Cuttings are a popular and sometimes the only possible way to propagate roses. In some varieties, cuttings do not take root very readily, so gardeners resort to the help of various preparations and folk remedies. Significantly increases the chances of obtaining new copies of Kornevin for roses. The biostimulant is considered safe for plants and humans, however, when using it, you must strictly follow the instructions and take all recommended precautions.

Description and release form

Kornevin is a universal auxin-type biostimulator used to activate the process of root formation during vegetative propagation of garden crops. It is used to treat ornamental and fruit-bearing, coniferous and deciduous plants, annuals and perennials.

Kornevin is used by amateur gardeners and in farming on an industrial scale.

Kornevin is produced in the form of a fine yellowish-gray-beige powder. Its active ingredient is indolylbutyric acid (also known as IBA, Seradix or Hormodin) at a concentration of 5 g per 1 kg. For personal plots, Kornevin is produced in small bags (4, 5, 10, 30 and 50 g), for large farms it is packaged in packages of 250, 500, 1000 g.

In addition to indolylbutyric acid, Kornevin also contains a complex of substances useful for roses and other garden crops:

Ascorbic acid. One of the most powerful natural antioxidants. Neutralizes pathogenic microflora and the negative effects of free radicals. In the future, it promotes abundant flowering of roses.
Thiamine. Kornevin activates the process of sap flow without accumulating in tissues. Helps roses obtain “energy” from carbohydrates, stimulating the process at the cellular level.
Oxygen. When the substrate is saturated, it activates the growth of green mass in cuttings.
Nitrogen. Participates in almost all metabolic processes. Vital for nourishing any tissue.
Potassium. Required for nutrition, protein and carbohydrate metabolism, and the formation of flower and leaf buds for the next season.
Phosphorus. Provides the plant with energy, participates in the metabolic process, activates the growth rate of the root system, and has a beneficial effect on the flowering of roses.
Manganese. One of the best natural antiseptics. Effectively destroys any pathogenic microflora that can infect rose cuttings.
Molybdenum. Participates in most metabolic processes and is necessary for the synthesis of chlorophyll and the absorption of vitamins. Kornevin affects the number, size of buds and the brightness of the color of the petals.

Important! The experience of gardeners shows that cuttings that have taken root after treatment with Kornevin subsequently take root in the flowerbed more quickly and react less “painfully” to any negative external influences.

Operating principle

Once in the soil, indolylbutyric acid in Kornevin is converted into heteroauxin, which has the following properties useful for cutting roses:

“help” in cell differentiation;
activation of metabolism and cell division;
stimulation of any growth processes;
beneficial effect in the future on the formation of leaf and flower buds;

Specifically, Kornevin’s “help” after processing rose cuttings is manifested in “irritation” of the integumentary tissues on the stems. As a result, callus grows on the resulting microdamages, reminiscent of “burns,” - connective tissue from “living” cells, from which root primordia are subsequently formed.

Indolylbutyric acid contained in Kornevin is a synthetic analogue of natural phytohormones from the auxin group

Advantages and disadvantages

The frequent use of Kornevin by gardeners, including for the treatment of rose cuttings, is due to the presence of a number of undoubted advantages in the drug:

versatility;
availability of several packaging options;
affordable price Kornevin;
compatibility with most insecticides, fungicides, fertilizers;
several processing methods provided for in the instructions;
complete safety for human health, the plants themselves and the environment in general, subject to the manufacturer’s recommendations;
activation of “dormant” buds, stimulation of the formation and development of the root system in roses, including varieties that do this “reluctantly”;
providing seedlings with high “stress resistance” after transplanting into a flower bed;
the presence of vitamins, macro- and microelements in the complex;
long-term (20-60 days) exposure after a single treatment of cuttings with Kornevin.

A powerful root system is a big plus for any plant

Of course, there are also some disadvantages:

the opposite effect with an “overdose” of Kornevin due to the high concentration of indolylbutyric acid;
lower efficiency of the aqueous solution compared to treatment with Kornevin powder in its “pure form” for cuttings of varieties that are difficult to root;
minimum shelf life of the finished solution, which quickly loses its properties;

Important! Kornevin’s specificity is his “narrow specialization”. The drug is not able to completely replace the fertilizers necessary for roses or protect them from diseases and pests, despite the increase in overall endurance.

Timing of cuttings of roses

The optimal time for harvesting rose cuttings is the end of May or the first half of June. It is advisable to cut them early in the morning, when the stem tissues are maximally saturated with moisture.

The cuttings must be “correct”, otherwise even Kornevin will not help them in the formation of the root system. The top or middle part of a shoot 12-20 cm long with 2-3 leaves on it is used. The upper cut is made straight, the lower cut is made oblique (to increase its area).

Before treatment with Kornevin, leaf plates are shortened by at least half or completely removed.

Important! Rose cuttings from bouquets can be rooted using Kornevin throughout the year. However, for better preservation, imported flowers are treated with preservatives that “kill” growth cells.

How to use Kornevin for rose cuttings

To root roses with Kornevin, it is used both in “pure” powder form and diluted with water. The instructions provide both options.

Application of Kornevin for rose cuttings in dry form

Using Kornevin powder for rose cuttings is extremely simple: “dry processing” takes no more than 2-3 minutes. The cut and lower part of the stems are lightly moistened with water and dipped into a container with Kornevin powder or thickly “powdered” with it, being sure to capture the lower bud.

Important! If the cuttings cannot be called freshly cut, the sections are renewed before treatment with powdered Kornevin.

After waiting a few minutes, shake off the excess. The cuttings are left to dry so that the Kornevin powder turns into a thin “crust.” After 2-4 hours, they are planted in separate containers at a slight angle, leaving the two upper buds on the surface. It is advisable to use a special soil for roses, but any loose “substrate” will do. The soil should be well moistened. Over the next 1.5-2 weeks, you will have to monitor its humidity level very carefully, preventing it from drying out.

Important! Since Kornevin is a fairly strong stimulant, when processing especially “capricious” roses, as well as rare exotic varieties, it is advisable to mix it in equal proportions with crushed activated carbon.

Before processing with Kornevin, it is advisable to make several longitudinal scratches on the stem with a needle or cuts with a scalpel or razor blade

Rooting rose cuttings in water with Kornevin

Before dipping in Kornevin, rose cuttings are “dried” in the open air for 2-3 hours. The fresher its solution, the better. It is prepared by diluting 1 g of powder in a liter of water at room temperature (25-27 ° C).It dissolves quickly and without residue in water - just vigorously stir the contents of the container for 2-3 minutes.

Rose cuttings are kept in Kornevin solution for 6-8 hours. Only the lower part of the stems should be in the liquid - the buds and leaves must remain on the surface.

Roses planted in a well-moistened substrate are moderately watered with the same Kornevin solution. When they give roots, after 3-5 days it is recommended to feed them with a complex specialized fertilizer for roses.

Important! The room where the roses are “aged” in Kornevin’s solution should be relatively cool (18-20 °C). If it is hot there or the cuttings are exposed to direct sunlight, the risk of rot will greatly increase.

For varieties that are difficult to root, it is recommended to use a mixture of drugs - Kornevin with Zircon or Epin

How to breed Kornevin for watering roses

For rose seedlings that already have roots, Kornevin is used when planting to provide them with faster adaptation to new living conditions, increased endurance and “stress resistance.” Immediately before planting, the hole prepared for the rose is spilled with Kornevin solution (1 g/l). It is also used to water the seedling after planting.

In total, 1.5-2.5 liters of liquid are consumed per rose (depending on its size)

Important! Kornevin can also be used to soak the roots of rose seedlings. In a solution of the same concentration, treatment takes 4-5 hours.

How to replace Kornevin for roses

The closest analogues of Kornevin used in processing rose cuttings are products based on phytohormones and other bioactive substances:

Heteroauxin. Essentially, a synthetic analogue of natural auxin in its “pure form”.
KorneStim, Root-Super.Drugs with absolutely the same composition, mechanism of action and instructions for use.
KorneRost, Athlete, Charkor. Products with a similar effect based on other bioactive substances.

Due to its high concentration, Heteroauxin provides the desired result faster

Adaptogen preparations (Zircon, Epin, Energen) can be considered partial substitutes for Kornevin when cutting roses. They do not contribute to the growth and development of roots, providing seedlings with mainly high “stress resistance”. They are used in a mixture with Kornevin. They will also be useful when planting already rooted cuttings and seedlings in a flowerbed.

There are also folk remedies to stimulate root formation. If using chemicals to treat rose cuttings is unacceptable for some reason, Kornevin can be replaced:

natural honey solution;
aloe juice;
fresh potatoes.

The effectiveness of potato juice as a biostimulant is explained by its high starch content

Precautionary measures

Kornevin is a drug of class III hazard. This means that it is not toxic to humans and pets. However, an individual allergic reaction or simply increased sensitivity to the chemical cannot be ruled out.

When treating roses with Kornevin, starting from the moment the solution is prepared, basic precautions must be observed, including:

prohibition on eating, drinking, smoking, using utensils intended for cooking, storing food, water;
availability of a minimum set of personal protective equipment;
shower and change of clothes at the end of the procedure.

Personal protective equipment reduces the risk of Kornevin getting on the skin and mucous membranes when processing roses

Important! If the powder or solution accidentally gets on the mucous membranes, eyes, nose, mouth, rinse thoroughly with cool water. Drinking liquid when treating roses with Kornevin requires gastric lavage and taking activated carbon or another sorbent.

Conclusion

Kornevin for roses, used when cutting them, significantly increases the chances of obtaining new specimens. The drug works not only as a biostimulator, activating the process of root formation from “dormant” cells. It also contains a complex of macro-, microelements and vitamins necessary for plants to develop normally. The product is quite easy to use, but it is important to strictly follow the instructions given by the manufacturer in the instructions.
