All about growing raspberries: a lot does not mean difficult
Both adults and children love to eat raspberries - they are juicy, sweet and healthy. If you are the owner of a summer cottage or a small garden, then it will not be difficult for you to grow several fruit-bearing shrubs. It is enough to know the basic rules of care, cut off the damaged parts in time, fertilize, water the raspberries regularly, and prepare the crop for winter in the fall. We will tell about all this, based on the advice of experienced gardeners.
plant description
The common raspberry belongs to the rose family. It grows in nature both in the wild along the banks of rivers and in forests, and is planted by summer residents as a garden crop. In total, there are several hundred varieties of raspberries in the world, many of which were known several millennia ago. As a horticultural crop, raspberries began to be systematically planted in Europe in the 16th century.
It is not only a tasty berry, but also a source of vitamins, minerals and other nutrients. This plant is very unpretentious and can grow on its own, but it is the right care that will help increase the yield of the berry.
Best planting time
Raspberries can be planted in both autumn and spring. To decide when it is better to plant, you need to know that for different climatic zones, the time for planting raspberries will be different. Since autumn is long in the southern regions, autumn planting in late September - early October is preferable. Raspberry seedlings will have time to give roots before frost, and in the spring they will begin to grow and develop faster.
In the southern regions, the spring is dry, planted bushes may enter the bud break phase without having time to take root. As a result, raspberries may simply die. As a rule, weakly winter-hardy varieties are planted in spring. There are also remontant varieties that bear fruit twice a year.
The spring planting method is suitable for the northern regions. Spring there is wet and protracted, which favorably affects the survival rate of seedlings. But in the fall, it is not recommended to plant raspberries, so that frosts do not suddenly strike and crops are not damaged.
As for central Russia, raspberries can be planted both in autumn and in spring. Although, if you listen to the opinion of experienced gardeners, autumn planting will give the best result. The main thing is to choose frost-resistant raspberry varieties.
Planting in the spring in the open field
Pros and cons
When planting raspberries in the spring in the country in the open field, there are pros and cons. The main disadvantage is that in the spring it is difficult to guess the exact time of planting, because there is no year for a year, spring can be early or late, and in different climatic zones agronomists plant raspberries at different times. Planting agrotechnics in autumn and spring is almost the same, but the degree of plant survival is different.
In the spring, the plant literally "pulls" nutrients from the ground, and if you miss the right period and the roots do not have time to take root, the seedling will simply die.In addition, in spring the weather is very changeable and can bring surprises both in the form of frosts and in the form of heat. And in the fall, as a rule, the root system has time to take root before the onset of cold weather.
Selection of seedlings
Preparation for planting in spring and autumn is different. For spring planting, you can use both just purchased material and dug up in the fall, which has lain in the refrigerator all winter. When planting seedlings, keep in mind that in the same area, raspberries will grow up to 10 years, and after that, the yield will decrease significantly, as the soil is depleted. The next time it will be possible to plant raspberries here only after 5 years.
Site preparation
Spring planting of raspberries requires the implementation of preliminary steps, including choosing the right place for raspberries. Since the land for spring planting has been fertilized since autumn, there will be no particular hassle with preparing the place. The main thing to remember is that choosing a well-lit area is the key to a high yield. Therefore, cut the bushes in time so that the stems and leaves do not obscure each other.
Since raspberries thrive in light, fertile soils, don't make the mistake of choosing soil that used to grow potatoes, tomatoes, or peppers. But legumes or cereals will be the most optimal predecessors.
Distance and depth
In early spring, pits 50x40x40 cm are dug, while the fertile layer is thrown to the side. Leave a distance between the pits of at least 50 cm, and between rows - 1.5 meters. For the top layer, you need to ensure the timely application of fertilizers, then place a raspberry seedling in the pit, straighten the roots and fill the pit with the remains of a mixture of fertile soil with fertilizers.
Compact the top layer, make a hole around the seedling and fill it with water.At the end, fill the hole with humus and sawdust, and cut the seedling so that a “stump” 30 cm high remains. If there is no rain, water the seedlings again the next day.
Fertilization
You will have to prepare the soil for spring planting in the fall (just dig up the ground and add 2 buckets of humus per 1 sq. M of land, a glass of superphosphate and potassium sulfide each).
The introduction of artificial fertilizers in the spring is not recommended so as not to burn the young raspberry roots.
Ways
If you want to double the number of raspberries harvested on your site, pay attention to the innovative method of growing this crop according to the method of the Kurgan gardener Alexander Grigoryevich Sobolev. He advises planting raspberries in a nested or ribbon way. When nesting seedlings, a distance of 70-90 cm is maintained. A row is separated from a row by 1-1.5 meters from each other.
With the tape method, plants are planted to a width of 40-45 cm, and the row spacing is 1 meter. Thus, a tape of shoots is formed on the site. It will be necessary to thin out the raspberries from time to time and replace the old trunks with new ones. The main thing when growing raspberries is to avoid dense plantings.
The main feature of the Sobolev method is the use of two-time pruning of raspberries, which is necessary to renew the bush and, accordingly, increase the yield. In addition, pruning helps to get rid of old and diseased branches, instead of which new strong shoots will grow. We'll cover this method in more detail in the How and When to Crop section.
If the majority of summer residents use the standard bush planting method, then the trench method is used for industrial production or when breeding raspberries for sale.First, the site is prepared, that is, it is cleared of stones, weeds and other waste. A trench 50x60 cm is dug, and the row spacing is 1-1.5 meters.
If groundwater is present on the site, drainage is laid out at the bottom of the trench, then a nutrient layer of earth and a mixture of mineral and organic fertilizers are placed. Seedlings in the trench are located about 40 cm apart. Further steps repeat the landing method in the classic bush method.
Repair view: nuances
When planting remontant raspberries in the spring, it is necessary to prepare the soil since autumn, dig up the ground and fertilize it. A seedling for spring planting should have a developed root system, and the height of the shoot should be no more than 20-25 cm. The depth of the planting pits should be about 40-50 cm, and the distance between them should be 70 cm. Before planting, the roots are dipped in a solution of clay, black soil and cow.
Straighten the roots of the seedling and fill the hole with earth so that the root neck is at the level of the site. After compacting the earth, watering is carried out (for each seedling, about 5 liters of water will be needed). After it has been absorbed, the soil is mulched with sawdust, bark, straw, or other plant debris.
During the autumn planting, the algorithm of actions is exactly the same, only the soil will have to be prepared in the spring.
In the Volga region, Moscow region, Siberia: features
The option of spring planting raspberries is suitable for the Moscow region and Siberia, since the spring is long here, and gardeners have time to root the seedlings before their vegetation begins. And in autumn, on the contrary, frosts can come suddenly and destroy crops. For the southern regions of the Volga region and the Kuban, it is better to choose an autumn planting, since autumn is long and warm there.You will not only have time to slowly complete all the work, but also give time to the raspberry root system to grow and get stronger.
For the central regions, planting dates for raspberries are the end of March or the beginning of April. For the northern regions, this is the end of April - the first decade of May. The first sign that it is time to prepare seedlings is the beginning of snow melting.
If the night temperature does not drop below 5 degrees Celsius for several days, then raspberries can be planted in open ground.
Common Mistakes
A common mistake of inexperienced gardeners is planting seedlings deep, in fact, the roots should not be deepened more than 8 cm. If you purchased seedlings from a nursery, pay attention to the old soil level visible on the stems and focus on it.
Some summer residents, in an effort to save space on the site, make narrow aisles. In fact, it is better to leave them 1.5-2 meters so that the raspberry plantings do not close. As a result, the bushes will not receive the sun, and you will lose part of the crop.
Spring and summer care
Provided that the correct treatment of raspberries was carried out in the spring, in the summer it will be enough for you to remove weeds on time and, in case of plant disease, treat them with special solutions. In the usual climate of central Russia, natural precipitation will be quite enough for raspberries. But if the time is especially dry, the bushes will have to be watered every day. At the same time, biosolutions can be added to the water to feed and accelerate the growth of plants.
In addition, you will have to regularly and very carefully loosen the soil so as not to damage the roots of the plant. For this purpose, you can also plant green manure between raspberry bushes, which will not only improve the composition of the soil, but also prevent the growth of weeds.
How, when and what varieties to plant in a greenhouse?
Raspberries are a rather unpretentious plant, therefore, when it comes to growing this crop in a greenhouse, many people wonder about the need for this. In fact, this is a great opportunity to significantly increase the yield of berries, as well as protect the culture from all sorts of vagaries of nature.
Mostly in the greenhouse, gardeners grow remontant varieties of raspberries, which bear fruit twice a season. And some even manage to grow berries all year round.
This is possible if there is a well-equipped greenhouse with heating and a separate place for the mother liquor.
Here are just a few reasons to try planting raspberries in a greenhouse:
- fruit ripening occurs faster and continues until late autumn;
- the harvest will increase significantly, and the berries will be large and sweet;
- in closed ground, the cultivation of any variety of raspberries is available;
- in the greenhouse, the plants will be under reliable protection from natural disasters such as hail, frost and strong winds;
- the risk of infection of bushes with diseases and pests is significantly reduced;
- you will be able to treat the berry with chemical fertilizers to a minimum, and, possibly, do without them at all, respectively, the harvest will be environmentally friendly.
The optimal species for growing in a greenhouse, according to experts, are:
- "Hercules" (high-yielding variety with large berries);
- "Ruby Necklace" (excellent variety with fragrant deep red raspberries);
- "Apricot" (an unusual variety with yellow-orange berries);
- "Morning dew" (small yellowish raspberries);
- "Bryansk Divo" (high-yielding variety with large fruits);
- "Orange Miracle" (has a large orange raspberry).
Technology
The technology for planting raspberries in closed ground is as follows:
- we prepare the soil: we introduce peat and humus into it;
- on the seedling we leave 1 shoot 20 cm long, and cut off the rest;
- the root system is soaked in water for several hours or dipped in a clay solution immediately before planting;
- in the greenhouse we dig a trench 50 cm wide and 40 cm deep with a distance between rows of 2 meters and between seedlings - 60 cm;
- during planting, pay attention to ensure that the neck of the root is flush with the ground;
- after planting, compact the soil and water it;
- if you are using seedlings in pots, be sure to provide drainage holes.
Growing methods
To grow raspberries throughout the year, summer residents use the conveyor method. It lies in the fact that seedlings are planted in January, then in March, and so on every second month. At the same time, the raspberry crop can be harvested within 2 months after planting.
The bushes from which the crop was harvested are cut and left at rest. When growing raspberries in this way, you will need bait and frequent replacement of bushes, and heating of the greenhouse begins in September-October.
Caring for greenhouse raspberries includes some nuances.
- Since raspberries need a constant supply of fresh air, you need to ventilate the greenhouse as often as possible, of course, subject to warm weather. The normal temperature for the growth of this crop is about 20 degrees Celsius during the day and about 13 degrees Celsius at night. Humidity should be maintained within 65-75%. Raspberries will have to be watered 2 times a week, and once a week loosen the ground around the roots to ensure the flow of oxygen to them.
- Soil mulching is not required, but recommended. Sawdust, walnut shells are used as mulch, you can cover the soil with agrofiber. Raspberries will have to be fed 2 times a month, introducing nitrogen mineral fertilizers, manure and ammonium nitrate with water. In order for raspberry flowers to be pollinated, it is recommended to open the greenhouse so that bees and bumblebees enter there.
Harvesting
In order for the raspberries to be sweet and fragrant, the bushes stop watering the day before they are harvested. Harvest raspberries in the morning every day until they bear fruit. Since raspberries are tender berries, they cannot be transferred from one container to another, so the fruits are placed in portioned packages (small cardboard or plastic boxes) and placed in the refrigerator.
Greenhouse cultivation of remontant raspberries can become a serious business for a small farmer. With the right approach to organizing a greenhouse and caring for raspberries, planting them indoors can bring excellent profits throughout the year.
How to plant and care for in the fall?
In autumn, it is worth starting to prepare a plot for raspberries a month before planting, which usually occurs at the end of September - beginning of October. The earth is dug up, freed from weeds and fertilized with manure (3 buckets per sq. M), superphosphate (400 g per sq. M) and potassium sulfate (200 g per sq. M). And if the soil of the site is peat, add 4 buckets of sand per square meter to it. m. Many summer residents prefer autumn planting, as the seedlings take root better, and you can slowly prepare the site.
Raspberry farming includes garter plants. Moreover, you can tie up raspberries according to different schemes. Temporary supports will help you move between rows more easily, support the shoots with berries and greatly simplify the harvesting process.As a support for tying the berries, a T-shaped trellis made of wood or metal is suitable. Holes are made at the ends of the crossbars and twine, wire or agroshpaler are attached. The T-pillars are removed in the fall and re-mounted the following spring.
Transfer
Over time (after 4-6 years), the yield of raspberries decreases, so caring summer residents try to plant them. Also, this measure is necessary if the raspberry grows in the shade or has ceased to bear fruit. Most amateur gardeners replant shoots in the spring, hoping that they will be able to get a crop in the summer or early autumn. Raspberries are transplanted into holes 20-35 cm deep, sprinkled with compost and covered with soil, which is compacted.
Bushes are watered at the rate of 6-8 liters per seedling. Moreover, if the terrain and soil are dry, the furrows and holes are not completely sprinkled, leaving room for water collection. And in waterlogged soil, raspberries are planted in raised beds, water is diverted using inter-row furrows. After transplanting, the soil is mulched with sawdust, straw, peat or dry bark.
reproduction
Raspberries are propagated by ready-made seedlings, layering or seeds. If you have time and enough patience, you can easily prepare seedlings from seeds at home. If there is a backlight, the seeds are sown by the end of February, so that in the spring you already have tall and strong seedlings. If the seeds grow in natural light, sowing can be done in mid-March.
Seedling boxes are filled with a universal soil mixture. Seeds are scattered over the surface; it is not necessary to sprinkle them with another layer of soil. The soil is poured through a sieve (for uniform distribution of moisture), covered with a film and transferred to a warm, lit place.
As a rule, the first sprouts appear after 3 weeks, but to shorten this period, you can water or treat the seeds with growth stimulants.
Also popular among summer residents are methods of propagating raspberries with seedlings by dividing by bushes or layering (offspring) and cuttings. The easiest shrub to propagate is lignified offspring. To do this, one-year-old offspring are dug up in the fall, which grew up next to the mother bush. Do this carefully, trying to save the maximum number of roots.
Reproduction by green offspring can be carried out in the spring, when they reach a height of 10-20 cm. To do this, we retreat 40 cm from the main bush so as not to damage the roots and dig up the offspring with a clod of earth.
If the raspberry stems are affected by the disease, then the method of propagation by root cuttings, which is carried out in spring or autumn, is suitable. We dig out the earth at a distance of about 40 cm from the bush. We carefully dig out the adventitious root, cut healthy roots into pieces with at least 1 kidney. At the same time, the overgrown roots must be preserved. The cuttings are planted in grooves 5-10 cm deep one after the other, covered with earth and watered.
For propagation by green cuttings, root offspring are taken, which were cut off during thinning of raspberries. In May-June, shoots 8-15 cm high are selected. They are cut to ground level and tied in 10-15 pieces are placed in a 0.1% solution of "Heteroauxin" for 16 hours. After this procedure, the cuttings are planted in a greenhouse. After 4 weeks, the cuttings are placed for growing in open ground.
Propagation of raspberries by dividing the bush is used for valuable varieties that give a small number of root offspring. When the bush is divided, roots and 2-3 healthy shoots are left in the seedling.
How and when to cut?
Preparing plants for winter is, first of all, proper pruning. Pruning raspberries is necessary in order to increase its yield. It is better to do pruning at the end of summer or autumn, when fruiting is completed, and the shoots gradually die off.
They should be removed at the very root, as close to the ground as possible. When pruning, all diseased shoots are also removed. In general, after trimming by 1 sq. m. there should be no more than 10-12 shoots so that the plants receive enough lighting. After pruning, the cut shoots are burned.
According to the Sobolev method, a double pruning of raspberries is carried out in spring and autumn. This is necessary so that the harvest is several times larger than usual. Primary pruning is done before the start of the growing season. Leave the bush about a meter high from the ground, and cut the tops by 10-15 cm. If earlier the plants had fruiting only at the tips, then after such pruning, all the shoots and the top of the bush will bear fruit.
In fact, on each shoot you will get 2-4 additional stems. When pruning in spring, it is important not to miss the moment: if spring comes early, prune in May, if late - in early June. By August, new shoots will reach a height of 30-80 cm and form a very lush bush.
The second pruning according to Sobolev is no less important and is done in the fall in the second year of the plant's life. 10-15 cm is cut not only from the top, but also from additional shoots. And by the summer, the shape of the raspberry bushes after such pruning will become like triangle-trimmed trees. Large fruits will soon appear on each pruned branch.
Using the Sobolev agricultural method, every week you will observe the appearance of new ovaries, flowers and berries.
What is sick and how to treat?
Raspberries can be disturbed by various diseases, and every summer resident should know how to carry out the treatment so as not to lose the crop.
- With fungal anthracnose, gray spots with a purple rim appear on the leaves and stems. Gradually, ulcers appear on the leaves, and the greens die off.
- To combat raspberry curl, when the leaves become small, stiff and wrinkled, the only way out is to burn the infected shrubs.
- Purple spot affects raspberries often, causing the bushes to dry out. Purple spots appear on the stems, which darken at the edges. It is necessary to destroy the infected shrubs, and treat the rest of the raspberries with a Bordeaux solution.
- Powdery mildew appears, as a rule, in wet weather in early summer. The shrub is covered with white bloom, the leaves dry, and the berries are deformed. In this case, raspberries are treated with Bordeaux liquid three times.
Pest control
The raspberry beetle from the soil falls into raspberry flowers in May. By eating them, he thereby damages the future fetus. You can get rid of this pest by shaking the bush. After that, you will have to dig the soil under the bush and in the aisle to destroy the larvae. You will also have to additionally spray the raspberries with Decis, Confidor or a 10% solution of Karbofos.
Stem flies, or rather, larvae, gnaw passages to the roots inside the stems, so the shoots gradually wither and rot. To destroy insects, you will have to cut out old shoots that do not bear fruit at the root.
The shoot aphid slows down the development of the shrub, and the leaf aphid carries viral diseases. You need to fight this pest by spraying the shrubs with "Aktellik" or "Karbofos" as soon as the buds open.
The spider mite is located on the underside of the leaves and braids them with cobwebs. Over time, such leaves dry and fall off, as the tick sucks the juice out of them. To destroy the pest, you can spray raspberries with acaricides. And with a large number of pests, plants need to be treated up to 4 times a season with a break of 10 days.
Variety overview
Raspberries are common, large-fruited, standard and remontant. Ordinary varieties are unpretentious in care and perfectly adapt to various climatic and weather conditions. The disadvantage is not very large fruits and not such a plentiful harvest as every summer resident would like.
Large-fruited raspberries have sweet and juicy berries and increased yields. The standard raspberry resembles a tree in appearance and reaches 1.5 meters in height. The advantage of this variety is that you do not need special supports.
Remontant raspberries are chosen by those who want to enjoy juicy berries as early as possible, because this variety produces a crop in the first year of planting, and then bears fruit twice a year - in summer and late autumn.
Versatile varieties of raspberries optimally meet the requirements of gardeners and are suitable for various types of climate. Consider the most popular types.
- "Aboriginal" with a tall bush up to 2 meters high without thorns. Harvest from one bush - 5-7 kg. The fruits are large, with fragrant pulp and a sour taste. The variety is resistant to diseases and almost not susceptible to pest attacks. Winter hardiness is average, so it is suitable for growing in the south or in central Russia.
- "Alyonushka" has more acidic berries, so not everyone likes to use them raw, but for making jam, such raspberries will be just right.The bush grows up to 2.2 meters in height, so the yield of this variety is quite high - up to 13 kg per bush.
The variety is resistant to pests and high temperatures. Therefore, this type is suitable for the southern regions of the country.
- Variety "Vera" will give gardeners medium-sized, but the sweetest fruits. The yield reaches 5 kg per bush, the variety is resistant to pests and drought, although frequent watering will only improve the taste and fruitfulness of raspberries.
- Raspberry "Canadian" has sweet berries and high productivity (up to 12 kg). Its advantage is that berries can be stored for a long time. The plant withstands summer heat and drought well.
- "Marlboro" will bring up to 13 kg of raspberries from a bush of sweet and large fruits. The height of the erect bush reaches 2.5 meters, so it is recommended to trim it from time to time to increase the yield.
- "Meteor" does not have a high yield (up to 2 kg per bush), but it is one of the first to ripen - already in June you will be able to feast on juicy berries. The advantage of this variety is resistance to fungal diseases and good frost resistance, so it can be grown in the north, the Urals and Siberia.
- "Taganka" late ripening is also suitable for the northern regions, as the variety is able to withstand temperatures down to -20 degrees Celsius without shelter. The yield is 4-5 kg per bush. The variety is resistant to diseases and extreme weather conditions.
Early
Early ripe raspberries cannot boast of high yields, but already in late May - early June, they will delight summer residents with the first juicy berries. Of the varieties popular according to reviews of gardeners, we note a few.
- "Scarlet Sails" has a yield of up to 1.7 kg.This is a winter-hardy variety - if the main buds freeze, the plant will still produce a crop using axillary buds.
- "Runaway" gives up to 2 kg of fruits from a bush, and raspberries have an unusual apricot hue and a delicate aroma. The variety has a high frost resistance.
- "Patricia" - large-fruited variety with good yield (up to 5 kg). The berries do not fall apart and do not crumble, while juicy, ripe and sweet.
The winter hardiness of the variety is average, so use it in more southern regions or bend down and hide the shoots under the snow for the winter. The variety is disease resistant.
Mid-season
Most summer residents choose mid-season varieties, as they bear fruit relatively early, while not losing in yield, like early varieties. This group does not require such care as early raspberries and is more resistant to diseases. Consider the most productive and popular varieties.
- "Tarusa" or in the people "raspberry tree". Its height reaches 1.8 m, and the yield is 6 kg. What distinguishes the variety from others is that there are no thorns on the branches, which means that the harvesting process is simplified as much as possible. This variety ripens in the second decade of July.
- "Hussar" has a yield of up to 3 kg per bush. Ruby berries have a pleasant sweet and sour taste. The winter hardiness of the variety is average, but it is not afraid of droughts and is resistant to diseases.
- "Zeus" valued by summer residents for its special shape and appearance. Its oblong berries are located on the side branches in groups of 12-14 pieces. With abundant watering and proper care from such a bush, you can harvest up to 12 kg.
- "Glen Ample" was bred in England, and the fruits can grow on the shoots of the previous year. The berries are medium in size and pleasant in taste. The advantages of the variety are winter hardiness, drought resistance and resistance to diseases and pests.
Late
Late-ripening varieties have one drawback - you have to wait for berries until the end of summer or early autumn. But there are more than enough advantages: they are not afraid of frost, they give a high yield, they are distinguished by high winter hardiness.
- "Kirzhach" yields up to 6 kg per bush. The variety is resistant to low temperatures, dry weather and undemanding to soil fertility.
- "Patricia late". The variety is similar to "Kirzhach", but has a long ripening period.
- "Mirage" - high-yielding variety with large elongated berries. Even when fully ripe, the berries do not crumble. Winter-hardy and resistant to diseases and pests.
Remontantnaya
Remontant varieties will allow you to collect a very large amount of the crop.
- "Penguin" has a standard crown type and consists of a small number of shoots. Harvest arrives in early September. The berries are dark crimson in color, rounded, resistant to diseases and pests. The yield per bush is quite high - up to 15 kg.
- "Indian summer". Harvest ripens in the second half of August, and the collection continues until the frost itself. The berries are small, sweet and sour in taste and fragrant. The variety is popular because of the abundant fruiting and excellent quality of the berries.
- "Hercules" has large fruits and upright shoots that do not require support. Harvest ripens in early August, and fruiting lasts until the first frost. The popularity of this variety is due to stable yields, resistance to fungal diseases and raspberry mites.
gardening tips
Here's what you need to know:
- Raspberries grow best in full sun, but if there is not enough space on the site, they can withstand some shade. She likes more acidic soil (pH 6.0-6.5). But in alkaline soil it will suffer from an excess of iron and a deficiency of manganese.
- If you grow raspberries in a greenhouse, experienced gardeners advise removing end frames from the frame in warm weather (at least 20 degrees Celsius) to provide raspberries with access not only to fresh air, but also to beneficial insects.
- To make raspberries large, learn how to properly water the plant. Irrigate not the aerial part, but the basal one, so that moisture does not evaporate from the leaves. If you notice that the greens are starting to fade, this is a sign that watering needs to be increased. In addition, during drought, loosening the soil under the bush will help the plant so that oxygen enters the roots.
- If you have planted a lot of raspberry bushes, then there is a little trick that will help you harvest from different bushes at short time intervals and, accordingly, be in time so that ripe berries do not crumble. When pruning in the spring, make it at different heights.
To do this, conditionally divide the bushes into 3 groups. The first is cut to 10-15 cm, the second to half the height, and in the third, leave only 15-20 cm. In this case, the fruit will ripen sequentially, and not simultaneously. And you will have time to remove all the berries, even from a large raspberry.
And in order not to be upset because of the lack of a rich harvest, do not grow raspberries in one place for more than four years, but transplant them to a new place.
