Raspberry pruning: proper care in different seasons
In almost every garden in our country, a thorny shrub grows, which gives sweet, juicy, fragrant raspberries. Gardeners love this plant because it does not require special care, while the harvest is always pleasing. However, even some raspberry care activities still need to be carried out. In particular, the bushes need to be trimmed regularly.
What is it for?
It is a mistake to believe that the more stems a raspberry has, the more berries there will be. Quite the contrary: on one small but well-groomed bush, much more crops will ripen than in impenetrable thorny thickets. In addition, dense vegetation does not allow the berries to fully ripen, since numerous stems and leaves cover the fruits from sunlight and optimal air flow. While proper ventilation of all parts of the shrub plays a significant role in its growth and development. Also, timely pruning of the plant helps to cure and prevent the occurrence of diseases, the spread of pests. In addition, picking berries will become much easier. Yes, and a well-groomed shrub on your garden plot will look much better.
When it comes to raspberry varieties, the inflorescences of which are formed on two-year-old shoots, then pruning is required, since the untimely removal of old branches leads to the fact that young flowers simply have nowhere to spread. The new crop simply will not be able to ripen.
The absence of berries does not always indicate that you have chosen a bad raspberry variety or planted it incorrectly. Often, it is the improper care of the shrub that has a decisive influence on the quality of the crop.
Pruning raspberries involves a large range of different works:
- removal of dead, old, dry, damaged branches;
- cutting down excess trunks and root shoots;
- reduction in the length of shoots;
- binding bushes together, if necessary.
When is the best time to do it?
This procedure should be carried out three times a year in different seasons: spring, summer and autumn. During each season, pruning has certain features and nuances. Let's take a closer look at each case.
spring
It is extremely important to prune raspberries in the spring, because the amount of the crop will directly depend on how well the shrub is prepared for the season. This procedure will not complicate even beginner gardeners, since it does not require special skills to implement.
Rules and deadlines
In the period from the beginning of March and in April, it is necessary to carefully and carefully raise the shoots, then thin them out at the base, leaving only the strong ones. If the tops of the shrub are frozen in winter, then the branches must be shortened to the point where healthy buds begin. After that, you need to tie the raspberries to the trellis - a special lattice that will serve as a support for the shrub. In the same case, when there were no frozen shoots, you still need to cut the branches by about twenty centimeters. Thus, the growth and development of new inflorescences is stimulated.
The main thing is to get rid of old and damaged shoots. After that, you need to move on to pruning and shortening the young shoots. This procedure is carried out according to the usual scheme and involves pruning most of the raspberry bush.
As a result, the shoot should be located at a height of about 50 centimeters from the ground, and the number of healthy branches on it should not be more than six.
For convenience, you can remember a simple formula: on one square meter of land there should be from fifteen to thirty healthy shoots. This is the optimal amount at which the plant will receive full access to oxygen.
To make it even easier for you to deal with the raspberry trimming procedure, remember a simple reminder for such an event.
- Spend spring pruning as soon as it gets warmer, that is, in March or early April. At this time, the earth is already melting, saturated with moisture and warming up.
- Use only sharp tools for work. A good pruner will greatly facilitate and speed up the work. And if you treat it in potassium permanganate before pruning, it will also help not to introduce harmful bacteria into a fresh cut of the stems.
- Cut off shoots at the root. If the infected shoot is not completely removed, the disease can spread to healthy bushes.
These rules will help you get a healthy, well-groomed shrub that will delight you with a rich harvest all season.
Do not rush with spring pruning of raspberries.Before the procedure, be sure to check the air temperature at night - it should not be too low, and the soil should be completely thawed, without frozen areas.
Also note that the timing of this event in different regions, depending on climatic conditions, may be shifted.
For example, in the southern parts of the country, shoots can be pruned as early as March. While in Central Russia you should not start pruning before April or May. And in Siberia and the Urals, only June can sometimes be the best time.
Pros and cons
Proper pruning of a raspberry bush has a lot of advantages. Thanks to her, the plants develop fully, the berries are large, without pests. Even the appearance of your garden becomes much better and cleaner.
The disadvantages of such a procedure can only be attributed to the fact that such work needs to allocate time. In addition, you should be extremely careful not to prick yourself on the raspberry sprigs. Of course, if the variety of shrubs on your site has thorns.
Care
After completing the procedure, it is important to regularly monitor that the shrub does not form new damaged or infected branches. If you find them, then immediately remove them so as not to damage healthy shoots. Also, experts strongly recommend carefully disinfecting and fertilizing the soil. Both organic and mineral fertilizers are suitable for top dressing, they equally affect the yield of the shrub.
From organic fertilizers, peat, compost, chicken and cow droppings give an excellent effect. As well as wood ash, which must be added in the amount of 150 grams per 1 sq. m of land. Of the mineral dressings, phosphorus, potassium and nitrogen-containing substances are best suited.They help the shrub in a short time to increase the mass of greenery, rhizomes and fruits.
In order to prevent infection of the remaining stems after pruning, you can independently prepare for this an effective solution based on copper sulfate and slaked lime. Or use any other insecticide-fungicide.
Consider common mistakes when pruning raspberries in the spring.
- Dry and infected shoots are not completely cut out. As a result, the shrub becomes too dense. In the future, it will be quite difficult for the gardener to take care of the raspberry, loosen it and fertilize it. In addition, excess vegetation significantly affects the quality and quantity of the crop.
- Excessive or insufficient stem shortening. If you cut too much, then the plant will take a long time to recover, which means that the crop will have to be harvested later. In the opposite case, when the plant is not shortened enough, the shrub also becomes overloaded. And if this season does not give negative consequences, then next year the harvest will certainly decrease.
- Working with bad tools. The secateurs or pruning knife must certainly be sharp, only then it will be possible to make an even cut and avoid damage to the main part of the trunk and branches. Otherwise, plants are at risk of infection with harmful microorganisms.
Summer: features
Processing of bushes in the summer is carried out immediately after you have collected the last berries, most often in August. It is important to remove all those shoots that will no longer bear fruit. This is necessary so that the shrub has more strength and nutrients for the development and growth of young raspberries with fruit buds.At the same time, even the smallest stumps and stumps should not remain after trimming. Otherwise, pests and pathogenic bacteria may then appear in them.
You should also regularly, about two to three times a month, carefully inspect the shoots for the presence of dry branches and yellowed leaves. The sooner you rid the shrub of them, the better it will grow.
By the way, if you find an extra shoot that has not yet had time to take root, then you can get rid of it by simply sticking a shovel next to it. Soon the leaves will dry up on their own.
The more often you carry out such simple preventive procedures, the easier and more effective it will be to grow raspberries. And the harvest will increase rapidly.
autumn
Regardless of what kind of raspberry you have (standard, remontant, ordinary), it must be prepared for the winter period. It is important to carry out this procedure before the onset of the first cold weather. Pruning in autumn occurs according to exactly the same rules as in summer and winter. However, there is one caveat: since the plant already needs to be prepared for winter, its branches must be grouped immediately after pruning.
Some gardeners additionally bend branches and trunks to the ground so that they do not break or deteriorate under the influence of strong winds and other adverse weather conditions. And also without fail, it is necessary to carefully protect the plant from frost: close it with any material suitable for these purposes (spunbond, agril, lutrasil).
According to the Sobolev method
There is not only the classic method of pruning raspberries. Even in the Soviet Union, the Sobolev technique was invented, which is performed according to the double pruning scheme. Despite the fact that the technique is no longer new, it does not lose its relevance today. Pruning according to Sobolev takes this procedure to a new level, allowing you to control the density of shoots.
- First cut. It must be carried out as soon as the height of the bush reaches a height of 75-100 cm, that is, approximately in May-early June (the exact time depends on the specific region). This will contribute to the awakening and intensive development of "sleeping" lateral buds - just on them the fruits appear at the beginning of the season. And the seedling will grow not in height, but in width.
- Second cut. It is decisive and is performed at the beginning of the second season, when leaves are already appearing on the seedlings. It is necessary to shorten the tops of the lateral inflorescences by about 10 centimeters. And by the beginning of fruiting, new branches will appear on them, strewn with a large number of juicy raspberries.
Using the Sobolev method, you can significantly increase the yield of a shrub. Strictly follow this scheme, regularly feed the bush with organic and mineral fertilizers, and your harvest will be simply huge!
Refurbishment: how and when?
Pruning remontant and standard raspberries deserves special attention. Remontant varieties are able to bear fruit almost continuously throughout the season. That is, bloom and fade several times during the summer. At the same time, remontant raspberries can bear fruit not only on two-year-old shoots, but also on annual ones. This means that you will be able to harvest a fresh crop right up to the first snow.
Choosing a specific time for pruning such a shrub should only be based on the climatic features of your region. So, in the southern regions, this procedure is usually carried out in the fall, immediately after the end of the fruiting period. While for the northern regions it is better to choose early spring.If you prune a perennial shrub in the fall, then you need to remove all the branches that have already borne fruit under the root. If the shrub was planted only this year, then it is enough to simply shorten the shoots to a height of no more than twenty centimeters. This way you will get strong and healthy shoots next season, because pests will simply have nowhere to settle. Such pruning of remontant raspberries allows you to save as many nutrients as possible in the root system of the seedling and allow the plant to overwinter without problems.
In the spring, the bushes should be pruned before the buds open, around March-April. At the same time, if the buds are already swollen, it will be much easier for you to recognize the dead branches, which must be cut to the first live bud.
gardening tips
Experienced gardeners know everything about pruning raspberries and carry out this procedure regularly. However, even if you have never encountered such a job, you can easily cope with it. Let's look at a few more tips to remember when trimming bushes.
- Immediately remove cut and dry branches from the site, but rather burn them, observing all safety measures. This measure is necessary in order to prevent the spread of harmful and dangerous microorganisms that could remain on infected twigs and stems.
- In order for the shrub on your site to always be in excellent condition, it is important to simply strike a balance. Remember the rule: how many old inflorescences you removed, the same number of new branches you saved. So you prevent unwanted thickening of the raspberry and significantly reduce the time to care for the plant.
- If you want your harvest to be rich, and your berries sweet and juicy, make sure that the shrub has enough fresh air and sunlight. The greater the distance between the individual bushes, the better the lighting and ventilation, and hence the crop.
Water the shrub with enough water in time, protect the branches from pests, regularly weed and loosen the soil, and trim the bushes. Here are all the necessary steps to help you always enjoy a rich harvest of ripe and delicious raspberries!
