What is the reason for the whitish leaves of the junzi orchid

Clivia. Not only are flowering plants, but also leaves are beautiful ornamental objects. If there is a problem with the leaves of the Monarch Orchid, whitish or crooked, etc., what should I do, the following will analyze the reasons for the whitening of the leaves of the Monarch Orchid and how to solve other problems of the Monarch Orchid leaves.

This is because the light of the junzi orchid is not enough, and there is not enough sun, so the old leaves are white, and the newly grown leaves are also tender yellow, and the nightclub does not have a bright green and shiny appearance, just like the leek yellow of a large leaf. This is not a good sign, so move him to a sunny place to increase the light.

But be careful not to let it receive too much light at once, just like a person who has been in the dark for a long time and can't accept the light at once, otherwise he will be blind. We need to start by placing it in a bright place indoors, and gradually increase the light hours.

How to keep the leaves of the gentleman's orchid green.

There is a trick, which is to open the lid of the beer and let it stand in a cool place for about 3 days to let it rot, mix it with water in a ratio of 1:50, and often use this to wipe the leaves of the orchid, which can promote the photosynthesis of the orchid.

Let its leaves be evergreen and tender.

How to keep the leaves of the junzi orchid fat and shiny.

The organic fertilizer water should be mixed with water according to the ratio of 1:2000 and water, and the orchid should be watered and applied. At the same time, a layer of organic fertilizer is laid on the bottom of the pot, about 3 cm thick.

What to do if the leaves of the gentleman's orchid are not neat.

1.The placement of the Gentleman's Orchid should be: the vertical side faces north and south, and the horizontal side faces east and west.

2.If one of the leaves of the orchid grows crooked, which side is outward, cover half of the leaves with thick pieces of paper, and after a while it will grow on its own.

What is the reason for the yellowish-white leaves of the Monarch Orchid? How should it be resolved?

This is white spot disease, you should first cut off the leaves with disease spots on the Monarch Orchid plant, then change the pot and soil for planting (it is best to disinfect), and finally change the potting soil to prevent the Monarch Orchid in a position with good ventilation conditions, and you can spray some low concentration carbendazim or chlorothalonil.

Hello, Gentleman's Orchid Causes of whitish and thinning leaves:

1. Soil fertility is reduced, and all soil needs to be replaced.

2. Semi-dormant state in summer, high temperature and stuffiness, poor ventilation, so poor growth, resulting in thinning.

3. Excessive watering, waterlogging of the root system, resulting in poor absorption.

4. Too little sunlight, poor photosynthesis, lack of chlorophyll.

Top dressing outside the roots. Fertilization in this method is mainly to make up for the lack of nutrients in the soil, so as to solve the problem of lack of fertilizer in the plant, so that the seedlings grow fast and the flowers and fruits grow hypertrophied. Extra-root fertilization is to spray the dilution of fertilizer directly on the leaf surface of the plant with a mist, so that the nutrients can penetrate into the leaf tissues through the leaf epidermal cells and stomata, and then be transported to the whole body of the plant.

Commonly used fertilization varieties include urea, sea meal, potassium dihydrogen phosphate, etc. When spraying, it should be sprayed evenly on both sides of the leaf. Spray once in 4 6 days during the growing season, once every 2 weeks when semi-dormant, generally sprayed after sunrise, and should be stopped after the plant blooms, it must be noted that this method can only be used if the plant is found to be lacking in fertilizer.

If the plant is nutritious and grows vigorously, it should not be used.

What is the reason for the yellowish-white leaves of the Monarch Orchid? How should it be resolved?

The leaves of the orchid are white and thinning because they are exposed to too much light, which causes sunburn of the leaves, which initially manifests as white and green leaves, and then turns yellow, dry and rotten. After a sunburn, it is difficult to recover from sunburn, and appropriate treatment can be carried out according to the degree of sunburn.

If it is only a small area of sunburn, the sunburned part can be cut off, although it will leave a small hole, but it can avoid rotting and causing infection of the leaves. If the sunburn is on the edge of the leaf, or the tip of the leaf, you can cut off the sunburned part directly.

If the sunburn is very large, you can directly cut off this leaf, sometimes the sun is more serious, maybe all the leaves have sunburn, then you can directly cut off all the leaves, so that the Junzi orchid can re-emit the leaves.

If all the leaves of the gentleman are cut, watering must be careful to avoid watering the center of the leaf, otherwise it is easy to cause rot, and in addition, we should also pay attention to water control, so as not to cause rotten roots due to water.

1. Strict water control.

It is very likely that the white hair of the orchid is infected by overwatering, and the disease will spread very quickly in a humid environment, so it is necessary to stop all the watering and hydration work of the plant in time, control its water intake, and let it dry for about 7 days, waiting for the soil to dry out.

2. Prune diseased leaves.

When the soil is basically dry, the spread rate of white mold will be significantly reduced or even no longer spread, this is because the surrounding environment is too dry, moisture-loving bacteria can not survive and spread, take this opportunity to cut off all the infected leaves on the plant and destroy them, the infected leaves can no longer be recovered.

3. Prune the roots.

After pruning the diseased leaves, it is necessary to remove the potting soil that has been dry, and the dry potting soil is easier to remove - some, after the soil removal is completed, the root system of the plant will be carefully combed, find the wilted and diseased roots on the root system and cut them off, and put them in a cool place to dry slightly after disinfection.

In general, there are several cases, if the bottom leaf grows new roots from the leaf axil, making the leaf yellow is a normal metabolism.

One situation is that the leaf axils do not grow new roots and the leaves turn yellow, which is mostly due to soil quality, poor air permeability, too much fertilizer or poor watering and humidity control of the roots, which may make the leaves of the Junzi orchid yellow.

Water can not be watered, the root tip lacks water, it will make the leaf tip turn yellow and dry tip, in this case, it must be watered thoroughly, in summer, every 7 10 days at the bottom of the pot can sit a small pot of water, so that you can ensure that the water is watered, this is called the water immersion method.

Another condition is the appearance of yellow spots of varying sizes on both sides of the leaves, called brown spots.

This is mainly due to the fact that the soil is relatively grown, and the amount of fertilizer applied is too large.

Generally speaking, the potting soil should be made of humus, with good air permeability, especially in summer fertilization, thin fertilizer should be applied frequently, and fertilizer water should not be dripped onto the leaves, so as to prevent the occurrence of spot removal.

In another case, due to the abundant sunshine and high temperature in summer, if the orchid is exposed to the sun, solar fever will also occur, and the leaves will turn yellow and wilt in the heavy.

In summer, shading should be taken, a ventilated place should be placed, the shade avoidance degree should be 50, and the south window of the home can be shaded with a layer of gauze.

The white hairs in the middle of the leaves of the junzi orchid should be scale insects.

Scale insects are insects of the order Homoptera, the family Shield Scale, the female is wingless, and the feet and antennae are degenerated; The male has a pair of soft wings, well-developed feet and antennae, and stinging and sucking mouthparts. There are 6 common species, including Blowing Cotton Scale, Camphor Camphor Round Shield Scale, Bran Scale, Korean Ball Scale, Mulberry White Scale, and Kang's Mealybug.

Scale insects insert their stinging and sucking mouthparts into the leaf tissues of the orchid for life. Not only does it plunder a large amount of plant sap, it destroys leaf tissue, causing tissue discoloration and death.

It can be used with 40% dimethoate 1000 times solution, or 50% malathion 1500 times solution, or 255 imithion 1000 times solution, or 50% dichlorvos 1000 times solution, or deltamethrin 3000 times solution, spray, with Bika foliar fertilizer is better. Spray once every 7-10 days, 2-3 times in a row.
