Cultivation method of mini rose
1, humidity control
Micro-rose plants are small and have shallow roots, so the soil should be kept moist before germination in spring, and the watering amount should be gradually increased after germination, and the best watering time is before 10 every morning. If the air is dry and the evaporation of water is relatively large, an appropriate amount of water can be added in the afternoon according to the dryness and wetness of the basin soil.
2. How to apply fertilizer
Micro-rose is a fertilizer-loving plant, which grows vigorously in spring and autumn. Top dressing is required for 65,438+0 times every 65,438+00 ~ 65,438+05 days, and organic fertilizer or compound fertilizer can be used. It is particularly important to note that fertilization should be stopped in high temperature season in summer and low temperature season in winter.
3. Breeding grounds
Micro-rose is a sunny plant, so it should be placed in a place with sufficient sunlight and good ventilation. In hot summer, it should be properly shaded to avoid burning branches and leaves. Micro-roses are cold-resistant, and there is no problem in outdoor maintenance in winter.
4, appropriate pruning
After the miniature rose withers, some branches should be cut off. After winter, pruning mainly focuses on plastic surgery. First, cut off dead branches, diseased branches and crossed twigs. For plants with vigorous growth and symmetrical plant types, the whole plant 1/3 should be cut off. For plants with weak growth, about 2/3 of the whole plant is cut off, leaving 3 ~ 4 strong main branches.
5. Turn the basin regularly
Turn over the pots every 1 ~ 2 years, remove 2/3 of the old soil and replace it with loose, fertile soil rich in organic matter. This step is generally carried out before germination in spring, combined with turning pots to cut off dead roots, rotten roots and pests and diseases.
Understand the habits of mini-rose
Miniature roses like light, are not tolerant of shade, are gentle, and are afraid of heat and cold. The optimum growth temperature is 15℃ to 25℃. Below 5℃, it will enter a dormant period, and above 30℃, it will grow poorly.
Ps: Some flower lovers will go into a misunderstanding that potted miniature roses can be kept indoors. Actually, it is not. Even miniature roses are a kind of roses, and indoor maintenance is not good for their growth. However, because the miniature rose plants are short, small and shallow, problems will occur if they are exposed to the sun in hot summer. Flower lovers should pay attention.
Matters needing attention in the cultivation of small rose
Fertilization: The fertilization ratio of Chinese rose is 3 parts of fertilizer and 7 parts of water. Fertilization interval is about 10 day, and fermented gravy can be used. 1 1 month can stop fertilization.
Key points of watering: May is the peak season of small rose, and the principle of watering is not to dry it, but to water it thoroughly.
Pruning points:
(1) Small rose flowers should be pruned frequently. The pruning method is to prune lateral branches, diseased branches and concentric branches, so that there will be more regenerated flower buds.
(2) Generally, the small flowers of Chinese rose are pruned in the middle and late May to concentrate nutrition and let new buds sprout. Don't cut too hard. When pruning, it should be trimmed at the nail length above the new bud, which is conducive to growth.
Change pots: Little Chinese rose flowers don't need to change pots and turn pots every year, and they can be changed from small pots to large pots all year round.
Key points of propagation: Chinese rose flowers are generally propagated by cutting or layering. Cutting can be carried out all year round, but hard branch cutting in winter and autumn is suitable. Cuttings are usually carried out in greenhouses or greenhouses in winter. If you are cutting in the open field, you should pay attention to moisturizing and heat preservation measures. Attention should be paid to water management and temperature control in autumn twig cutting, otherwise it is not easy to take root.
Pest control: The usual pest control of rose florets can be mixed with 15% quicklime and water, or with disinfectant. Chinese rose is prone to diseases from July to August of a year. At this time, it is necessary to strengthen prevention and control, check and prevent it in time every week, spray chemicals 2-3 times a week for prevention, and cut off diseased branches and leaves in time.
