First, how to raise rose flowers

Although the rose is not strict with the soil, the loam which is loose, fertile, rich in organic matter and slightly acidic is more suitable. Sex likes a warm, sunny, well-ventilated and well-drained environment. The optimum temperature of most varieties is 15 ~ 26 degrees in daytime and 10 ~ 15 degrees in the evening. When the temperature is below 5 degrees in winter, it goes into dormancy. Some varieties can withstand the low temperature of minus 15 degrees and the high temperature of 35 degrees, but when the summer temperature lasts above 30 degrees, it enters semi-dormancy, the plant growth is poor, although it can also conceive buds, but the flower petals are few, the color is dim and dull, and it loses its ornamental value.

Rose likes water, fertilizer, can not lose water throughout the life cycle, especially from budding to leaf release, flowering stage, should be fully water supply, flowering water needs a lot, the soil should always keep moist, such flowers hypertrophy, bright. After entering the dormant period, it is necessary not to control too much water. As the rose continues to sprout, shoot, bud and blossom during the growing period, timely and regular fertilization must be applied to prevent the decline of the tree potential and make the flowers bloom continuously.

Second, the culture method of Chinese rose

1. Temperature: rose flowers like warmth, fear of heat, and are more resistant to cold. The most suitable temperature for the growth of Chinese rose is 22-25 ℃. The high temperature in summer is extremely disadvantageous to the flowering of Chinese rose. If the high temperature lasts for more than 30 ℃, the flowering will decrease, and the quality of Chinese rose will decrease and enter the semi-dormant state. Rose flowers like sunny, well-ventilated, well-drained and sheltered environment.

2. Moisture: rose flowers like a humid environment, and the air relative humidity is best controlled between 75% and 80%. Rose flowers can also withstand a certain degree of drought. It is best to spray water once in the morning and evening in summer to maintain a humid environment and promote the growth of flowers and leaves. Sun-dried water should be used for watering to reduce the temperature difference between basin soil and water.

3. Soil: the soil planted with rose had better contain organic, fertile, loose, slightly acidic and good drainage, while consolidated soil and calcareous soil are not conducive to the growth of rose. In fact, the rose flower has a relatively wide range of adaptation to the soil.

4. Pruning: the first post-anthesis pruning is carried out in the middle and late May, and the residual flowers should be cut off in time to avoid fruiting, so as to concentrate nutrition and germinate new branches, so that the secondary flowers can bloom large, beautiful and strong branches, and can be cut lightly in order to properly restrain its growth. just keep 4-5 buds. When pruning, it should be noted that the cut should be 0.5 cm above the bud, too high will not only affect the appearance, but also delay the germination of branches.

5. Reproduction: when I go to school, I often like to plant Chinese rose by cutting, which has strong vitality. It will directly pick the branches of Chinese rose and insert it into the soil, and it will grow smoothly after a week. Here we introduce a more scientific method for you, ha: cut the cut branches into 10-15 cm branches, insert the cuttings into a nutrition bowl, or a small flowerpot, put them in a place with weak light, maintain a temperature of about 20 degrees, and wait for rooting and leaf buds to grow branches. You can change the pot and transplant.

6. Prevention and control of diseases and insect pests: the flowerpot placement site should often be sterilized with 15% raw lime water or carbendazim or potassium permanganate solution. The high temperature in the rainy season from July to August is the high incidence period of leaf spot and powdery mildew. Baume 0.3: 0.5 degree stone-sulfur mixture can be sprayed once a week for a total of 2 times. The larvae of longicorn beetles were found to be harmful from June to July, and the branches should be cut off immediately. Once other leaf-eating pests are found, they should be sprayed with 800 times monocrotophos, which can kill eggs and larvae.

The above is how to raise Chinese rose and the breeding method of Chinese rose, the adaptability of Chinese rose is still very strong, the breeding process is mainly to prevent diseases and insect pests, we might as well start breeding a few pots.
