Propagation by cuttings of roses.
Methods of breeding roses, there are many. But for most amateur floriculture fits very simple and reliable way - cuttings of roses. Rooting of cuttings can be carried in a container with water or in a pot with soil.
Cutting cuttings produce better escape before flowering roses when buds occurred staining (not later) When cutting cuttings at a later date the percentage of rooting is reduced and rooting itself takes longer.
Is the method of breeding roses from cuttings in the following: bush cut escape, and then from the middle portion cut cuttings with three kidneys. Here, by cutting the bottom kidney make an oblique cut (45 degrees) and over the top of the kidney - straight cut. Basal leaf cuttings are removed completely, while the upper leaves are pruned to 1.3 surface.
Rooting cuttings of roses in water.
Cuttings of roses set in the water and put it in partial shade, in a warm greenhouse. Used utensils and water should be clean. Water is better to take prokipyachÑ‘nnuyu: the raw water many pathogenic fungi, and in the rain - blue-green algae, which multiply rapidly. All care cuttings of roses is to add and change the water.
After 20-30 days, when the cuttings of roses appear roots, they are taken up in pots with fertile soil. Winter rooted cuttings of roses keep on the windowsill in the room (taking care of them is the same as when you save yearlings own-rooted roses).
This method of rooting cuttings of roses has a disadvantage - for the formation of roots in cuttings in water is not enough oxygen. For example, the rose varieties Flamentants this way I could not multiply all her cuttings rotted. Rooting cuttings in a pot of soil and sand passes more successfully.
Rooting cuttings of roses in the soil.
With a small number of cuttings rooting climbing roses can be potted. To do this, cut stalks of roses planted in pots with fertile soil. To stalk roses do not rot in the center filled with a substrate of the pot to do the indentation (with the help of thick sticks) and pour into the recess coarse washed river sand. In this sand and need to plant prepared stalk of rose, it does not touch the bottom of the fertile soil.
Planted stalk gently pour a glass jar and cover, painted with latex paint. Prerequisite for rooting roses - long daylight hours and a sufficient amount of soft light (hence the glass banks teplichku should be painted or covered with a cloth svetopronikayuschey); pots with rooting cuttings of roses in the shadow set is not necessary.
Optimal for rooting roses temperature - 23-25 â€‹â€‹degrees. Pour cuttings as needed. After the start of the growth of young shoots of roses begin to gradually lifts the jar. But removed from the cutting bank can finally only after when you are sure that the plant has a rather long roots.
It is best to take root cuttings of roses, if possible during the day every half hour to spray water leaves the cuttings. Water spray should be fine atomization. Manual spraying numerous rooting cuttings of roses is quite time-consuming. This operation can be automated using various automatic misting system. But they are expensive and profitable only for large volumes of rooting.
Automatic misting systems can operate on two principles:
- On a "dry-wet leaf" when there is a disconnection or contact closure, depending on the humidity of leaves;
- With the use of a programmable timer, when there is no "snap" to the leaf wetness.
Both of these principles work systems have both advantages and disadvantages.
