In general, for a start, you should think as carefully as possible about when did you last water your small and frail tomatoes, if it was relatively recently, then half the trouble, but if you do not remember when it was, then you should very definitely go and water them, do not worry about watering, if you you do it systematically, but if, on the contrary, you do it quite randomly, then your tomatoes run the risk of not growing at all and I will definitely have them in this support.
Because what kind of tomatoes will want to grow from a gardener who does not even water them, I hope you understand what exactly I am trying to tell you, everything it depends on you, my dear owners of great gardens, tomatoes could stop growing due to frosts, if suddenly you planted them early enough, of course, the scorching sun will not lead to anything good either, you better cover them with something and try to water them every day, strictly in the evening.
It is better not to water in the morning, because there will be little sense from this, because all the moisture will dry out for the whole day, and at night there is a possibility that the tomatoes will grow very well. Naturally, you could feed them with saltpeter, but it is also worth doing this in the evening and after watering, it will be very good and the tomatoes will undoubtedly begin to grow.
Let not by the hour, but by the day, but the less saltpeter will also add ovaries and make the trunks stronger, so most likely no wind will break them, I undoubtedly hope to your own and real attention to your tomatoes, which will undoubtedly help you achieve an incredibly good result, by which I mean a huge box of tomatoes.
