Rose belongs to the Rosaceae family and has high economic and ornamental value. The color of the rose is bright and beautiful, the fragrance is pleasant, and it is a famous raw material for perfume, with high value. Rose is a treasure among ornamental flowers, widely cultivated in the country, deeply loved by flower enthusiasts, and one of the main flowers for courtyard cultivation.
I. Propagation methods of roses
The propagation of roses is very easy. There are several methods of rose propagation, including sowing (single-petaled roses can be propagated by seed sowing, collecting the rose fruits in October when they are mature, and either sowing immediately or storing them in sand until March of the following year, and transplanting in autumn), division (performed during the dormant period of the rose), grafting, and cutting propagation. Usually, cutting propagation is adopted, cutting semi-woody branches in June into segments of 10-15 centimeters and inserting them into a pot or flower pot filled with sandy soil. After watering sufficiently, cover the pot tightly with plastic film. Under the conditions of 20-30°C, it takes about a month for roots to grow. After the cuttings have rooted, they should be transplanted promptly.
III. Preparing the cultivation soil, usually in the courtyard, ground planting is adopted, while in the city, pot cultivation is mainly used. The cultivation soil for roses should be loose with good drainage and water retention. The potting soil for roses is prepared with 20-30% compost, 30-40% garden soil, and 30% wood ash.
IV. Rose cultivation, potting roses should use clay pots, usually with pots over 27 centimeters in diameter. Potting is usually done in spring, autumn, or during the dormant period of the rose. Place broken tiles at the bottom of the pot, then fill in the cultivation soil, and place the rooted cutting of the rose in the center of the pot. The roots should be spread out. Fill the soil to half the pot and gently shake the rose plant to compact the soil. When planting, it should not be too deep; keeping the rootstock level with the pot opening is sufficient. If it is too shallow, it will affect survival, and if it is too deep, it will affect the growth of the transplanted roses. After planting, water thoroughly. After planting, keep the plant in a shaded environment for a week and then move it to a sunny place after the roots have recovered.
V. Water and fertilizer management, during the growth and development period, water with fertilizer every 10-15 days. In dry weather, water every 1-2 days, and in hot summer and early autumn, water every day. Water appropriately before blooming, and after the rain, make sure to pour out the accumulated water in the pot. Especially in the summer, insufficient water supply can cause leaf drop, so water in the morning and evening, and in autumn, water after the soil is dry in the afternoon. In winter, when the rose plant is in a dormant state, control the watering. After flowering, reduce watering. Excessive soil moisture can cause leaf drop and root rot.
VI. Pruning, after defoliation, pruning should be done. The pruning amount can be larger, mainly thinning out diseased, withered, and dense fine branches. For the remaining branches, strong branches should be cut by half, and weak branches by two-thirds.
VII. Pot changing, as roses grow vigorously and the roots can quickly fill the entire pot, it is necessary to change the pot every 1-2 years. Pot changing should be done in early spring before the rose begins to sprout, cutting off old roots and replacing with new soil.
