The roots of miniature rose plants are shallow. Before germination in spring, the pot soil should be kept moist, and the soil should not be dried or watered. After germination, the watering amount should be increased gradually. Generally, it should be watered once before 10 a.m. every day, and in the afternoon, it should be watered appropriately according to the dry and wet conditions of the pot soil. In summer, water should be poured once in the morning and once in the evening, but not at night.
Micro rose is fond of fertilizer. In spring and autumn, when it grows vigorously, it should be topdressing once every 10-15 days. Organic fertilizer and compound fertilizer can be applied. Fertilization should be stopped in high temperature season in summer and low temperature in winter.
Most of the propagation methods of Mini Rose are Cuttage Propagation, which can also be divided into plants and pressed.
Cuttage can be carried out all the year round, but it is better to use stem cuttage in winter or autumn, and pay attention to water management and temperature control in summer.
At the same time, grafting can also be used. Rosa acerifolia is often used as rootstock, and bud grafting is carried out in early spring or growing season, especially the effect of bud grafting is better.
Some branches should be cut off after flower withering, and 2-3 sections of new branches should be cut off. More than 2 sections of the cut branches are used for cutting propagation. In winter, pruning mainly focuses on shaping. First, prune dead branches, disease and insect branches, and cross thin and weak branches. For plants with strong growth and well-balanced plant type, cut 1 /3 of the whole plant. For the plants with weak growth, about 2 /3 of the whole plant is cut and 3-4 strong main branches are left.
Turn the basin every 1-2 years, remove about 2 /3 of the old soil, and replace it with loose, fertile and rich organic soil. Most of them are carried out before sprouting in spring. Combined with turning basin, the withered roots, rotten roots and plant and insect roots are cut off, the long roots are shortened, the dense roots and some old roots are sparse, so as to promote the germination of new roots and make them grow vigorously.
The main diseases of the Miniature Rose are powdery mildew, grey mould and black spot. The common pests are aphid, red spider and sawfly.
The main control method is to carry out scientific cultivation, enhance the disease resistance of plants, and remove dead branches and leaves in time. In addition, you can go to the flower market to buy special chemicals for spraying.
