Propagation methods of roses

Rose planting is often based on ramet propagation, but it can also be propagated by pressing and cutting. here we briefly introduce these three ways of propagation.

Ramet propagation

One year before the ramet, it is necessary to apply enough fertilizer and water near the rhizosphere of the mother plant, keep the soil loose and moist, and promote a large number of roots to sprout. Because the rose has a strong tillering ability, the mother branch is easy to wither after each new branch, so the shoots near the rhizosphere must be transplanted to other places in time, so that the mother branch can still grow vigorously. Therefore, from November to December every year, after the defoliation of the plant, or when the bud just sprouts in February of the following year, new plants with strong growth next to the mother plant can be dug from the big flower stump, with 2 or 3 stems in each cluster, and planted separately with roots. After planting, the stem was cut off from the 20~25cm above the soil surface and cultivated for 2-3 years to blossom in clusters.

Striping propagation

During the plum rain season from June to August every year, the sturdy branches of the same year are selected and bent into the soil. After being cut into the soil, the soil is embedded in the wound and fixed with a bamboo fork or tree branch, so that the tip of the branch is exposed to the ground and keep the soil moist. It can take root in 2 to 3 months, and can be separated from the mother plant in the next spring and planted separately.

Cuttage propagation

Before sprouting in early spring, one-year-old branches with strong growth and no diseases and insect pests were selected and cut into cuttings with left and right length of 20cm, which were obliquely inserted into the cuttings made of Xinhe sand, with the depth of 12~14cm, compacted and watered, often keeping the temperature of the sand bed, rooting after about 30 days, and transplanting after germination. It is easy for sand bed cutting to heal and take root, but it needs to be cut in the sunny part of the greenhouse or in the field, and the management work should be meticulous. Softwood cuttings are generally carried out in the rainy season, taking semi-mature branches, cutting about 20cm as cuttings, with 2-3 nodes and buds on top, oblique in the soil, compacting and watering, and transplanting after rooting and sprouting; old branches cuttings are mostly carried out in the growing season from September to November.
