Sometimes summer residents who have transplanted healthy and strong tomato seedlings into open ground notice that their leaves have acquired a purple hue.
This can happen when the procedure was performed at an inappropriate time - it was too cold outside.
If effective measures are not taken to save the plants, they will unfortunately die.
To provide frozen seedlings with support, you should use any growth stimulator - "Epin", "Zircon" and others will do.
However, this is not enough - after the spraying is finished, water the beds with future tomatoes with the drug "Fitozont" or "Ribav-Extra".
The next step is to cover the tomatoes using spunbond. Please note: the covering material must be thick - its density must start from 60 g/sq. m.
After 3 days, organic matter should be applied to the beds - for example, a solution made on the basis of the "Biohumus" agent.
If the warm weather is not in a hurry to return, all the listed actions will have to be done again in a week.
Another important point is that it is not necessary to sharply warm the plants either. Do not rush to remove the shelter from them on the same day when the sun began to warm well.
