Cuttings of roses
There is probably no flower more popular than roses. She is the constant companion of birthdays and anniversaries, weddings and school holidays, gala performances and touching confessions. That is why many amateur gardeners are happy to turn rose hobbies into a major source of income.
There are many technologies for breeding roses, however, one of the simplest and most popular is cuttings. This method allows you to grow root rosesthat have recently become a real rarity. As a result, cuttings can be successfully bred both “for oneself” and for sale. In this case, the sale of rooted cuttings and seedlings can be carried out not only in parallel with the sale of flowers, but also separately, as an independent business, bringing a very good income.
Green cuttings are best done in April-May (in the greenhouse) and in June-July (in the open ground), when buds are painted on the uterine bushes. For cuttings, annual semi-lignified shoots of 5-6 mm in diameter are suitable. The middle part of the shoot is cut into cuttings 5-9 cm long so that 2-4 kidneys remain on each. An inclined section is made under the kidney itself, and a straight upper one is 5 mm above the kidney. In order to reduce moisture evaporation, the upper leaves are shortened by half, and the lower ones are removed. Next, the lower ends of the cuttings for a day are placed in water or a heteroauxin solution (40–45 mg of dry matter are taken per 1 liter of water), which increases rooting and accelerates root formation.
Root cuttings can be in boxes, hotbeds, in closed ground and even in pots under banks. For planting, a mixture of sand, turf and leafy soil (2: 2: 1) is prepared, which covers the bottom by 5 - 9 cm. A layer of coarse sand (3 - 4 cm) is poured on top. Sand can be mixed with vermiculite or peat (in equal parts). The prepared substrate is treated with a weak solution of potassium permanganate. Cuttings are planted at an angle of 1.7 to 2 cm at a slope. Moreover, they should be at a distance of 3 - 6 cm from each other, and rows should be at a distance of 8 - 10 cm.
Cuttings are best rooted at an air temperature of 22 - 25 ° C and soil temperature 1 to 3 degrees higher. At the same time, air humidity should be maintained at a level of 90 - 100%, for which either a mist-forming plant or multiple spraying of leaves with water is used (about five times in hot weather and two or three times on cloudy days). Rooting occurs on day 15-25, after which the number of sprays should be reduced and ventilation should be intensified.
"Greenhouse" cuttings are planted for growing in open ground in early summer. “Summer” cuttings are left in the greenhouse for the winter at an initial temperature of 6 - 8 ° C, and then at 18 - 20 ° C. Thus, by spring you can get fully developed plants that are planted in open ground at the end of May.
In addition to green ones, woody cuttings are also used. To do this, during autumn pruning of roses, shoots suitable for cuttings are selected, leaves are removed from them and stored in wet sand or peat until spring. Next, cuttings are cut from shoots with a length of 10-15 cm, while the oblique lower cut should be under the kidney, and the straight upper cut should be 3-5 mm higher than the kidney. Cuttings are planted in April – May so that only the upper bud remains above the surface of the soil. The soil is covered with a film, and as the soil dries, watering is done. Some cuttings are rooted in the summer, and the remaining - closer to the fall.
