The Fastest Method for Rooting Cuttings of Chinese Roses and Cultivation Techniques
Chinese roses are evergreen or semi-evergreen low shrubs of the Rosaceae family, known as the queens of flowers. They have beautiful and diverse colors, bloom throughout the year, and are deeply loved by people. China has 52 cities that have chosen them as the city flower, and they were even rated as the fifth among the top ten famous flowers in China in May 1985.
The Fastest Method for Rooting Cuttings of Chinese Roses
1. Choose branches: Select healthy branches free of diseases and pests, usually one-year-old softwood branches are sufficient, each section should be 7-12 cm long. The stronger the cutting branches, the easier they will root.
2. Cutting branches: Cut the lower end of the cutting branches diagonally, remove all leaves at the bottom, leaving 2-3 leaves at the top. The cutting scissors must be sharp and not rusty, and it's best to wipe them with alcohol first.
3. Cutting method: Soak the branches in a rooting solution or dip them in rooting powder before cutting. Then insert the branches into prepared water, preferably rainwater, cool boiled water, or tap water that has been exposed to the sun for 2-3 days.
4. Post-cutting management: Change the water of the cut Chinese rose branches every 3-5 days, preferably pour out 1/2 and then add enough clean water. There's no need to change the water after the roots have grown. Once the roots reach about 4-5 cm, they can be transplanted into the soil.
What are the Propagation Methods of Chinese Roses?
1. Grafting: The common rootstock for grafting Chinese roses is wild roses, which can be divided into bud grafting and branch grafting. Bud grafting has a higher survival rate and is usually done from August to September. After grafting, provide proper shading and the grafts will heal in about two weeks.
2. Sowing: Chinese roses can be sown in holes or trenches, usually germinating in mid to late April. There are two transplanting times, spring and autumn, usually done after the leaves fall in late autumn or before the sap flows in early spring.
3. Division: Division of Chinese roses is often done in early spring or late autumn. The method is to dig up the whole rose plant with soil and divide it, with each plant having 1 to 2 branches and a bit of fibrous roots. Plant them in pots or in the open ground, and they can bloom in the same year.
4. Cutting: Chinese roses are usually cut in early spring or late autumn when the plants are dormant, taking mature branches with 3 to 4 buds. If using softwood cuttings, provide proper shading and keep the seedbed moist. It usually takes 30 days to root, with a survival rate of 70% to 80%.
5. Layering: Layering of Chinese roses is usually done in summer. Bend the rose branches down from the parent plant and press them into the soil, removing half of the bark from the bottom circle to expose the branch tip. Cut off from the parent plant after the branch has developed adventitious roots and new leaves.
How to Cultivate Chinese Roses to Thrive?
1. Soil: Chinese roses are not picky about soil but prefer slightly acidic soil rich in humus. It is generally recommended to choose fertile, loose, and well-drained soil. Pots should have holes at the bottom and be padded with some pebbles to maximize drainage.
2. Light: Chinese roses enjoy a sunny and well-ventilated environment. Do not place them in dark and damp areas. To avoid direct sunlight, they can be temporarily placed in the shade, especially during the flowering period, as otherwise, the flowers may wither.
3. Temperature: Chinese roses prefer a warm environment but are afraid of heat. Therefore, proper shading is needed during summer cultivation. During extreme heat, they can be moved indoors. The most suitable temperature is between 22-25℃.
4. Watering: Chinese roses enjoy a warm and humid environment with an air humidity of 75-80% being most suitable. They can also tolerate slight drought. Follow the principle of watering only when dry and watering thoroughly when done. The timing and amount of watering should be based on the condition of the soil in the pot.
5. Fertilizing: Chinese roses are in their growth peak from May. Every 10 days, they should be fertilized once. Fertilizers don't need to be purchased specifically and can use fermented fish sauce or vegetable leaf juice, with a fertilizer-water ratio of about 3:7. Fertilizing continues until November.
6. Pruning: Chinese roses have long vines. Allowing them to grow freely not only fails to shape them but also affects growth and flowering. Therefore, they should be trained to grow well on pre-arranged supports to form unique ornamental shapes.
7. Pest prevention: For routine pest and disease control of Chinese roses, you can use 15% lime water spray or sterilizing solution, etc. From July to August, it is necessary to inspect and control weekly. The medicine should be sprayed 2-3 times a week for prevention, and any diseased branches and leaves should be cut off promptly.
