Cutting of decorative garden roses is the simplest and most affordable way, allowing you to independently propagate and grow your favorite variety. It is not too difficult to propagate and grow roses from the cuttings, but it is best to use such breeding if necessary to obtain a weaving, miniature, groundcover rose. It is somewhat more difficult to cut and independently cultivate scrubs, grandiflora and some Dutch varieties of tea-hybrid roses in this way.
Cuttings are of several types: green cuttings, lignified and root. Each of them has its own characteristics.
Features of the cuttings of roses
The optimal timing for correctly propagating the roses is represented by the period from the formation of a full-fledged bud until the petals fall from the inflorescences. Cutting a decorative culture at an earlier date is not desirable, as making wood can be unripe. Growing roses from cuttings harvested at a later date is also not recommended, because it is during this period that the awakening of the buds is observed, and the plant may not have enough strength to form the root system.
Many experienced amateur gardeners advise giving preference to autumn cuttings, which is due to the preparation of the plant for winter rest and maximum accumulation of nutrients. Among other things, it is when trimming and preparing a decorative culture for wintering that there is a great opportunity to choose the most suitable and high-quality planting material.
Preparation of semi-lignified cuttings
The preparation of semi-lignified rose cuttings should be carried out with extremely healthy and well-developed plants, using the middle part of the shoot. The standard thickness of the quality cuttings should be approximately 4-6 mm. Planting material should be cut at the stage of active budding, when the base of the shoot only begins to lignify and a very characteristic crack is observed during folding.
The rooting of cuttings obtained from long shoots with buds or flowers is somewhat worse. Unsuitable for grafting are young and green, not fully ripened shoots, as well as the apical part of shoots with buds.

Harvesting lignified cuttings
At the stage of preparation of adult rose bushes for winter frosts, the apical part of the shoots is cut off, which allows us to prepare a sufficient amount of high-quality planting material.
The method of grafting in this case is as follows:
- shoots from the mother plant are suitable for cuttings, which are no thicker than a pencil, which will ensure optimal planting survival of planting material;
- all cuts and preparation of cuttings should be carried out previously well-sharpened and disinfected with an alcohol solution and boiling water with a garden tool;
- high-quality, suitable for propagation of decorative culture planting material should have about three to five developed buds;
- all cuts on the shoots must be performed at a right angle from above and at an oblique angle in the lower part.
It is preferable to plant the cuttings directly at a constant place of cultivation, which is a less traumatic way of cultivating roses in a home garden.
Cuttings of roses may be required for the propagation of decorative culture through vaccination. This method involves the use of wild rose as a stock, and compliance with the following technology:
- the vaccination is carried out in the basal part of the dogrose;
- on a stock using a sharp knife you need to make a pair of oblique slices and a small "tongue";
- the harvested stalk is inserted into the cut;
- the place of vaccination is carefully fixed with electrical tape, adhesive tape or polyethylene.
After a few weeks, the slices begin to grow together at temperatures above 12-14aboutC. The complete process of growing together a rose stalk with a stock takes about a month and a half, after which the fixing winding can be removed.
The use of modern and highly effective growth stimulants helps to accelerate the rooting process and significantly improves the survival rate of harvested cuttings.
- The following solutions and formulations are recommended as stimulants:
- a solution based on "Heteroauxin" diluted at the rate of 10-20 g for each liter of water;
- a solution based on "Kornevin", diluted at the rate of 15-30 g per liter of water;
- a solution based on "Naphthylacetic acid", diluted at the rate of 10-20 g per liter of water;
- a solution based on "Epin", diluted at the rate of 0.25 ml in a liter of water;
- solution based on "Zircon", diluted at the rate of 0.1 mg per liter of water.
Special preparations can be replaced with aloe juice or honey, which must be diluted in warm water. The lower cut of the cuttings must be immersed in the prepared solution for several hours or for a day. Processing time is indicated by the manufacturer on the packaging of the stimulant.
There are many ways to cut roses. Each rose grower prefers the method that seems to him the most simple and effective.
In the process of preparing the cuttings, a potassium permanganate solution is processedthen leave the planting material in a solution based on aloe juice for about twelve hours. Medium-sized potatoes should be washed and dried, and then all eyes should be carefully removed. Potatoes with shanks immersed in it must be installed in a dark place and covered with a glass jar, which will create a greenhouse effect. Watering is carried out once a week, and after the emergence of the roots can completely remove the can shelter.
This option does not guarantee absolute rooting, and the yield of high-quality planting material is negligible, so it is more suitable for experimenters and gambling gardeners.
The method of cuttings in the newspaper according to the Burrito method is not very popular among domestic flower growers, but it is very simple. The lower part of the cuttings should be treated with the Kornevin or Epin stimulant, then wrapped in a moistened newspaper and placed for a couple of weeks in a dark place, subject to a temperature regime of 15-18 ° C until the roots appear.
By Trannoy's method
This method of planting "under the bottle" is carried out quite often. In mid-summer, shoots should be selected, the length of which is suitable for cuttings. From such shoots, cuttings with a length of 20-25 cm need to be cut, then remove everything except the upper pair of leaves. Planting of cuttings is carried out immediately to a permanent place. The plot should be sunny.
You need to plant the cuttings at an angle of 45 °, after which the planting material should be covered with plastic bottles or use a glass jar for this purpose. If several cuttings were planted in each landing hole, then after rooting they must be planted in separate pits. Planted rose cuttings must be regularly watered, and it is also necessary to loosen the soil, which will improve the flow of oxygen to the root system of the plant.
Landing on a permanent place and care
Planting the stalk in a permanent place is best in the spring. Before planting a young plant, you should choose the right place and prepare it for planting. The soil must first be dug up to a depth of 30-40 cm. A standard amount of peat and coarse sand must be added to the areas represented by loamy soils.
In the presence of poor podzolic soils, they are enriched with well-rotted organic fertilizers. On sandstones, it will be necessary to make turf land with the addition of humus and peat. A good result is the introduction of a glass of wood ash, 30 g of potassium salt and 25 g of superphosphate. In the open ground or in the greenhouse, prepare well holes in advance. After planting, plants need to be provided with abundant watering, and if necessary, shade seedlings from the scorching sun. It is necessary to water the rooted cuttings with warm, well-maintained water.
Storage of cuttings in winter
After cutting for cuttings, all the shoots need to be carefully divided into varieties and freed from leaves, then bundled and signed. Many flower growers recommend digging up planting material for preservation in winter in pre-harvested, high enough, with good drainage of the ridge. To prevent the ingress of moisture to the planting material as a result of snow melting, it is recommended to cover the ridges with fir spruce branches, on top of which roofing material or plastic film is stretched.

However, according to experts, the best conditions for storing cuttings throughout the winter period is a dry and well-ventilated basement or cellar. The optimum temperature is at a level of 1-3 ° C with indicators of air humidity in the range of 65-70%. A small amount of planting material can be stored on the bottom shelf of the refrigerator. As a rule, in the first year, the harvested and sprouted cuttings of the rose still have a rather weak and shallow root system, which involves growing and only subsequent planting in a permanent place.
