Question 1: In which month is camellia suitable for pruning? Moderate pruning of camellia, especially potted camellia, can make camellia grow compact and robust, and lay a solid foundation for producing high-quality flowers. So when will the camellia be pruned?

First, the pruning time of camellia

The best time to prune camellias is generally about one month before new buds sprout. Fujian, Jiangxi, Yunnan, northern Guangdong and other southern regions can be pruned about 20 days before the Spring Festival (that is, about 65438 solar calendar1mid-October), and low-altitude areas in the Yangtze River basin can be pruned before and after the Spring Festival. Neither the south nor the Yangtze River basin should be pruned too early or too late. The weather is too cold to prune plants too early. If it is too late, camellia buds will consume a lot of nutrients and grow badly that year.

Mastering the pruning period of camellia is actually a method to correctly master the pruning of camellia according to the different flower bud differentiation periods, which is the key. According to the difference of flower bud differentiation time, camellia can be divided into two types:

1, summer-autumn differentiation type. Most camellias usually bloom in spring, and their flower buds begin to differentiate in the summer and autumn of the previous year, so they must be pruned after flowering. If pruning is carried out in winter and spring, many flower buds will be cut off. If pruning is too late, these unwanted flower buds will consume a lot of nutrients, thus affecting the quality and quantity of flowering;

2. Differentiation in that year, a few species of camellia bloomed in the autumn of that year, such as well-known domestic species of autumn peony and flower peony, which generally bloomed in the middle and late period of 10. It does not need a vernalization period of summer and autumn differentiation (that is, low temperature time), but directly blooms in the same year. The differentiated camellia that bloomed in the autumn of that year, its flower buds were formed and blossomed on the new shoots of that year, and there was no low temperature, so this variety of camellia could be pruned during the dormant period (although this variety of camellia was less).

There are actually three types of flower bud differentiation. In addition to the two mentioned above, there is also a "multi-differentiation type", which does not conform to this article, but I want to mention it by the way here. Multi-differentiation refers to flowers that can be picked many times in a year, and each time they are picked, they will differentiate into flower buds. As we all know, the Chinese rose is such a flower. The first buds in spring were formed last year. As long as new branches keep growing in a year, they can keep blooming. Therefore, in the growing season, when the flowers wither, they should be pruned immediately to promote the axillary bud germination under the incision, and then draw new flower branches to prepare for re-flowering.

Second, the camellia pruning method

As for the pruning of camellia, because of its slow growth, most articles on camellia planting technology suggest that camellia should be pruned less or not. In fact, this statement is incorrect, because the development of modern agricultural technology has improved the growth rate of camellia, and the morphology of different varieties is very different. If not trimmed, it is difficult to form a beautiful crown, and the ornamental value will be greatly reduced.

Third, the role of camellia pruning

Before introducing pruning technology, we should first understand the significance of camellia pruning, which has two main functions:

1, which makes the shape and crown beautiful and improves the ornamental value.

2. Prune weak branches, keep strong branches, promote new branches and improve plant vitality. Many friends cut camellia before they knew the function of pruning, and the consequences can be imagined!

Fourth, pruning technology.

According to the two functions of camellia pruning and the characteristics of different varieties, different pruning methods should be adopted:

1. For fast-growing upright varieties, such as "Red Green Treasure", "Oriental Bright" and "Big Cinnabar", the height of about 1/3 is trimmed from the upper part by "truncation" method, and the weak branches that block light in the middle are cut from the roots, and the fast-growing ones are cut low and the slow ones are cut less. After pruning, this variety will lose about 1/3- 1/2 branches and leaves. After pruning in this way, the growth rate of camellia will be obviously accelerated in the second year, forming a beautiful crown.

2. For varieties with normal growth, slow growth and good natural morphology, such as "Yuanyang Fengkou", "Eighteen Singles", "White Swan" and "Sai Peony", it is only necessary to cut short the branches that grow too fast and affect the appearance, so as to keep them consistent with other branches, or cut off the weaker branches in the diseased branches. The terminal buds or buds of healthy branches that have not been pruned should be erased to promote their bifurcation and keep them consistent with the pruned branches.

3. For varieties with soft branches, large crown and insufficient height, such as "five-color tea" > >;

Question 2: Must camellia be pruned after flowering? Pruning and shaping Camellia oleifera is an essential technical measure in Camellia oleifera management, and its main functions are:

(1) Improve the ventilation and light transmission conditions of trees, improve the photosynthetic capacity of leaves, and reduce the excessive nutrient consumption of diseased and waste branches.

(2) Improve the health status of Camellia oleifera plants, restore tree vigor, restore tree vigor, and reduce the spread of diseases and insect pests.

(3) Molding camellia into various desired tree shapes to improve the ornamental effect. Camellia can be pruned all year round, but the ideal time should be after flowering and before new buds sprout. Due to the different flowering periods of different varieties, the pruning and setting time can be extended from 65438+February to February-March of the following year. When pruning and setting, the following principles should be mastered: ① Cut off diseased dead branches, clustered branches, cross branches and overlapping branches, and cut the mouth smoothly without leaving any residual piles. ② Leave 3 branches per plant. Keep the dominant branch on each branch. (3) the branches that are too high should be retracted and trimmed, so that new buds will grow at the lower part of the incision and the plants will become fuller. (4) After pruning, the sprouting buds should be erased in time. Generally, it is advisable to leave two buds at each germination point. ⑤ According to the requirements of cultivation, camellia can be trimmed into different shapes, such as round head, straight tube, short crown, fence or other geometric figures. This kind of shaping method has great pruning performance, and the sprouted branches after pruning are robust, which requires multiple pruning to control the tree shape. ⑥ Camellia pruning should be carried out continuously for many years, and the weak direction should be supported and the strong direction should be controlled according to the tree shape, so that the plants can develop in a balanced way and achieve the effect of beautiful flowers.

Question 3: How to prune the branches of potted camellia is divided into thinning and dwarfing. Intercropping is to cut off some branches inside the plant from the base when the plant is too dense. The objects of thinning are diseased branches, dense branches, dead branches, cross branches, parallel branches, inward branches and overlapping branches.

When pruning, cut the branches obliquely, and the incision should be flush with the base of the branches, leaving no residual piles. Scissors should be sharp to smooth the wound and facilitate healing. In order to make trees shorter, pay attention to the direction and position of buds when pruning. Because the inner buds of camellia are upward and the outer buds are outward, branches can be cut off and buds can be left as designed. The first bud left on the branch bud should be on the other side of the blade, and the top of the inclined plane should be about 3 mm higher than the bud base to prevent it from being too high or too low. Balance should be maintained between the main branches, so that the stems, branches and leaves of camellia can be developed reasonably.

When shaping and pruning, we should pay attention to choosing lateral buds with outward branches and moving scissors at the top. This will make the whole branch more and more compact. If you trim the lateral buds that grow upward or downward from above, you will control the crown shape or droop of the tree. For some disorderly growing camellia varieties, it is necessary to keep pruning frequently to make them have a certain shape.

However, if Yunnan Nanshan tea branches grow sparsely and irregularly, it is easy to suffer from shoot blight if they are pruned too much, so it is not advisable to prune too much. Camellia usually has several main branches. Cutting off the top of the trunk will promote the lateral buds at the base of each main branch to form lateral branches. After several years of repeated pruning, it can create a short crown appearance.

Pruning of large camellia trees is also important. A high-standard camellia tree should have obvious trunk, clear main branches and regular tree structure.

The pruning steps are as follows:

First, cut off all the sick and dead branches;

Second, cut off all the long branches that grow from the lower part of the trunk;

Third, cut off the long branches that extend upward along the trunk or main branch;

Fourth, determine several reasonable leading branches as the skeleton, and cut off other intersecting and interfering leading branches. Each main branch has two lateral branches, so that the whole branch keeps three-dimensional distribution. If it is defined as narrow crown type, it is important to trim long branches and side branches; If its shape is a short crown, it is important to trim the long branches growing at the top. Keep pruning every year, the tree shape of this camellia will be longer and better.

Question 4: How to prune camellia? As I said before, camellia grows slowly, only leaves twice a year, and rarely in summer, which is not suitable for intensive pruning. When pruning, we should master the following six principles: (1) Cut off diseased dead branches, overgrown branches, cross branches and overlapping branches, and the cutting mouth should be smooth, leaving no residual piles. (2) Leave three for each branch. Keep the main branch on each branch. (3) The branches that are too high should be taken back and trimmed, and new buds will grow at the lower part of the incision, so that the plants will be fuller. (4) After pruning, the sprouted extra buds should be wiped off. Generally, it is advisable to leave two buds at each germination point. (5) According to the cultivation requirements, camellia can be trimmed into different shapes, such as round head, straight tube, short crown or other geometric figures. This kind of shaping method has a large amount of pruning, and the sprouted branches after pruning are strong, which requires multiple pruning to control the tree type. (6) Camellia pruning should be carried out continuously for many years, and the weak direction should be supported and the strong direction should be controlled according to the shape of the tree, so that the plants can develop in a balanced way and achieve the effect of beautiful flowers. Pruning is not only pruning, but also pruning in a broad sense should include measures such as core removal, leaf picking, bud peeling, peeling, leaf cutting and bundling. This is done to adjust the density and orientation of branches and leaves, the height, width and narrowness of plant types. Stripping and binding mainly control the growth of different parts and make collective adjustment. For example, leaves, twigs and buds are dense but not in harmony with other parts, and a part can be directly removed or cut off to make the plant balanced and symmetrical. Local branches or buds are uneven or tend to be steep, so local peeling and tight bunching can be used to control nutrient transportation to adjust and balance nutrient distribution and growth rate of each part. When cutting, picking and bundling, attention should be paid to keeping the stubble flat and appropriate in length so as not to damage other branches, leaves and buds.

Question 5: When should camellia be pruned? How to trim? Before and after flowering, cut off the old branches, make the branches too dense, and try to choose the branches that grow inward.

Question 6: How to manage camellia? When should I trim it? Thank you in advance. Camellia avoid strong light, so be sure to pay attention to the sun when planting. In spring and autumn, we need enough light, but in summer, we must avoid direct sunlight. Camellia will die easily if exposed to strong light for too long. If possible, it is best to transplant it under the shed.

Second, pay attention to the temperature. Camellia is neither cold-resistant nor heat-resistant. Its optimum temperature is 18-25 degrees, so it is required that the ambient temperature should not be too high or too low, otherwise it will affect its growth, especially in winter. The indoor temperature must be above 3 degrees, and frostbite will occur below 0 degrees.

Third, watering matters Camellia likes a humid environment, so we must pay special attention. Not too dry, not too wet, and not too wet when dry. Generally, you can water more in spring, which is beneficial to germination. Water twice in the morning and evening in summer, and it is best to water the leaves when the plants are hot. Autumn and spring are the same, but it is best to water them before and after, and it is best not to water them every time.

Fourth, the main points of fertilization Camellia likes fertilizer, so special attention should be paid to the application of fertilizer during the whole breeding process, such as adding phosphorus and potassium fertilizer to the upper pot, but fertilization is limited and must not be too much. Generally, it only needs to be fertilized about three times within six months after flowering, and once in winter. In order to make the flowers more beautiful, it is better to put more phosphate fertilizer in the fertilizer.

Fifth, the pruning of flower branches is very important. Generally, the branches that affect the tree shape and the weak branches are cut off and arranged into buds. Once the buds are too dense, they should be combed and picked in time after the flowers wither, which can reduce the consumption of nutrients.

Sixth, many people will ignore that camellia will turn over the pot. Actually this is very wrong. Camellia usually turns the pot once every two years, so it needs to be changed into a big pot, which is beneficial to its growth. Pay special attention to the time to turn over the pots, preferably in April. When turning over the pots, be careful not to remove all the old soil, but also add a small amount of base fertilizer to it before proceeding.

Seven, pest control Camellia is easy to get sick. There are two common diseases-black mold and anthracnose. At this time, only 0.5 degree Bordeaux mixture needs to be sprayed, and the pests of camellia are mainly tea-tip moths. At this time, it is enough to cut off the insect tip.

Question 7: How to Prune Camellia To put it bluntly, it is a method to correctly master camellia pruning according to the different flower bud differentiation periods. Actually, this is the key. Camellia can be divided into two types according to the time of flower bud differentiation: (1) summer-autumn differentiation type. Most camellias usually bloom in spring, and their flower buds begin to differentiate in summer and autumn of the previous year. Pruning must be done after flowering. If pruning is carried out in winter and spring, many flower buds will be cut off. When pruning is too late, these unnecessary flower buds will consume a lot of nutrients, thus affecting the quality and quantity of flowering; (2) In the same year, a few camellia varieties bloomed in autumn, such as autumn peony and flower peony, which are well-known varieties in China, and generally bloomed in the middle and late June of 65438+ 10. It does not need a vernalization period (that is, low temperature time) for summer and autumn differentiation, but directly blooms in the same year. The differentiated camellia that bloomed in the autumn of that year, its flower buds were formed and blossomed on the new shoots of that year, and there was no low temperature, so this variety of camellia could be pruned during the dormant period (although this variety of camellia was less).

Question 8: How to prune camellia! ~ ~ What are the skills? Camellia can be trimmed and shaped all year round, which can be divided into spring cutting, summer cutting, autumn cutting and winter cutting. In winter and spring, pruning has a strong ability to sprout tillers, and often more buds will sprout after pruning. Therefore, pruning in winter and spring is suitable for dwarfing, shaping and shrinking trees and restoring tree vigor; Pruning in summer and autumn, the sprouting ability of pruned branches is weak, so it is suitable for pruning internal branches, transverse branches, dead branches and so on. And pruning for tree shaping and improving ventilation and light transmission conditions in plant branches. From the point of view of improving the quality and flower quantity of camellia, the best time for pruning and shaping is after flowering and before the spring shoots sprout. Specifically, tea plums are pruned in March, camellias are pruned in April and Yunnan camellias are pruned in May. Pruning after flower bud formation or before flower bud expansion can not only concentrate nutrition, but also play a role in thinning buds. With fewer buds, flowers can bloom very big. To some extent, this pruning can have the same effect as using gibberellin to promote flowers. So when to trim and reshape depends on the specific purpose of trimming. Emuch/... 711019 is introduced in detail.

Question 9: Pruning methods of camellia There are many varieties of camellia, but most of them grow well without pruning. If pruning is really necessary, internal branches and useless branches should be pruned about 20 days before germination, and those with bad shape can be pruned again. Under the condition of not damaging the trees, it is advisable to knock off the top buds and promote the germination of side buds to control the plant type. Thin fertilizer should be applied to the trees after heavy pruning, mainly nitrogen fertilizer in the early stage, phosphorus and potassium fertilizer should be paid attention to during flower bud differentiation, and potassium dihydrogen phosphate should be sprayed on the leaves in time to keep the pot soil slightly dry, which is beneficial to flower bud differentiation.

Question 10: How to trim Camellia How to trim Camellia How to trim Camellia?

Camellia grows slowly and leaves only twice a year, which is rare in summer and not suitable for intensive pruning. Pruning should master the following six principles:

(1) Cut off diseased dead branches, overgrown branches, cross branches and overlapping branches, and make the cut smooth, leaving no residual piles.

(2) Leave three for each branch. Keep the main branch on each branch.

(3) The branches that are too high should be taken back and trimmed, and new buds will grow at the lower part of the incision, so that the plants will be fuller.

(4) After pruning, the sprouted extra buds should be wiped off. Generally, it is advisable to leave two buds at each germination point.

(5) According to the cultivation requirements, camellia can be trimmed into different shapes, such as round head, straight tube, short crown or other geometric figures. This kind of shaping method has a large amount of pruning, and the sprouted branches after pruning are strong, which requires multiple pruning to control the tree type.

(6) Camellia pruning should be carried out continuously for many years, and the weak direction should be supported and the strong direction should be controlled according to the shape of the tree, so that the plants can develop in a balanced way and achieve the effect of beautiful flowers.

Pruning is not only pruning, but also pruning in a broad sense should include measures such as core removal, leaf picking, bud peeling, peeling, leaf cutting and bundling.
