How to trim the red leaf heather, which shapes can be trimmed / six kinds can be trimmed.

We know that pruning is a very necessary and critical step in the cultivation of Photinia chinensis, because it can maintain the beauty of the plant and promote growth, so how to prune it? Which shapes can be trimmed by Photinia rugosa? Let's find out the answer.

How to prune Photinia rugosa

1. When will the heather be pruned?

Photinia rubra will sprout a new bud in March, June and September, so the big pruning generally chooses these three times to cut off the excess branches, which is conducive to the growth of new buds. In addition to these time periods, if diseased leaves are found or pots changed, they can also be trimmed.

2. Where is the pruning

The position of the cut is generally chosen at more than 10 cm from the bud to avoid being too close to affect the growth of new buds.

Note: sharp knives should be used during construction, and the cut should be properly tilted, trimming should not be chosen in winter, so as to avoid the low temperature affecting the recovery of Photinia rubra.

Which shapes can be trimmed by Photinia rugosa

1. Cube modeling

How to trim the red leaf heather at this time? Choose the size of the cube you want, and then cut the top and sides of Photinia chinensis into a neat square. When building, start with the plants with strong growth and luxuriant leaves, cut the top flat, and then re-cut the surrounding side branches, leaving the appropriate length, the new branches will gradually grow into the required shape after germination.

2. Cylindrical modeling

Select the sturdy plants with high height, need to pick the heart at the initial stage of growth, and then trim the branches and leaves into a cylinder from the upper to the lower, and in the subsequent growth process, the branchlets will gradually grow out, and then properly reshape at this time.

3. Arbor type

Photinia rubra is both a tree and a shrub. If you want to prune it into a tree type, you need reasonable fertilization and watering in one year to promote the growth of the plant height, and cut off the lower part of the lateral branches in the second year. When the official reaches 1.5 meters high, top the main shoot, wait until the main shoot develops to 30-40 cm thick, and top for the second time.

4. Short spherical shape

When you want a low spherical shape, how to trim the red leaf heather? The answer is that topping is needed at the seedling stage, and when multiple lateral branches are removed, the second topping is carried out. If the branches on the crown are growing vigorously and need to be rebuilt, the lateral branches are trimmed lightly, and then the long branches are removed to make the whole crown closer to the middle, and then slightly reshape it into a ball.

5. High dry spherical shape

Using Photinia chinensis seedlings as rootstock, under the condition of ensuring sufficient backbone height, the crown was reshaped and constructed, and then 6 buds were grafted on the rootstock by bud grafting method according to the distribution of crown branches. after that, pay attention to real-time sprouting to promote bud germination, and then build it with the method of dwarf ball.

6. Hedge modeling

First, the top is cut flat, the height can meet the requirements, the cross section can be rectangular or trapezoidal, and then the lateral branches can be cut vertically with the thickness to meet the requirements to ensure that the construction of the surface is neat and flat.

How to trim the red leaf heather? Pruning methods of Photinia rubra

[FAQ] how to prune Photinia rubra?

Photinia przewalskii has high ornamental value and is often used as street trees or hedges. Pruning and landscaping is an important way to make heather more ornamental. The pruning methods of Photinia rubra are introduced as follows:

First, the isolated tree type

In the first year, the treatment of flood fertilizer was added at the seedling stage to promote the development of seedling height, and in the second year, the lower side branches of the plant were properly removed and continued to be treated with flood fertilizer. From the end of February to the beginning of March, the lower side branches were removed according to the requirement of the backbone height of about 1.5 meters, and the upper main shoot was topped to form a crown. It is generally required to have 3 or 4 side branches, but after topping for the first time, it is still less than 3 to 4 side branches. After the development of the main shoot is 30cm to 40cm, the second topping is carried out to divide the lateral branches again, and through continuous cultivation, the specification of the tree type of isolated trees for engineering can be reached.

Second, short spherical shape

When the seedling height of Photinia rubra is about 40 cm, topping is carried out to promote the division of multiple lateral branches (at least 3-4). If the number of lateral branches is still less than 3-4 after the first topping, the second topping is carried out as appropriate. In the future, due to the development and prosperity of the upper branches of the crown, it is necessary to cut heavily, and the side branches should be gently cut to remove the long branches in real time, so that the whole crown is close to the center and gradually "huddled together." after light cutting and shaping, it becomes a ball.

Third, Gao Gan spherical shape

Usually, the high-dry spherical shape of Photinia chinensis can be done in two ways.

1. Method 1: in the first year, the treatment of water and fertilizer was strengthened to promote the development of seedling height, and in the second year, the local side branches of the lower part of the plant were properly trimmed, and flood fertilizer was added continuously. From the end of February to the beginning of March in the third year, all the lower side branches were thinned and lost according to the requirements of the backbone height of about 1.2 meters, and all the branches above 1.2 meters were preserved, and the main shoots were topped to promote side branches, which could be trimmed according to the method of short spherical shape in the future.

two。 Method 2: choose Photinia seedlings as rootstock, under the condition of sufficient backbone height, trim the crown, according to the scattered part of crown branches, according to the requirement of crown roundness, grafting 6 buds on the rootstock by bud grafting, pay attention to real-time wiping buds after grafting, promote bud germination, in the future, using dwarf ball shaping method for pruning, it can be cultivated into high-dry red leaf heather balls, because the bud grafting is easy to survive. Using this method to cultivate high dry ball seedlings of Photinia chinensis is not only labor-saving but also easy to operate, so it is worth carrying out vigorously.

Fourth, cylindrical modeling

Select the plant according to the height to be modeled (that is, the height of the column is required). When the height of the selected plant reaches the high requirement of the column, pick the backbone (that is, top), and then trim the branches and leaves into a cylinder from the upper to the lower part of the plant according to the expected pruning line. after the branchlets grow, they will be adjusted gradually to cultivate the cylindrical tree directly, and when the height of the selected plant does not meet the high requirements of the column, it is necessary to strengthen the treatment of water and fertilizer. The central branch of the plant is preserved, the surrounding branches are cut short and round, so that the plant has a sense of "soaring into the sky", and the plant is cultivated. When the height of the plant reaches the requirements, the backbone is topped, and the branches around the plant are continuously cut short and round. After gradual pruning, a cylindrical tree can be cultivated.

5. Hedge modeling

Photinia hedgerows can be divided into green hedge and distance hedge.

1. Hedgerow shape: the top of the plant is re-flat cut according to the height of the hedge, the cross section can be so flat rectangular, can also be trapezoidal, the side branches can be cut vertically according to the thickness requirements of the green hedge wall, and its trimming surface is required to be "flat and even". In the future, gradually precision pruning can be formed.

two。 Distance hedge: there are differences in the length of the hedge, which is about 1 to 1.5 meters, and each section is separated by a certain interval, and the modeling method is the same as that of the green fence.

VI. Cube modeling

The cube tree type means that the top section and the surrounding section of the plant are uniform square. According to the requirements of the size of the cube, the Photinia plant with strong and luxuriant branches and leaves is selected. First, the top of the plant is re-cut and flattened, and then the surrounding side branches are re-cut in proper length to promote the emergence of new branches. After the new branches germinate, they are cultivated and then gradually trimmed into a "square" plane.

[editor's conclusion] after pruning and landscaping, Photinia chinensis has a variety of shapes, good landscape effect and more ornamental value. The pruning method of Photinia rubra is introduced in the above, and I hope it will be helpful to you!

Pruning techniques of Photinia rubra

Red leaf Photinia is a kind of green plant, common varieties are red Robin, red lips and so on, usually used as street trees or hedges, need to be trimmed landscape, after pruning can be a variety of shapes, the landscape effect is beautiful, and red leaf Photinia pruning is skillful, let's take a look at red leaf Photinia pruning method!

Growth habits of Photinia rugosa

Photinia likes warm, humid and sunny environment, has strong cold tolerance, can withstand the lowest temperature-18 ℃, likes strong light, and has strong shade tolerance. It is suitable for all kinds of medium fertilizer soil, barren soil, salt-alkali resistance and drought tolerance, not water and moisture resistance, fast growth rate, strong sprouting ability, pruning resistance, easy to transplant and shape.

Pruning skills of Photinia rubra

1. Pruning time: Photinia pruning has three main months of birth in March, June and September, so pruning Photinia should leave the vacant places in the middle of these three months, and the extra branches will be trimmed off. In this way, its crown width will become more and more round, more and more refined.

2. Pruning position: when pruning the branches of Photinia rubra, do not get too close to the bud, so as to avoid the growth of new sound buds.

3, crown width refinement: in general, there will always be a small number of hanging branches below it, and these branches will be beautiful in sound crown, so it is necessary to prune these branches without sound crowns. In this way, the crown width of Photinia rubra is round and tight, and a fine crown width of Photinia rubra is presented in this way!

Pruning methods of Photinia rubra

1. Isolated tree type: in the first year, flood fertilizer was added to the seedling stage to promote the development of seedling height, and in the second year, local lateral branches in the lower part of the plant were properly trimmed and continued to be treated with flood fertilizer. From the end of February to the beginning of March in the third year, according to the requirements of the backbone height of about 1.5 meters, the lower side branches were removed, and the upper main shoots were topped to promote the side branches to form a crown. 3 or 4 side branches were generally required, after the first topping. If the number of lateral branches is still less than 3 to 4, the second topping will be carried out after the development of the main shoot of 30 to 40 centimeters, and the lateral branches will be divided again. Through continuous cultivation, the specification for the type of isolated trees for engineering can be reached.

2. Low spherical shape: Photinia chinensis seedlings are topped when the seedling height is about 40 cm, promoting the division of multiple lateral branches (at least 3-4). If there are still less than 3-4 lateral branches after the first topping, the second topping is carried out as appropriate. In the future, due to the development and prosperity of the upper branches of the crown, it is necessary to cut heavily, and the side branches should be gently cut to remove the long branches in real time, so that the whole crown is close to the center and gradually "huddled together." after light cutting and shaping, it becomes a ball.

3. High-dry spherical shape: usually the high-dry spherical shape of Photinia rubra can be done in two ways.

① method 1: strengthen water and fertilizer management to promote seedling height development in the first year, properly remove local lateral branches in the lower part of the plant in the second year, and continue to add flood fertilizer treatment. In the third year, from the end of February to the beginning of March, according to the requirements of the backbone height of about 1.2m, all the lower lateral branches will be lost, all the branches above 1.2m will be preserved, and the main shoots will be topped to promote lateral branches, and the future will be trimmed according to the method of short spherical shape.

② method 2: select large Photinia seedlings as rootstocks, under the condition of sufficient backbone height, trim the crown, according to the scattered parts of the crown branches, according to the requirements of the crown roundness, use the bud grafting method to graft 6 buds on the rootstock, pay attention to real-time sprouting after grafting, promote bud germination, and use the dwarf ball shape method for pruning, which can be cultivated into high-stem red leaf heather balls. As the bud grafting is easy to survive, using this method to cultivate high-dry ball seedlings of Photinia chinensis is not only labor-saving but also easy to operate, so it is worth vigorously promoting.

4. Cylindrical modeling: the plant is selected according to the height of the shape (that is, the height of the cylinder is required). When the height of the selected plant reaches the height of the column, the backbone is peeled (that is, topped), and then according to the expected pruning line, the branches and leaves are trimmed into a cylinder from the upper to the lower part of the plant, and then gradually adjusted to cultivate the cylindrical tree directly when the height of the selected plant does not meet the high requirements of the column. To enhance the treatment of water and fertilizer, the central vertical branches of the plant should be preserved, and the surrounding branches should be cut short and round, so that the plant has a sense of "soaring into the sky". When the height of the plant reaches the requirements, the backbone is topped, and the branches around the plant are continuously cut short and round, and a cylindrical tree can be cultivated after gradual pruning and treatment.

5. Hedge modeling: Photinia hedgerows can be divided into hedges and distance hedges.

① hedgerow shape: the top of the plant is re-flat cut according to the height of the hedge, its cross section can be so flat rectangular, can also be trapezoidal, the side branches can be cut vertically according to the thickness requirements of the green hedge wall, and its trimming surface is required to be "flat and even". In the future, gradually precision pruning can be formed.

② distance hedge: requires that the length of the hedge is different, usually 1 to 1.5 meters for a section, each section must be separated by a certain interval, the modeling method is basically the same as the green hedge.

6. Cube shape: the cube tree, that is, the top section and the surrounding section of the plant are uniform square, according to the size requirements of the cube, choose to develop strong, luxuriant red leaf Photinia plant, first re-cut the top of the plant, and then re-cut the appropriate length of the surrounding side branches to promote the development of new branches. after the new branches germinated, they were cultivated and then gradually trimmed into a "square" plane.
