The propagation of roses
fissiparity
Before 1 plant division, sufficient fertilizer and water should be applied near the rhizosphere of the mother plant, and at the same time, the soil should be kept loose and moist to promote a large number of tillers in the roots. Because of the strong tillering ability of rose, the mother branch is easy to wither after each new branch is drawn, so it is necessary to transplant the branches near the rhizosphere to other places in time so that the mother branch can still grow vigorously. Therefore, from 1 1 to 12 every year, after the leaves fall, or when the buds just germinate in February of the following year, new plants that grow vigorously next to the mother plant can be dug up from Dahuadun, with 2-3 stems per cluster and planted separately with roots. After planting, cut it from 20 ~ 25 cm above the soil surface, cultivate it for 2 ~ 3 years, and blossom in clusters.
Stratified propagation
In the rainy season from June to August every year, select the robust branches of that year, bend them into the soil, carve out the embedded parts, embed them into the wound with clods, bury them in the soil, fix them with bamboo forks or branches, make the branches exposed from the ground, keep the soil moist, take root in 2-3 months, and plant them independently in the next spring.
cutting
Before germination in early spring, select robust and pest-free 1 annual branches, cut them into cuttings about 20 cm long, obliquely insert them in the sand bed of Xinhe River with a depth of 12 ~ 14 cm, compact them, water them, keep the sand bed at a constant temperature, take root about 30 days, and transplant them after germination. Sand bed cutting is easy to heal and take root, but it needs to be cut in the sunny place of greenhouse or in the field with arched plastic shed and careful management. Softwood cutting is usually carried out in rainy season. Take semi-mature branches, cut about 20cm in the middle and lower part as cuttings, with 2 ~ 3 nodes and buds on them, insert them obliquely in the soil, water them after compaction, and transplant them after rooting and sprouting. Cutting of old branches is mostly carried out in the growing season from September to165438+1October.
Water roses regularly in summer. Roses that grow well need a lot of water. Don't let the soil dry completely. If you see dust on the ground, it means that there is no water. For the transplanted flowers, choose the watering frequency according to the situation in your area, usually you need to water them thoroughly once a week.
