We learn all the subtleties of vegetative reproduction with the help of a phytostimulator Kornevin

The content of the article:


A beautiful, healthy and successfully fruit bearing plant is distinguished primarily by a developed root system. In the vegetative mode of propagation cuttings do not take root primarily due to weak root formation, and biostimulants can help them in this. Kornevin is one of the most popular drugs, containing in its composition all that is necessary for building up the root mass. To ensure that it benefits and does not harm, before using you need to learn all the subtleties of the application.

Description of the root and its effect on plants

Kornevin is a root growth stimulant, an improved analog of all known heteroauxin. Its action is based on the irritation of the plant cover tissues, resulting in the formation of callus cells (an incision in the cut or fracture of the cuttings or leaf) and roots.

This effect has indolyl-butyric acid (IMC). Getting into the soil, it is converted into a natural hormone of the root formation of heteroauxin. This drug differs from its predecessor by a longer action.

The composition of the rootstock, apart from IMC, includes macro- and microelements, which promote root formation-potassium, phosphorus, manganese and molybdenum.

The drug is available in packs of 4, 5, 10, 125 and 250 g and is a cream colored powder. Apply it in both dry and liquid form.

The stimulator has the following action:

  • promotes rapid and friendly germination of seeds;
  • stimulates the formation of the root system in cuttings;
  • reduces stress and improves the survival of seedlings and seedlings;
  • increases the resistance of plants to unfavorable natural factors - lack or excess of moisture in the soil, sharp temperature changes.

All this does not mean that the plant treated with corn root will not be exposed to pests and diseases. It does not replace fertilizing with organic or mineral fertilizers, but only contributes to the development of a powerful root system, which is the basis of the very existence of the plant. On the photo below: on the right root system of the cuttings, which was treated with corn root, on the left - a control sample.

How to use the product according to the instructions

The root-maker is able to benefit only with proper use. To do this, follow the instructions for using the root. To prepare workers with a solution, only clay, enamel or glassware is used.

When used in a dry form, the cuttings are dipped in powder and after a while lowered into water or immediately buried in the ground. Cuttings, sliced ​​for vaccination, are also recommended to powder the rootstock.

Experienced gardeners are advised to mix the drug with any fungicide in a ratio of 10 to 1. Such an additive activates the plant's immunity and protects the sections from fungal damage.

To prepare the solution for 1 liter of warm water, take 1 gram of powder. The resulting substance is well mixed and immediately used. Tubers and bulbs are soaked in the working solution for 20 hours, as much as it is possible to soak in the root and seeds. Then the treated planting material is planted in the ground. For better survival of seedlings, the wells are spilled first with clean water, and then with root solution. Then plant the seedlings, compact the soil and water the root former once more. When watering the following recommendations:

  • 2-3 liters for seedlings of trees and large shrubs;
  • , l for low and medium shrubs;
  • 40-50 ml for flower and vegetable seedlings.

Before planting seedlings of apple, plum, pear, cherry, quince, cherry, the roots are kept in a solution of corn root for 10-12 hours. Add 1 teaspoon of powder to a liter of water.

The opened packaging is used immediately. The remaining powder should be poured into a tightly tight container. The aqueous solution is not subject to storage.

Application for seedlings

Instructions for the use of rootstock for seedlings include keeping the seeds in an aqueous solution for two hours. Cultures that do not tolerate root damage are poured by the stimulator during picking and two weeks after it. In order not to harm the sprouts, you need to know how to properly dilute the root for watering the seedlings. The working solution is prepared from the calculation of 1 g of the preparation per 1 liter of water. One plant requires no more than 60 ml of a liquid. Overdose causes inhibition of seedling growth, so the seedlings are watered, carefully measuring the amount per each bush.

When transplanting grown seedlings into the ground should be guided by the weather. On sunny and warm days the preparation is useless to use, since additional stimulation of the root formation will stop the growth of the aerial part and slow the beginning of fruiting. Favorable weather conditions themselves contribute to the development of the root system and the further growth of the plant. More useful will be the use of rootstock for seedlings in a protracted cold spring, when the earth is slightly warmed by the sun. Sprouts at this time spend a lot of energy on overcoming unfavorable conditions and transplanting into the soil is painful. To help young plants take root and maintain strength, use a biostimulator. The powder solution is prepared according to the standard scheme described on the package.


Each bush is watered individually, under the root, so as not to cause rapid growth of weeds.

Also, the roots of the seedlings are kept in the working solution for several hours immediately before planting into the soil. If the seedlings are well rooted and actively went into growth, more corms do not use.

Root for indoor plants

Instructions for the use of the root for indoor plants suggests several options for its use:

  • soaking seeds in an aqueous solution for 2-3 hours;
  • cutting of slices of cuttings or leaves;
  • keeping cuttings in one solution.

If the rootstock is used in dry form, cut the cuttings with water and dipped in powder. Then the excess of the drug is shaken off, and the stalk is planted in the ground or a flower pot. Some plants are better sucked, if they are kept in the solution of the stimulant before the appearance of rootlets.

Kornevin is used if cyclamen, orchid or gloxinia perish from incorrect care. Before sending gloxinia or cyclamen to forcible rest, cut off all damaged and decayed roots. The remaining healthy roots before the transplant are kept in the working solution for several hours.

Kornevin is able to save an orchid with a decayed root. All the diseased roots are excised, then the flower is kept in the dark for two hours at a temperature of about 27 ° C. This procedure helps the slices dry and do not rotate again. Prepare a fresh solution of the root, place the orchid in it and keep it in a warm room until the formation of new roots.

Rooting cuttings of grapes

To root the cuttings of the grapes, the rootstocks are used both in dry form and diluted in water. This crop propagates quite easily with cuttings, but if the planting material is very small or a particularly valuable variety, it is worthwhile to reinsure and use the root-former.

The dry method is more reliable, it will require a higher consumption of powder and is dangerous for the rotting of the cuttings. It is used if the selected variety does not take root in the solution. The dry method is used if, after 2 weeks of rooting, no callus formation has occurred in the solution. The stalk should be carefully examined under a magnifying glass: if at least microscopic sagging is noticeable, it should be left in an aqueous solution.

How to root a rose from a bouquet with the help of a root

Sometimes on the stems of a rose from a bouquet, green buds are formed on the place of dangling leaves. If you liked the variety, it is worth trying to root the stalk. For this, the stem is cut at the bottom and at the top, leaving 3 healthy swollen buds.

The lower part of the stem from the cut to the lowest kidney is scratched with a sharp knife to make it easier for the roots to germinate. Then this place, including the cut and the lower bud, is dipped in the rootstock, and after a few minutes the excess is shaken off and the stalk is planted in the planting tank. The upper two kidneys should remain on the surface. It is advisable to use a special primer for roses.

From above the container is covered with polyethylene or covered with a transparent plastic glass and placed in a warm bright place. From time to time shelter is removed for ventilation and, if necessary, moistens the earth.

For rooting roses experts recommend using a rootstock along with zircon.

If live cuttings from the bouquet still remain, they can be tried to root in the aqueous solution of the drug. Planting material is prepared in the same way as for rooting in a dry way. Only the lower kidney of the cut should remain in the water.

Rules for the treatment of corn root

The drug belongs to the 3rd class of danger, and you need to work with it in gloves, and the used packaging should not be thrown away, but burned. The manufacturer of the stimulant prescribes the following precautions when handling:

  • the drug is not diluted in food containers;
  • Do not eat, smoke or drink while working;
  • In case of contact with hands, wash immediately with soap and water;
  • if you accidentally swallow even microscopic doses, drink plenty of water, induce vomiting and take activated charcoal;
  • the drug is stored in places inaccessible to children.

All components of the root are not phytotoxic and are not carcinogens, but recommendations should not be neglected.

Using rootstocks allows not only to get healthy strong plants with a powerful root system, but also to achieve the rooting of the most unusual and exotic cultures on their site. With its help it is also easier to learn how to plant different varieties and get strong viable scions.
