Chinese Rose
The editor introduces you to the introduction of other flowers related to Chinese Rose (Yue Yue Hong), the maintenance methods of Chinese Rose (Yue Yue Hong), and the specific details are as follows:
Known as the "Queen of Flowers," Chinese Rose, also called "Yue Yue Hong," has a natural blooming period from May to November, with continuous blooming. It has strong adaptability, cold and drought resistance, and is not strict with soil requirements, but it thrives best in slightly acidic sandy loam rich in organic matter and good drainage. It loves light but excessive strong sunlight is detrimental to bud development, easily causing petals to scorch. It prefers warm temperatures, with a general range of 22-25°C being most suitable. High summer temperatures are unfavorable for blooming.
It enjoys sufficient sunlight, air circulation, good drainage, and a windless environment, requiring appropriate shading during midsummer. The optimal temperature for most varieties is 15-26°C during the day and 10-15°C at night. It can tolerate cold to some extent, entering dormancy when temperatures drop below 5°C in winter. Continuous high temperatures above 30°C in summer lead to reduced blooming and quality in most varieties, entering a semi-dormant state. Most varieties can tolerate low temperatures down to -15°C. It requires soil rich in organic matter, fertile, and slightly acidic, but has a wide adaptability range. The relative humidity of the air should be 75%-80%, but it can tolerate slightly dry or slightly moist conditions. It has the characteristic of continuous blooming. It needs to maintain good air circulation and be free from pollution; poor ventilation can easily lead to powdery mildew, and harmful gases in the air, such as sulfur dioxide, chlorine, and fluoride, are toxic to Chinese roses.
Propagation: The most common method is cutting propagation, but it can also be propagated by division or layering. Cuttings can be done all year round, but it is best to use woody cuttings in winter or autumn, while green cuttings in summer require attention to water management and temperature control. Otherwise, it is not easy to root. Winter cuttings are generally done in greenhouses or plastic tunnels, and if done outdoors, measures to increase humidity are needed. Those propagated by seeds are used for sexual hybrid breeding. For a few difficult-to-root varieties, grafting is used, with wild roses as the rootstock, such as yellow series varieties.
Management: The移植 (transplanting) of Chinese roses is carried out between November and the following March. Pruning can be done at the same time as transplanting, first removing dense and withered branches, then cutting off old and weak branches, leaving 2-3 outward-growing buds for expansion; overly strong branches should be shortened to strengthen weak branches. In summer, when new branches grow too dense, thinning should be done. After each batch of flowers fades, the top part of the branch connected to the残花 (withered flowers) should be cut off to prevent seed formation and conserve nutrients, while the strong branches in the middle and lower parts should be retained to promote the early growth of new branches and reblooming. Chinese roses require a heavy application of base fertilizer before blooming and a rapid nitrogenous topdressing after blooming to strengthen seedlings and promote flowering. Chinese roses are strict with water requirements; they should not be too wet or too dry, as excessive dryness leads to withering, and excessive moisture harms the roots and causes leaf drop. The main pests are aphids, leaf-rolling moths, and tussock moths, which can be controlled with 1000-1200 times the concentration of dimethoate or samide pesticides.
Propagation is mainly through grafting and cuttings, with seeding and tissue culture as auxiliary methods. Common rootstocks for grafting include wild roses, pink roses, and "White玉堂" (rose). When planting Chinese roses outdoors, choose a location with a sunny, leeward, and well-drained environment. In addition to applying a heavy base fertilizer, topdress fertilizers should be added during the growing season. Pruning is an important task; in addition to dormant season pruning, attention should also be paid to bud removal, cutting off withered flower branches, and rootstock suckers. Greenhouse cultivation is mainly for the production of (G-Y) cut flowers, often planted at a spacing of 30cm x 30cm, with night temperatures maintained at 15-17°C and day temperatures at 21-25°C. Chinese roses can also be potted for indoor display. The key points for cultivation management are: loose potting soil, appropriate pot size, moderate moisture, frequent application of thin fertilizer, flower pruning, pest and disease control, and pot replacement every year.
