Why peppers don’t bloom in a greenhouse: we determine the cause of the problem and get rid of it

Peppers just don’t bloom, even though everything is done according to technology? Many gardeners face this situation. The article describes the main factors and possible causes of this problem, and defines the sequence of actions to obtain a good harvest. Let's also consider preventive measures and advice from experienced gardeners who have dealt with this problem.

The main factors due to which sweet and bitter peppers do not bloom in greenhouses

Peppers are one of the most capricious vegetables when it comes to growing. Their buds break off and fall, their fruits do not grow or do not ripen. First of all, you will need to get rid of the reasons why peppers do not bloom and provide them with a comfortable existence in the greenhouse.

Factors to be addressed:

1. Lack or excess of light. It is best if there is sufficient lighting in the greenhouse, but it is light for no more than 12 hours. It is fluctuations up or down that lead to the loss of flowers.
2. Violation of temperature in the greenhouse. Peppers like warmth, but not extreme heat. Temperatures above 30 °C are destructive for this crop, but temperatures below 20 °C are not suitable for it, the buds will fall off.
3. Soil quality. If the soil is depleted, it is unlikely that you will get a good harvest. To grow decent fruits, you need to nourish the soil with phosphorus or nitrogen fertilizers, the main thing is not to overdo it, so as not to get the opposite result.After planting the pepper seedlings in the greenhouse, we fertilize it for the first time with a solution of manure and water in a ratio of 1:10 l, the second fertilizer is a mixture of chicken manure and superphosphate, a ratio of 1:12. If the soil is properly fed, the inflorescences will remain in place and will lead to a good harvest.
4. Choosing a location on the site and excess water. In order not to get into trouble and then transplant seedlings from place to place, it is better to immediately determine the south side of the area where the light falls the most and where there is no acidic soil with a lot of moisture. This crop loves moisture, but not to such an extent that water stands in the beds. Ideal conditions are if the area is well ventilated and there is no underground groundwater or bodies of water nearby.

These are the main reasons why peppers do not bloom. They apply to both sweet pepper seedlings and hot peppers. And remember: the bitter pepper was planted separately from the sweet pepper and quite distantly. Otherwise, during pollination, the varieties may mix, and the result will not be what you expected. The fruits of sweet peppers will be bitter.

Grows but doesn't bloom

If you have ruled out all the factors listed above and the peppers do not grow, do not bloom, or bloom but do not set, then you have done something wrong. Why else do peppers bloom and set poorly?

There are several reasons for this situation:

1. You overfed the soil with fertilizers, and the seedlings began to “float with fat”. In this situation, thick and lush greenery grows without flowering. Do not use universal plant tinctures, otherwise the pepper will forget about its true purpose and will not grow the fruits you expect.
2. It happens that the seedlings have blossomed, but there are no ovaries, and if there are no ovaries, there will be no fruit. This happens because there is no pollination.Pollination does not occur when the humidity in the greenhouse is high. This is due to the fact that the pollen sticks together and the pistils and stamens do not meet. Pollination will also not occur if it is too cold or too hot, less than 12 °C or more than 30 °C.
3. Frosts and long periods of cold weather. In this case, get greenhouse heaters and maintain the recommended temperature around the clock.
4. Watering with cold or cool water. It is recommended to heat the water temperature for irrigation to 25 °C; this is the optimal temperature for peppers.
5. Do not leave the first buds on seedlings that ripen immediately after planting. The plant will begin to favor flowers and will not produce additional shoots. The first buds need to be picked.

To get a good harvest, avoid the above conditions.

What to do to make peppers bloom

So, the factors that adversely affect peppers, as well as the reasons why they do not set and do not bloom, have been clarified. But what to do to get a rich harvest of this capricious crop?

The sequence of actions is as follows:

• plant seedlings when the soil temperature at night no longer drops below 13 °C;
• place the beds in places with light shade so that the illumination is optimal - pepper loves light;
• Distribute the seedlings among themselves and plant them at a distance of half a meter from each other - do not create a cluster, let them grow;
• apply fertilizers that contain an equal balance of potassium, phosphorus and nitrogen;
• loosen the soil no deeper than 3–5 cm;
• plant different varieties separately and far from each other.

By following these recommendations, you will enjoy the fruits of this crop from your greenhouse all winter.

Prevention measures

Follow preventive measures:

• inspect the seedlings and always the root zone every day;
• If you see slight darkening at the roots, immediately treat with a weak solution of potassium permanganate;
• thin out densely overgrown shoots;
• do not treat with fertilizers during the flowering period - do it before or after; in general, you can fertilize the soil up to 5 times during the season;
• keep an eye on insect pests, if any appear, the fight must begin immediately - use the products “Keltan”, “Karfobos”, “Strela” depending on the type of insect (aphids, slugs, mites);
• the optimal temperature in greenhouses around the clock will help avoid the greenhouse disease - Alternaria, which occurs due to sudden temperature changes. It is characterized by dark brown spots and water stains already on the fruits. If the situation arises, a solution of copper oxychloride with water, a ratio of 40 g of the substance per 10 liters, or a solution of Bordeaux mixture, a ratio of 100 g per bucket of water, will help to correct the situation.

By following preventative measures, you will be rewarded with a good harvest.

Advice from experienced summer residents

Experienced gardeners share tricks that will make the season go well:

1. Plant other plants between the rows that will safely get rid of pests - coriander, calendula, parsley, basil. In addition, parsley and coriander will interest pollinating insects.
2. Apple peels and banana skins are good lures for pollinators.
3. During the growing season, you need to trim off excessively elongated branches and shoots that are shaded. Nothing will grow on them.
4. If you pick ripe fruits more often, new fruits will form and the harvest will be richer.
5. Observe the sowing period. Seeds should be planted not in February, but in mid-March. Plant in February, the plant will “age” ahead of time.
6. It is better to sow sprouted seeds. Place the seeds on a cotton pad moistened with water, cover with the cotton pad, place in a saucer and wait for germination. If necessary, spray with water. You can add a growth stimulator - HB101 or aloe juice. After three to four days, the seeds can be planted.
7. Plant no more than 2 seeds exclusively in individual dark containers.
8. It's standard not to dive! Otherwise, seedling growth will stop for two weeks. It's better to do this:
   • option one is to immediately plant the crop in 500 ml containers, so picking will not be required;
   • option two is to sow the seeds in small cups or peat tablets and then transfer them to larger containers, without touching the root system at all, and bury them with soil.

Conclusion
