What s going on with the whitish stuff inside the orchid planting material?

Is it harmful for orchid planting material to grow white filaments?

Use practical experience to take you to raise the flowers at home. When we plant orchids, after planting the orchids in pots, sometimes there is some planting material left. If these planting materials are not dried in time, they are stacked in one place or placed in a container, and after a few days, they are likely to produce some white filaments, as the saying goes, "white hair".

In fact, this white filament is gone when it is put in the sun, and it is not necessarily a virus bacteria. In many cases, it is just a mold produced by the normal fermentation of humus material. And this mold only occurs in a specific humidity and temperature environment, and this fermented mold is not only harmless to orchids, but also has many benefits.

Just like the tofu we eat, it is also a kind of white filamentous mold that will be produced during the fermentation process. After the fermentation of this mold, the protein in the tofu milk is more easily absorbed by the body.

So, how does this white filament come about? The production of this white filament is due to the fact that the humus material in the orchid planting material is not completely fermented. Second, because the specific moisture content and temperature are suitable, the planting material will produce this white filament.

Some of the humus materials we use, such as pine bark, peanut shells and other materials, are not fully fermented, the moisture content of the materials is less than 30%, and the ambient temperature is higher than 20 degrees.

If the water content of the planting material is more than 30% after potting, and the ventilation conditions are relatively good, even if the planting material in the pot is not completely fermented, this filament will rarely appear.

If the planting material has not been strictly sterilized before potting, it is recommended to sterilize the planting material again or replace it with a fully fermented and sterilized planting material. Pay attention to the summer breeding of orchids, in the case of good ventilation conditions, the moisture content of the planting material in the pot should be between 30% and 50%, and the air humidity of the orchid environment should be about 70% to 80%. In this way, it is more conducive to the normal growth of orchid sprouts.

What is whitish in orchid planting? What to do? You'll know after reading it.

Summary. Good morning, orchid leaves have white spots, and it is necessary to spray dimethoate solution in time for effective control. When caring for orchids, avoid strong direct sunlight and ensure proper sunlight scattering.

Water the orchids in time, do a good job of water replenishment, and water thoroughly every time. Prune orchids to enhance air circulation and avoid the growth of bacteria and insect pests.

1. Prevention and control methods for white spots on orchid leaves.

The white spots on the leaves of the orchid are due to the fact that the plant has suffered from scale insects. If not controlled in time, the leaves of the orchid will be quickly eroded, and the leaves will turn yellow and fall off. It is necessary to spray dimethoate solution on damaged leaves in time, or wipe the surface of the leaves after dilution with vinegar for effective prevention and control.

Second, the maintenance of orchids.

Orchids like a semi-shady environment, can not be directly exposed to direct sunlight, the environment is dark, orchids will migrate, leaf growth is slow. Orchids need to be maintained in a ventilated and bright place to ensure sufficient sunlight scattering, and the light is strong in summer, so it is necessary to do a good job of proper shade protection to avoid sunburn on the leaves.

Orchids like a moist environment and need to be watered in time to replenish water. Water the orchid thoroughly every time to avoid root rot caused by stagnant water. Summer temperatures.

The entire leaf is whitish and shows signs of wilting.

No luster. Spray some nutrient solution.

If the leaves on the back of the orchid are white, the first foci is wide, which is mostly caused by the alkalization of the potting soil. At this point, a foliar spray of ferrous sulfate can be given once a week to relieve symptoms. Alum fertilizer water can be used to prevent soil alkalinization when fertilizing.

Don't worry about the white leaves of potted orchids, the little florist will teach you two tricks, which are simple and practical, and then there is the orchid infected with scale insects. The scale insects will suck the sap of the orchid, which will eventually cause the yellowing and weakening of the leaves of the plant. Scale insects prefer a dark, damp and poorly ventilated environment, at this time, do a good job of ventilation to reduce the chance of disease.

Powdery mildew, onset of symptoms: Powdery mildew is a fungal disease, bai is a flower plant on the subject

The common diseases mainly occur in the leaves of the plant, and can infect the young leaves, young shoots, young shoots and flower buds of the plant when it is severe, and the damaged flower varieties mainly include dozens of species such as Yueji, rose, rose, peony, peony, chrysanthemum, etc. The prominent feature is that a layer of powder appears on the back or both sides of the leaf at the time of onset, and in the early stage of the disease, a nearly round or irregularly shaped white pink spot appears on the infected site, and it is slightly greenish or deformed. Under the right conditions, the pink spots expand rapidly and join together to form patches, so that the leaves are covered with white powdery mold.

In the later stages of the disease, the diseased leaves will be shrunken and curled back, and the flowering period will be significantly shortened or the flower buds will not be normal. In severe cases, the plants are short, the flowers are few and small, the leaves are shriveled and dry, and even the whole plant dies.

Old Times Chaozhou]: I have a question I want to ask, the new leaves of orchids have been white, and a few have dried up.

Memories of the end of summer]: The flowers are so well raised, you still need to ask for advice, and all you propose are incurable diseases.

Old Times Chaozhou]: Solve ordinary problems by yourself, haha, I have tolerated it for a long time, thinking about whether it will become green when I grow up, and if I raise it the same, this one will not.

Memories of the end of summer]: the same variety? The same tube is frank and branched, leaf albino is relatively rare, of course diseased leaves can be removed, are you sure the root system is okay, the leaf albino of the orchid has not been seen by the squad leader, and he has not found a post to introduce it.

can only provide a few ideas, such as mutation, I have seen the introduction of orchid flower color variation but I have not seen the introduction of leaf variation; For example, the lack of trace elements (nitrogen or iron) has seen iron deficiency in different plants, some of the leaves are yellow and white, and some of the leaves are completely white (geranium).

Old Time Chaozhou]: Wait for me to see the roots at night, I don't have time to get it now. Guess that if there is a problem with the roots, so many bamboo shoots should not be burst. A little confused.

Memories of the end of summer]: If there is no problem in checking the root system, remove the spotted leaves and raise them.

Let the old time Chaozhou]: Okay, thank you for the squad leader's advice.

Memories of the end of summer]: The squad leader didn't help this time, no thanks.

End of conversation! Uncle Gardener's Tips].

The appearance of whitish orchid leaves is relatively rare, about this related knowledge and sticker Uncle Gardener understands less, some flower friends say that there is no lack of genetic mutations, illness and other conditions, Uncle Gardener suggests that you can first find the reason from the usual maintenance, such as whether there is medication, fertilization, and light recently. Welcome flower friends who understand this knowledge or have orchid leaves whitish to come to the florist uncle flower friends group to share and communicate!

Summary. Dear, there are probably two possibilities for white powder. One is powdery mildew infected by germs; The second is caused by scale insects.

Dear, there are probably two possibilities for white powder. One is powdery mildew infected by germs; The second is caused by scale insects.

For the first type of pathogenic, bactericidal drugs (powdery rust, antimycin, nitrijuzole, bugaolipid film emulsion, etc.) can be used to remove the disease, and a variety of drugs can be used to avoid the development of drug resistance. At the same time, the ventilation management should be strengthened, and the orchid leaves with serious diseases should be cut off and destroyed in time. Do not pour water on the leaves when watering to prevent more contamination with the flow of water.

The second kind of scale insect is also a common pest of Yanglan, which is generally used to kill phosphorus and shell, which is targeted. The scale insect is more stubborn, it is necessary to scrape off the white powder on the orchid leaf first, and then spray the diseased plant.
