Site Selection and Soil Preparation for Blackcurrant

Light Regime

Blackcurrant is a light‑loving crop. Although some literature notes that it is more shade‑tolerant than redcurrant, this does not mean it can be grown in dense shade. With insufficient light, yields drop significantly, shoots become elongated, berries grow smaller, and fruit quality declines. The highest yields are obtained in areas with good sunlight throughout the day (Potapov et al., 2000). In shaded places, plants also become more susceptible to diseases and pests.

Practical takeaway: Allocate open, well‑lit areas for blackcurrant. Only slight shading during the hottest hours of the day is acceptable, especially in southern regions.

Wind Protection

Blackcurrant does not tolerate strong winds, especially drying winds (dry winds). Winds not only dehydrate the soil and damage shoots but also hinder bee flight, reducing pollination and fruit set. In winter, open windy areas promote freezing of shoots and flower buds. In southern regions with dry climates, winds can cause so‑called “winter desiccation” of shoots, where during thawing the wood evaporates more moisture than the roots can supply (Krivko et al., 2014).

Practical takeaway: Choose sites protected from prevailing winds—by natural or artificial windbreaks, buildings, or hedges. The distance from protective plantings to the bushes should be at least 6–8 m.

Terrain

For blackcurrant, level areas or gentle slopes with a gradient of up to 5–8° are preferred. The proper slope aspect is also important:

• In northern and central regions—south‑ and southwest‑facing slopes, which warm up better;
• In southern regions—north‑ and northwest‑facing slopes, where the risk of desiccation and overheating is lower (Tarasov et al., 1981).

Absolutely unsuitable:

• Lowlands and hollows where cold air stagnates—plants here suffer more from spring frosts, which can completely destroy flowers and ovaries;
• Areas with a high water table (less than 1–1.5 m)—blackcurrant roots cannot tolerate prolonged waterlogging and may rot (Potapov et al., 2000; Kurennoi et al., 1985).

Moisture Requirements

Blackcurrant is a moisture‑loving crop. This is because the bulk of its roots are located in the upper soil layer (up to 60 cm), and the leaf apparatus intensively evaporates water. The greatest need for moisture occurs during periods of active shoot growth, ovary formation, and berry filling. However, it is important to remember: currants do not tolerate stagnant water and excessive soil wetness (Dankov et al., 2015).

Practical takeaway: Choose sites with sufficient but not excessive moisture. When planting on heavy clay soils with poor drainage, measures must be taken to drain excess water.

Temperature and Winter Hardiness

In continental regions with stable snowy winters, blackcurrant can withstand temperatures down to –35 °C. However, in regions with frequent thaws (e.g., Leningrad Oblast), it can be seriously damaged by temperature fluctuations that cause bark and bud rotting (Dankov et al., 2015).

The optimal temperature for growth and fruiting is +18…+20 °C. In hot weather (above +30 °C), plants stop growing and may drop leaves even with sufficient moisture (Krivko et al., 2014). This is especially relevant for southern regions, where successful blackcurrant cultivation is problematic without irrigation and proper site choice.

Practical takeaway: In regions with hot summers, blackcurrants should be placed in areas with a cooler microclimate—foothills, northern slopes, near water bodies.

Soil Conditions

Blackcurrant prefers fertile, loose soils with good water and air permeability. The best mechanical compositions are light and medium loams, as well as sandy loams. Heavy clay and too light sandy soils are poorly suited for currants and require significant improvement (Krivko et al., 2014; Kurennoi et al., 1985).

The optimal soil acidity (pH) for blackcurrant ranges from 5.5 to 6.5, i.e., from slightly acidic to near‑neutral (Potapov et al., 2000). On acidic soils (below pH 5.5), plants are depressed, and nutrient uptake deteriorates.

Currants are sensitive to chlorine, so the use of chlorine‑containing potassium fertilizers should be limited (Kurennoi et al., 1985).

In the next section, we will discuss in detail how to choose a specific site for planting blackcurrant, what mistakes gardeners most often make, and how to properly evaluate a potential location.

Where Blackcurrant Can Be Grown

Climatic conditions. Blackcurrant grows well in temperate and cold climatic zones where the sum of active temperatures (above +10 °C) is at least 1300 °C and winter temperatures do not fall below –35 °C with snow cover (Kurennoi et al., 1985). The crop is successfully cultivated in the Non‑Black Earth region of Russia, Siberia, the Far East, the Baltic states, Poland, Germany, the UK, and New Zealand (Bowling, 2000). In southern regions, growing blackcurrant involves additional difficulties due to summer heat and dry air, but it is possible with proper site selection and irrigation (Krivko et al., 2014).

Topography and lighting. Ideal are:

• Level ground or gentle slopes with a gradient of up to 5–8°.
• In northern and central areas, south‑ and southwest‑facing slopes are preferred—they warm up and are better lit.
• In southern arid regions—north‑ and northwest‑facing slopes, where overheating and desiccation are less (Tarasov et al., 1981).
• The site should be open to the sun for most of the day. Light midday shade is only acceptable in the hottest regions.

Wind protection. Currants need protection from strong drying winds, especially in winter‑spring periods when they cause “winter desiccation” of shoots (Krivko et al., 2014). It is desirable that on the windward side there are windbreaks, hedges, buildings, or other barriers at a distance of at least 6–8 m from the plantings. However, the protection should not create shade.

Water supply. Since blackcurrant is moisture‑loving, the site must be provided with sufficient moisture—either from natural precipitation or through irrigation. At the same time, groundwater must be at a depth of at least 1–1.5 m from the surface (Potapov et al., 2000). Proximity to a water body or irrigation system is a big plus.

Soil conditions. The crop does best on fertile, loose, well‑aerated soils with a pH of 5.5–6.5. Light and medium loams, as well as sandy loams with sufficient organic matter, are optimal (Kurennoi et al., 1985). The soil must be structural, permeable, and moisture‑retentive at the same time.

Where Growing Is Undesirable

There are places where blackcurrant will be depressed, diseased, and give low yields or even die:

1. Lowlands, enclosed hollows, and foot slopes. Cold air stagnates here, increasing the risk of spring frosts that can completely destroy flowers. Moreover, water often stagnates in such places, which is detrimental to the root system (Bowling, 2000; Kurennoi et al., 1985).

2. Areas with a high water table (less than 1 m). Even short‑term flooding or rising groundwater to the surface causes root death due to lack of oxygen (Krivko et al., 2014).

3. Heavily shaded places—under tree canopies, near tall buildings, or solid fences. With insufficient light, shoots elongate, berries become smaller, yields drop sharply, and plants are more often affected by diseases (Potapov et al., 2000).

4. Open, windy sites without wind protection. This leads to soil and shoot desiccation, winter damage, and poor insect pollination.

5. Southern slopes in hot, arid regions. Here plants overheat and suffer from dry winds even with irrigation (Dankov et al., 2015). Such slopes are better allocated to more drought‑tolerant crops.

6. Soils with pH below 5.0—plants cannot absorb nutrients well, chlorosis appears, growth is suppressed. Also unsuitable are strongly saline and carbonate (alkaline) soils.

7. Heavy clay, slumping soils—they poorly transmit air and water, leading to root rot. Too light sandy soils—they dry out quickly and are poor in nutrients, requiring large investments for improvement (Krivko et al., 2014).

8. Areas where crops affected by verticillium wilt previously grew—potatoes, tomatoes, peppers, eggplants, strawberries, raspberries. Pathogens of these diseases can persist in the soil and infect currants (Potapov et al., 2000).

Typical Site Selection Mistakes

Experience of gardeners and agronomists shows that the most common mistakes when choosing a site for blackcurrant are:

Practical Recommendations for Site Evaluation

Before making a final decision, it is worth performing a small “diagnosis” of the chosen spot:

• Light observation: track how many hours a day the site receives direct sunlight in midsummer (preferably at least 6–8 hours).
• Determine topography and wind rose: assess whether cold air stagnates in spring and whether there is wind protection.
• Soil testing: use a simple pH tester or litmus paper to determine acidity; evaluate mechanical composition (roll a moist soil ball—sand crumbles, loam forms a ribbon, clay forms a tight ball).
• Water supply assessment: find out the depth of groundwater (you can dig a pit up to 1.5 m in spring); plan for irrigation availability.
• Site history: find out what grew there in the last 3–4 years and whether there were disease outbreaks.

Thus, when choosing a site for blackcurrant, you should be guided by its natural preferences—light, moisture without stagnation, wind protection, fertile loose soil. Ignoring these requirements dooms the gardener to constant struggle with problems and low yields.

In the next section, we will discuss which crops can be planted before currants and which are undesirable, as well as how to plan crop rotation and companion planting.

Why Predecessor Matters

Blackcurrant can grow in one place for 10–12 years or more; during this time, specific pathogens and pests characteristic of this crop accumulate in the soil (Kurennoi et al., 1985). If you plant currants immediately after crops with which they share common enemies, the plants will be suppressed from the first years of life.

In addition, different plants use nutrients from different soil horizons differently, leaving behind different reserves of elements and organic matter. A well‑planned crop rotation helps maintain fertility and improve soil health.

Best Predecessors

The most favourable predecessors for blackcurrant are:

1. Clean fallow—a plot kept without plants during the season, with periodic soil cultivation. This is the best option for improving soil health and accumulating moisture (Kurennoi et al., 1985; Krivko et al., 2014). In a garden setting, fallow can be a plot that was dug over and kept free of weeds all season.

2. Green manure crops (cover crops)—lupine, phacelia, white mustard, vetch, oats, rye. These plants enrich the soil with organic matter, improve its structure, suppress weeds, and improve soil microflora. Leguminous green manures are especially valuable, as they enrich the soil with nitrogen (Krivko et al., 2014; Potapov et al., 2000). Green manures are incorporated into the soil 1–2 months before planting currants.

3. Cereal crops—winter rye, oats, barley, wheat. They share no common diseases with currants, structure the soil well with their root systems, and leave organic residues.

4. Annual leguminous grasses—clover, alfalfa (in pure stands or mixed with cereals). These crops accumulate nitrogen, improve fertility, and enhance soil physical properties (Kurennoi et al., 1985).

5. Vegetable crops not belonging to the Solanaceae family—carrots, beets, dill, garlic, onion for bulbs, zucchini, pumpkin, early cabbage. Provided that excessive organic matter was not applied immediately before planting currants (Krivko et al., 2014).

In commercial fruit growing, crop rotations of 6–9 fields are recommended for blackcurrant, where currants occupy 3–4 fields during the fruiting period (Kurennoi et al., 1985). In amateur gardening, it is sufficient to follow the principle: do not return currants to the same place earlier than after 4–5 years.

Poor Predecessors

It is strongly discouraged to plant blackcurrant after the following crops:

1. Solanaceous crops—potatoes, tomatoes, peppers, eggplants. All are affected by verticillium wilt—a dangerous soil‑borne disease that also affects currants. Pathogens can persist in the soil for up to 3–4 years (Potapov et al., 2000; Krivko et al., 2014). In addition, these crops greatly deplete the soil and leave an unfavourable microflora.

2. Strawberries (garden)—share common pests and pathogens with blackcurrant, including verticillium, nematodes, and various rots (Kurennoi et al., 1985). Strawberries also heavily deplete the soil.

3. Raspberries—besides common diseases (verticillium, root rots), raspberries and currants compete for nutrients and moisture in the same soil horizons. Moreover, after raspberries, weeds that are difficult to remove often accumulate (Kurennoi et al., 1985).

4. Gooseberries—although belonging to the same family as currants, they share common diseases (powdery mildew, anthracnose, septoria) and pests (moth, sawflies, bud mite). Repeated planting of currants after gooseberries is unacceptable (Kurennoi et al., 1985).

5. Other species of currants (red, white, golden)—common diseases and pests, depletion of soil for a specific root system.

6. Perennial cereal grasses—although they do not share common diseases, their powerful root systems strongly dry and compact the soil, and the decomposition of sod in the first year after ploughing can inhibit young bushes (Kurennoi et al., 1985). If the plot was under perennial grasses, high‑quality sod preparation and fallowing are necessary.

Crop Rotation in the Amateur Garden

In a small garden plot, it is difficult to organize a full multi‑field crop rotation. However, you can follow minimal rules:

• Do not return currants to the same place earlier than after 4–5 years.
• Between plantings of currants on the same plot, grow crops that do not share common diseases (cereals, green manures, most vegetables).
• Try not to place currants after crops listed as “poor predecessors”.
• When preparing the soil, add organic matter and green manures to restore fertility.

In an industrial‑type crop rotation for the Non‑Black Earth zone, the following scheme is recommended (Kurennoi et al., 1985): 1 – black fallow (autumn planting of currants); 2–3 – young currants; 4 – currants entering fruiting; 5–9 – fruiting currants; 10 – annual grasses, row crops, winter rye. Although such a long rotation is not feasible in an amateur garden, the principle of crop alternation should be observed as much as possible.

Allelopathy – Influence of Neighbouring Plants

Allelopathy is the ability of plants to release chemical substances into the environment that can stimulate or inhibit the growth of other plants. For blackcurrant, this has practical significance.

Undesirable neighbours:

• Walnut, Manchurian walnut—release juglone, which inhibits many garden crops, including currants. Currants cannot be planted near these trees (Tarasov et al., 1981).
• Fir, spruce, pine—their coniferous litter and root exudates can acidify the soil, which is unfavourable for currants.
• Sea buckthorn—has a powerful root system that actively competes for moisture and nutrients; moreover, its root exudates can inhibit neighbours.
• Raspberries and blackberries—not only due to common diseases but also because of strong competition for resources, especially for moisture in the upper soil horizon.
• Gooseberries—besides common diseases, these plants compete for nutrients in the same horizon.

Favourable neighbours:

• Onions and garlic—release phytoncides that suppress the development of some fungal diseases, including powdery mildew. They can be planted near currants or in the inter‑rows (Krivko et al., 2014).
• Dill, calendula, marigolds—their smell and exudates attract beneficial insects and repel some pests.
• Peas, beans, broad beans—enrich the soil with nitrogen and do not compete with currants for nutrients; their root system is deeper than that of currants.
• White clover—as a ground cover between bushes, it can enrich the soil with nitrogen and suppress weeds.

It is important to remember that neighbouring should not create shade—tall crops or trees should be at least 3–4 m away from currant bushes.

Practical Recommendations

1. Plan the site in advance. If you are just developing the plot, think about where in a few years you can plant currants, considering crop rotation.

2. One year before planting, sow green manure (mustard, phacelia, vetch with oats) on the chosen site and incorporate them into the soil.

3. If you are forced to plant currants after a “poor” predecessor, carry out thorough soil treatment (deep digging, adding organic matter, liming if necessary, and using biological preparations for soil disinfection).

4. Consider neighbours—do not plant currants near walnuts, conifers, or vigorous trees.

5. In the inter‑rows, you can grow onions, garlic, calendula, marigolds—they will help improve the health of the plantings.

In the next section, we will examine in detail the soil requirements of blackcurrant and methods for rapid soil diagnostics.

Optimal Soil Parameters for Blackcurrant

Based on many years of research and practical experience, the following optimal soil characteristics for blackcurrant have been identified (Kurennoi et al., 1985; Potapov et al., 2000; Krivko et al., 2014):

These parameters ensure the root system has access to water, air, and nutrients. Recall that the bulk of blackcurrant roots are located at a depth of 10–40 cm, so the topsoil layer should be the most fertile and loose (Dankov et al., 2015).

Why These Parameters Are Important

Mechanical composition. Currants prefer soils where roots can develop freely and access oxygen. In too heavy clay soils, roots suffer from lack of air, water stagnates, leading to rot. In too light sandy soils, moisture and nutrients quickly leach away, and plants suffer from lack of water and nutrition (Krivko et al., 2014).

Acidity. At pH below 5.0, many nutrients (phosphorus, potassium, calcium, magnesium) become unavailable to plants, while aluminium and manganese become toxic. At pH above 7.0, iron, manganese, and other micronutrients become less available, leading to chlorosis. The optimal pH range of 5.5–6.5 ensures maximum availability of all nutrients (Westwood, 1993).

Humus. Soil organic matter (humus) is a source of nutrition, a structure improver, and a regulator of water regimes. High humus content makes soil more loose, moisture‑retentive, and fertile. With insufficient humus, soil compacts, dries out faster, and plants are less well supplied with nutrients.

Rapid Soil Diagnostics You Can Do Yourself

Before establishing a currant plantation, it is useful to assess the soil condition on the chosen site. A full agrochemical analysis is better ordered from a specialised laboratory, but some important parameters can be determined independently.

Table of Diagnostic Results Interpretation

What to Do with Non‑Optimal Indicators

The good news is that soil can be improved. However, it is important to remember: soil preparation should begin 1–2 years before planting currants so that the added amendments have time to take effect.

If the soil is too acidic—apply liming materials (dolomite flour, slaked lime, chalk) under autumn ploughing. The dose depends on acidity and mechanical composition. On light soils, liming materials are applied in smaller doses, on heavy soils—in larger doses. Liming must be done before applying high doses of organic matter.

If the soil is too heavy—add coarse sand, organic fertilizers (manure, compost, peat), and carry out deep cultivation.

If the soil is too light (sandy)—add clay (claying) and large doses of organic fertilizers that help retain moisture and nutrients.

If the soil is poor in organic matter—apply manure, compost, green manures. The rate of organic fertilizer application for currants is from 100 to 150 t/ha (i.e., 10–15 kg per 1 m²) (Kurennoi et al., 1985).

In the next section, we will move on to actual soil preparation: what, when, and how to do to create the best conditions for blackcurrant.

General Scheme of Preparatory Work

Ideal soil preparation for blackcurrant includes the following stages:

1. Clearing the site of weeds, especially perennial rhizomatous ones (couch grass, sow thistle, bindweed)—1–1.5 years before planting.

2. Sowing green manures (if desired or necessary)—one year before planting.

3. Application of organic and mineral fertilizers—3–4 months before planting.

4. Deep ploughing or digging (up to 40 cm) with loosening of the subsoil—1–2 months before planting.

5. Discing, harrowing, and levelling the surface—2–3 weeks before planting.

6. Repeated herbicide treatment (if necessary)—immediately before planting.

Let’s examine each stage in detail, taking into account the soil diagnostic results.

1. Clearing the Site of Weeds

Perennial weeds (couch grass, field sow thistle, field bindweed, dandelion) not only compete with currants for moisture and nutrients but can also serve as reservoirs for diseases and pests. For example, viral diseases such as cucumber mosaic virus can be transmitted from weeds to currants via nematodes (Westwood, 1993). Moreover, powerful weed rhizomes complicate soil cultivation and bush care.

Control methods:

• Mechanical: repeated digging or discing of the site during the season to exhaust rhizomes. Effective but labour‑intensive and not always 100% successful.
• Chemical: treatment with non‑selective herbicides (e.g., glyphosate‑based – Roundup and analogues). The optimal time is active weed growth (spring – early summer) 1–1.5 years before planting. Application rates according to the product instructions (Krivko et al., 2014). Usually 1–2 treatments per season.
• Combined: in autumn – herbicides, in spring – deep ploughing with mouldboard turnover, then repeated herbicide treatment on regrowing weeds.

Important: herbicides must fully decompose in the soil before planting currants (usually 2–4 weeks, depending on the product).

2. Sowing Green Manures (Cover Crops)

This practice is especially useful on low‑fertility, sandy, or heavy clay soils. Green manures enrich the soil with organic matter, improve structure, suppress weeds, and fix nitrogen (legumes). Recommended crops (Krivko et al., 2014; Potapov et al., 2000):

• Legumes: lupine (best on acidic soils), vetch, peas, clover, alfalfa.
• Cereals: oats, rye, barley.
• Brassicas: white mustard, oil radish – suppress weeds well and improve soil health.

Technology: green manures are sown in spring or late summer, 1–2 months before the main ploughing. They are mown and incorporated into the soil during digging or ploughing. Sowing rates according to recommendations for the specific crop. On a currant plot, green manures can be used in a fallow field, leaving the soil as black fallow after incorporating the green mass.

3. Fertilizer Application

The main fertilizer is applied once (for the entire life of the plantation) under deep ploughing. Doses depend on soil fertility and the results of agrochemical analysis (see previous section).

Organic fertilizers. On soils with low humus content (light, sandy, low‑fertility), the rate is increased; on chernozems and cultivated soils, it is reduced.

Rates of manure or compost application (Kurennoi et al., 1985):

• on poor soils – up to 100–150 t/ha, i.e. 10–15 kg/m²;
• on medium‑fertility soils – 40–60 t/ha (4–6 kg/m²);
• on well‑cultivated soils – 20–30 t/ha (2–3 kg/m²).

In garden plots, it is convenient to apply well‑rotted manure or compost into planting holes (8–10 kg per hole) or spread evenly over the surface and incorporate. However, it is important that organic fertilizers are well rotted; otherwise they can cause root burn.

Mineral fertilizers. The main elements for blackcurrant are nitrogen (N), phosphorus (P₂O₅), and potassium (K₂O). Approximate doses (in kg of active ingredient per hectare) for medium soil fertility (Kurennoi et al., 1985; Potapov et al., 2000):

• Phosphorus: 90–120 kg P₂O₅/ha (ordinary or double superphosphate).
• Potassium: 90–120 kg K₂O/ha (potassium sulphate, potassium magnesia; chlorine‑containing forms (potassium chloride) should be used with caution or in autumn so that chlorine is leached from the root zone by spring).
• Nitrogen: during pre‑planting preparation, nitrogen is usually not applied (it is given as top dressing in the first years). But if the soil is very poor, 30–40 kg N/ha (ammonium nitrate, urea) can be applied 2–3 weeks before planting.

For amateur gardeners, doses per 1 m²: approximately 30–40 g of superphosphate and 20–30 g of potassium fertilizer (chlorine‑free) per 1 m², incorporated to a depth of 20–25 cm.

Liming. If soil pH is below 5.5, liming is necessary. Doses depend on acidity and mechanical composition. Approximate rates of dolomite flour application (in g/m²) to bring pH to 6.0 (Krivko et al., 2014; Westwood, 1993):

Liming materials are applied well before planting (preferably 1–2 years), thoroughly mixed with the soil to the depth of the topsoil.

4. Deep Soil Cultivation

The goal is to create a deep, loose root zone, improve aeration, water permeability, and incorporate fertilizers to the depth where the bulk of roots are located (10–40 cm) (Kurennoi et al., 1985).

• On soils with a deep topsoil horizon (more than 30 cm) – ploughing with a mouldboard plough to a depth of 30–35 cm (in the garden – digging to a spade depth with soil turnover).
• On soils with a shallow topsoil layer (less than 20 cm) – ploughing to that depth while simultaneously loosening the subsoil by 10–15 cm (using a ripper, chisel, or manually – digging to two spades with loosening the bottom) (Kurennoi et al., 1985; Potapov et al., 2000).
• On heavy clay soils – in addition to organic matter, add coarse sand (1–2 buckets per 1 m²) and carry out deep loosening to improve drainage.
• On sandy soils – add clay (claying) and organic matter; cultivation is shallower, but with mandatory mulching later.

Important! Fertilizers are applied before ploughing, not just in planting holes, so that roots have access to nutrients immediately after growth begins. If you plant currants in individual holes, fertilizers are thoroughly mixed with soil in the lower part of the hole, and a layer of clean soil is placed on top so that roots do not touch the fertilizers.

5. Levelling and Soil Preparation

After ploughing, the surface of the plot must be carefully levelled and loosened. This is necessary for mechanical planting, convenient irrigation and care, and to prevent water stagnation. On garden plots, rakes, hoes, and flat cutters are used. On larger areas – disc harrows, drag harrows, levellers (Potapov et al., 2000).

It is important that after cultivation there are no large clods and that the surface is slightly mulched (fine‑crumbly). This improves water permeability and reduces evaporation.

6. Final Weed Control

Immediately before planting (2–3 weeks), a weed provocation can be done – surface loosening to stimulate seed germination, then their destruction by cultivation or herbicides. This reduces weed infestation in the first years of the plantation (Krivko et al., 2014).

Specific Preparations Depending on Soil Type (Summary Table)

Accelerated Soil Preparation (If Time Is Short)

Sometimes a gardener decides to plant spontaneously, and a year‑long preparation cycle is not possible. In such cases, accelerated preparation can be done:

1. Carefully remove weeds manually or with herbicides (2–3 weeks before planting).

2. Apply organic fertilizers (well‑rotted manure or compost) into planting holes (8–10 kg per hole), thoroughly mixing with soil.

3. Apply phosphorus‑potassium fertilizers into holes (30–40 g superphosphate and 20–30 g potassium sulphate per hole).

4. If the soil is acidic – add dolomite flour to the holes (100–200 g per hole, mixed with soil), but the effect will be incomplete; it is better to carry out liming in the first years of the plantation (around the trunks).

5. Dig the site to a spade depth, removing weeds.

6. Plant currants, but in the first year pay special attention to irrigation and top dressing.

However, such “accelerated” preparation is less reliable and should ideally be avoided by planning plantings in advance.

Mistakes in Soil Preparation

1. Applying fresh manure immediately before planting – causes root burn and plant death. Organic matter must be well rotted.

2. Applying fertilizer only in the planting hole – roots quickly grow beyond the hole and encounter unprepared, poor soil. It is better to treat the entire area, not just the holes.

3. Ignoring acidity – planting on acidic soil without liming leads to chronic chlorosis, weak growth, and low yields.

4. Insufficient cultivation depth – roots cannot develop in the compacted subsoil, resulting in weak bushes.

5. Surface application of fertilizers – they do not reach the root zone and are ineffective.

In the next section, we will answer the most frequent questions from gardeners about site selection and soil preparation for blackcurrant.
