Why tomatoes are not tied in the greenhouse, what to do in such a situation, we will consider in detail in this material. It is clear that first you need to establish the cause of this phenomenon, and then take concrete measures to solve it.
Tomatoes are vegetables that are demanding of certain conditions. In particular, it is important for them to choose the right soil, to observe the necessary level of humidity, also pay attention to the quality of the greenhouse. The reason that all the ovaries fall off may be hidden, including in the absence or excessive amount of fertilizing, as well as in poor lighting of the greenhouse. Well, as you can see, the question is serious and multifaceted, everything needs to be sorted out in order.
Pollination of tomatoes
This is probably the first logical suspicion that arises in a gardener if there are no ovaries on his beautiful and lush bushes of tomatoes. For the normal formation of a flower, pollination is necessary and, if this is not an acute issue when growing tomatoes in open ground, then in the greenhouse it is necessary to pay extra attention to it. It is clear that in the greenhouses there are no insects, wind or rain, which are directly involved in the pollination process.
Be sure to have air vents in your greenhouse that, if necessary, can be opened. When the buds begin to form on the tomatoes, it is necessary to open the windows periodically, providing access to the greenhouse not only to insects, but also just to the breeze. To increase the attention of insects, you can bring a few pots of fragrant and sweet flowers into the greenhouse.
Advice! If the greenhouse is very large, it is recommended to keep a hive with bees inside. But this is true most often for industrial tomato growing conditions.
How to achieve natural pollination in a certain period:
1. Shake the flowers yourself so that the pollen wakes up on the pistils.
2. Turn on the fan in the greenhouse, which will provide air movement, and that, in turn, will transfer pollen from plant to plant.
3. Carry pollen yourself. To do this, you can use a brush or cotton wool.
Temperature, air humidity
Why do not set tomatoes in the greenhouse, what should I do? The temperature conditions of this plant may have been violated. Please note that for the normal development of the fruit, the air temperature should be in the range of 20-25 degrees Celsius. At the same time, tomatoes love a temperate, humid climate, but warm.
If for a long time the air temperature in your greenhouse is below the mark of 15 degrees Celsius, then pollen simply cannot ripen. Keep your greenhouse warm enough. If the temperature is more than 30 degrees Celsius, the pollen loses its sterility, and the greenhouse heats up very much. To lower the temperature, the greenhouse should be ventilated.
Humidity is also important. If it is elevated, then various diseases that the fungus causes will develop on the tomatoes. Pollen will stick together and fall in lumps. Dry air will prevent the pestle from growing.
Important! Pay particular attention to soil moisture. It should be normal and tomatoes will tolerate short-term drought well. But during the flowering period, watering should be regular so that the flowers do not fall. If the leaves are curled, and the tops of the bushes are drooping - this is a sure sign that urgently need to water the tomatoes.
About top dressing
Why tomatoes are not tied in the greenhouse, what to do in a situation where there are any doubts about properly applied top dressing. If there are too many or too few trace elements in the soil, the ovaries will not form. With frequent fertilizers, the fruit can have a lot of nitrogen, which will cause the flowers to change their appearance and the fruits will not form at all.
If you take here is a fertilizer, going overboard with him will be difficult. It affects most plants very well and helps them grow faster and better.
Very often, the ovaries fall due to a lack of nitrogen or phosphorus in the soil. Be sure to periodically, according to a strictly defined scheme, superphosphate should be added to the soil.
According to what scheme is it right to fertilize tomatoes (calculation is taken for 10 liters of water):
1. After two weeks, introduce complex fertilizer nitrophosphate.
2. After a dive, after another 2 weeks, add a tablespoon of superphosphate and potassium sulfate.
3. Already after planting in the ground, the first top dressing should be carried out a week later, simply by watering the bushes with a weak solution of potassium permanganate. Then, after two weeks, add 20 grams of ammonium nitrate, and after another week carry out root dressing on the leaves based on 10 grams of superphosphate, 10 grams of urea and potassium sulfate.
These are the main points why they are not tied. tomatoes in the greenhouse. What to do in each case, you need to navigate the situation. Be sure to establish the reason, you need to understand exactly how to act, how to change the conditions for keeping tomatoes in order to get an excellent harvest from each bush.
