How to plant rose seedlings
This article answers questions about how to plant rose seedlings and provides information on the techniques and methods of rose seedling cultivation in the field of green plants and flowers. Here is a comprehensive introduction.
Roses belong to the Rosaceae family and have high economic and ornamental value. Rose flowers are bright in color and pleasant in fragrance, making them a famous raw material for essential oils with high value. Roses are treasures among ornamental flowers, widely cultivated in the country and favored by flower enthusiasts. They are also one of the main flowers for courtyard cultivation.
I. Propagation methods of roses
Propagating roses is easy. There are several methods:播种 (single-petal roses can be propagated by sowing seeds, which mature in October and can be sown immediately or stored in sand until March of the following year for sowing in autumn), division (done during the dormant period of roses), grafting, and cutting propagation. Usually, cutting propagation is adopted, where semi-woody branches are cut in June into 10-15 cm segments and planted in pots with sandy soil. After watering thoroughly and covering the pot with plastic film, roots can form in about a month under temperatures of 20-30°C. Once rooted, the cuttings should be transplanted promptly.
III. Preparing the growing medium, those with a courtyard usually opt for ground planting, while urban areas mainly use pot planting. The growing medium for roses should be loose, with good drainage and water retention. For pot-grown roses, the soil mix consists of 20-30% compost, 30-40% garden soil, and 30% wood ash.
IV. Planting roses, pot-grown roses are best planted in clay pots, usually using pots with a diameter of 27 cm or more. Planting is typically done in spring, autumn, or during the dormant period of roses. Place broken tiles at the bottom of the pot, then fill with growing medium. Place the rooted rose cutting in the center of the pot, making sure the roots are spread out. Fill the pot halfway with soil, then gently lift and shake the plant to settle the soil, and compact it. Do not plant too deep; the crown should be level with the pot opening. Planting too shallowly can affect survival, while planting too deeply can affect the plant's growth after transplanting. After planting, water thoroughly. Initially, keep the plant in a shaded area for a week, then move it to a sunny spot once the roots have recovered.
V. Water and fertilizer management, during the growth and development period, fertilize every 10-15 days. In dry weather, water every 1-2 days, and during hot summers and early autumn, water daily. Water moderately before blooming and empty the pot of accumulated water after rain. Especially in summer, insufficient water can cause leaf drop, so water in the morning and evening, and in autumn, water in the afternoon when the soil is dry. In winter, when the rose plant is dormant, control watering. Reduce watering after blooming, as excessive moisture can cause leaf drop and root rot.
VI. Pruning, after defoliation, prune heavily to thin out diseased, dead, and dense branches. For the remaining branches, cut strong ones by half and weak ones by two-thirds.
VII. Repotting, as roses grow vigorously and roots can quickly fill the entire pot, repot every 1-2 years. This is done in early spring before the roses start to sprout, removing old roots and adding new soil.
