Pepper

Growth Types

Peppers have two main growth types:

Important: unlike tomato, pepper does not have true determinate forms, but there are varieties with limited growth (semi-determinate) (Wien and Stützel 2020).

Branching Pattern

Branching in pepper is dichotomous (forked): the main stem, after forming 8–15 leaves, splits into two, and each branch ends in a flower (Wien and Stützel 2020; Bosland and Votava 2012). Under optimal conditions, this branching continues to 5–6 orders.

This feature is important for understanding:

• How to shape the bush. Removing the first flowers stimulates the development of a more powerful bush.
• When fruiting begins. The first flower appears at the fork after a certain number of leaves (depends on variety and temperature).

Practical tip: to get a more powerful bush, remove the first flower (or first buds) — this stimulates the growth of side shoots and increases future yield. For varieties with small fruits (hot peppers), you can leave all flowers.

Flower Structure

• Corolla wheel-shaped (in most species) or bell-shaped (in some wild species).
• Flowers usually solitary (C. annuum) or 2–5 per node (C. chinense, C. frutescens).
• Flower color depends on species: white (C. annuum), white with yellow spots (C. baccatum), greenish-white (C. frutescens), purple (C. pubescens).

Flowering and Pollination

• Flowers open in the first half of the day and remain open for less than a day (Wien and Stützel 2020).
• The stigma becomes receptive already in the bud (before the flower opens) — this property is used by breeders for controlled crossing (Bosland and Votava 2012).
• Pollen remains viable for 3 days (Wien and Stützel 2020).
• Optimal temperature for pollination and fruit set is 16–21 °C at night and 20–25 °C during the day (Bosland and Votava 2012).

Why Do Flowers Drop?

Flower and bud drop is one of the most common problems when growing peppers. Main causes:

Practical tip: at high temperatures (above 30 °C), use shading and regular watering. In hot weather, spraying with water in the evening can help reduce the temperature around plants. At low temperatures, use covers.

Fruit Anatomy

The pepper fruit consists of:

• Pericarp (fruit wall) — the very "flesh" that we eat.
• Placenta — the internal tissue to which seeds are attached.
• Seeds, which are located on the placenta.
• Septae (walls) dividing the fruit into chambers (locules).

Important to understand: capsaicin (the pungent compound) is produced in the placental cells (Bosland and Votava 2012). Seeds do not produce capsaicin — they only sometimes become impregnated with it due to proximity to the placenta. Therefore, if you remove the placenta (internal membranes), the pungency of the fruit is significantly reduced.

Fruit Development

Fruit development goes through several stages:

1. Ovary formation — 35–50 days before ripening.

2. Fruit growth — the fruit increases in size, remaining green.

3. Technical maturity — the fruit has reached the size characteristic of the variety, but color is still green, white, cream, or light purple. At this stage, fruits can be harvested for consumption (especially sweet peppers).

4. Biological (physiological) maturity — the fruit colors to red, orange, yellow, or brown — this is effectively the onset of fruit senescence.

Fruit wall thickness — an important economic trait:

• In sweet varieties: 4–10 mm.
• In hot varieties: 1–3 mm.

Fruit Shape and Color

Pepper exhibits incredible diversity of shapes and colors:

Practical tip: do not pick fruits immediately when color changes — for maximum flavor, let them ripen on the plant for 3–5 days after color appears. However, for storage and transport, it is better to harvest at technical maturity.

Temperature Thresholds

Sources: (Wien and Stützel 2020; Bosland and Votava 2012; Tarakanov and Mukhin 2003)

Why Is Pepper So Sensitive to Temperature?

• When night temperature is above 24 °C, pollen formation is disrupted — it becomes sterile. Flowers drop, fruits do not set (Bosland and Votava 2012; Wien and Stützel 2020).
• At temperatures below 15 °C, fertilization processes slow down, pollen does not germinate. With prolonged cooling (below 10 °C), growth stops, and the plant may die.
• At temperatures above 35 °C, not only flowering suffers — respiration increases, the plant wastes energy, fruits become small and less sweet.
• Frost (even light, –1 °C) kills the plant — pepper does not tolerate sub-zero temperatures.

Practical tip: do not rush to plant seedlings in open ground. Wait until night temperatures are consistently above 15 °C. In regions with cool climates, use covers (spunbond, film) or grow pepper in greenhouses. In hot climates, shade plants during midday hours and provide adequate watering.

Differences Between Species in Heat Tolerance

Different pepper species respond differently to temperature:

Source: (Bosland and Votava 2012)

Practical tip: if you live in a region with a short summer, choose early-maturing C. annuum varieties (e.g., early bell, early sweet) or C. pubescens (rocoto) — they are better adapted to cool conditions.

Light Intensity

• For normal development, pepper requires intense lighting — at least 30–40 thousand lux (Tarakanov and Mukhin 2003). This roughly corresponds to a bright sunny day.
• With insufficient light, plants stretch, stems become fragile, leaves become smaller, flowering and fruiting are delayed, and ovaries drop.
• In shade, yield drops sharply, fruits become smaller.

Day Length (Photoperiodism)

Most pepper varieties are short-day plants. This means they begin fruiting earlier with a day length of 10–12 hours (Tarakanov and Mukhin 2003). However, modern varieties are often day-neutral and successfully fruit even with long days (16–18 hours) — this is the result of breeding.

Practical tip: in northern regions (where summer days are long), choose modern day-neutral varieties and hybrids. When growing seedlings in March–April (when days are still short), additional lighting is not required, but for strong seedlings in February, supplemental lighting is needed.

Water Needs

• Optimal soil moisture for pepper is 70–80% of field capacity (Wien and Stützel 2020).
• At soil moisture below 60% field capacity, growth slows, flowers and ovaries drop, fruits become small and bitter (Wien and Stützel 2020).
• At moisture above 85% field capacity, roots experience oxygen deficiency, leading to rot and fungal diseases.

Watering Features at Different Periods

Why Is Watering Regime Important?

• Moisture deficiency during fruit set leads to dropping of ovaries and flowers (this is one of the main causes of poor yield).
• Sharp moisture fluctuations cause fruit cracking and blossom-end rot (Wien and Stützel 2020).
• Waterlogging combined with high temperature promotes fungal diseases (late blight, root rots).

Practical tip: water pepper with warm water (not cold from the tap). In hot weather, water early in the morning or evening. Use drip irrigation — it provides uniform moisture without waterlogging. After watering, loosen the soil for air access to roots.

Air Humidity

Pepper prefers moderate air humidity — 60–70% (Wien and Stützel 2020). At high humidity (above 85%), fungal diseases develop and pollination worsens. At low humidity (below 50%), flowers may dry out and drop.

Practical tip: in greenhouses, ventilate regularly to reduce humidity. In open ground during dry hot weather, sprinkling (spraying with water) in the evening is helpful — this increases air humidity and lowers temperature.

Optimal Soil Characteristics

Sources: (Bosland and Votava 2012; Tarakanov and Mukhin 2003; Rêgo et al. 2016)

Which Soils Are NOT Suitable for Pepper?

Practical tip: before planting, conduct a soil test. At acidic reaction (pH < 5.5), add lime (dolomite flour) 2–3 months before planting. On heavy clay soils, make raised beds and add sand, peat, compost to improve structure. On light sandy soils, add more organic matter (compost, manure) to retain moisture.

Main Macronutrients

Source: (Rêgo et al. 2016)

Nutrient Removal with Harvest

When planning fertilization, it's useful to know how much nutrients pepper removes with the harvest (per 10 tons of fruit):

• Nitrogen (N) — about 30–40 kg
• Phosphorus (P₂O₅) — 15–20 kg
• Potassium (K₂O) — 40–50 kg
• Calcium (CaO) — 20–30 kg
• Magnesium (MgO) — 5–7 kg

Source: (Tarakanov and Mukhin 2003; Rêgo et al. 2016)

Micronutrients: Small but Important

Pepper is sensitive to micronutrient deficiency, especially boron, manganese, zinc, and molybdenum (Rêgo et al. 2016).

Practical Fertilization Schedule

During soil preparation (autumn or 2–3 weeks before planting):

• Organic matter: compost or well-rotted manure 4–6 kg/m² (or 30–40 t/ha).
• Minerals (per 1 m²): superphosphate 30–40 g, potassium salt 15–20 g.

Before planting seedlings (in the hole):

• Compost 1 handful.
• Superphosphate 10–15 g.
• Wood ash 1 tablespoon (source of potassium and micronutrients).

Fertilizing during the growing season:

Practical tip: do not overfeed pepper with nitrogen — this causes "luxuriance" and reduces yield. It's better to use complete fertilizers with equal or higher potassium content. Apply fertilizers in liquid form, combining with watering.

Drought Tolerance

Pepper is relatively drought-tolerant due to its powerful root system (especially with direct seeding) (Tarakanov and Mukhin 2003). However, with prolonged drought (especially during fruit set and filling), yield drops, fruits become smaller and more pungent (Bosland and Votava 2012).

Practical tip: in arid regions, be sure to use mulching (straw, grass, black film) to conserve soil moisture. Drip irrigation is the optimal irrigation method for pepper.

Salt Tolerance

Pepper is sensitive to soil salinity. At high salt concentrations (EC > 2.5 dS/m), growth slows, leaves get burned, and fruiting decreases (Bosland and Votava 2012). In arid regions with irrigated agriculture, this is an important factor.

Practical tip: if you use water with high salt content (e.g., from a well), try to combine it with rainwater, use drip irrigation (it reduces salt accumulation in the root zone).

Pepper Development Stages

Organogenesis Stages (Organ Formation)

For those who want to understand the plant more deeply: pepper goes through 12 stages of organogenesis (Meshkov et al. 2017). In simplified form, it looks like this:

1. Vegetative organ initiation — leaves and shoots form.

2. Transition to flowering — apical bud transforms into a flower bud.

3. Flower formation — sepals, petals, stamens, pistil appear sequentially.

4. Micro- and macrosporogenesis — pollen and egg cell maturation.

5. Flowering and pollination.

6. Fertilization and embryo development.

7. Fruit growth and ripening.

Practical meaning: understanding what stage the plant is at helps make the right decision. For example, nitrogen fertilization is needed before flowering begins (for vegetative mass accumulation). But potassium fertilization is most important from flowering through fruit growth.

Photosynthesis — The "Kitchen" of Yield

Pepper leaves are a factory for carbohydrate production. The larger and healthier the leaf apparatus, the greater the yield.

Features of pepper photosynthesis:

• Pepper is a C₃-type photosynthesis plant (like most vegetable crops). This means it works efficiently at moderate temperatures (20–28 °C) and good lighting (Wien and Stützel 2020).
• Photosynthesis intensity is maximal at 25–27 °C. When temperature rises above 32 °C, photosynthesis rate drops due to increased respiration (Wien and Stützel 2020).
• Pepper leaves maintain photosynthetic activity even during fruiting (unlike some other crops whose leaves senesce by season's end) (Wien and Stützel 2020).

Practical tip: do not remove healthy leaves unnecessarily — they feed the plant. Even during fruit ripening, leaves continue working and support fruit filling. If leaves yellow and die naturally, they can be removed, but do not rush to cut all leaves "to speed ripening" — this slows fruit filling.

Respiration — The Hidden Resource Consumer

Respiration is the process opposite to photosynthesis: the plant "burns" carbohydrates to obtain energy. In hot weather, respiration increases, and the plant spends a significant portion of photosynthesis products on it.

• At temperatures above 30 °C, respiration exceeds photosynthesis — the plant "consumes" its reserves, fruits do not fill, flowers drop.
• At high night temperatures (above 24 °C), nighttime respiration is especially intense, depleting the plant by morning.

Practical tip: in hot weather, try to reduce the temperature around plants (shading, watering, greenhouse ventilation). Good air access to the plant is also important for normal gas exchange.

How Assimilates (Photosynthesis Products) Are Distributed

1. During vegetative growth — most resources go to leaf and root development.

2. With the onset of flowering — resources begin to redistribute toward reproductive organs.

3. During active fruit growth — rapidly growing fruits become the main "consumers." They receive up to 70–80% of assimilates (Wien and Stützel 2020).

4. When fruits reach a certain size, their nutrient demand decreases, and resources are again directed to new ovaries and flowers.

Fruiting Cyclicity

It is because of competition for nutrients that pepper exhibits fruiting cyclicity (Wien and Stützel 2020; Tarakanov and Mukhin 2003):

• Rapidly growing fruits (about 3–4 weeks after set) "pull" nutrition toward themselves → new flowers and ovaries drop.
• When fruits reach maturity and their growth slows → a new wave of flowering and fruit set appears.
• The cycle repeats.

Practical tip: don't panic if flowers start dropping after the first wave of fruit set — this is normal. To smooth out the cyclic nature of fruiting, you can: - Regularly harvest fruits at technical maturity (not allowing them to overripen on the plant) — this "frees up" resources. - Provide good nutrition during the fruiting period. - If necessary, remove some ovaries at early stages to get larger fruits.

Why Flowers Don't Always Set

Even under favorable conditions, not all pepper flowers become fruits. Flower drop is a physiological defensive reaction of the plant when it cannot support all ovaries with nutrition (Wien and Stützel 2020).

Physiological mechanisms of flower drop:

1. Auxin-ethylene mechanism — under stress (heat, water deficiency), auxin synthesis in flowers decreases, sensitivity to ethylene increases → the flower separates from the pedicel and drops (Wien and Stützel 2020).

2. Decreased enzyme activity — under stress, invertase activity (an enzyme that breaks down sugars) in buds and flowers decreases, they receive insufficient nutrition → drop.

3. Assimilate deficiency — when rapidly growing fruits take almost all resources, new flowers are "starved" and drop.

Temperature Effects on Fertilization

Parthenocarpy: Fruits Without Pollination

Some pepper varieties can set fruit without pollination — this is called parthenocarpy (Wien and Stützel 2020). Such fruits are usually seedless or have underdeveloped seeds.

When this is important:

• In greenhouse conditions where there are no pollinating insects.
• In unfavorable weather (rain, strong wind, heat) when pollination is difficult.
• For obtaining an early harvest (parthenocarpic varieties often set faster).

Practical tip: if you are growing pepper in a greenhouse or in bad weather, you can help pollination — gently shake the plants in the morning when flowers are open. In large greenhouses, bumblebees are often used for pollination (Bosland and Votava 2012).

Two Stages of Fruit Growth

Pepper fruit growth, like many plants, proceeds in two stages (Wien and Stützel 2020):

1. First phase (about 3–4 weeks) — cell division. During this period, the number of cells that will make up the fruit is established. The more cells are formed, the larger the fruit will be. This stage is critically dependent on growing conditions.

2. Second phase — cell expansion (enlargement). The fruit increases in size through the stretching of existing cells and accumulation of water and nutrients.

What Determines Fruit Size

Fruit size is directly related to the number of seeds (Wien and Stützel 2020):

• The more ovules that are pollinated, the larger the fruit.
• Seeds release hormones (auxins) that stimulate pericarp (fruit wall) growth.
• If pollination was incomplete — the fruit grows small and deformed.

Practical tip: for large fruits, ensure good pollination (especially in greenhouses). If you have a large-fruited variety and fruits are small — the cause may be poor pollination or insufficient nutrition in the first growth phase (3–4 weeks after setting).

Fruit Quality: Sugars, Pigments, Capsaicin

During fruit ripening, important biochemical changes occur:

Source: (Bosland and Votava 2012; Wien and Stützel 2020)

Key fact: in hot and dry weather, fruits become more pungent! This is a plant defensive reaction (Bosland and Votava 2012).

Blossom-End Rot

Cause: calcium deficiency in developing fruits. This does not necessarily mean that there is little calcium in the soil. Often calcium is present, but the plant cannot deliver it to the fruit due to poor water supply or excessive shoot growth (Wien and Stützel 2020; Tarakanov and Mukhin 2003).

Symptoms: dark, sunken, rotting spot on the fruit tip ("blossom end").

How to prevent:

• Regular watering (without drying or waterlogging).
• Application of calcium fertilizers (calcium nitrate, dolomite flour).
• Avoid excessive nitrogen nutrition (stimulates leaf growth at the expense of calcium delivery to fruits).

Flower and Ovary Drop (Flower Abscission)

Causes (in order of frequency):

1. High temperature (above 30 °C) or low (below 15 °C) during flowering.

2. Moisture deficiency in the soil.

3. Competition with rapidly growing fruits.

4. Insufficient light (especially in greenhouses in winter).

5. Nutrient deficiency (especially phosphorus and potassium) or excess nitrogen.

What to do:

• Control temperature and humidity.
• Harvest ripening fruits to "free up" resources.
• Provide balanced fertilization (during flowering — phosphorus and potassium).
• Provide shade in heat.

"Luxuriance" (Excess Nitrogen)

Signs: vigorous, dark green leaves, very thick stems, few flowers and fruits.

Why it happens: excess nitrogen stimulates vegetative growth at the expense of generative growth (flowering and fruiting). This is because with high nitrogen content, the plant directs resources to leaf mass production (Wien and Stützel 2020; Rêgo et al. 2016).

What to do:

• Reduce nitrogen fertilization.
• Increase the proportion of potassium and phosphorus.
• In severe cases, apply foliar feeding with phosphorus.

Vitamin C (Ascorbic Acid)

Pepper is the champion among vegetables for vitamin C content (Bosland and Votava 2012).

• Vitamin C content in pepper reaches 150–250 mg per 100 g of fresh flesh (and in some varieties — up to 300–400 mg).
• For comparison: oranges — 40–60 mg, lemons — 40–50 mg.
• Just 30–50 g of red sweet pepper covers the daily human requirement for vitamin C (Bosland and Votava 2012).

Vitamin C changes during ripening:

• Green fruits have less vitamin C (100–150 mg/100 g).
• During ripening (coloring), its content increases 1.5–2 times.
• The peak of vitamin C content occurs at the red (biological) maturity stage (Bosland and Votava 2012).

Losses during processing:

• Canning and cooking lose up to 30% of vitamin C.
• Drying destroys vitamin C almost completely (Bosland and Votava 2012).

Practical tip: for maximum benefit, consume pepper fresh, raw. If you dry pepper for spices, remember that vitamin C is practically absent — but other beneficial substances remain.

Carotenoids and Provitamin A

The red, orange, and yellow color of pepper fruits is due to carotenoids — substances that are converted to vitamin A in the human body (Bosland and Votava 2012).

Source: (Bosland and Votava 2012; Tarakanov and Mukhin 2003)

The main red pigment of pepper — capsanthin — is found only in Capsicum fruits and nowhere else in any vegetable (Bosland and Votava 2012). Besides capsanthin, red fruits contain capsorubin, cryptoxanthin, β-carotene, and other carotenoids.

Practical tip: red and orange pepper are excellent sources of vitamin A. If you don't get enough carrots, diversify your diet with bright sweet pepper.

B Vitamins

Pepper contains almost all B vitamins (Bosland and Votava 2012):

Vitamin E (Tocopherol)

Red pepper is also a good source of vitamin E (antioxidant that protects cells from aging):

• Vitamin E content in red pepper — 3.7–5.0 mg/100 g dry matter (Bosland and Votava 2012).
• For comparison: spinach — about 2 mg, tomatoes — about 1 mg per 100 g dry matter.

Where Capsaicin Is Located

Most important fact for cooks and gardeners: capsaicin is produced in placental cells (the internal tissue of the fruit to which seeds are attached), not in seeds (Bosland and Votava 2012; Tarakanov and Mukhin 2003).

• Seeds can become impregnated with capsaicin due to proximity to the placenta.
• But if you remove the placenta (internal membranes), you can significantly reduce fruit pungency.
• There is very little or no capsaicin in the fruit walls (pericarp).

Culinary tip: if you accidentally added too much hot pepper but want to preserve the flavor — remove all internal membranes and seeds. Pungency will be significantly reduced, while the fruit's aroma and flavor will remain.

Chemical Nature of Capsaicin

Capsaicin is an alkaloid that irritates pain receptors (VR1 receptors) on the oral mucosa and skin. In response, the body releases endorphins — "happiness hormones," which creates a feeling of pleasure after eating spicy food (Bosland and Votava 2012).

Main capsaicinoids:

Source: (Bosland and Votava 2012)

What Affects Capsaicin Content

Source: (Bosland and Votava 2012)

Practical tip: want a hotter pepper — give plants slightly less water (within reason) and allow fruits to fully ripen on the plant. Want a milder flavor — water regularly and harvest fruits slightly earlier, at technical maturity.

Biological Significance of Capsaicin

Why does the plant produce pungent compounds? This is an evolutionary adaptation (Bosland and Votava 2012):

• Capsaicin repels mammals, which chew seeds and destroy them.
• Birds do not feel pungency, they readily eat fruits and disperse seeds over long distances — this is an ideal dispersal method.

Interesting fact: breeders use this feature. Varieties with small fruits that birds readily "peck" (chiltepin, piquin) often have very high pungency — nature has ensured that the fruit is interesting to birds rather than mammals.

Essential Oils — Pepper Aroma

Different pepper species and varieties have characteristic aromas determined by essential oils (Bosland and Votava 2012).

• More than 100 volatile aromatic compounds have been detected in pepper.
• The most famous is 2-methoxy-3-isobutylpyrazine, which gives the characteristic "green" smell of sweet pepper. Humans detect it at a concentration of 2 parts per trillion (Bosland and Votava 2012) — this is one of the most strongly scented substances in nature!
• In C. chinense species (habanero, scotch bonnet), fruity, floral notes predominate. In C. annuum — herbaceous, earthy, nutty notes.
• About 107 complex esters have been identified in C. chinense — which is why habanero has such a bright fruity aroma.

Practical tip: when choosing a variety, consider not only pungency and color but also aroma. For fresh salads, sweet C. annuum varieties with "green" smell are better. For sauces and seasonings — C. chinense with intense fruity aroma.

Fatty Oils

Pepper seeds contain up to 20–30% fatty oil (Bosland and Votava 2012), which is used in the food industry and medicine.

Mineral Elements

Pepper contains a wide range of minerals (Rêgo et al. 2016; Bosland and Votava 2012):

By Botanical Species (Taxonomic Classification)

This is the most scientific classification. It is based on the origin and genetic features of species, which we already covered in Chapter 1:

• Capsicum annuum
• Capsicum chinense
• Capsicum frutescens
• Capsicum baccatum
• Capsicum pubescens

Knowledge of the species helps predict the plant's requirements for heat, humidity, and season length.

By Fruit Shape and Type (Cultivar Group / Subtype)

This is the most common classification in horticulture. It groups varieties by fruit appearance and purpose (Bosland and Votava 2012; Eshbaugh 2012).

Below are the main cultivar groups most common in the world.

By Maturation Time

Practical tip: in northern regions, choose extra-early and early varieties, grow through seedlings, and be sure to check maturity dates on the package. In greenhouses, you can plant later varieties as well.

By Plant Height and Growth Type

By Use (Purpose)

Length of Frost-Free Period

Availability of Covers (Greenhouse, Cold Frame, Film)

• If you have a greenhouse — you can afford later and more finicky varieties (habanero, scotch bonnet, tall bell hybrids). The greenhouse also protects from wind and rain.
• If you only have open ground — rely on early and undemanding varieties that are resistant to temperature fluctuations.
• If you plan to grow on a balcony or windowsill — choose low-growing, dwarf, or ornamental varieties (they don't require large soil volumes and tolerate limited space well).

Practical tip: even in the temperate zone, you can grow late varieties if you use seedlings and temporary film covers. But this increases labor. For beginners, it's better to stick with early proven varieties.

Maturation Time (from Emergence to Technical Maturity)

Source: (Tarakanov and Mukhin 2003; Wien and Stützel 2020)

Growth Type and Plant Height

Important: in pepper, as in tomato, tall indeterminate varieties give longer fruiting but require more care (staking, shaping). For beginners in open ground, it's better to choose determinate or semi-determinate varieties.

Seedling Method (Recommended for Most Regions)

Why seedlings are almost always needed:

• Pepper has a long growing period (even for early varieties, 80–100 days from emergence to fruit).
• In most regions, direct sowing in open ground won't give the plant time for full development.
• Seedlings allow harvest 2–3 weeks earlier.

Seedling sowing timing:

• For temperate Russia and Belarus: late February – early March (for early varieties), mid-March (for mid-early).
• For southern regions: February.
• For northern regions: late February – early March, but with mandatory supplemental lighting.

Seedling growing features:

• Use loose nutritious soil (mix of sod soil, compost, peat, sand).
• Optimal germination temperature: 25–30 °C.
• After emergence, lower temperature to 18–20 °C day and 15–16 °C night.
• Prick out (transplant) at the 2–3 true leaf stage.
• Before planting, harden seedlings for 7–10 days.

Seedling age at planting: 50–65 days. Plants should have 6–8 true leaves and initial buds (permissible, but you can remove the first flower for better establishment).

Direct Seeding (Direct Sowing in the Ground)

When possible:

• In southern regions with a long warm season (southern Russia, Ukraine, Moldova, Central Asia, Caucasus).
• For early varieties with a short growing period.
• When using covers (film, spunbond) for early sowings.

Features:

• Sow when soil has warmed to 15–18 °C at a depth of 5–10 cm.
• Seeding depth — 1.5–2.5 cm.
• Seedlings appear more slowly than with the seedling method.
• Plants have a more powerful taproot system and tolerate drought better.

Practical tip: for most gardeners in temperate climates, the seedling method is the only reliable way to get a harvest. Don't risk direct sowing if your summer is shorter than 100–110 days.

Growing in a Greenhouse

Advantages:

• Protection from frost and strong winds.
• Longer season (can plant seedlings earlier and harvest until late autumn).
• Ability to grow late and finicky species (e.g., C. chinense).

Features:

• In the greenhouse, plants can reach 1.5–2.5 m (indeterminate varieties) — be sure to stake them.
• Maintain temperature within 20–28 °C day, 16–21 °C night.
• Be sure to ventilate the greenhouse to avoid overheating and high humidity (this provokes diseases).
• In hot weather, use shading and drip irrigation.

Growing on a Balcony or Windowsill

Who it's for:

• City residents without a garden.
• For growing early greens and a small amount of fruit.

Features:

• Choose dwarf or ornamental varieties with compact bush (height 30–50 cm).
• Use containers of at least 3–5 liters per plant (better 5–10 L).
• Provide good drainage.
• Place on south-facing windows or balconies with plenty of light.
• Rotate pots regularly for even lighting.
• Water moderately, fertilize every 10–14 days.
