What is the reason that the leaves turn yellow when the orchid is in bloom?

The reason for the yellow leaves of the Gentleman's Orchid is mainly due to improper management. There are several reasons for the yellow leaves of Junzi orchid:

1. The water is too large: the water in the pot is too long, and the leaves are easy to produce infiltration yellowing, which occurs at the tip of the young leaves, and the symptoms develop from top to bottom.

2. Lack of water: too dry, or watering half of the water every time, the old leaves should be yellow tips.

3. Hypertrophy: too much fertilizer is too concentrated, which will cause root burning and yellow tips of leaves.

4. Lack of elements and loss of green: If there is a lack of iron in the potting soil, the top of the leaves will turn yellow first. If nitrogen is deficient, the new leaves are yellowish-white.

5. Sunburn: After strong direct sunlight (summer), yellow spots occur on leaves, which is called sunburn. When dry at high temperatures (above 30), the leaves are also prone to yellowing.

6. Pollution: The leaves of the orchid should be kept clean, if it is splashed with dirt, the polluted place may turn yellow.

7. Frost damage: Frost damage occurs when the orchid is below 0, and the symptoms are still yellow leaves.

In order to restore the normal growth of the monarch orchid after yellow leaves, it is necessary to find out the source of the disease and take corresponding measures. The method is: dig out the whole Junzi orchid to check the roots, such as rotten roots, remove the rotten parts, re-cultivate with new soil, and pad a layer of fine sand under the roots.

The potting soil should be loose humus, and the pH value (pH value) should be neutral. The soil is not dry or wet, and it has good aeration. Junzi orchid likes weak light, except for winter, summer should be placed in a place of half shade and half yang, avoid direct sunlight.

If it happens"Lack of green disease"Liquid fertilizer (such as alum fertilizer water) can be added, the main point is that the amount is less and more often, be careful not to splash the fertilizer or mud on the leaves, and the stems, such as splashing on the leaves, should be washed off with water in time. Solid fertilizers should also be applied in direct contact with fleshy roots as well.

What to do if the leaves of the gentleman's orchid are yellow.

If the Gentleman's Orchid appearsThe entire leaf turns yellowsituation. Cause: It may be due to bright light exposure.

Too strong sunlight will burn the leaves of the orchid, causing the leaves to turn yellow. Treatment: Cut off the yellow leaves and shade the orchid to alleviate the yellowing of the leaves.

2.The leaves of the orchid will also appearThe edges of the leaves are yellow, and the tips of the leaves turn yellow or scorchedsituation.

Reason: The phenomenon of local leaf yellowing is mostly caused by excessive watering, or it may be due to incorrect fertilization, too concentrated fertilizer, causing root burning and local yellowing of the leaves of Monarch OrchidIt can also be caused by poor soil ventilation, poor breathing and poor drainage of the roots, or insufficient ventilation of the maintenance environment.

Treatment: Do a good job in water and fertilizer management, reasonable watering and fertilization, and avoid excessive wetness of potting soil or burning roots with thick fertilizer;It is also necessary to pay attention to frequent ventilation of the orchid so that it grows in a well-ventilated environment, and pay attention to the choice of soil.

3.Gentleman's OrchidThe leaves have macula, which is mainly manifested as yellow or yellow-brown spots on the leaves, and gradually expand, harming the leaves.

Causes: Leaf spot or anthracnose, or insect infestation caused by pests.

Treatment: You can choose the right pesticide for spraying**, and in the daily maintenance, do a good job of disease prevention measures, prevention and control.

Orchid has normal metabolism。Sometimes there will be yellowing, grayish, yellow and other phenomena, and because of normal metabolism, the old leaves at the bottom of the orchid grow new roots from the leaf axils, and continue to grow, resulting in yellowing of the leaves.

How to distinguish: If it is a long maintenance time of Junzi Orchid, it is a normal metabolic phenomenon. However, if the new leaves and young leaves appear yellow, gray yellow, or yellow, it may be caused by improper watering, too much sunlight or too much fertilization.

Treatment: The leaf yellow caused by normal metabolism does not need to be too worried, as long as the old leaves of the monarch 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 fertilizer can improve the yellowing of the leaves of the orchid.

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 there is not enough light, if you put it in a place with no light or low light, the half moon is yellow enough.

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

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.

1. Overwatering.

1. Reason: The root system of Junzi Orchid is a fleshy root, and it is very afraid of blisters. If it is overwatered and water accumulates in the soil, it will soak its roots and cause its leaves to turn yellow.

2. Treatment: Take it out of the pot first, and use scissors to cut off the blackened roots and yellowed leaves. Then plant it in new soil that is free of standing water, and pause watering for a while until it starts growing again.

2. Treatment: first cut off the leaves that have turned yellow, and then build a shading net where it is raised. When the light is very strong, use a blackout net to block out some of the sunlight.

2. Treatment method: first use a large amount of water to irrigate the soil and wash away the residual flower fertilizer. Then place it in a ventilated location to dry. Do not apply fertilizer or water until it returns to normal.
