability and water permeability of basin soil are not good, which leads to long-term stagnant water and difficulty in root respiration, so the leaves turn yellow naturally. At this time, we should loosen the soil and control moisture in time. Fifth, it is impervious to water for a long time. The roots of Cymbidium lose water, and the lower old leaves turn yellow. It should be watered thoroughly to keep the basin soil warm and moist.
