Miniature roses occupy a small area of flowers and still bloom with the old gardener.

Rose is one of the top ten famous flowers in China. Widely cultivated, there are many varieties, and roses have strong adaptability. It can be planted on the ground or potted. It is suitable for beautifying courtyards, decorating gardens, arranging flower beds and potted plants, and is also an important material for cut flowers. The main types of roses are vine rose, perfume rose, abundant rose, mini rose, tree rose, strong rose, shrub rose and ground cover rose. Today, I will introduce a kind of rose suitable for potted plants-Yue Wei rose, which is a modern rose. Its plant type is short and compact, spherical, with many flower heads, and it is also called' diamond rose' because of its unique character. Micro-rose is a new variety of Rosaceae, with short plants, bright colors, flowering all year round, low requirements for space, and even small balconies can be cultivated. Very suitable for potted plants. Micro-roses like warmth, fatness and lightness, and require good air circulation and drainage. Generally speaking, the requirements for soil are not strict, but slightly acidic soil with loose air permeability, rich organic matter content and pH value of 5.5~6.0 is suitable. The suitable growth temperature is 15~26 in the daytime and 10~ 15 at night. Longer illumination time can make miniature rose blossom early, obviously increase the number of flowers, and make the plant shape more compact and beautiful. High temperature can promote the early flowering of miniature rose, while low temperature will delay its flowering, and the delay effect is more obvious when the temperature is lower than 13. When the temperature is higher than 24℃, the net photosynthetic rate of plants will decrease. Too much water can easily lead to yellowing of leaves and root shedding. It is difficult for plants lacking water to recover themselves. In addition, in the case of more fertilization, water shortage is easy to cause soluble salt damage. The propagation method of micro-roses generally adopts cutting propagation, which can be carried out all year round, but hard branch cutting should be used in winter or autumn. Cut off the strong branches of newly withered flowers as cuttings, cut off the residual flowers and lower leaves, keep the upper 1~2 leaves, soak 1~2 hours in 0.05 solution of indoleacetic acid or naphthylacetic acid, then fold, accounting for about 15~20%, and take root. Cutting in winter is generally carried out in greenhouse. For example, in the open field, we should pay attention to increasing moisturizing measures. For a few varieties that are difficult to take root, grafting can be used for propagation, and wallflower without thorns is often used as rootstock, which can be grafted in early spring or germinated in the growing season, especially bud grafting. Management point 1. Water miniature rose has small plants and shallow roots, so the basin soil should be kept moist before germination in spring, and the watering amount should be gradually increased after germination. The best watering time is before 10 every morning. If the air is dry, the evaporation of water is relatively large. In the afternoon, water can be properly replenished according to the dry and wet conditions of the basin soil. 2. Fertilizing miniature roses is a plant that loves fertilizers. Spring and autumn are vigorous growth periods, and should be applied every 10~ 15 days. Organic fertilizer or compound fertilizer can be used. Fertilization should be stopped in high temperature season in summer and low temperature season in winter. 3. Maintaining the environment Micro-rose is a pleasant plant, so it should be maintained in a well-lit and ventilated place. Miniature rose is relatively cold-resistant, dormant at low temperature in winter, and has strong cold resistance in dormant state. 4. Prune the miniature rose properly and cut off some branches after it withers. After pruning in winter, plastic surgery is the main method. First, cut off dead branches, pests and diseases, and cross branchlets. For plants with vigorous growth and well-proportioned plant types, 1/3 of the whole plant should be cut off. For plants with weak growth, cut off about 2/3 of the whole plant and leave 3~5 strong main branches. 5. Rotate the basin regularly. Turn over the basin once every 1~2 years, remove 2/3 of the old soil and replace it with loose and fertile soil rich in organic matter. Before spring germination, soil should be changed, combined with turning pots, and dead roots, rotten roots and pest roots should be cut. 6. Pest control The main diseases of miniature roses are white powder, gray mold and black spot, which can be controlled by triadimefon and thiophanate-methyl. There are aphids, red spiders,

As long as the temperature is suitable, flowers can bloom all year round, so the blooming flowers should be cut off in time. In order to grow more flowers, some blind branches or weak branches should also be cut off. Mini rose is a relatively pruning-resistant plant. If there is enough fertilizer, it will continue to bloom.
