[rose planting technique] the method of planting roses in the ground and potted roses

Generally speaking, the propagation of roses is mainly carried out by means of ramet, pressing and cutting. of course, they can also be propagated by sowing, but the rose seeds should be disinfected before sowing, and the survival rate is not as high as the above three.

The propagation mode of roses

Ramet propagation: one year before 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.

Striping propagation: in the plum rain season from June to August every year, select the sturdy branches of the same year, bend them into the soil, cut the part into the soil and embed them into the wound, bury them in the soil, fix them with bamboo forks or branches, let the tips of the branches expose the ground, keep the soil moist, take root in 2 to 3 months, and separate from the mother plant in the following spring and plant separately.

Cuttage propagation: before sprouting in early spring, one-year-old branches with strong growth and no diseases and insect pests were selected, cut into 20cm cuttings, and obliquely inserted into the cuttings made of Xinhe sand, with a depth of 12~14cm, compacted and watered, often keeping the temperature of the sand bed, rooting after about 30 days, and transplanting after germination.

Planting techniques of roses planted in the ground

Soil improvement: for alkaline soil, fully mature barnyard manure, compost, drug residue, grain husk, sawdust and other materials should be applied to improve the soil; plant ash and lime can be used to neutralize the slightly acidic soil to improve the soil; the depth of improved soil layer should be more than 40 meters. 1.3 meters per ridge, the width of the border is 60 meters, the height of the border is 30-40 meters, and the width of the ditch is 40-50 meters, which requires the border to be smooth.

Planting: it should be planted from March to April, and the flowers usually begin to produce flowers 6 months after planting. There are 2 rows in each bed, the plant spacing is 15 to 25 square meters, and the row spacing is 40 feet. When planting, the root system of the plant should be scattered around, and the grafting interface should be 1 ~ 2 meters higher than that of the topsoil.

Field management: summer heat prevention and cooling, ventilation and moisture drainage, timely drought and drainage, frequent application of thin fertilizer, strengthening pest control, pruning management according to non-flowering period, branch protection and leaf protection. Strengthen fertilizer and water management in autumn, promote plant growth, transfer to pruning management in flowering period, and promote flower branch germination. Close the greenhouse in winter, keep warm and moisturize, in order to improve the yield and quality of cut rose flowers, at the same time, pay attention to weather changes, timely ventilation.

Planting techniques of potted roses

On the basin: every spring or autumn can be on the basin, planting so that the root system stretch, on the basin after the soil should be compacted, soil from the edge of the basin 3 to 4 meters, the first time water must be thoroughly watered.

Peacetime management: rose like sunshine, more cold-resistant, drought-resistant. Flowerpots should be placed in a ventilated, breathable and sunny place, and the principle of watering is to see dry and wet. Rose afraid of waterlogging, afraid of stagnant water, for a little longer, the lower leaves will turn yellow and fall off, and will die in serious cases. At ordinary times, you can also carry out topdressing (such as bean cake water) or foliar spraying as needed.

Pruning: roses blossom on the branches of the year. Regular pruning can make the plant grow vigorously, the flowers are colorful, the aroma is stronger, the tree shape is correct, and the flowering life can be prolonged. Dormant pruning is carried out after defoliation in winter or before sprouting in early spring, cutting off dense branches, senescent branches, disease and insect branches, etc., the residual pile should not be too long when thinning branches, generally, the incision should be cut from the branch point and cut at a 45-degree angle, and the incision should be smooth. There are 4 to 5 branches per plant, cut short from 40 to 50 meters above the ground, 1 to 2 side branches per branch, and two buds on each side branch. Pruning during the growing period is carried out after the first batch of flowers bloom, cut short at about 15 to 20 meters above the base of the flower branches, and promote new branches, then the second flowering is more and of good quality.

Roses are a very good choice whether they are used to beautify the house, decorate open spaces such as home courtyards and balconies, or even as a gift of cut flowers, so if you happen to want to grow flowers, then roses can be added to the priority plants.
