When to plant tomatoes in the ground?

Tomato is a tasty and healthy vegetable, and there is no summer resident who does not grow tomatoes on his plot. Moreover, this matter is not at all complicated. Most gardeners grow seedlings themselves, and some buy them from greenhouses and private owners. When to plant tomatoes in the ground? The seedlings are ready for planting when they reach the age of 60-65 days. But the timing of when to plant tomatoes in the ground depends not only on the age of the seedlings, but also on climatic conditions. Until the threat of night frosts passes, even if the weather is warm and sunny during the day, seedlings cannot be planted; they will die at the first frost.
What to do if the spring is cold, the warmth does not come, and the seedlings are stretched out? Still can't plant it. When the warmth finally arrives, the elongated seedlings are planted “lying down”, falling asleep almost to the very top of their heads. For tomatoes, it is better to choose a sunny, elevated place. Before planting, the seedlings need to be watered abundantly, removed from the container along with a lump of earth and planted in a pre-dug hole, which is then filled up. It’s even good if you bury the tomatoes deeper than they were buried in the seedling container, they will develop a more powerful root system.
In different regions of our country, warmth comes at different times in spring. In the middle zone, the threat of frost remains until June 5-6, so tomatoes are usually planted in the ground on June 7-11. I often plant at the end of May, but I cover them at night with several layers of covering material, and after June 10 I stop covering them.In my opinion, this way they take root better and get sick less. If you plant tomatoes when it is already hot during the day, they will get sick for a long time.
