That is, in the spring cold he is not threatened. By current standards, its yield is average. From one bush, you can collect about four to six kilograms of the crop. But if you provide the plant with all the necessary care and comfortable conditions, then you can achieve an indicator of ten kilograms.

In order to get the harvest of the desired level from a real varietal variety, you need to adhere to some agrotechnical rules. This variety is planted only in areas with sufficient sunlight. Also, before planting it, the landing pit is stratified without fail. After planting, it is necessary to develop the correct watering regime, mulch the bush in a timely manner and carry out pruning. Preventive treatments against possible diseases and insect pests are also important.

What should be the composition of the earth-mixture.

Rochefort grapes do not have special requirements in relation to the soil. But it must be borne in mind that if you plant a bush on sandy soil, then you will definitely need fertilizers and top dressing. If there is no fertilization and feeding, then the bush will develop poorly.

Suitable place for planting.

The site must be sunny so that the bush receives a sufficient level of lighting. If you want to plant a culture near someone's structure, or a fence, then it is recommended to choose the side with the south or southwest direction.Also, this bush does not like cold drafts and strong gusts of wind, that is, it needs protection. Also, groundwater should not lie less than two hundred centimeters.

About planting in the autumn.

Planting of this type is carried out on the twentieth of the second month of the autumn period. In order for the plant to subsequently endure the winter cold, it will need additional shelter.

About planting in the spring.

Planting in the spring is most effective. Indeed, at this time, the bush has all the conditions for quick adaptation and rooting. There are several guidelines.

In the spring, it is customary to plant those seedlings that have been prepared since the fall. If there is a dormant rootstock on the acoustics, then you can try to graft cuttings to it.
If the selected bush has already released greenish shoots, then it will be possible to plant it only when the soil is finally warmed up and the temperature regime becomes stable.
A few weeks before the planting event, you need to prepare the planting pit. Its depth should be about eighty centimeters.
On one landing hole, it is necessary to pour a layer of soil, which is rich in trace elements, macronutrients, as well as nutrients. Then add ten to twenty kilograms of organic fertilizing, then add the nutrient soil again.
The selected seedling must be very carefully placed in the planting hole, lightly sprinkled with soil and supported.
After you have fixed the seedling, you need to water it. Irrigation water should be clean, filtered, and at room temperature.

Watering rules for Rochefort grapes

Rochefort grapes need abundant watering when it passes the growing season, and ovaries are also forming.

This variety has three periods when it needs frequent and abundant watering. These are: 1) when the bush begins to bloom its buds., 2) after the bush has bloomed., 3) when it has a time of active ripening.
When the bush is in bloom, it does not need to be watered. This is necessary in order to reduce the risk of inflorescence falling off.

The importance of mulching.

It is necessary to mulch the bush. This will help in maintaining the desired percentage of moisture, as well as protecting against weeds. Dried straw or sawdust can be used as a mulching material. Mulching is very important for cultivation in the southern regions. In other regions, you need to be careful with mulching, as you can achieve hypothermia of the plant's root system.

Pruning Rochefort grapes

Consider autumn pruning.

The pruning procedure should be carried out in the autumn and spring.
On one bush, you need to leave about thirty to thirty-five buds.
On each grape shoot, you need to leave up to six to eight eyes.
Pruning in the fall is very important to do before the first frost.
After pruning in the fall, cover the plants for subsequent wintering.

Consider spring pruning.

Spring pruning must be done in order for the sap flow to begin at the bush.

Rochefort grapes: protection against diseases and pests of the variety

Powdery mildew

The Rochefort grape variety has an average level of resistance to fungal infections. These bushes are very often affected by a disease such as powdery mildew.

How powdery mildew behaves.

Fungal spores of this disease very easily penetrate the inside of the leaf plate to try with cell sap. The disease very quickly moves to inflorescences, shoots, and bush stems. It is very important to start treating a given disease as soon as you discover its symptoms. Spores of this disease develop very quickly at a high percentage of humidity. In the presence of powdery mildew, the leaf plates of the bush are covered with a grayish-whitish bloom. Due to powdery mildew, the bush can lose its berries, inflorescences, and foliage. Also, if the plant gets sick while the berries ripen, the fruits will begin to crack and then rot.

How can you deal with powdery mildew.

It is very important to know that when the fruits ripen, the plant cannot be treated with chemicals. Sulfur is recommended. After all, the northern elements perfectly destroy fungal spores. Spraying can be done early in the morning or in the evening. You need to repeat the procedure every fifteen to twenty days.

In order to combat powdery mildew, a solution can be made. To do this, you will need to dilute one hundred grams of sulfur in ten liters of clean water at room temperature.

Preventive measures.

For prevention purposes, you can use a sulfuric solution. To make it, you will need to dilute thirty grams of sulfur in ten liters of water. You can also use fungicidal preparations. For example, such as: 1) ridomil., 2) vectra., 3) copper sulfate., 4) iron vitriol., 5) Bordeaux liquid. When working with chemicals, it is very important to pick up the dosage, safety precautions and act strictly according to the attached instructions.

Phylloxera

The grape bush of this variety is vulnerable to such a pest insect as phylloxera.

What is the phylloxera insect pest?

This is a very small insect. The size of an adult can reach one millimeter. And the larva, can reach half a millimeter in its size, prefers to eat the root system, leaf plates, as well as bush shoots.
When the air warms up to one degree of heat, then this insect begins its life cycle. It lasts until the end of the autumn period.
You can understand that a pest has attacked a bush by the appearance of small tubercles and tumors on the root system of the plant.
After his attack, the root system of the plant is very badly damaged. Because of this, the entire bush may die. Unfortunately, the bush cannot be brought back to life and somehow cured. Therefore, it only needs to be destroyed. It is also important to know that in the area where the plant grew, it will not be possible to plant for the next ten years.
