At what temperature can tomatoes freeze?

Temperature norms for planting tomato seedlings in open ground.

Content

The tomato is a very heat -loving culture, and does not tolerate cooling. Therefore, it is necessary to carefully and with great attention to the temporary standards of planting seedlings in open ground. In this article we will tell you what temperatures can withstand tomatoes and how to prevent their freezing.

Features of quenching tomato seedlings before planting in open ground

In most cases, the landing of tomatoes in open ground begins from the beginning of May to its end. It all depends on the characteristics of the climate of a particular region and the average daily temperature. According to this, temporary standards for seed sowing are selected to obtain seedlings. Most often, seed sowing is carried out about 50-60 days before the transfer of seedlings directly into the open ground. Accordingly, if the landing is outlined on May, it is necessary to plant seeds in the month of March.

Instructions:

To do this, the seeds are poured with cold water for several minutes. The seed that surfaced is thrown away. And the seeds that sank to the bottom are nourished by moisture, leave.
Further, for 2 hours, seeds are pulled in a weak solution of potassium permanganate. All this can harden the seeds, make them more resistant to adverse temperatures and climatic conditions.
After you get seedlings, from the end of April, it will be necessary to take pots with seedlings on the street, for about an hour and a half. It is from such a time that it is necessary to harden the seedlings of tomatoes, and gradually renew until the open air all day.
This is necessary if there are no significant temperature changes and climatic indicators are at a constant level for a long time.
Such manipulations will help to harden tomatoes, make them more resistant to transplanting to the ground. After the constant temperature begins to stay at + 15 for a week, you can plant tomatoes into the ground. The soil temperature at this time should be + 12.
Please note that the air warms up much faster than the soil, therefore, respectively, on the street it should be warmer than +12. Planting is carried out on a cloudy day. Even the most hardened and stable cultures of tomatoes feel bad if they are planted during the heat, they simply fade.

At what temperature can tomatoes freeze?

After planting tomatoes, it is necessary to cover them overnight for a week with plastic bottles. This will help maintain the temperature at a higher level than the temperature of the soil. If you tempered tomatoes, endured seedlings for several weeks per street for the whole day, then this kind of culture can withstand a decrease in temperature to + 5. Some tomatoes experience small frosts on the surface of the soil quite well if they were tempered.

What to do if you purchased seedlings in the market? In this case, we advise you to analyze the temperature norms. The fact is that most often seedlings purchased on the market are not stable and, with the slightest temperature differences, it simply wins. To prevent this from happening, purchase seedlings for landing at a time when the threat of frost on the surface of the soil will completely disappear. There is a constant temperature at +18 degrees in the daytime. That is, at night the temperature should not drop below +5 degrees, otherwise you risk losing tomato seedlings.

If, nevertheless, you bought seedlings a little earlier than the specified time, and doubt that there will be no frost at this time, then you can do the following. We recommend pulling an impromptu guy over tomatoes. In the daytime, the film can be removed, and pulled at night. Such manipulation will protect tomatoes from wilting and freezing.

How to restore frozen tomatoes?

There are several ways:

The whole black part is cut off
Drawing shelters are built over planting
Before that, steaming bonfires from the tops, dry mullein are diluted along the perimeter of the beds. This smoke will warm seedlings
Feeding by humans and watering urea is carried out
Shelters are left for a week until the tomatoes will recover

As you can see, there is no clear temperature at which tomatoes freeze. It directly depends on the stability of the seedlings and on whether you really tempered tomatoes and prepared them for reduced temperatures and adverse climatic conditions.
