Yellowing of the leaves of the orchid? What causes the yellowing of the leaves of the Gentleman s Or

Your gentleman Langan is already rotten, and the reason for this is that the water has been poured too much, and he can only be a dead horse as a live horse doctor. Take it out and peel off the discolored leaves may only have a few leaves in the center is good, cut off all the rotten roots with a blade, change the soil and repot it after a day of drying, you can't water, the soil is damp, if you can send leaves, it means that you are alive.

Here's why:

1. Lack of water. If the leaves of the orchid are yellow and drooping, it is generally caused by lack of water. At this time, we should carefully check the situation of the soil in the officialdom, replenish water in time, and properly loosen the soil to ensure the respiration of the roots.

2. The light time is too long. If the light time is too long, it will also cause the phenomenon of yellow leaves in the monarch orchid, and the whole leaf may be obviously yellowed at this time. At this time, you can move the orchid to a cool and ventilated place for maintenance, and cut off the yellow leaves.

Wait until the plants have regained their growth before daily cultivation.

3. Fertilizer damage. If the orchid is fertilized, it is easy to cause the leaves to turn yellow or even wrinkled. It is usually due to excessive fertilization and damage to the roots.

4. Pests. The occurrence of pests and diseases is easy to make the leaves of the junzi orchid appear yellow spots, etc., which is to remove the insects as soon as possible, in addition to spraying drugs, but also to cut off some leaves that suffer from serious pests and diseases, so as not to affect the healthy leaves.

1. When the whole leaf of the orchid turns yellow, it will not only affect the ornamentation of the orchid, but also be detrimental to the growth of the orchid. At this time, the yellow leaves should be cut off and the junzi orchid should be shaded to alleviate the yellowing of the leaves.

2. The appearance of local leaf yellow in Junzi Orchid is actually mostly due to improper daily maintenance, and it is necessary to do a good job in the daily maintenance of Junzi Orchid. Do a good job in water and fertilizer management, reasonable watering and fertilization, avoid excessive potting soil or thick fertilizer to burn the roots, so that the leaves of Junzi Orchid are yellow. It is also necessary to pay attention to the frequent ventilation of the orchid so that it grows in a well-ventilated environment, and pay attention to the choice of soil.

3. When there is a leaf lesion due to diseases and pests, it is necessary to choose the appropriate method according to the onset of the disease, and you can choose the right pesticide for spraying, and in the daily maintenance, do a good job in the prevention of diseases, focusing on prevention and control.

4. The leaf yellow caused by normal metabolism does not need to be too worried, as long as the old leaves of the junzi orchid are cut off to keep it beautiful. However, if the Junzi orchid has the symptoms of yellow, gray yellow, and weak yellow, it is also necessary to do a good job of daily maintenance. Pay attention to watering and avoid stagnant water; Proper shading; Thin application of diligent fertilizer can improve the yellowing of the leaves of the junzi orchid.

There are two reasons for the yellowing of the leaves of the orchid, one is the problem of light, and the other is the problem of ventilation.

Junzi orchid is a semi-positive flower, like relatively weak scattered light, not tolerant to strong light, too strong light is easy to cause sunburn, light leaves from green to yellow, heavy leaves dehydrated and dry death.

If the light is too dark and the light is not enough for a long time, the leaves will lose their luster, the old leaves will be dark green, and the new leaves will become thinner and yellow or yellow-green. At this time, the orchid should be moved to a slightly stronger place or supplemental light. The leaves of the orchid have phototaxis, and they should be stocked to the light in order to maintain the shape of a line on the side and a fan on the side.

<>1. Uncomfortable light.

Orchid is not tolerant to strong light and likes to grow in a cool environment, so if the light is too strong, it is better to like a plant in a cool environment, and strong direct sunlight will make the leaves of Monarch Orchid sunburnedThe leaves of the orchid will turn yellow, so it is best to maintain the orchid in a bright place, but also do not maintain the orchid in a place where there is no sunlight, because photosynthesis is carried out normally and sunlight is needed.

2. Improper watering.

The growth of Junzi orchid needs to replenish water in time, long-term non-watering will easily lead to plant drought, the leaves of Junzi orchid will appear yellowing, watering should control the amount of water, not only to ensure that the soil is moist, Junzi orchid absorbs enough water, but also to prevent excessive watering and water accumulationThe roots of the orchid are easy to rot when soaked in water, and after the roots rot, the nutrients and water are not well absorbed, and the same will be yellow leaves, and if you water too much, you can use a paper towel to absorb excess water.

3. Improper fertilization.

The original nutrients in the soil alone are not enough to supply the growth of the orchid, and it is necessary to fertilize it in time and supplement it with nutrients regularlyNeed to understand the growth habits of the orchid, generally half a month to apply fertilizer is better, fertilization selection of the orchid good absorption of the bamboo green green leaf king plant nutrient solution, to meet the absorption of nutrients by the orchid, the use of non-diluted nutrient solution is also very convenient, fertilization can not be too frequent, easy to cause fertilizer damage, the same will affect the health of the orchid.

If the old leaves are yellow, it is normal, and if the new leaves are lacking in nitrogen fertilizer.

I think there are the following reasons: First, the soil is too dry and lacks water. The second is normal defoliation. The third is disease.

The main reasons for the yellowing of the leaves of the junzi orchid are:

The temperature is uncomfortable, especially low and then high, and the temperature difference is large. It is advisable to keep it above 5, preferably not higher than 30.

Improper watering, not drought or keep wet. It also includes long-term water accumulation in the bottom tray.

If you don't have enough light, if you put it in a place with no light or low light, half a moon is yellow enough.

Spider mite damage, the leaves should be wiped frequently, one is to reduce dust, the other is to reduce the harm of red spiders.

Do not place around radiators or air conditioners.

If there is a problem with the substrate that the merchant puts in the flower pot, check whether there is anything inappropriate! Such as lime, paper scraps, clayey soil, and even large gaps and water leakage.

My family's Junzi Orchid is also often like this, and proper and careful care should make a difference.

Long-term lack of water will cause the leaves to turn yellow and scorch, and hurt the roots. At this time, it is necessary to observe the condition of the soil, water it when it is dry, not too much each time, and keep it slightly moist. You can also spray water on the leaves to keep them moist.

First, the light is too strong.

In fact, the orchid is not tolerant to strong light, it is a better plant that likes a cool environment, strong direct sunlight will make the orchid appear yellow, and the leaves are easy to wither and yellow.

How to solve: shade the plant or place it in the semi-shade for maintenance, cut off the yellow leaves, pay attention to ventilation, and not too stuffy.

Second, there is a lack of light.

Although some plants like shade, but long-term exposure to dark places will also cause yellowing of leaves, although the orchid itself is a plant that prefers a cool environment, but no light at all, it is not good.

How to solve: Put the orchid in a bright, semi-shady place, or use a fluorescent lamp to supplement the light.

3. Too much water.

Excessive water, watering too much, water at the bottom of the pot, the top of the young leaves begin to turn yellow, and the leaf core of the junzi orchid can not be watered, if the ventilation conditions are not good, it is easy to lead to excessive water.

How to solve: Stop watering and pay attention to controlling the amount of water when watering. Loosen the soil frequently to make the potting soil breathable. If there is water at the core of the leaf, use a paper towel to suck out the excess water droplets.

There are many reasons for the appearance of yellow leaves, although it is easy to rot the roots with more water, resulting in yellow leaves, and less water will also turn yellow, and the air in the maintenance environment is too dry, or the soil permeability is too poor, especially the application of thick fertilizer and raw fertilizer, which will lead to yellow leaves:

1.If the water stains are yellow, the water accumulation in the pot for too long will cause the leaves to become infiltrative yellow, and the part of the occurrence is the tip of the young leaves, and the symptoms will develop from top to bottom.

2.Lack of water will turn yellow, the potting soil will be too dry, and the old leaves will turn yellow if you water half of it.

3.Hypertrophy and yellowing, excessive fertilization, overgrowth, and excessive concentration will cause root burning, and the leaves will be yellow and tipped.

4.Iron deficiency yellowing, if there is an iron deficiency in the potting soil, the tip of the leaf turns yellow first. If nitrogen is deficient, the new leaves are pale and yellowish-white.

5.Sunburn yellowing, after strong direct sunlight (summer), the leaves develop yellow spots, which is called sunburn. When dry at high temperatures, the leaves are also prone to yellowing.

6.The pollution is yellow, and the leaves should be kept clean, if the dirt is splashed, the polluted area may turn yellow in a dotted shape.

7.Frost damage is yellow, and frost damage occurs below 0, resulting in yellow leaves.
