Do not bloom the tomatoes in the greenhouse: why and what to do, poor care

Do not bloom the tomatoes in the greenhouse - with such a problem every can come up. Why tomatoes in the greenhouse have ceased to bloom is a question that can puzzle any person who breeds tomatoes. This problem must necessarily be solved, because if there are no flowers - there will be no harvest. To take some action to eliminate the trouble, you need to find out the reasons why this happens, and start from this.

Why tomatoes do not bloom in the greenhouse: the main causes of the phenomenon

The reasons why tomatoes become badly blossom may be mth. As a rule, this is due to the fact that the tomato is missing something. So, the main reasons for this are:

• Low air temperature( below +15) or soil - if there is not enough heat for the plants, they can not only discard their color, but also die;
• In a greenhouse it is too hot - at a high temperature( above +30) the conditions for tomato growth are also difficult;
• Increased or decreased soil or air humidity - as a rule, this overflow of plants is either not sufficient;
• No pollination - if in the open ground conditions, this happens naturally, then in the greenhouses it is necessary to pollute the flowers artificially.

Tomatoes may not bloom if the hot room is very hot in the greenhouse.

The optimum temperature to be maintained in the greenhouse is 20-25 degrees.

If the plant has too massive stems and leaves, but no flowers or they are very weak - the main sign that the plant is cold. And if the leaves are curled, the tops dry, and in addition the ground cracked - the tomato lacks moisture.

Very bad bloom of tomatoes in the greenhouse: what affects this

In addition to the main factors that affect the growth of flowers in tomatoes, there are additional.

Tomatoes can not flow well due to various diseases

These include:

• Too much planting of the cuttings - the sun can not penetrate to the roots due to the leaves hiding the soil;
• Lack of phosphorus or potassium - occurs if plants do not fertilize;
• Nitrogen saturation - appears in case of "overfeeding" of tomato with manure;
• Growing tomatoes from their seeds;
• Various diseases;
• Treatment of plants with pesticides.

It happens that the stems just do not have enough strength to form the ovary. Such a problem may be in the case of prolific varieties or those that yield large tomatoes.

Tomatoes do not blossom in the greenhouse: what to do and how to fight

After finding out the reasons for which tomatoes do not bloom, you can begin to eliminate them.

What you need to do for this:

• It is compulsory to correct the temperature if the problem is in it - during cold nights it is necessary to warm the greenhouse well( oven-stoves or conventional heaters will help);
• To increase air humidity and reduce temperature, you can pour cold water on the paths in the greenhouse - but do this only in the morning so that condensation does not appear;
• You can raise the temperature by a few degrees by watering tomatoes with warm water( provided that it fell to +15 on the street);
• All plants need fresh air - if the street is warm, the greenhouses need to be ventilated, and if the constant outdoor temperature - +20 - +26 doors can be left open all night;
• If the problem is in the absence of pollination( the pollinated flower usually has open and deflected petals) - it is necessary to do it artificially or to attract bees by putting pots with honey-colored flowers in the greenhouse;
• In case if nothing helps, you need to remove all the available vapors - thus, the plant will direct its forces to the formation of a new ovary.

As soon as the reason for not blooming tomatoes is clarified, it is necessary to immediately begin to eliminate it.

Watering tomatoes should ensure that the water is not too cold, otherwise the plant roots will freeze and the ovary will not.

What if tomatoes "overeat" vitamins?There are several ways to solve the problem:

• Carry out root and foliar top dressing with phosphate fertilizer;
• Remove part of the foliage, especially the one that covers the roots from the sun and interferes with normal air circulation;
• Thoroughly ventilate the greenhouse;
• For a while, stop watering the plants.

"Overfed" tomatoes can be recognized by large fleshy leaves and a weak ovary.

By the way, some hybrids can not bear fruit at the subsequent cultivation. When buying, you must carefully read the information on the package.

Tomatoes do not bloom: gardeners' faults and preventative measures

It happens that not only external factors provoke the absence of flowering on tomatoes, but the summer residents themselves for inexperience or ignorance make a number of mistakes.

The most common of these are:

• Cultivation of some hybrids from own seeds - such tomatoes will not be tied;
• Treatment of plants with pesticides when they bloom;
• The wrong location of the greenhouse and as a result lack of heat;
• Too much seedling planting - the plants should not interfere with each other's development.

In order to prevent the weakening of flowers in tomatoes, they need the right care:

• In case of appearance of various insects or fungal formations on the leaves of the plant, you must immediately begin to fight them;
• You do not need to "fertilize" plants with nitrogen fertilizers, when they blossom - it is better to do this after the flowers appear;
• For tomatoes to have enough vitamins, before flowering, you need to make top dressing with double superphosphate and potassium sulfate, adding each substance to 15 grams in a bucket of water.

If the hothouse is not heated, then it is better to wait until the seedlings are planted, as long as there is a risk of returning the colds.

To avoid the weakening of flowers in tomatoes, they need the proper care.

The most comfortable conditions for the dwelling of tomatoes are:

• 60% air humidity in the greenhouse;
• +20 - + 25 - optimum temperature of air;
• Abundant watering a couple times a week of plants in the flowering phase;
• Frequent loosening of soil and mulching of soil.

Watering tomatoes should only be done under the root so that water does not fall on its other parts.

As you can see, problems with color can be for a variety of reasons, ranging from external factors and ending with the errors of truck farmers. However, everything is fixable. The main thing is to determine the source of the plant's discomfort correctly. You can hedge and plant several types of tomatoes, which differ in their resistance to climatic conditions. In this case, you can even get an empty ovary from one variety, get a crop from another.
