How to grow peppers in a greenhouse? When to plant and how to care for them?

Growing peppers in a greenhouse allows you to get a bountiful harvest even in regions with an unstable climate. However, the wrong choice of variety, errors in planting and care can lead to low productivity and plant diseases. Let's look at the main stages of growing peppers in a greenhouse, including choosing a variety, preparing the soil, proper watering and fertilizing.
Choosing a greenhouse: what parameters are important?
Peppers are demanding of temperature and humidity, so the greenhouse should provide stable conditions. It is important to consider:
- Cover Material: Best suited polycarbonate, as it retains heat, protects from wind and distributes sunlight evenly. Film can also be used, but requires frequent replacement and is less resistant to temperature changes.
- Shape: Optimal arched or a gable greenhouse, which provides good ventilation and air circulation, preventing plants from overheating.
- Height: Not less than 2-2.5 meters to ensure optimal conditions for growth and ease of working with plants.
- Availability of vents and ventilation: Peppers are sensitive to overheating and high humidity, so it is important to have vents and a system for regulating air circulation.
- Drip irrigation: Maintains stable soil moisture and prevents over-watering, which is especially important for greenhouse conditions.
Expert advice: When choosing a greenhouse, pay attention to the presence of automatic vents. They will help to avoid overheating of plants, especially in hot weather.
When to plant peppers in a greenhouse?
Planting times depend on soil and air temperature:
- Heated greenhouse – planting is possible as early as the end of March.
- Unheated greenhouse – planting is carried out in mid-April – early May, when the soil temperature is stable at +15°C.
Preparing seedlings:
- The seedlings are planted at the age of 55-70 days, when the plant has 5-6 true leaves.
- 10-14 days before planting, the seedlings are hardened by lowering the temperature and reducing watering.
- Before planting, it is recommended to treat the roots with growth stimulants (for example, “Kornevin”) for rapid rooting.
Expert advice: Never plant pepper seedlings in cold soil - this will lead to slow root development and weakening of the plant.
Soil preparation
Pepper loves fertile and loose soil with neutral acidity (pH 6.5-7).
How to prepare the soil:
- Cleaning the greenhouse – Removing old plants and disinfecting the soil (treatment with a solution of copper sulfate 1 tablespoon per 10 liters of water) will help get rid of pathogens.
- Adding organic matter – Compost or humus (5-6 kg per 1 m²) will improve the structure and nutritional value of the soil.
- Adding ash – 200 g per 1 m² (source of potassium and phosphorus) will reduce soil acidity.
- Improving the soil structure – Adding peat or sand will ensure good aeration of the roots.
- Mineral enrichment – Superphosphate (30 g per 1 m²) and potassium nitrate (20 g per 1 m²) will help plants develop faster.
Expert advice: Sow green manure (mustard, lupine) in the greenhouse two weeks before planting. This will improve the soil structure and protect it from diseases.
Choosing a Pepper Variety
Suitable for greenhouses:
- Early ripening varieties: “Latino F1”, “Claudio F1”, “Kakadu”.
- Mid-season varieties: "Atlant", "California miracle", "Buyan".
- Large-fruited varieties: "Bogatyr", "Orange Miracle".
- Hybrid varieties: They are more resistant to diseases and produce a stable harvest.
Expert advice: Choose varieties with resistance to viral diseases (for example, Claudio F1) to reduce the risk of plant infection.
Diseases and pests
Common diseases:
- Late blight – Brown spots on leaves, rotting of fruits.
- Treatment: Spray with copper sulfate (1 tablespoon per 10 liters of water).
- Verticillium wilt – Leaves begin to turn yellow and fall off.
- Solution: Treat the soil with biofungicides (Trichodermin).
- Mosaic - Mottled leaves, stunted growth.
- Control: Remove infected plants, treat with Fitosporin.
Expert tip: Inspect plants regularly and remove affected leaves to prevent the spread of infections.
Growing peppers in a greenhouse
Growing peppers in a greenhouse requires following all the stages – from choosing the right variety to optimal watering and fertilizing. It is important to control the temperature, humidity, provide the plants with nutrients and protect them from diseases.
Key points:
- Choose greenhouses with good ventilation and sufficient height.
- Use warm, fertile soil with added organic matter.
- Observe optimal planting times and temperature conditions.
- Feed plants regularly and control humidity.
- Don't forget about bush formation and disease prevention.
