A psychologist from Japan created an image of strawberries without the color red to show that color perception tricks the brain - despite the fact that there are no red pixels in the picture, people still see red in it.
Psychology professor Akiyoshi Kitaoka posted on his Twitter a picture in which there is no red color, writes Motherboard. However, people still think they see red because there are strawberries in Kitaoka's photo:

“The strawberries appear red, even though there are no red pixels.”
US neuroscientist Matt Lieberman confirmed that there is no red in the photo:

“There are NO red pixels in this image. Excellent demonstration of color constancy."
Color constancy - feature color perception a person, allowing him to “recreate” missing or altered colors in the brain, if he knows what they should be (or is sure that he knows this).
The claim that a person is "making up" the color red by looking at an image has sparked controversy in the comments. The community did not believe the scientists and tried to prove that they wanted to pull off some kind of trick:
“I think I found some red pixels..?”

“Akiyoshi Kitaoka, you just don’t understand what Jpeg is, there’s a red one here. Jpeg has three channels - red, green, blue. This is where I removed the red channel.”
Other commentators examined the image and still found no red in it:

“I took out some of the reddest colors from the image and placed them on the right.”
“I drew three rectangles (using color swatches) to show the effect.”
But one user provided seemingly indisputable evidence:
https://twitter.com/EdwinNikkels/status/836922568279982080
“No red in the image? Look what I did to the “autotone” image in Photoshop. Photoshop instantly detects the red color of the original.”
In fact, the human brain colors images from memory, which is why we find red in the strawberries in the photo, Motherboard writes. Due to evolution, we have learned to understand that lighting can change, but the color of the object we are looking at remains unchanged. So, for example, a ripe banana will always seem yellow to us, even if we walk with it in rooms with different lighting from blue to red - we just see yellow banana under normal lighting and take it for granted that it will not change if we change the lighting. The same with strawberries in the photo: the brain sees the saturation of blue in the image and therefore automatically removes its excess, deciding that the strawberry is red.
To prove that people themselves come up with colors in images, Kitaoka showed another photo:
Do you think there's red here? And in the photo with strawberries?
Black Prince - excellent variety Italian selection. Ten years of hard work by the breeders of the New fruitis company made it possible to develop new variety with increased frost resistance, designed for cultivation in areas with moderately cold winters and rainy summers.
In the article:
Description of the variety with photo
The variety belongs to the group of medium-early ripening. The first fruits ripen on the 20th of June, fruiting continues until the beginning of autumn. The fruits retain their size throughout the season; in early varieties, the size of the berries noticeably decreases by the end of summer.
The Black Prince's bushes have original look, from a distance they can be mistaken for a potato bush, they are so big.
Advantage of the pulp variety high density, this quality ensures the possibility of long-term storage of berries. The period is impressive - two weeks. The black prince's harvest does not deteriorate when transported over long distances.
The variety is high-yielding. From one powerful tall bush You can get up to a kilogram of berries per season. When grown on a farm on an industrial scale, the average yield will be 20 tons. summer cottage One hundred square meters of land planted with black prince strawberries will yield about 200 kg.
The good thing about this variety is that it can bear fruit in one place for up to seven years. Productivity usually increases from year to year, this is especially noticeable when proper care.
The name of the variety Black Prince is due to the fact that when the berries ripen they acquire a very dark red color, appearing almost black at dusk. The color of the seeds is also black. The fruits are rather large and can weigh up to 50 g. The shape resembles a truncated cone.
The variety claims to tolerate well low temperatures in winter, the lower threshold is -20 C. In spring, plantings are not afraid of nighttime drops in temperature. In summer it does not tolerate drought well. The main focus is summer care- timely watering.
Features of cultivation and care
Best soil options:
- The soil is sandy loam.
- Forest gray soil;
- Loam is light;
Strawberry Black Prince prefers to grow on loose, breathable soils. Clayey, peat soils are not suitable, the plants begin to rot on them root system, the plant dies.
There should be enough sun on the site. Constant north and northwest winds are contraindicated. In winter, snow cover on the ridges is necessary, only in this case it will survive the winter with twenty-degree frosts well.
If the groundwater level is closer than 0.6 m, the site is not suitable; strawberries should not be planted in lowlands, where soil moisture is always high; mountain slopes are also not suitable.
To improve the structure of the soil and disinfect it, green manure is used. Sow the area a year before planting; mature plants are not removed; they are embedded in the soil when digging.
The bushes are large, so plants should be planted at a distance of 0.4 m in a row. Make row spacing 0.6 m wider, ventilation improves, it is more convenient to process bushes,
Variety value
- Nousually delicious berries, beautiful color.
- Maintaining large fruit size throughout the season.
- Increased pulp density, good keeping quality, transportability.
- Large harvest from one bush.
- Possibility of growing in one place for many years.
- Tolerates frosts well down to - 20 C
- Good resistance to pathogens.
Reviews from gardeners
Good feedback. The harvest is praised when planted with wide row spacing. Thickening of plantings leads to a decrease in yield, since the berries are smaller in size.
Greater productivity of the variety is noted in the second year of fruiting. Resistance to tick damage. Possibility of propagation by mustache, dividing the bush.
Farmers praise the Black Prince variety; they are satisfied with the possibility of growing in one place long time, keeping quality, frost resistance, good taste. Buyers at the market love this berry.
Photos of berries of the variety
Strawberry black prince is still little known among domestic gardeners. But the varietal characteristics make it possible to put it on a par with promising species. Garden strawberries black prince are great for growing in different regions our country, including the northern ones.
The Black Prince is the product of ten years of work by Italian breeders. Thanks to persistence researchers The New Fruitis company managed to obtain a variety that differs increased frost resistance.
Strawberries are great for growing in regions with short, rainy summers and moderately cold winters.
In terms of ripening time, the crop belongs to the medium early varieties. The first harvest of berries ripens on the 20th of June. The plant bears fruit before autumn time. Throughout the season, the berries maintain their size, while other early varieties become smaller by the end of summer.
The strawberry bush amazes with its unusual appearance. The plant is large and from a distance can be confused with potato tops.
The shape of the berries is cone-shaped with a slight truncation at the end. Their mass according to the description reaches 50 gr. Covered with black, strongly protruding grains, the dark red berries are slightly prickly. In the dark, their color appears black, hence the corresponding name.
Sweet fruits have juicy and dense pulp without voids. Due to their high degree of density, they can be stored for a long time - 2 weeks. Fruit do not deteriorate during transportation over long distances.
Black Prince is a high-yielding variety. One bush per season gives on average kilogram of strawberries. With one dacha hundred square meters you can get about 200 kg of berries. The variety is good for cultivation on an industrial scale.
This type garden strawberries It bears fruit in one place for 7 years, while the berries do not become smaller by the end of summer and the yield increases every year.
Planting strawberries
Strawberries should be planted at the very beginning of autumn so that they have time to take root before frost.
In addition, at this time of year there is a sufficient amount of micronutrients in the soil, which are so necessary for growth and development.
Selecting a location
Before you start planting, you must select right place, which must meet the following criteria:
- lots of sunshine;
- protected from the wind;
- deep groundwater.
Last point very important, otherwise the roots will begin to rot. For the same reason, you should not plant garden strawberries in lowlands, as well as on slopes, since water will flow down and the plant will not receive enough moisture.
You cannot plant black prince strawberries where potatoes, tomatoes or eggplants used to grow. Great option there will be a place where carrots, onions, legumes or grains previously grew.
The soil
Heavy clay soils where excess moisture predominates are not suitable for the variety. Strawberries prefer sandy loam, drained soil with excellent air circulation. This may be black soil or forest soil.
Having chosen a place, you need to prepare a bed. First of all, her dig up, removing all weeds. The soil needs to be well fertilized using organic matter.
Planting material
To avoid disappointments with planting material, you should purchase it from a specialized store or nursery. The distance between holes should be more than 40 cm, since the plant grows quite quickly.
The holes are watered abundantly and only then sockets are placed in them. Having straightened the roots, the seedling is buried in such a way that the growth bud (heart) remains on the surface of the earth. The soil around the plant is lightly compacted, irrigated and mulched.
Care
Every year it is necessary to remove the tendrils so that they do not take away the strength from the main bush.
Feeding is done twice a season. Once in the spring using nitrogen-containing fertilizers. The second time in the summer, when buds appear on the bushes, they are fed with fertilizer containing phosphorus. For the black prince Do not use preparations containing chlorine. This is detrimental to the plant.
After planting the bushes, it is important to maintain soil moisture, especially during the flowering period.
After the ovaries form, watering should be stopped, otherwise the berries will lose their taste. To prevent the bushes from suffering from drought, the soil needs to be mulched.
Strawberry propagation
When propagating black prince garden strawberries, the same methods are used as for other species:
- dividing the bush;
- seeds.
Mustache
The first method, invented by nature itself, is the simplest and least expensive. When choosing mustaches for propagation, take those that are located closer to the bush. The shoot should have 5–6 leaves.
In order for the plant to take root quickly and surely, experienced gardeners recommend not immediately separating the mustache. The socket must first be pressed to the ground and wait 36 – 40 days until it takes root and only then separate it from the parent bush.
An excellent time for planting is considered to be the end of August - beginning of September. Before the onset of frost, the seedling has time to get stronger and recharge with nutrients.
Strawberry black prince gives a mustache only the first three years.
Dividing the bush
When the plant stops producing tendrils, the second method of propagation becomes relevant - dividing the bush. Choose bushes that have most of all small shoots.
The crop is dug out of the ground and, using a knife treated with potassium permanganate, it is carefully divided into parts. The sections are processed with crushed activated carbon and planted in the ground.
Seeds
The most labor-intensive method is considered to be growing garden strawberries from seeds.
The result may be far from expected. Seedlings may not adopt varietal characteristics parent bush.
Seeds are obtained from the largest and ripe berries. Thin layer The pulp with seeds is cut from the fruit and dried. After drying, the seeds should be separated by rubbing the pulp between your fingers. They are stored in hermetically sealed containers no more than 3 – 4 years.
3 - 4 months before planting, the seeds are placed in water and kept at a temperature of 3 -5 degrees. Before planting, the seeds are thoroughly dried.
There is one more quick way seed preparation. Soak the bones for 15 minutes concentrated sulfuric acid solution, after which they are thoroughly washed for half an hour in running water and dried.
Planting seeds in February into small containers. Soil consisting of turf, dry peat and river sand(2:1:1) is irrigated and seeds are scattered on its surface. The containers are covered with polyethylene. The sprouts should appear in 10 - 14 days, and after 2 weeks the seedlings are plucked.
Autumn treatment of beds
In order for plants to survive winter well, they need to be prepared for it:
- remove mulch to avoid the development of fungal diseases;
- delete dry and yellowed leaves;
- clear the bed of weeds;
- loosen the soil so that the roots are not visible;
- fertilize the soil (manure, humus or vermicompost);
- a couple of times until frost is good saturate the ground with water;
- trim your mustache;
- Before the onset of cold weather, cover the crop with covering material.
Diseases and pests of crops
When growing black prince strawberries you need watch the leaves carefully. Sometimes they can tell about the presence of a disease, timely treatment which will help save the plant and preserve the harvest.
If there is a formation on the foliage yellowness, then the reasons may be the following:
- non-infectious chlorosis;
- mosaic;
- deficiency of magnesium or nitrogen.
If the foliage on the bush has begun dry out early, then this could mean:
- infection with root rot or fungal disease;
- damage to the root system by mole crickets or moles.
Despite the variety’s resistance to various diseases, if not properly cared for, the plant can become infected with gray mold, spotting, late blight, powdery mildew and anthracnose.
Application
Like any other variety of strawberries, black prince can be consumed not only fresh, but also made into various preparations: preserves, marmalade, compote and even liqueur.
In addition, the berries have found application in cosmetology. Thanks to the large seeds, the fruit can be used to make not only nourishing masks, but also peelings.
The plants are beneficial not only berries, but also leaves. The decoction helps fight coughs and relieves sore throats during colds.
Strawberry black prince rightfully deserves the attention of gardeners. With proper care, the plant will show itself with the best side and will give you an excellent harvest of delicious berries.
The young and promising strawberry “Black Prince” is increasingly found on plots. Why it has become so popular, we learn from the description of the variety, which is presented in this article.
Characteristics of the variety
Among domestic summer residents, a variety of garden strawberries with beautiful name"Black Prince". Although in everyday life it is more often called strawberry, but, like the famous Victoria variety, it is a completely domestic variety of large-fruited garden strawberries. These are monoecious sun loving plants, pollination occurs within one bush. Strawberries, on the other hand, are a dioecious crop with poor yields, so they are rarely planted on plots. The presence of heterosexual bushes makes pollination difficult.
Unlike garden strawberries, it loves shade and bears small berries.
“Black Prince” was recently bred by Italian breeders in the city of Cesena. The berry received this name for its burgundy color. Their dark color is added by black seeds on the surface, so from a distance the berries look almost black.
The bushes of this variety are powerful, spreading, with a strong root system. The leaves are green, medium in size, slightly corrugated, with a glossy surface. On long stems bush is formed a large number of ovaries. During the ripening period, under the weight of the berries, they bend towards the ground. The fruits are cone-shaped, reach a weight of 50 grams and do not become smaller by the end of the season, so up to 1.5 kg can be collected from one bush per season.
There are several main advantages of “The Black Prince”:
- a plant of this variety can successfully bear fruit in one place for about seven years, and the yield only increases over time, but the fruits do not become smaller;
- With age, the bushes produce less and less tendrils, so the older the bed, the less care it requires;
- the variety is considered frost-resistant: it easily tolerates winter frosts up to – 25°C and spring frosts, therefore suitable for moderate continental climates.
"Black Prince" belongs to the early varieties. The flowering phase occurs in May, and the first fruits ripen in mid-June. The variety bears fruit until late autumn. This yield is associated with the ability to continuously form new ovaries.
In addition to its excellent taste, the berries of this variety are juicy and dense. They have no internal voids, so the crop tolerates transportation well.
The disadvantages of the variety include poor tolerance to drought. But when proper organization If watered, it will bear fruit well in arid climates. Due to the small number of mustaches, a deficiency may occur planting material. The variety is easily attacked by the strawberry mite and is not resistant to white spot disease.
Strawberries "Black Prince" have a sweet taste with a slight sourness. The berries can be eaten fresh: they contain a large amount of vitamins and beneficial microelements. Jams, jams, compotes and all kinds of desserts are fragrant and tasty.
How to choose a landing site?
In order for the “Black Prince” strawberry to grow well and bear fruit successfully, you need to choose suitable site. The place should be sunny and at the same time protected from strong winds. Without protection from the wind in winter, the snow cover will be blown away from the garden bed, and the plant will quickly freeze.
Suitable soil for strawberries would be light sandy loam soils or forest sierozem. “Black Prince” will not grow on heavy and acidic soils, because the root system will quickly rot, even with drainage.
The site should not be located in a lowland or on a slope. In the first case, excess water will accumulate in the garden bed. In the second case, the water will drain, wash out the upper layers, and will not have time to be absorbed. Groundwater must be located at a depth of at least 70 cm.
A suitable place for planting would be an area where cereals and legumes grew. It is also good to plant strawberries after onions, carrots, beets, radishes and herbs. But you shouldn’t plant strawberries in place of potatoes, eggplants, tomatoes or cabbage. It is also recommended to avoid close proximity to these crops. Good neighbors for “Prince” there will be cereals and legumes. The pungent smell of garlic, onions, marigolds and nasturtiums will also help repel pests.
How to plant?
Strawberries can be planted both in autumn and spring. Each summer resident chooses a time convenient for himself. At spring planting the air should already warm up to +15°C, usually this happens in May. Autumn planting It is recommended to do it from August to October, so that young bushes have at least a month to strengthen. Strawberry seedlings or seeds can be used as planting material. The necessary seedlings can be purchased at special stores for plant growing or at a fruit nursery. This method is simpler, faster and more suitable for beginners. After purchasing, the seedlings can be immediately planted in the prepared bed.
If there is already a “Black Prince” on the site, then this simplifies the task, because the plant can be propagated using the mustache. To do this, you need to select the strongest rosettes closest to the main bush.
Planting seeds is more labor-intensive and is suitable for experienced gardeners. The seeds must be pre-soaked. For their rapid germination, you can use Epin. After this, the seeds are placed in the prepared soil, 2-3 pieces in one hole. The container must be closed and placed in a warm place until shoots emerge. This process will take about 2 weeks, during which time the seeds only need watering and aeration. After the first leaves appear, the strawberry shoots are transplanted into separate cups and transferred to a sunny place.
Important! Before planting strawberries in open ground seedlings need to be hardened off. To begin with, they place it for a short time near open window under cool air, then taken out to the balcony.
The bed for strawberries must be prepared in advance. Two to three weeks before planting, the soil on the site must be dug up along with fertilizers to a depth of about 20 cm. In this case, all weeds must be removed. If the soil contains a lot of clay, then it is recommended to add river sand at the rate of 2 buckets per square meter. If the content of sand or peat is high, the soil must be dug up with sawdust and humus. Dolomite flour is added to reduce acidity.
A mixture of superphosphate and potassium sulfate is evenly distributed over the entire surface. The proportions must be strictly observed according to the instructions on the packaging. After this, the soil must be dug up again and left for complete dissolution of all fertilizers. If planting is done right away, the roots of the “Black Prince” may simply burn.
The optimal width for a bed is considered to be 80 cm. Since the “Black Prince” bushes grow greatly, they need a lot of space, so the distance between neighboring bushes should be at least 40 centimeters, and the distance between the beds should be 50 centimeters. This scheme will ensure ease of care for the plant and its comfortable existence. After the bed is ready, strawberries are planted. It is recommended to do this in the evening, when the sun is no longer so active.
According to the scheme, holes are formed 15 centimeters in depth and 20 centimeters in diameter. The holes need to be watered and the water allowed to absorb. Young bushes of the “Black Prince” need to be carefully placed in the holes, straightened out the roots and covered with soil. It is important that the “heart” (as the growth point is called) remains 1–2 centimeters above the ground. Next, the soil near the bushes must be carefully compacted and watered again.
Care
Like any plant on the site, “Black Prince” will grow and produce bountiful harvest only with proper care. To do this, the plant needs to be watered, fed, loosened the soil, and fought with weeds, diseases and pests.
Watering
Strawberries of this variety are moisture-loving and do not tolerate even short-term drought. Therefore, it needs regular watering, especially immediately after planting and during flowering. During this period, you need to water every day in the evening. At the same time, there is no need to “flood” the plant: excess moisture can provoke root rot and disease.
After the fruits form, watering must be reduced to once a week, otherwise the berries will be watery and quickly spoil.
The water for the “Prince” should be warm. Watering is done at the root or in the grooves between the rows.
Loosening
After watering, the soil around the bushes must be carefully loosened. This will prevent the formation of a crust on the surface of the soil, and the root system will not be left without air. During the loosening process, you can immediately get rid of weeds.
Mulching
This procedure is performed twice per season. Soon after planting, the soil around the young bushes should be sprinkled with sawdust, dry weeds and waste from grain crops. This layer of mulch retains moisture in the soil and at the same time prevents the accumulation of moisture on the surface. This is especially important during the fruiting period - the risk of rotting berries is reduced.
The second time mulch is applied after harvesting. This extra layer helps retain heat and protect the roots from frost.
Top dressing
Fertilizers are applied several times:
- in early spring, before the start of the growing season, strawberries need to be fed ammonium nitrate or urea at the rate of 20 grams per square meter;
- at the moment of bud formation, feeding is carried out with superphosphate (40 grams per square meter);
- When the fruits ripen, it is necessary to add complex mineral fertilizers(“Agricola”, “Berry”), the proportions must be followed strictly according to the instructions on the package.
Removing a mustache
So that everything vitality strawberries were spent on the formation and ripening of fruits, it is necessary to get rid of excess mustache in time. In addition, they quickly multiply throughout the garden bed and take nutrients from the soil.
Pest and disease control
The worst enemies Strawberry mite and white spot are considered “Black Prince”. It's easy to spot them.
- With the appearance of the mite, the leaves of the plant begin to wrinkle, dry out and turn yellow. You can find it on the leaves white coating. Karbofos or colloidal sulfur saves you from ticks. A solution is prepared for processing: 8 grams of the substance per 10 liters of water.
- White spotting usually appears from excess moisture. Therefore, first of all, you need to regulate watering. As a preventive measure, you can treat with Bordeaux mixture. The disease first appears as red spots on the leaves, then their centers turn white and holes appear. You can get rid of spotting using Antracol (15 grams per 10 liters of water) or Ridomil-gold (25 grams per 10 liters of water).
In addition, the Black Prince variety can be affected by verticillium and common aphids.
- Verticillium can be cured only if the lesion is minor. For this, a 0.2% solution of Fundazol is used. In case of severe damage, strawberry bushes will have to be destroyed. To prevent this disease, before planting, the roots of the plant can be treated with “Potassium Humate” or “Agate 25K”.
- When infested by aphids, strawberry bushes should be sprayed with garlic or soap solution (60 grams per liter). To prepare the garlic solution, the cloves are squeezed out and the resulting juice is mixed with water. You can also add onion juice to the solution. If the number of aphids is insignificant, then you can get rid of them with your hands.
Preparing for winter
After harvesting, you need to remove old layer mulch, thoroughly weed the soil to remove weeds, loosen it, feed it with humus or vermicompost, and hill up the bushes a little. Closer to frost, it is recommended to cover the bed with pine branches or spunbond.
With proper care, the Black Prince strawberries will delight you with a tasty and abundant harvest for a long time.
Among the wide variety of garden strawberries, mistakenly called strawberries, it is worth highlighting several interesting and unusual varieties. A particularly promising variety that has recently appeared in the CIS is the Black Prince, with large, glossy, dark burgundy, almost black berries.
The history of the appearance of the Black Prince variety
The garden strawberry variety Black Prince was obtained from the nursery of the New Fruits company. This company is one of the producers of high quality planting material in Italy. The work of breeders from Cesene lasted ten years, the variety was tested in Ukraine and has proven itself well in Europe, as well as in many regions of Russia and Kazakhstan.
However, in some sources, early garden strawberries of the Polish selection Kama are passed off as this variety, which, due to its dark cherry berries, began to be incorrectly called the Black Prince.
Description of the variety
Garden strawberries Black Prince belong to the varieties of medium-early ripening. The first berries can be tasted in the third decade of June, and fruiting ends only at the end of summer. Young bushes with medium-sized dark green glossy leaves grow very quickly over time. Mature Black Prince bushes are taller than other varieties of garden strawberries. The flower stalks are tall and erect, but under the weight of the berries they can bend all the way to the ground.
The berries are truncated conical in shape, very large (weight - 50 grams), juicy, aromatic, and shiny. The color of the fruit is dark cherry, approaching black. The seeds are large, dark color, released on the surface of the fruit. The taste of the berries is sweet, with barely noticeable sourness.
The pulp is quite dense and does not contain voids, due to which the fruits are stored for a long time and tolerate transportation well.
It can be eaten in unlimited quantities even with diathesis, which is especially common in children. In general, there is a big paradox - strawberries are a very sweet berry, but they reduce the amount of sugar in the blood. Therefore, you can eat strawberries even if you have diabetes.

Young bushes of the Black Prince garden strawberry grow very quickly, producing a small number of runners. The Honey garden strawberry (left) is significantly smaller in size than the Black Prince (right). The berries of the Black Prince variety are large, dark cherry in color.
Characteristics of the variety
The variety has the following valuable qualities:
- long fruiting period - from June 20 to the end of August;
- high yield - more than 1 kg of berries per bush per season, 20–28 tons per hectare, the yield increases with age;
- large-fruited - the average weight of one fruit is 50 g, and the size of the berries does not change until the end of the season;
- excellent taste - juicy, sweet, and the berry itself is dense and aromatic;
- high transportability of berries and storage ability - up to 30 days when the temperature drops without loss of presentation;
- the viability and productivity of each plant is more than 5–7 years, with decent care- to 10;
- good frost resistance and the ability to withstand short spring frosts without harm to the crop;
- resistance to many diseases of garden strawberries.
But the Black Prince variety also has some disadvantages:
- average drought resistance - without watering the crop can withstand only a short period of time;
- does not take root well and grows on heavy soils, the roots rot even with good drainage;
- gives a small amount of runners and only 3-4 years, then you are left without planting material;
- is affected by strawberry mites, and in the fall anthracnose, as well as white and brown spots, may appear.

The best hydration option for strawberries is drip irrigation.
To extend the life of the bushes and get a rich harvest of berries High Quality, it is necessary to feed strawberries throughout the season.
In early spring, Black Prince strawberries need nitrogen (15–20 grams of urea per 10 liters of water), and during budding and flowering - phosphorus (30–40 grams of superphosphate per meter 2). During the fruiting period, it is good to feed the bushes with complex fertilizers such as Berries or Agricola (according to the instructions). They need to be added dry to the soil under the bushes or dissolved in water.
After collecting the last berries, you need to take care of the bushes again, this time for laying the harvest next year. Remove damaged dried leaves and old mulch, feed the plants, weed, water the beds with a weak solution of potassium permanganate. Keeping an eye on the weather, the bushes need to be watered periodically. Starting from the second year of life, the roots of the bushes are often exposed. In this case, they are covered with soil mixed with compost and watered (1.5 liters per bush).
