Precautions for growing Chinese roses at home
Chinese rose: The Chinese rose has strong adaptability to the environment and prefers warmth. It grows best at an average temperature of 22---25 degrees. The Chinese rose is not strict about soil, but grows vigorously in fertile, loose and slightly acidic soil. During the growing period, sunlight must be sufficient, otherwise the plant will be weak, the leaves will turn yellow, and the flowers will be small and off-color. Chinese roses must be pruned, and the pruning period is generally before and after flowering in spring and autumn. Remove diseased and weak branches, crossing branches, inward-growing branches, as well as dead branches and spent flowers. In hot summer, the soil dries out very easily, so water must be given in good time to keep the soil moist; especially during bud formation and the flowering period, the water supply must not be lacking. In the rainy season, accumulated water must be drained promptly. In winter, it is best to place them in a cellar to let them go dormant, and around mid-March of the following year, take them out and prune them.

The Chinese rose is also called “Yueyuehong” and is the city flower of Beijing and other cities. So what are the methods and precautions for growing Chinese roses? What is the difference between Chinese roses and roses? Below, the editor of wed114 wedding website brings you the relevant information.
How to grow Chinese roses and precautions, with a detailed explanation of the difference between Chinese roses and roses
Regarding the Chinese rose, it is necessary to make an identification and distinction. We all know that roses, Chinese roses and Rosa multiflora are all plants of the genus Rosa, with differences in species among them, but no difference at the family or genus level. In China, people are used to calling varieties with large flowers and solitary blooms roses or Chinese roses, and those with small clustered flowers Rosa multiflora. But in English they are all called rose. Therefore, we should also be able to guess that the flower language of the Chinese rose is not much different from the flower language of the rose.

Legend of the Chinese rose: It is said that long ago, at the foot of Shennong Mountain, there was a family surnamed Gao with a daughter named Yulan, eighteen years old, gentle and quiet. Many young noblemen and princes came to propose marriage, but Yulan refused them all. This was because she had an elderly mother who coughed and spat blood all year round, and no matter what medicines were used, they were completely ineffective. So Yulan, without telling her parents, posted a notice seeking medical treatment: “Whoever cures my mother's illness, I am willing to marry him.” A young man named Zhongyuan responded to the notice and offered a prescription. After Yulan's mother took his medicine, she indeed recovered. Yulan did not break her promise and married Zhongyuan. On their wedding night, Yulan asked what miraculous prescription was so effective, and Zhongyuan replied: “Chinese rose, Chinese rose, a good remedy for clearing cough. This is a secret family recipe: stewed rock sugar with Chinese rose flowers is a miraculous decoction for clearing cough and stopping bleeding, specially treating women's illnesses.”

How to grow Chinese roses and precautions:
Flowering period control
The Chinese rose is also called “Yueyuehong”, with a natural flowering period from May to November, blooming continuously. However, during the Olympics, controlling the flowering period of Chinese roses is still very important, especially for potted Chinese roses and cut-flower Chinese roses. The flowering period must be well controlled to successfully complete the tasks of temporary flower displays at various venues and stadiums during the Olympics and the supply of fresh cut flowers.
In actual work, specific situations should be analyzed specifically. For field-grown Chinese roses, according to their geographical location, while ensuring continuous flowering, let them bloom more and bloom well from August 8 to 24. The following methods are for reference: around June 20, prune all spent flowers and part of the already fully bloomed flowering branches of field-grown Chinese roses at a ratio of 50%, cutting to the round bud position at the mature middle part of the flowering branch; their ornamental flowering period is about August 1 to 15; around June 30, prune all spent flowers and all flowering branches after full bloom according to the above method; their ornamental flowering period is about August 10 to 25; after June 30, prune spent 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 various pruning situations, 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 to 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 the branches and leaves wilt, spray water promptly, and recovery within 1 hour is the critical point. Water is the carrier of various enzymes in the plant body. Insufficient water supply lowers enzyme activity and slows metabolism, thus slowing plant growth. If new branches bud later than planned, spray 0.2% monopotassium 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 the water supply must be sufficient.

Flowering conditions
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-shaded, half-sunny place or a shaded place with insufficient light, they can bloom at most only in spring and autumn in a year. Therefore, households whose living conditions cannot meet the light requirements had best not grow Chinese roses and instead grow shade-loving flowers and plants.
Prune frequently. Although the sunlight conditions are good, if they are not pruned for a long time, Chinese roses will not grow well either. The pruning method is: after December each year, when the Chinese rose leaves fall, carry out one pruning, leaving branches about 15 cm high, with the pruning position about 1 cm above an outward-extending leaf bud, and at the same time remove side branches, diseased branches and concentric branches. After May, each time a round of flowering ends, prune away 2/3 or 1/2 of the branch that has flowered, so there will be more opportunities for regenerated flower buds. If you want the flowers to be larger, you can also remove part of them when there are many flower buds, which can both concentrate nutrients and achieve the purpose of extending the flowering period and opening in batches.
Fertilizing 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 small amount of broad bean shells, soybean cake or chicken and pigeon manure, etc., so that the Chinese rose can continuously absorb various nutrients such as nitrogen, phosphorus and potassium from the soil. If an old potted Chinese rose needs repotting, base fertilizer can also be applied as above; if not repotting, you can scrape open 2-3 cm of the soil surface and bury some fresh fish entrails or chicken and pigeon manure, soybean cake crumbs, etc. as base fertilizer. This is best done in January to February when the Chinese rose is dormant. In this way, the fertilizer will gradually ferment into fertilizer liquid and seep into the roots with rain or watering, achieving better results. After May is the peak growing season for Chinese roses. Every 10 days, apply a topdressing once. You can use fully fermented fish juice or vegetable leaf juice mixed with 3 parts fertilizer to 7 parts water and apply it, and stop fertilizing in November. If you can do as required above, you can make the fresh flowers of the Chinese rose meet you every month. The Chinese rose is by nature averse to heat, and grows best at a temperature of 20-25°C; above 30 degrees, growth becomes difficult. If you handle fertilization well, you can overcome its weakness of fearing high temperatures in summer.
Repotting. Chinese roses do not need to be repotted or have their pots changed every year. If it is moving from a small pot to a large pot, it can be done in any of the four seasons.

The difference between Chinese roses and roses
The rose has tall stems, mostly straight thorns, small flowers, a single flower color, and a short flowering period. The flowering branches are upright, the flower colors are rich, and it is fragrant. Rose leaflets are also 5-9 in number, but the underside of the leaf is wrinkled, the leaf back is whitish with small prickles, and the whole leaf is relatively thick with sunken veins. The Chinese rose has low stems, large thorns, with roughly 3 or 4 hooks per node; large flowers, rich flower colors, a faint scent or no scent, and leaflets generally 3-5 in number, with flat and smooth leaf blades.

——————————————————————————————————————————————
After the flowers fade in winter, we can promptly cut off the upper part of the branch connected to the spent flowers so that they do not set seed and consume nutrients, retaining the plump middle and lower branches to promote early new branch growth and blooming again. For some varieties with excessively strong tree vigor that only produce branches without forming flower buds, their shoot tips can often extend to more than 1 meter without any flower buds appearing. At this time, pruning can be done by cutting back according to the flowering height of the first batch of flowers to adjust tree vigor, inhibit the excessively strong upward-extending tree vigor, and promote new shoots from the base. If base fertilizer was applied in January or February, no fertilizer need be applied in early spring. When budding begins, sprinkle an appropriate amount of chemical fertilizer around the roots to promote budding. When leaves unfold in early spring, new roots grow in large numbers, so fertilizer should be applied in small amounts, and no concentrated fertilizer should be applied, so as not to affect new root growth. During the flowering period, apply a light topdressing once every 10 days, so that the plant has abundant flowers and lush leaves.How to grow Chinese roses in summer
——————————————————————————————————————————————
[1]Shade and ventilation. The soil in potted Chinese roses is limited, and in high-temperature weather it easily heats up and dries out, so the Chinese rose must be shaded and cooled.
[2]Fertilize more. Chinese roses bloom many times and need sufficient nutrients and water supplied to ensure vigorous growth. Entering summer, both evaporation and consumption are large, and growth is rapid. During the flowering period, apply a light topdressing once every 10 days, so that the plant has abundant flowers and lush leaves, breaking the summer dormant state of the Chinese rose.[3]Spray water more. The Chinese rose enters a semi-dormant state above 33°C, and grows best at an average temperature of 20-25°C. Therefore, in summer, in addition to appropriate shading, more water should be sprayed, preferably once in the morning and once in the afternoon, to create a moist environment and promote the growth of flowers and leaves.
[4]Thinning and pruning. After the Chinese rose blooms, it should be cut below the third compound leaf under the flower to promote strong new branches and early bud formation 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.
[5]Loosen the soil and remove weeds. Along with clearing weeds on the pot surface, you can use a fine wire rake to gently break the surface layer around the flower pot, enhancing the looseness and aeration of the potting soil and promoting normal root growth.
[6]Prevent and control pests and diseases. Frequently spray 15% limewater or carbendazim and potassium permanganate aqueous solution for sterilization.How to grow Chinese roses in autumn

Entering autumn, the temperature gradually decreases. In order to make the tissues of the Chinese rose grow more substantially, the amount of watering should also be reduced somewhat. At this stage, it is another peak period of Chinese rose flowering. If you want the flowers to bloom well and brightly, fertilizer should be supplemented in good time. You can apply a liquid fertilizer rich in phosphorus and potassium once a week. It must be ensured that the Chinese rose receives more than 4 hours of direct sunlight every day, so that it can grow with lush leaves and abundant branches.How to grow Chinese roses in winter
——————————————————————————————————————————————
What is the focus of winter management of Chinese roses? Whether field-grown Chinese roses or potted Chinese roses, winter is the most important management period. Whether the care is in place directly relates to normal growth and flowering in the coming year. The main points are to do a good job in the following aspects:
[1]Fine pruning: In late autumn and early winter, when the ambient temperature drops below 5°C, first cut off dead branches, diseased and pest-infested branches, crossing branches, overlapping branches, etc., and then according to the plant's growth, use three different methods, strong, medium and weak, for pruning. For weak plants whose growth is not robust enough, strong pruning should be used; for plants with normal growth, moderate pruning should be given; for small and medium plants with robust growth and normal development, weak pruning should be given to prevent excessive nutrient consumption.[2]Bury fertilizer: For field-grown plants, after pruning is completed, dig ring-shaped trenches around the outer part of the plant's root system, and depending on the size of the plant, bury 250 grams to 300 grams of oil cake per plant to meet the needs of growth and flowering in the coming year.
[3]Pay attention to cold protection: Because winter is relatively cold, Chinese roses cultivated in the open field should not be heavily pruned in winter, to prevent wind drying and damaging the branches. Pruning can be done before sprouting the following spring. Note that for plants placed indoors, the greenhouse temperature should not be higher than 4°C to 5°C, so that they can enter full dormancy.[4]Cuttings from strong branches: For some Chinese rose varieties that root relatively easily, such as ‘Yueyuehong’, ‘Floribunda’, ‘Miniature’ Chinese roses, etc., the thick one-year-old branches cut off can be cut into 10 cm to 12 cm segments, with the lower cut located 0.2 cm below the node. Use yellow subsoil as the cutting bed. Insert the cuttings to a depth of 4/5, leaving only one bud at the end above the soil. After watering thoroughly, set up an arched frame, cover it with plastic film and press the edges firmly. When the weather is too cold, add straw curtains for cold protection, keeping the seedbed from freezing. By the following spring, the lower cut will heal and take root.
