Why is the bark of the osmanthus tree cracked and the solution is sought

Osmanthus tree, the bark cracking, may be in the transplanting process, there is a problem, should be timely, apply fungicide for treatment, to avoid the appearance of germ invasion and other problems. After planting, apply the root of the leaf in time to promote the growth of the root system.

It's not too much of a problem, the osmanthus will grow slowly. You can wrap the trunk with straw and water it in moderation in the summer. If the leaves are not dense, the tree has not yet recovered, so take good care of it and fertilize it appropriately.

1. Put on the pot. The pot is generally selected in spring or autumn, and it is advisable to have a rainy day. Before transplanting, it is necessary to lay a good soil ball to ensure the survival rate.

The soil in the pot should be loose and fertile, acidic soil. The soil ratio is 2 parts of humus, 3 parts of sandy soil, and 2 parts of well-rotted cake fertilizer, mix them evenly, and then pot or change pots.

2. Light and temperature.

South of the Yellow River, it can overwinter in the open field. North of the Yellow River, it is necessary to overwinter indoors, place it in a sunny place, and keep the indoor temperature above 5 degrees, but not more than 10 degrees. In April of the following year, it was moved outdoors, first placed in a leeward and sunny place for maintenance, and then gradually moved to a ventilated and sunny place after stable growth.

When the light is insufficient during the growth period, it affects the differentiation of flower buds.

3. Shaping and pruning.

Depending on the tree, the large frame should be set according to the posture of the tree, and other tillers, over-dense branches, long branches, cross branches, and diseased branches should be removed to ventilate and transmit light. For those who are strong and weak at the top of the tree, the upper branches can be truncated 1 3 to make the overall tree strong, and at the same time, apply callus antiseptic film at the pruning mouth to protect the wound. After pruning, pay attention to the water-soluble fertilizer of fertile leaves.

If it is only a small area of cracking, you can wait for the bark to dry up, peel off the dry part, and apply charcoal. To prevent insect bites, if the area of rupture is relatively large, potassium permanganate can be used first.

Sterilize or copper sulfate.

It's okay, then wash with purified water, then wrap it in sterile vellum and cover it with plastic wrap.

1.When the damaged area is less than 10 square centimeters, after the bark is dried, peel off the dry part and apply charcoal to prevent insect bites.

2.When the damaged area is greater than 10 square centimeters, it is newly broken**. Disinfect with potassium permanganate or copper sulfate, wash with purified water, then wrap in disinfectant paper and cover with plastic wrap.

3.When the damage area is 10 square centimeters, if it is a small osmanthus seedling, the treatment method is different due to the long-term injury of the bark. Dead skin is removed, disinfected with potassium permanganate, and washed with pure water.

Osmanthus tree. Precautions for breeding.

1 potted osmanthus plant per culture.

It needs to be replaced every two years to ensure that the soil is loose and nutrient-rich. During the annual plant dormancy, remember to prune overgrown branches and dead branches to ensure proper plant growth.

If you can't buy organic fertilizer, rotten fertilizer, etc. during the fertilization process, you can irrigate a small amount after rotting and fermenting rice water, beer, tea, etc.

What kind of disease is the birch bark that will send out the trunk, and how to cure it? It is possible to say that the number of years of this osmanthus is relatively long, so there is an immediate phenomenon in it, that is, it is bitten by insects.

Hello dear. The wound has completely healed when viewed from the phloem around the necrotic part of the trunk. The necrosis is mainly caused by damage during lifting and transportation.

Excessive flowering and insufficient water and nutrient supply around the Mid-Autumn Festival are also one of the reasons for the drying up of newly planted osmanthus flowers. In addition, it is more reasonable to minimize the use of chemical fertilizers when planting, and wait for it to pass a growth cycle before fertilizing. Now it is necessary to clean up the dry branches and leaves of osmanthus, and use root rot and other root irrigation treatment.

2 bags should be hung on the infusion bag such as "root power" to observe the speed of its infusion, and the main role is to maintain its moisture and nutrient balance. After the wound site is cleaned, a callus coating can be applied evenly to prevent the wound from drying out and promote healing. In the later stage, it can be wrapped with non-woven fabric or straw rope, etc., and the temperature is still high recently, and the canopy needs to be covered with shade nets.

Dear, <>

The above is the answer that I can summarize for you, I am very happy to serve you, please give me a thumbs up, thank you very much for your <>

I hope mine is helpful to you, and then I hope you are happy every day, have a good life<> and good luck always accompany you<>

Summary. It shows that the osmanthus tree is growing.

It shows that the osmanthus tree is growing.

Excuse me, but please go into more detail?

There are many reasons for the bark of osmanthus to open and crack, 1. Growing too fast: when the plant fertilizer and water supply is sufficient, the xylem grows faster, but the phloem on the periphery does not keep up, resulting in the cracking of the bark. Cons 2, Sunburn:

In summer, strong sunlight can easily burn the bark and form cracks. This kind of cracking is especially prone to occur after rain and occurs in one direction, i.e. on the sunny side, southwest and south of the trunk. 3. Frost damage

In late autumn or early spring, the weather suddenly becomes cold and warm, and the temperature difference between day and night is large. When the temperature drops suddenly, the bark cools and shrinks rapidly, causing a huge difference in the tension between the inside and outside of the bark, and cracking from the outside to the inside. 4. Alternating between hot and cold:

One cold and one hot cause branch cortex and cambium tissue necrosis, discoloration, in severe cases, the bark is sunken, dry, cracked, phloem and xylem are separated, and this situation is easy to occur in spring. 5. Pests and diseases: such as whether there is glue flowing, mildew and discoloration at the cracks, whether there is insect hole powder, etc., to determine what pests and diseases affect the bark cracking.
