Raspberry pruning rules for beginners
Choosing a good raspberry variety is half the battle. In order for the raspberry to give a good harvest, it is necessary not only to choose the right place for it, carefully prepare the planting pits, but also to form these plants competently every year. What is raspberry pruning for? In order to prevent thickening, remove the shoots in time, rid raspberries of diseased plants, but the main thing is to get a good harvest. Indeed, the number of flower brushes laid down by the shoot, the size and even the taste of berries depends on how correctly and timely the pruning will be carried out, and this, you see, is the main purpose of planting it. Let's look at how to trim raspberries.

Pruning raspberry varieties for single fruiting
The simplest method of forming raspberries of one-time fruiting, but not the most effective, is spring shortening of shoots by 15-20 cm, with the simultaneous removal of shoots of the last year. Its advantage is simplicity and one-time care for raspberries, but this method has little effect on the crop.
However, this technique has an interpretation that allows you to stretch the collection of berries. It consists in shortening the shoots of raspberries at different heights. In some plants, the standard is 15-20 cm, in some 50% of the length, and in the rest, at a height of 15 cm above the ground. The meaning of this technique is as follows: the smaller the shortening, the earlier the crop will ripen. However, such pruning also does not affect the number of berries.
Raspberry Sobolev pruning
To increase yield, there is still a not very popular, but quite effective pruning method, which allows several times to increase the collection of berries from the same raspberry. It is called the Sobolev method.
Method A.G. Sobolev includes two stages of raspberry formation. Each of them is aimed at stimulating the formation of side branches, as a result of which an increase in yield occurs. Let's look at them.
Stage one. In the yard, the beginning of summer (June-July) is the time when raspberries bear fruit and massively grow young shoots. As soon as the shoot reaches a height of 80-120 cm, the moment comes to shorten it by 10-15 cm. This will provide an incentive for growth from the axillary buds of the main shoot of the side branches, which by the end of the growing season will grow to 30-40 cm.
Stage Two. Next year. Spring. Until the buds are awakened, it is necessary to shorten the raspberry shoots again, but now of the first order, coming from the main stem, and only 5 cm. This again will give an incentive to the formation of side shoots, but now of the second order. In this case, flower branches are formed on the shoots of the first, and on the shoots of the second order, which doubles the yield.
The raspberry shoot trimmed by Sobolev's technique visually resembles a branched tree. This shoot is allowed to bear fruit and, immediately, without waiting for the end of the growing season, is removed. Early pruning of last year's shoots provides the release of nutrients for the new shoots, increases the illumination and purge of bushes, which means raspberry health.
Pruning Raspberry Repairing Varieties
For repair varieties, there are also several pruning techniques.
Option one. More often it is used in the middle lane and to the north and consists in the complete removal, together with the young shoots, in autumn or spring, of the raspberry bush that has prolapsed. It is believed that this technique increases the quantity and quality of berries of the next fall season, but because of it the summer crop is lost.
Second option. After the summer harvest, the raspberry shoots that are bred from the biennial shoots are immediately removed. Young shoots are left for autumn fruiting and fruiting next year.
In addition to these techniques, there are several more, on which the health of raspberry plantings depends to a greater extent, which, however, also affects the yield.
Thinning raspberry pruning
Thickened raspberry bushes experience a lack of light, a lack of nutrition, and a lack of ventilation, which provokes not only the formation of smaller berries in smaller quantities, but also weakening of plants in general, increases the risk of planting morbidity. Therefore, in the spring, and then, as new shoots sprout in the raspberry, it is necessary to regulate the load on the bush.
For this, each bush is inspected, highlighting 4-7, depending on the growth potential of the variety and planting method, well-formed shoots, and the rest is removed. If raspberries are tied to the trellis, shoots are placed at a distance of at least 10 cm from each other. Therefore, the number of shoots is considered based on the possibility of their location.
Sanitary pruning raspberries
And finally, sanitary pruning raspberries. It is carried out in the early spring, and during the summer, and in the fall.
After the snow melts, it consists in the removal of frozen and broken shoots. During the growing season - in the removal of shoots affected by diseases (curls) and pests (raspberry stem gall midge, raspberry stem fly, raspberry bud moth).
In autumn, it consists in removing the raspberry shoots that have bereaved, if this was not done immediately after fruiting. At the same time, in the shelter zones, the shoots are grouped and lean to the ground.
General rules for pruning raspberries
No matter what time of year or whatever raspberry variety you cut, there are general rules for pruning this plant to help make the process as effective and safe as possible for the crop.
- Pruning raspberries is best done on a dry sunny day.
- Use a well-sharpened, sanitized secateurs for trimming.
- After pruning diseased plants, the secateurs must be disinfected (with kerosene, alcohol).
- The cut should be perpendicular to the ground, without a “sail” (sticking up strips of bark).
- When pruning under the root, hemp does not leave raspberries, since the remains of the stem left above the ground are a place for the development of pathogens and pests.
