Fertilizing peppers in a greenhouse: what fertilizers to use

To ensure a good fall pepper harvest, the vegetables need favorable growing conditions. Peppers grown in greenhouses require special attention. The seedlings require regular feeding throughout their growth period. It's important to consider the requirements for soil fertility and vegetable growth. To do this, it is necessary to adhere to the dosage and timing of fertilizer application.

Basic rules for applying fertilizer to peppers

There are two ways to fertilize paprika: root and foliar. Here's the fertilizing schedule for sweet peppers:

1. You can fertilize the roots using nutrient solutions, dry granules, and humus in the form of mulch.
2. Foliar feeding is accomplished by spraying the leaves with a beneficial chemical. If fruit weight gain is slow, urea can be effective.
3. It is recommended to add nitrogen, potassium and phosphorus compounds to the soil in mixtures or separately.

Spraying should be done in cloudy weather to avoid leaf burn. Fertilize once every 14 days. If the soil is rich in beneficial micronutrients, the frequency of additional applications can be reduced to 3-4 times per season.

Feeding peppers in a greenhouse – this means a bountiful harvest. Paprika requires the following conditions:

1. The air temperature should be between 23 and 26 ^OWITH.
2. Humidity – the air should have a level of 70–75%.
3. Light – Peppers require ample sunlight to grow and fruit in a greenhouse. Without sufficient sunlight, they will grow slowly and produce weak fruit. To avoid this, it's recommended to plant peppers widely apart to avoid shade.
4. Soil composition – peppers prefer light soil with good organic matter. Clay soil is not suitable for paprika.

Fertilizers for peppers in a greenhouse should include mineral and nitrogen components.

Which fertilizers should I choose?

It's important for gardeners to feed their peppers at the right time to ensure they bloom and produce large, juicy fruits. You can use granular, liquid, or powdered fertilizers.

Fertilizers can be of the following subtypes:

• mineral based;
• organic substances;
• complex mixtures.

Let's consider each of the compositions separately.

Fertilizing peppers with urea is beneficial. It acidifies the soil when used in the right concentration. Typically, 30 g per bucket of water. Superphosphate, if used in granular form, is applied at 40 g per m.² soil. When using potassium-based compositions, they are calculated at 25-30 g per m².

Ammophoska is suitable, it contains:

• phosphorus;
• nitrogen.

Azofoska, a granular chemical containing potassium, phosphorus, and nitrogen, can be used. Commercially available formulations typically contain the following additives:

• magnesium;
• boron;
• zinc;
• copper;
• manganese.

They can be produced under the brands MacBor, Ferrovit or copper sulfate.

Organic fertilizers typically include manure, bird droppings, plant compost, peat, and green manure. Cow manure contains many beneficial substances. Peppers in a greenhouse can be fed with chicken or cattle manure, as well as rotted manure and compost.

Complex compositions include those containing the necessary components, balanced in the required concentration.

When planting peppers and at various stages of development, it's worth using folk remedies to nourish the soil. Suitable fertilizers for peppers during flowering and fruiting:

• herbal decoctions;
• ash;
• yeast;
• iodine.

It is important to feed the pepper during flowering and fruiting with several formulations per season.

As for ash, it is recommended to use it after burning:

• herbs;
• hay;
• straw;
• tree.

This makes it possible to feed plants with the necessary substances in a simple form.

To feed mature plants, other folk remedies are also helpful. For example, infused green grass is a good source of nitrogen, which sweet peppers love. It can be prepared directly in the greenhouse by finely chopping the tops, filling a barrel a third full with them, and adding water. Leave for seven days. Periodic stirring is recommended. Before use, dilute the infusion and water the roots, using half a liter of liquid per mature plant.

The iodine composition is optimal. If feeding peppers in a greenhouse, you can get sweet, juicy fruits, improving their flavor. Iodine tincture is purchased at a pharmacy and diluted with a bucket of water. Iodine is applied as soon as the first buds appear on the bushes. It is applied as a spray.

Peppers can be fed with yeast during flowering and fruiting. Some gardeners use dry bread instead. To make the infusion, take 10 g of yeast or 1 kg of breadcrumbs, pour a bucket of warm water over it, and leave it in a warm place for 2 days. To speed up the fermentation process, it's a good idea to add sugar or old jam. Add 2 parts water to the mixture and pour it under the plant.

Milk whey is a good fertilizer. It will nourish and boost the plant's immunity. Dissolve a cup of the whey component in 5 liters of water and spray it on the bush if the fruit has already begun to ripen.

When to fertilize peppers in a greenhouse

The first fertilizing of peppers after planting in the greenhouse should be done two weeks later. Subsequent fertilizing should be done at the beginning of flowering and before the peppers ripen. A break of 14 days or more is necessary to allow the plants to acclimate to the new growing and development conditions.

Top dressing is carried out according to the following scheme:

1. Water with diluted chicken manure, mulching the soil with compost. Fertilize with urea or ammonium nitrate at a rate of 40 g per bucket of water.
2. Peppers can be “fed” with phosphorus and potassium using ash or a mixture of superphosphate and potassium.

You can also use ready-made solutions sold in garden supply stores. After planting, as soon as the first buds appear, it's recommended to use herbal solutions or bread-based fertilizers. This will nourish the bush. To support bud bloom and prevent them from dropping, dissolve 10 grams of boric acid powder in a bucket of water. Use this solution as a spray.

The following compositions will promote abundant flowering:

• Ovary;
• Bud.

It's also beneficial to add a micronutrient solution. Pay particular attention to the pepper plants during the ripening period. Fertilize every 14 days. For proper care, alternately add herbal infusions, bread crumbs, 30 g of superphosphate, or 20 g of potassium sulfate to the soil, diluted in 10 liters of water. Potassium humate is also used at a rate of 1 g per 10 liters of water, using 1 liter per plant.

Eggshells and whey will help fertilize peppers after planting them in the greenhouse. Here are some tips for applying them:

• crushed eggshells will give the peppers a good amount of calcium;
• as soon as the fruits have ripened, milk whey is used, which will protect against fungus;
• Iodine is also used for disinfection purposes.

Any of these methods must be combined with standard care. For example, it's important to ensure timely staking and harvesting of vegetables. Proper staking will give the bushes a neat appearance and prevent them from overshadowing neighboring bushes. Pruning is also important: once the main stem begins to grow, leave two strong shoots and pinch out the remaining ones.

Mistakes in planting care

Peppers in a polycarbonate greenhouse should be fertilized at all stages of their development. However, many gardeners often make certain mistakes.

Common mistakes when growing peppers:

1. Oversaturating the bed with nitrogen. This will result in more vigorous ripening of fruits without setting fruit.
2. Applying fertilizer to dry soil will cause root and leaf burns.
3. Foliar fertilizers are often omitted during the cold season, when bushes require strong immunity and protection from fungus. This is especially important for bushes planted in the ground from seedlings.
4. Exceeding the amount of minerals added will lead to nitrate accumulation.
5. They don't monitor the amount of watering. Dry soil reduces the amount of boron supplied by the water. A deficiency will cause buds and shoots to wilt.

We recommend watching a video about the specific care needed when planting bell peppers.

All components should be applied according to the instructions, and general care should be based on the advice of experienced gardeners. Organic matter will increase fertility, improve soil quality, and replenish any necessary nutrients. To ensure your peppers receive sufficient nutrients for growth, carefully follow the recommendations of experts.
