What is the reason for the white stuff growing on the branches of the Burmese osmanthus flowers?

When you buy your osmanthus with soil balls or in the original pot, do you buy it in a pot? If it is with soil balls, pay attention to whether it is the soil balls when they were originally planted, or the soil balls on the vendor's fake bag; If it is bought with a pot, have you noticed whether it is indeed the original pot, if it is the original pot, the tree will not come out of the pot with the stem, the pot is relatively compact, and there is grass or moss, turn over the hole at the bottom of the pot, and a small number of roots should be stretched out from the leakage hole, otherwise it is temporarily planted. It is difficult to survive after buying back the fake soil balls and the osmanthus flowers in the fake original pot.

How to raise osmanthus well: 1 Osmanthus likes slightly acidic soil Potted plants can be mixed with 5 parts of mountain mud, 3 parts of humus soil, and 2 parts of sandy soil, or half of humus and sandy loam soil as culture soil. If the soil is too acidic, it will grow slowly and the leaves will wither and yellow.

If alkaline soil is used, after 2 to 3 months, it can lead to leaf withering and even death. 2 watering should be timely Osmanthus watering should master "two less and one more", that is: less watering before the occurrence of new shoots, less watering on rainy days, and more watering in dry weather in summer and autumn.

It is advisable to keep the water content of the potting soil at about 50 for ordinary watering. On rainy days, it is necessary to drain the water in time to prevent the water in the pot from rotting the roots, otherwise it is easy to "flood". 3 skillfully apply top dressing osmanthus likes pig manure.

There is a flower proverb "to get the fragrance of osmanthus flowers, prepare more pig manure tanks". If you can get out of the room from the early spring osmanthus, that is, apply the well-rotted and thin pig manure, apply it once every 10 15 days in April and May, apply it once every 7 10 days in June and July, and apply it for the last time in early August, then the osmanthus grows luxuriantly, blooms more and is fragrant. There is no pig manure in the city, and you can use well-rotted cake fertilizer.

If the fertilization is insufficient, there are fewer branches, fewer flowers, and not fragrant. 4 Proper pruning Osmanthus has a well-developed root system, strong germination, and adult osmanthus trees are plucked twice a year. Therefore, in order to make osmanthus flowers flourish, it is necessary to prune properly to maintain the physiological balance of reproductive growth and vegetative growth.

The new leaves of osmanthus are always not growing well, and they are dense, what is the reason?

Summary. You can mix alcohol and water in a ratio of 1:20 to make a sterilization solution, spray it on the branches with long white hairs, and need to be sprayed once every 1 week to achieve the effect of killing insects.

Dear, the white hairs on the osmanthus branches are due to infection with scale insects. It will quickly spread out and erode the leaves, absorbing a large amount of leaf sap, causing the leaves to wither and fall off. Beetles multiply in large numbers and can also induce bituminous coal disease.

In addition to manual pest control, it is necessary to spray dichlorvos solution in time for effective prevention and control, and remove the diseased branches and jujube in time.

You can mix alcohol and water in a ratio of 1:20 to make a sterilizing solution, and spray the locust on the branches with white hairs of lead hand liquid, and you need to spray it once every 1 week to achieve the effect of killing insects.

Hope mine is helpful to you [Bixin].

Summary. Lack of light.

Usually need to be cultivated in the sun, if it is placed in a cool place to cultivate, it will cause osmanthus to be unable to photosynthesize, resulting in poor growth, and may even cause pests and diseases, and appear white leaves and other symptoms.

What is the cause of whitish on the trunk of the osmanthus tree.

Hello, I have seen your question, please wait a moment, I am sorting out the answer for you.

If it is cultivated in a cool place, it will cause osmanthus to be unable to photosynthesize, resulting in poor growth, and may even cause pests and diseases, and symptoms such as white leaves.

Soil discomfort each plant has different soil requirements, osmanthus has particularly strict requirements for soil, it needs to be planted in loose soil, good ventilation and water retention, high fertility, but also with acidic soil, if the soil is too wet, but also with alkaline, it is easy to induce osmanthus to suffer from pests and diseases, resulting in whitening, smaller, falling off and other symptoms.

Pest control flower leaves whitish what causes, is likely to suffer from pests and diseases, osmanthus common pests and diseases are leaf spot, coal stain disease, red spiders, aphids, etc., these pests and diseases will cause the leaves of osmanthus to white, yellow, fall off and other symptoms, and even cause the death of the whole osmanthus plant, the harm to osmanthus is very great.

Your description is accurate, and there should be two scenarios:

1. White silk disease caused by bacterial infection. It is characterized by the appearance of a white silky substance at the base of the stem or root of the plant at the beginning of the disease, and then the leaves gradually wither from the bottom up. The temperature is too high, the air is too wet, and the soil is waterlogged, which makes it easy to get this disease.

You can pick up the white object and if you find a worm inside, you can get rid of the disease.

The solution is to improve the temperature and humidity, control the watering, and use lime powder.

** and prevention.

2. Insect larvae with silking function are harmed, such as various mites.

Moths and mealybugs are characterized by forming white flocculent or reticulated substances at the base of plant stems, leaves, and buds.

The identification method is to pick up white objects with thin branches, wires, etc., and you can see white, black, or flesh-red larvae wriggling inside.

Killing method: It is not recommended to use pesticides, you can go to the flower shop to buy targeted or broad-spectrum flower special insecticides. At first onset, it usually works. The security would be better.

3. In fact, the above two problems are more common in summer and autumn, especially for woody flowers and trees. In addition to osmanthus, I have recently seen it on tea, bamboo, and fruit trees planted in some communities and flower beds. However, similar problems occur in large outdoor spaces, and plants can generally heal themselves with the change of seasons and climate.

As a family potted plant, the way to prevent it is: try to place the woody potted flowers in a well-ventilated, sunny and humid place, basically use the method of watering when you see dry and wet, and watering thoroughly, in early spring and late autumn, prune diseased branches, dead branches, weak branches, and long branches.

4. Scale insects.

Most of them harm the dorsal part of the leaf of the mosaic leaf, not the root and trunk of the leaf.
