How to grow guelder rose:
1. Soil: Guelder rose has strong adaptability and can be cultivated in sandy soil, clay soil, and general soil. Seedlings grown in sandy soil have well-developed root systems.
2. Transplanting: Guelder rose is easy to transplant and survive. Carry it out in early spring before bud break, preferably in a semi-shaded environment. After it survives, pay attention to fertilizer and water management.
3. Fertilizing: Guelder rose should be fertilized with light fertilizer applied frequently. If leaves turn yellow, spray the leaves with a 1/1000 ferrous sulfate solution. Fertilize once after flowering.
4. Pruning: The main branches of guelder rose easily sprout water shoots that disrupt the tree shape. After flowering, prune appropriately. In summer, cut off the tips of water shoots to tidy the overall shape.
5. Pests and diseases: The leaves of guelder rose have more hairs and are generally not easily harmed by pests and diseases, but during the plum rain season it usually needs some Bordeaux mixture sprayed for prevention and control.
How to propagate guelder rose:
1. Sowing: Guelder rose is commonly propagated by seeds. Collect seeds in November, pile them for after-ripening, wash the seeds, stratify them at low temperature until sowing the following spring, cover with soil slightly thick, and then cover with grass on top. In June of that year, some will germinate and emerge. At this time, remove the grass and provide shade. Keep them in the bed for 2 years, then they can be divided and replanted in another bed. After 4-5 years, they can be transplanted for garden landscaping.
2. Grafting: Graft guelder rose in early March (before buds sprout). Take a branch from a mother tree that can flower, cut a section about 5 cm long as the scion, and it is ideal to keep the terminal bud. Generally use the high grafting method. After grafting, place it in a shaded area. After the scion buds produce leaves, place it directly in sunlight. After it survives, it can bloom in the first year.
Alright, that is all for the introduction to guelder rose planting methods. Everyone should understand now.
How to grow guelder rose, guelder rose cultivation methods and precautions / Sufficient sunlight
Guelder rose is a famous flower unique to China, and it is also the city flower of Yangzhou City, Jiangsu Province. It has the reputation of “only one flower in Yangzhou, with no equal in the four seas.” Many people in the Yangzhou area grow it, but there are many points to note when growing it. How do you grow guelder rose? What are the cultivation methods and precautions for guelder rose? Below, the editor will take everyone through an introduction.
I. How to grow guelder rose
Regarding how to grow guelder rose, first we need to understand its growth habits. Guelder rose is a light-loving plant, so during cultivation it needs to maintain sufficient light. In addition, watering, fertilizing, and other aspects also need attention. For details, please continue reading below in the cultivation methods and precautions for guelder rose.
II. Cultivation methods and precautions for guelder rose
1. Soil selection
When growing guelder rose, the first step is to choose soil. This is the step that lays a good foundation, so it is very important. Generally, you can choose sandy soil with relatively high looseness. This kind of soil has good drainage and air permeability and can allow guelder rose to absorb nutrients better.
2. Fertilization management
During the growth process of guelder rose, the demand for fertilizer is very high. This is one of the main nutrients in its growth process. Basically, it needs to be fertilized once a month, which can make guelder rose grow more robust. From this, we can see the importance of fertilization in the cultivation methods and precautions for guelder rose.
3. Watering management
Guelder rose likes a warm and humid environment, so during cultivation it must be watered frequently, but the amount of watering should be noted. When watering, make sure to water thoroughly, but do not water too much, otherwise water accumulation can easily cause root rot.
4. Light management
In the cultivation methods and precautions for guelder rose, light is a very important point. Guelder rose is a light-loving plant, so during cultivation it must maintain sufficient light. However, when sunlight is too strong, shade is still needed, especially in summer, when shade is still required.
5. Pest and disease control
During the cultivation of guelder rose, if care is improper, pest and disease problems are very likely to occur. Such problems are extremely harmful to guelder rose. If not dealt with in time, they can easily cause the plant to wither and die.

Cultivation methods and precautions for Tianmu guelder rose Introduction to Tianmu guelder rose
Tianmu guelder rose is a plant of the genus Viburnum in the Caprifoliaceae family. Its young branches, leaves, and fruits can be used as medicine. Its branches and leaves can promote meridians and collaterals, detoxify, and relieve itching. The branches can be used for rheumatoid arthritis, soreness and pain in the waist and legs, and traumatic injuries. The leaves can be used externally to treat sores and boils, tinea, and itchy skin. The fruit of the chicken tree strip can relieve cough and is often used for acute and chronic bronchitis and cough. The chicken tree strip mainly grows on hillsides, forest edges, and mixed woods. It is distributed in Liaoning, Jilin, Heilongjiang, Inner Mongolia, Shandong, Hebei, Hubei, Sichuan, Zhejiang, and other places in China.
The tree form of Tianmu guelder rose is elegant, the leaf shape is beautiful, the flowers bloom like snow, and the fruits are red like cinnabar. It is suitable for planting around buildings and at the edges of lawns, and can also be planted alone, in groups, or in patches by roadsides and beside rockeries. The branches, leaves, and fruits can all be used as medicine. The compound umbel inflorescence of Tianmu guelder rose is very special. The marginal flowers (the ring of flowers around the outside) are white and very large, very beautiful but unable to set fruit. The central flowers (the small flowers in the center) are unremarkable in appearance but can produce abundant red fruits. The two types of flowers make it possible to view flowers in spring and fruits in autumn, and it is widely used in gardens.
Morphological characteristics of Tianmu guelder rose
Tianmu guelder rose is a deciduous shrub, 2-3 m tall. Young branches, petioles, and peduncles are all hairless. The underside of the leaves has clustered tufts of hair only in the leaf vein axils, or sometimes there are also a few long appressed hairs on the veins.
The bark of Tianmu guelder rose is dark grayish brown, with longitudinal stripes and corky layers; the young branches are brown to reddish brown, with obvious ridges. The leaves are dark green, simple, and opposite; ovate to broadly ovate, 6-12 cm long and 5-10 cm wide, usually shallowly 3-lobed, with a rounded or truncate base, bearing palmately 3-veined veins, the lobes slightly spreading outward, the middle lobe longer than the lateral lobes, the apex gradually pointed or abruptly pointed, the margin with irregular large teeth, the upper surface yellow-green and hairless, the lower surface light green, with downy hair in the vein axils; the petiole is stout, hairless, with glandular dots near the apex.
The umbellate cyme of Tianmu guelder rose is terminal, dense and many-flowered, composed of 6-8 small corymbs, 8-10 cm in diameter. The fertile flowers are in the center, and there are sterile ray flowers on the outside. The common peduncle is stout, 2-5 cm long; the corolla is cup-shaped, spreading radially, milky white, 5-lobed, 5 mm in diameter; the anthers are purple; the sterile flowers are white, 1.5-2.5 cm in diameter, deeply 5-lobed. The drupe is spherical, 8 mm in diameter, bright red, with an unpleasant odor and lasting a long time without falling. The seeds are round and flat.
The flowering period of Tianmu guelder rose is May-June, and the fruiting period is August-September.
Ecological habits of Tianmu guelder rose
Tianmu guelder rose likes light and is also shade-tolerant; it is cold-resistant and mostly grows in thickets with cool summers, moisture, and much fog; it has no strict requirements for soil and can grow in slightly acidic and neutral soils; when introduced, it has obvious requirements for relative air humidity and semi-shaded conditions. Seedlings must be shaded, while adult seedlings planted at forest edges grow and develop normally.
Cultivation techniques for Tianmu guelder rose Humidity management
It likes a slightly humid to dry climate environment.
Temperature management
Cold-resistant. It has difficulty getting through summer during high-temperature periods and cannot endure stuffiness, otherwise it will enter a semi-dormant state and growth will be hindered. The most suitable growth temperature is 15-30°C.
Light management
It likes a semi-shaded environment, but after being kept indoors for a period of time (about two months), it should be moved outdoors to a shaded place for a period of time (about one month), and alternated in this way. When kept indoors, place it in a place with bright light as much as possible, such as a well-lit living room, bedroom, study, and other places, but avoid direct sunlight shining on it. In early spring, late autumn, and winter, because the temperature is not very high and the sunlight is not strong, you can give it direct sunlight in the morning and evening to help it carry out photosynthesis and grow healthily.
Fertilizer and water management
It likes the potting soil to be dry or slightly moist, but its root system fears waterlogging. If water accumulates in the flowerpot, or if it is watered and fertilized too frequently, root rot is likely to occur. The principle for fertilizing and watering it is "alternate dry and wet, dry means thoroughly dry, do not water if not dry, and water thoroughly when watering":
Spring and autumn
These two seasons are its peak growth seasons. Fertilizer and water management follows the cycle of "Hua Bao" - clear water - "Hua Bao" - clear water, with intervals of about: 1-4 days for outdoor cultivation, shorter intervals on sunny days or during high temperatures, and longer intervals or no watering on rainy days or during low temperatures; 3-6 days for indoor cultivation, shorter intervals on sunny days or during high temperatures, and longer intervals or no watering on rainy days or during low temperatures.
Summer
During the high-temperature period in summer, it grows slowly and has little demand for fertilizer and water, so fertilizer and water need to be moderately controlled. Fertilizer and water management follows the cycle of "Hua Bao" - clear water - clear water - "Hua Bao" - clear water - clear water, with intervals of about: 1-3 days for outdoor cultivation, shorter intervals on sunny days or during high temperatures, and longer intervals or no watering on rainy days or during low temperatures; 3-5 days for indoor cultivation, shorter intervals on sunny days or during high temperatures, and longer intervals or no watering on rainy days or during low temperatures. Try to arrange watering time in the morning or evening when the temperature is lower.
Winter
In winter, the plant grows slowly, and the main task is to control fertilizer and water well. Fertilizer and water management follows the cycle of "Hua Bao" - clear water - clear water - "Hua Bao" - clear water - clear water, with intervals of about 4-8 days, shorter intervals on sunny days or during high temperatures, and longer intervals or no watering on rainy days or during low temperatures. Try to arrange watering time at noon on sunny days when the temperature is higher.
Pruning
In winter, after the plant enters dormancy or semi-dormancy, cut off thin and weak, pest- and disease-affected, dead, and overly dense branches.
Rotating the pot
As long as it is cared for properly, it will grow very quickly. When it grows to a certain size (about two to three years), consider giving it a larger pot so that it can continue to grow vigorously. For the potting soil and component ratio used for repotting, one of the following can be chosen:
Vegetable garden soil
Furnace slag = 3:1; or garden soil: medium-coarse river sand: sawdust (mushroom residue) = 4:1:2; or one of paddy soil, pond mud, or leaf mold.
Removing from the pot
Place the flower to be repotted on the ground. First, lightly pat the sides of the pot with your palm to make the root system vibrate and separate from the pot wall. Turn the flowerpot upside down and place it on your left hand. Gently clamp the plant between the index finger and middle finger of your left hand, with your wrist and fingertips against the rim of the pot. Pat the bottom of the pot with your right hand, then use your thumb to push the root soil downward from the bottom hole so the plant comes out. After it comes out, gently pat the potting soil with both palms to let excess soil fall off.
Flowerpot preparation
Choose a flowerpot of appropriate size. Cover the bottom hole of the pot with two pieces of tile or thin foam pieces. This should both ensure that the potting soil is not washed out by water and allow excess water to flow out in time. On top of the tile or foam, place a layer of ceramsite or crushed red bricks as a drainage layer, about 2-3 cm thick. On the drainage layer, place organic fertilizer, about 1-3 cm thick. On top of the fertilizer, place a thin layer of substrate, about 2 cm thick, to separate the root system from the fertilizer. Finally, put the plant in, fill with nutrient soil, and leave about 2-3 cm from the pot rim.
Related questions on cultivation methods of Tianmu guelder rose
What should be done if Tianmu guelder rose has few flowers and sparse leaves?
The flowers, leaves, fruits, and tree form of Tianmu guelder rose are extremely beautiful, combining flower viewing, leaf viewing, and fruit viewing in one. If care and management are improper, it will cause few flowers and sparse leaves, greatly reducing its ornamental value. To make Tianmu guelder rose have abundant flowers and lush leaves, you must do the following:
① Choose fertile, well-drained sandy loam soil.
② Apply sufficient base fertilizer when planting. After that, apply decomposed organic fertilizer to the soil around the roots every year after autumn, and apply 1 light fertilizer each before and after flowering.
③ After autumn and before bringing it indoors each year, prune off overly dense branches, dead branches, and pest- and disease-affected branches, and shorten weak long branches; before bud break the next year, cut off the previous year's fruit clusters.
④ Do not water too much. In rainy seasons, drain water and prevent waterlogging, and promptly pour out accumulated water in the pot.
Propagation methods of Tianmu guelder rose
Tianmu guelder rose can be propagated by division or sowing.
One,Cuttage
Softwood cuttings are often taken in late spring and early autumn using current-year branches, or hardwood cuttings are taken in early spring using last year's branches.
Cutting substrate
This refers to materials such as nutrient soil, river sand, or peat soil used for cuttings. For home cuttings, due to limited conditions, it is difficult to obtain an ideal cutting substrate. It is recommended to use a already prepared and sterilized cutting substrate; medium-coarse river sand can also be used, but it should be rinsed several times with clean water before use. Do not use sea sand or river sand from saline-alkali areas; they are not suitable for the growth of flowering plants.
Selection of cutting branches
When carrying out softwood cuttings, during late spring to early autumn when the plant grows vigorously, select robust current-year branches as cuttings. After cutting the branches off, select the sturdy parts and cut them into sections 5-15 cm long, with each section bearing more than 3 leaf nodes. When cutting the cuttings, note that the upper cut should be made flat about 1 cm above the topmost leaf node, and the lower cut should be made diagonally about 0.5 cm below the bottommost leaf node. Both upper and lower cuts should be smooth (the knife should be sharp). When carrying out hardwood cuttings, after the temperature rises in early spring, select robust branches from the previous year as cuttings. Each cutting usually retains 3-4 nodes, and the cutting method is the same as for softwood cuttings.
Management after cutting
Temperature
The optimal temperature for cutting rooting is 20°C-30°C. Below 20°C, cuttings root with difficulty and slowly; above 30°C, the upper and lower cuts of the cuttings are easily infected by pathogens and rot, and the higher the temperature, the greater the proportion of rot. When low temperatures occur after cutting, the main measure for keeping warm is to wrap the flowerpot or container used for cuttings with plastic film; when the temperature is too high after cutting, the main cooling measure is to shade the cuttings, blocking 50-80% of sunlight, and at the same time spray the cuttings 3-5 times a day. On sunny days with higher temperatures, spray more often; on rainy days with lower temperatures and higher humidity, spray less often or not at all.
Humidity
After cutting, the relative air humidity must be maintained at 75-85%. The basic requirement for cutting rooting is that before the cuttings root, it must be ensured that the cuttings remain fresh and tender and can carry out photosynthesis to produce rooting substances. However, cuttings that have not rooted cannot absorb enough water to maintain their internal water balance. Therefore, spraying must be used to reduce water evaporation from the cuttings: under shaded conditions, spray the cuttings 3-5 times a day. On sunny days with higher temperatures, spray more often; on rainy days with lower temperatures, spray less often or not at all. However, excessive spraying makes cuttings easily infected by pathogens and rot, because many kinds of pathogens exist in water.
Light
Cuttage propagation cannot do without sunlight, because the cuttings still need to continue photosynthesis to produce nutrients and rooting substances to supply their rooting needs. However, the stronger the light, the higher the temperature inside the cuttings, the stronger the transpiration of the cuttings, and the more water consumed, which is not conducive to the survival of the cuttings. Therefore, after cutting, 50-80% of sunlight must be blocked. After the root system grows out, gradually remove the shade net: on sunny days, remove the shade net at 4:00 p.m. every day, and cover it again before 9:00 a.m. the next day.
Two,Layering propagation
Select robust branches. From about 15-30 cm below the top shoot, peel off a ring of bark. The width of the wound after peeling should be about 1 cm, and the depth should be just enough to peel off the outer bark. Cut a piece of plastic film 10-20 cm long and 5-8 cm wide, place some moistened garden soil on it, and wrap the girdled part as if wrapping a wound. Tie the upper and lower ends of the film tightly, with the middle bulging. Roots form in about four to six weeks. After rooting, cut off the branch together with the root system, and it becomes a new plant.
Potting or transplanting: When potting small seedlings or repotting large plants that have been grown for several years, first place coarse-grained substrate 2-3 cm thick at the bottom of the pot as a drainage layer, sprinkle a layer of fully decomposed organic fertilizer on top as base fertilizer, about 1-2 cm thick, then cover with a thin layer of substrate about 1-2 cm thick, and then place the plant in, so as to separate the fertilizer from the root system and avoid burning the roots.
For the substrate used for potting, one of the following can be chosen: vegetable garden soil: furnace slag = 3:1; or garden soil: medium-coarse river sand: sawdust (mushroom residue) = 4:1:2; or one of paddy soil, pond mud, or leaf mold. After potting, water once thoroughly and place it in a shaded environment for one week of care. When transplanting small seedlings, first dig the planting hole, spread a layer of organic fertilizer at the bottom of the planting hole as bottom fertilizer (base fertilizer), about 4-6 cm thick, then cover with a layer of soil and place the seedling in, so as to separate the fertilizer from the root system and avoid burning the roots. After placing the seedling in, backfill the soil, cover the root system, and press the soil firmly with your feet, then water once thoroughly.
Rapid propagation technique
1. Material collection
Select 1-year-old robust, semi-lignified, straight branches with short bud spacing as material. This kind of branch is grayish green, flexible and elastic. When collecting material, be sure to include a section of 3-5 cm 2-year-old old branch. After collection, immediately immerse the lower part of the material in a bucket to avoid water loss during transport.
2. Material preparation
The detached material is 15-20 cm long and 0.5-0.6 cm thick. The upper end of the material is a flat cut, 2.5-3 cm from the terminal bud; at 0.5 cm diagonally below the bottom bud, cut into a horseshoe-shaped cut, and the cut should be smooth. Remove all lower leaves, leaving only the top 2, and cut each in half to reduce transpiration.
3. Root-promoting treatment of material
After the detached material is cut, immediately immerse the lower cut in a plastic container holding a 500 PPM ATP No. 1 rooting powder solution, with an immersion depth of 4 cm and a treatment time of 30 min. After removal, carry out rapid propagation immediately.
4. Rapid propagation
First use a wooden stick 0.8 cm thick to make holes, with a depth of 3 cm, a plant and row spacing of 5 cm x 5 cm, 400 plants per square meter, and a rapid propagation depth of 3 cm.
5. Seedbed management
12 d after propagation, callus tissue can basically cover the cut; after 17 d, some take root; after 24 d, 90% of the materials have rooted. After about 7-10 days of hardening, they can be transplanted to the field.
