How to grow Chinese roses? Potted cultivation methods and precautions
Chinese roses are the main ornamental flowers of spring, with a long flowering period, high ornamental value, and low price. They are loved by gardens everywhere and can be used for garden flower beds, flower borders, and courtyard cut flowers, and can be made into Chinese rose bonsai. Today, the editor will introduce to you how to grow potted Chinese roses!
How to make Chinese rose bonsai
1. Collecting rootstocks: Every spring, go to hillsides and ditches to dig up wild rose rootstocks with peculiar shapes and naturally tapered tips. After the rootstocks are collected, cut the roots and trunks into place as much as possible, and plant them in plain sandy soil mixed with a little sawdust. Either pot planting or ground planting is fine. Cover the whole rootstock with a plastic bag, and after new buds grow 3-5 cm, choose a cloudy and rainy day to remove the plastic bag. Then spray water on the stems and leaves every morning and evening to ensure survival. Fertilization can begin in August, once every half month, preferably with cake fertilizer water. For those whose branches transition naturally, pruning should be carried out in the second spring and management strengthened. When the new branches of that year grow to a certain thickness, grafting can begin. A few that need trunk thickening can continue to be grown on.
2. Grafting: For Chinese rose bonsai grafting, bud grafting is better. It is characterized by simple operation and a long grafting period. Bud grafting can be done from May to September, with a high survival rate. For those that fail to survive grafting, grafting can be repeated at the original site. You can choose the color and variety of Chinese roses to graft according to personal preference. Chinese rose grafting is not difficult, but to achieve a relatively high survival rate, three steps must be mastered.
① Selecting buds: Grafting buds must be taken from healthy branches, and the best time is when they are about to begin sprouting. It is best to cut off the flowers, apply fertilizer, and grow them on for a week, then take buds for grafting when the buds begin to swell.
② Taking buds: For common Chinese roses, use the bark-peeling bud-taking method. Miniature Chinese rose branches are thin, and it is not easy to take buds by the traditional method. First cut the branch from which buds are to be taken into lengths of nearly 2 cm, make slanted cuts from the middle section of the back of the bud toward both ends, then peel the bark from the lower end of the bud, slowly separating the bark from the xylem. Be sure to protect the vascular bundles inside the bud piece. After the bud is removed, according to the height of the rootstock cut, trim both ends of the bud piece flat, gently place it into the rootstock cut, and press it closely against the rootstock xylem. Wrap it tightly with plastic strips, exposing the bud eye.
③ Moisture retention: After grafting and wrapping are completed, if conditions permit, the grafted Chinese rose bonsai can be placed in a plastic greenhouse for care. You can also use the method of covering a single branch with a plastic bag. In this way, it is fine to place it directly in the natural environment for care. After 7-10 days, the plastic covering can be removed and the binding loosened, and supplementary grafting can be done according to survival conditions.
Daily care of potted Chinese roses
1. Light: If you want Chinese roses to bloom continuously, they need long hours of light. Only under full-sun conditions can Chinese roses grow robustly. For potted Chinese roses, aside from needing appropriate shading during high summer temperatures, they can receive full-day light at other times.
2. Watering: Chinese roses prefer a moist and warm environment, but they can also tolerate a certain degree of drought. Usually, water according to the principle of watering thoroughly after the soil dries out. In summer, watering is best done in the morning, while in winter it should be done at noon when the temperature is higher. In addition, potted Chinese roses are not tolerant of high temperatures. When the ambient temperature is high, spraying water can be used to lower the temperature, so as to avoid scorched leaves.
3. Fertilizing: Chinese roses like fertilizer. To ensure flowers can be seen throughout the flowering period, fertilizer water must be applied continuously. In spring, when the plant sprouts new buds, some decomposed cake fertilizer water, bean dregs fertilizer, etc. can be applied. When entering the flowering period and the flower buds gradually grow, apply one more round of diluted fertilizer water. After that, during the flowering period, additional fertilizer water should be applied monthly according to the plant's growth condition and in appropriate amounts, to promptly replenish the nutrients consumed during flowering.
4. Repotting: Chinese roses grow relatively quickly, so nutrients are consumed quickly as well. Every year in spring, the soil and pot should be changed. When changing the soil, add an appropriate amount of organic fertilizer to the potting soil as base fertilizer, to provide the nutrients needed during the growing period.
How should potted Chinese roses be pruned?
How should potted Chinese roses be pruned? The key points to note when pruning Chinese roses are: remove buds before flowering, cut back branches after flowering. Next, the editor will introduce to you how potted Chinese roses should be pruned!
1. Removing buds before flowering: Potted Chinese roses should not keep too many buds. At the beginning, keep 2-3 buds on each branch. When the new buds grow to 3-4 cm, generally keep one flower bud on each branch. Strong branches can also keep 1-2 more buds, so that nutrients are concentrated and the flowers of this flush bloom large and bright. For the whole pot of Chinese roses, only 4-6 flower buds can be kept, and they must be evenly distributed. All other new buds should be removed.
2. Cutting back branches after flowering: After each flush of flowers finishes, promptly cut the flowering branch back to 3-5 leaves from the base. Note that the cutting point should be about 1 cm above an outward-growing leaf bud. At the same time, also cut off diseased branches, dead branches, side branches, and inward-growing branches, so that nutrients are concentrated and strong new branches are promoted. In this way, the plant shape of potted Chinese roses will be compact, and flowering will also be concentrated.
How should potted Chinese roses overwinter?
Chinese roses are a common variety for home flower cultivation. They have relatively strong cold resistance, so in the south they can generally overwinter outdoors in open ground. However, in the north, cold-proof measures should be taken to ensure the plant overwinters safely; otherwise the branches may freeze and be damaged, or even the whole plant may freeze to death. Next, let us continue to see how potted Chinese roses should overwinter!
1. For overwintering Chinese roses, they can be stored through winter in a cold room to make them dormant, so that they develop robustly in the coming spring. Before being brought indoors, prune first, clean the pot surface, and spray with limewater to eliminate insects and prevent disease. Bring them indoors before the potting soil freezes solid. During winter storage, water should be given to prevent wind drying. A room temperature of about 0°C is safest. When it is too cold, seal them tightly with soil. When early spring gradually warms, open them for ventilation to prevent yellow buds from appearing and affecting normal development.
2. They can be kept through winter in a warm room. After pruning, place them outdoors to freeze for a period first, bring them indoors at the end of November, first place them in a low-temperature place to thaw slowly, then move them to a place around 10°C and wait for them to sprout. Then place them indoors in a spot with ample sunlight, requiring more than 4 hours of direct light per day and a temperature of about 20°C. Water lightly, loosen the soil, and on sunny days at noon they can be placed outdoors in a wind-sheltered, sunny spot to grow. When new buds unfold leaves and develop into branches, water and fertilize appropriately, and they can bloom around the Spring Festival.
3. To help Chinese roses overwinter well, applying an appropriate amount of flower fertilizer is also one method. The timing of pruning branches must be mastered. Generally speaking, it is best not to let the plant have tender branches in winter, because tender branches cannot resist cold in winter.
4. Put fruit peels and vegetable leaves into containers such as small buckets and pots, seal the openings tightly with mud, and compost them into humus soil, which can then be applied as a topdressing flower fertilizer. Miscellaneous bones and meat from the family dining table, fish scales, and eggshells are very good base fertilizers for potted flowers. If they are further soaked and fermented, they become a flower fertilizer rich in phosphorus.
How to grow Chinese roses? Potted cultivation methods and precautions for Chinese roses
Chinese rose is called the king of flowers, also known as “Yueyuehong”, and belongs to the Rosaceae family. It is an evergreen or semi-evergreen low shrub, blooming in all four seasons, mostly red, or pink, occasionally white. It can be used as an ornamental plant and as a medicinal plant, and is also called Chinese rose. Its natural flowering period is from May to November. The flowers are large and fragrant, and it is widely used in horticultural cultivation and cut flowers. The main types of Chinese roses include cut-flower Chinese roses, edible roses, climbing Chinese roses, and ground-cover Chinese roses.
Growth habits
It has strong adaptability, is not tolerant of severe cold or high temperatures, and is drought tolerant. It is not strict about soil requirements, but the best is slightly acidic sandy loam rich in organic matter and with good drainage. The potting soil should be loose, the pot diameter appropriate, moisture moderate, fertilizer applied lightly and frequently, flowers removed and branches pruned, pests and diseases controlled, and the pot changed every year. It likes sunlight, but too much direct strong light is unfavorable to flower bud development, and the petals are prone to scorching. It likes warmth. Generally, 22-25°C is the most suitable temperature for flower growth, and high summer temperatures are unfavorable to flowering.
It needs sufficient sunlight, air circulation, good drainage, and a wind-sheltered environment, and needs appropriate shading in midsummer. For most varieties, the optimum temperature is 15-26°C during the day and 10-15°C at night. It is relatively cold tolerant, and enters dormancy when the winter temperature is below 5°C. If high summer temperatures continue above 30°C, most varieties bloom less, quality decreases, and they enter a semi-dormant state.
General varieties can tolerate a low temperature of -15°C. It requires slightly acidic soil rich in organic matter, fertile, and loose, but its range of soil adaptability is relatively wide. The relative air humidity is preferably 75%-80%, but slightly drier or slightly wetter is also acceptable. It has the characteristic of continuous flowering. It needs to maintain air circulation and be free of pollution. If ventilation is poor, powdery mildew is likely to occur. Harmful gases in the air, such as sulfur dioxide, chlorine, and fluorides, are all toxic to Chinese roses.
Propagation techniques
Mostly cutting propagation is used, and division and layering propagation can also be used. Cuttings can be done all year round, but winter or autumn hardwood cuttings are preferable. For greenwood cuttings in summer, attention must be paid to water management and temperature control. Otherwise, rooting is not easy. Winter cuttings are generally carried out in a greenhouse or plastic tunnel. If cuttings are taken in open ground, measures to increase moisture retention should be taken. Propagation by sowing is used for sexual hybrid breeding. For a few famous varieties that are difficult to root, grafting propagation is used, and the rootstock is preferably wild rose. Such as yellow-series varieties.
Management methods
Transplanting Chinese roses is carried out between November and March of the following year. Pruning can be done at the same time as transplanting. First cut off dense branches and dead branches, then cut off old and weak branches, leaving 2-3 outward-growing buds so they can spread in all directions. Appropriately shorten particularly strong branches to strengthen the growth of weak branches. In summer, when new branches grow too densely, thinning pruning should be carried out. After each batch of flowers fades, promptly cut off the upper part of the branch connected to the faded flower, so that it does not set seed and consume nutrients, and retain the full middle and lower parts of the branch to promote early emergence of new branches and blooming again. Chinese roses like heavy application of base fertilizer before flowering and topdressing with quick-acting nitrogen fertilizer after flowering to strengthen seedlings and promote flowers. Chinese roses have strict water requirements and cannot be too wet or too dry. Too dry causes withering, and too wet damages roots and causes leaf drop.
1. Flowering period control
Chinese rose is also called “Yueyuehong”, with a natural flowering period from May to November, blooming continuously. However, controlling the flowering period of Chinese roses during the Olympics is still very important, especially for potted Chinese roses and cut-flower Chinese roses. The flowering period must be well controlled to fully complete the tasks of temporary flower displays at various venues and gymnasiums during the Olympics and the supply of fresh cut flowers.
In actual work, analyze specific situations individually. For ground-planted Chinese roses, according to their geographical location, while ensuring continuous flowering, make them bloom more and bloom well from August 8 to 24. The following methods are for reference: Around June 20, prune all faded flowers and part of the already fully bloomed flowering branches of ground-planted Chinese roses by 50%, cutting to the round bud position at the mature middle part of the flowering branch. Their ornamental flowering period is about August 1-15. Around June 30, prune all faded flowers and all flowering branches after full bloom by the above method. Their ornamental flowering period is about August 10-25. After June 30, prune faded flowers at any time to let them bloom naturally. For potted Chinese roses and cut-flower Chinese roses, calculate the date of flower use well, and about 45 days before flower use, carry out comprehensive branch pruning.
Fertilizer and water management: In the above pruning under various circumstances, scientific fertilizer and water management should be carried out in combination with plant growth. After the plant is pruned, when the new generation of buds does not sprout, spray 0.2% urea on the leaves once every 5 or 6 days, which can promote new bud sprouting. If the plant grows quickly and new branches grow rapidly beyond the planned range, controlling water supply can delay growth. During water control, after branches and leaves wilt, spraying water promptly and recovering within 1 hour is the critical threshold. Water is the carrier of various enzymes in the plant body. If water supply is insufficient, enzyme activity decreases, metabolism slows, and therefore plant growth slows. If new branches bud later than planned, at this time spray 0.2% potassium dihydrogen phosphate on the leaves once every 5 or 6 days, and the flower buds will grow rapidly. The flowering period of Chinese roses consumes a large amount of water and internal nutrients, so water supply must be sufficient.
2. Flowering conditions
① Sunlight must be long. The place where Chinese roses are planted must be both ventilated and able to receive more than half a day of sunlight. This is the primary condition for them to bloom profusely. If placed in a half-shade half-sun location or a shaded place with insufficient light, they can bloom at most only twice a year, in spring and autumn. Therefore, families whose living conditions cannot meet the light requirements had best not grow Chinese roses and instead grow flowers and plants that are more shade-loving.
② They must be pruned often. Although sunlight conditions may be good, if they are not pruned for a long time, Chinese roses will still not grow well. The pruning method is: after December each year, when the Chinese rose leaves fall, carry out one pruning, leaving branches about 15 cm high. The pruning point should be about 1 cm above an outward-growing leaf bud, and at the same time remove side branches, diseased branches, and concentric branches. After May, each time a flush of flowers finishes, cut off 2/3 or 1/2 of that flowering branch, so there will be more opportunities for regenerated flower buds. If you want the flowers to bloom large, you can also remove part of the buds when there are many, which can both concentrate nutrients and achieve the purpose of prolonging the flowering period and opening in batches.
③ Fertilization should be frequent and timely. Generally, newly planted or transplanted potted Chinese roses can be cultivated with humus-rich and loose loess, preferably mixed with 1/4 rice husk ash or a little broad bean shell, bean cake, or chicken and pigeon manure, etc., so that the Chinese roses can continuously absorb various nutrients such as nitrogen, phosphorus, and potassium from the soil. If old potted Chinese roses need repotting, base fertilizer can also be applied as above. If not repotting, scrape open 2-3 cm of the soil surface and bank in some fresh fish intestines or chicken and pigeon manure, bean cake crumbs, etc. as base fertilizer. This is best done in January-February when Chinese roses are dormant. In this way, the fertilizer will gradually ferment into fertilizer liquid and seep into the roots with rain or irrigation water, achieving better results. After May is the peak growth season for Chinese roses. Every 10 days, apply topdressing once. You can use decomposed and fermented fishy juice or vegetable leaf juice, mixed at a ratio of 3 parts fertilizer to 7 parts water, and apply it. Stop fertilizing by November. If the above requirements can be followed, Chinese roses can meet you with fresh flowers every month. Chinese roses are naturally averse to heat. They grow best at 20-25°C; above 30°C, growth becomes difficult. If fertilization is handled well, their weakness of fearing high summer temperatures can be overcome.
④ Repotting. Chinese roses do not need to be repotted or have their soil changed every year. If moving from a small pot to a large pot, it can be done in any of the four seasons.
Early spring management
In early spring, the roots of Chinese roses begin to spread in the soil. At this time, the most important care work is pruning. In warm areas, it is in late February. In colder northern areas, pruning should be carried out in March-April. Pruning generally means cutting off about 1/3 of the plant height. First remove weak branches, diseased branches, and dead branches. The new branches produced by the plant in 2011 are the most vigorous. Choose 2-3 such main branches, at most 5, and according to the plant's original growth condition, generally prune with branch shears at a point about 50 cm above the ground and 1 cm above a healthy bud. A so-called healthy bud is one that has not yet sprouted, is plump, and has already bulged. To prevent buds from growing into overly dense branches, choose and keep healthy buds on the outer upper side of the plant. In addition, pruning should be done at a plump part of the branch. When pruning with shears, if a “click” sound is produced, that is a plump part. If the cut feels soft, prune further down to a hard place. The aged parts at the branching nodes of the plant are rough and protrude as swellings, with no strong buds at all between them, so they should also be cut off.
The middle part of 2-3 year old main branches is where new buds frequently emerge, so when pruning, leaving only 10-20 cm is enough. Generally, if you want more flowers during the flowering period, prune lightly. If you want the flowers to bloom well and do not seek many flowers, prune heavily. In addition, for plants with poor growth, one should resolutely prune heavily, because such plants have poor root development. If the crown is too large, it is easy to cause insufficient nutrient supply. At the same time as pruning, it is best to carry out one high-concentration disinfection, which has a significant effect on preventing pests and diseases.
To make the pruned branches slant outward, supports (wooden sticks, etc.) can be used to fix them, making the tree shape balanced and graceful, and avoiding friction between branches and leaves when the wind blows. Branches issued from buds at the lower part of slanted branches are more robust, and the flowers are also more abundant, so attention should be paid to protecting them.
After Awakening of Insects, insects successively wake from winter dormancy and begin activity. At this time, dissolve 10 mL of fenitrothion (insecticide) and 20 g of wettable sulfur powder used for treating powdery mildew in 10 L of water, and spray the plant with the fully dissolved concentrated solution. Because Chinese roses have not yet grown leaves at this time, there is no need to worry about phytotoxicity.
About 20 days after pruning, buds begin to swell. Among them, weak and small buds are often naturally eliminated during the sprouting process. To make the flowers bloom well, keep buds according to the thickness of the main branches: keep 3-4 buds on thick branches, keep 1-2 buds on pencil-thick branches, and remove all the rest. In colder areas, sprouting is later, so the time for removing buds can be postponed.
If base fertilizer was already applied in December, topdressing may not be needed in early spring. When buds sprout, scatter an appropriate amount of chemical fertilizer around the roots to promote bud growth. After buds sprout, on sunny days if the soil surface is dry, water in the morning or before noon to prevent the soil surface from freezing.
Summer management
Once the peak flowering period of potted Chinese roses passes, they enter the hot and humid summer, and are mostly in a dormant or semi-dormant state. Strengthening summer management of potted Chinese roses and carrying out rejuvenation care can break the dormant period and keep them blooming continuously throughout the summer. The main management measures are:
1. Shading and ventilation. Potted Chinese roses have limited soil, and in high-temperature weather the soil easily heats up and dries out, so the Chinese roses must be shaded and cooled. It is best to place the potted flowers from 8 a.m. to 4 p.m. in a ventilated place under trees in the yard or under a shed, so that the potted flowers receive scattered light and create suitable environmental conditions for the Chinese roses to grow and bloom.
2. More fertilizer and water. Chinese roses bloom many times and need sufficient nutrients and water supplied to ensure vigorous growth. Entering summer, their evaporation and consumption are both high, and growth is rapid. During the flowering period, apply diluted fertilizer once every 10 days. You can also soak bean cake and poultry manure in water, and after sealed fermentation, mix with water as topdressing, so that the plant has abundant flowers and lush leaves and the summer dormancy of Chinese roses is broken. For watering, it is best to use sun-warmed water to reduce the temperature difference between the potting soil and the water. If too-cold water is used, it will stimulate the root system and affect the plant's normal development.
3. More water spraying. In summer, in addition to appropriate shading, more water should be sprayed. It is best to spray water once in the morning and once in the afternoon to create a humid environment and promote the growth of flowers and leaves.
4. Branch thinning and pruning. After Chinese roses bloom, cut below the third compound leaf under the flower to promote the emergence of sturdy new branches and early budding and flowering. Weak and short branches should be pruned first and pruned high; robust branches should be pruned later and pruned short, so as to promote the weak and suppress the strong, and encourage uniform flowering. The pruning length of long branches should not exceed one half, to avoid delayed axillary bud sprouting. In addition, each flush should not retain too many flowers. For potted Chinese roses, 3-5 flowers are appropriate. If too many flowers are retained, nutrients are too dispersed, the flowers are small, and the next flush is affected.
5. Loosening soil and weeding. While clearing weeds on the pot surface, a thin iron wire rake can be used to gently break the surface layer around the flowerpot, enhancing the looseness and aeration of the potting soil and promoting normal root growth.
6. Pest and disease control. The site where flowerpots are placed should often be sprayed with 15% limewater or carbendazim or potassium permanganate aqueous solution for sterilization. July-August, the rainy season with high temperatures, is a high-incidence period for leaf spot disease and powdery mildew. Spray with 0.3-0.5 degree Baume lime sulfur mixture once a week, for a total of 2-3 sprays. If longhorn beetle larvae are found causing damage in June-July, the branch tips should be cut off immediately. If other leaf-eating pests are found, immediately spray 800-times monocrotophos for control, which can kill eggs and larvae.
How to grow potted Chinese roses: cultivation methods for Chinese roses
Chinese rose is honored as the queen of flowers and is one of China's ten famous flowers. Chinese roses are elegant and beautiful, with diverse appearances, and bloom in all four seasons. They are deeply loved by people and are flowers with extremely high ornamental value. So how do you grow Chinese roses? Next, Xiao Qi will share the cultivation methods for potted Chinese roses.

I. How to grow Chinese roses
Although Chinese roses are not very strict about soil requirements, loose, fertile loam rich in organic matter and slightly acidic is more suitable. They like warmth, sufficient sunlight, air circulation, and a well-drained environment. For most varieties, the optimum temperature is 15-26°C during the day and 10-15°C at night. They enter dormancy when the winter temperature is below 5°C. Some varieties can tolerate a low temperature of -15°C and a high temperature of 35°C, but when the summer temperature continues above 30°C, they enter semi-dormancy and the plant grows poorly. Although they can still form buds, the flowers are small, have few petals, and are dull and lusterless in color, losing ornamental value.
Chinese roses like water and fertilizer and cannot lose water throughout their entire life period. Especially from budding to leafing out and flowering, water should be fully supplied. During the flowering period, water demand is particularly high, and the soil should remain moist often, so that the flowers bloom large and vivid. After entering dormancy, water should be controlled and not too much. Because Chinese roses continuously sprout, send out shoots, form buds, and bloom during the growing period, fertilizer must be applied promptly and often to prevent decline in tree vigor and keep flowers blooming continuously.

II. Cultivation methods for Chinese roses
1. Temperature: Chinese roses like warmth, fear intense heat, and are relatively cold tolerant. Generally, 22-25°C is the most suitable temperature for Chinese rose growth. High summer temperatures are extremely unfavorable to Chinese rose flowering. If high temperatures continue above 30°C, flowering will decrease, and the quality of Chinese roses will also decline, entering a semi-dormant state. Chinese roses like an environment with ample sunlight, air circulation, good drainage, and shelter from wind.
2. Moisture: Chinese roses like a moist environment, and relative air humidity is best controlled between 75% and 80%. Chinese roses can also endure a certain degree of drought. In summer, it is best to spray water once in the morning and once in the evening to maintain a moist environment and promote the growth of flowers and leaves. For watering, it is best to use sun-warmed water to reduce the temperature difference between the potting soil and the water.
3. Soil: The soil for growing Chinese roses is best rich in organic matter, fertile, loose, slightly acidic, and well drained. Compacted soil and calcareous soil are not conducive to the growth of Chinese roses. In fact, Chinese roses also have a relatively wide range of soil adaptability.
4. Pruning: The first post-flowering pruning is carried out in mid-to-late May. Promptly cut off faded flowers to avoid seed setting, so as to concentrate nutrients for sprouting new branches and make the second bloom large and beautiful. For relatively strong branches, prune lightly to appropriately suppress their growth, retaining 4-5 buds. When pruning, note that the cut should be 0.5 cm above the bud. Too high not only affects appearance but also delays branch sprouting.
5. Propagation: When in school, I often liked to use the cutting method to grow Chinese roses. Chinese roses have extremely strong vitality. At that time, I would directly break off a branch of a Chinese rose and insert it into soil, and it would grow smoothly after a week. Here I will introduce a more scientific method to you: cut the removed branches into 10-15 cm segments, insert them into nutrient pots or small flowerpots, place them in a place with weaker light, and maintain a temperature of about 20°C. After roots form and leaf buds grow into branches, they can be repotted and transplanted.
6. Pest and disease control: The site where flowerpots are placed should often be sprayed with 15% limewater or carbendazim or potassium permanganate aqueous solution for sterilization. July-August, the rainy season with high temperatures, is a high-incidence period for leaf spot disease and powdery mildew. Spray with 0.3-0.5 degree Baume lime sulfur mixture once a week, for a total of 2-3 sprays. If longhorn beetle larvae are found causing damage in June-July, the branch tips should be cut off immediately. If other leaf-eating pests are found, immediately spray 800-times monocrotophos for control, which can kill eggs and larvae.
