Q.Why are my tomato plants wilting from being transplanted to larger pot
The plants are inside, and they were doing wonderful, so because it is still very early here I transplanted the beautiful plants to larger pots using an organic soil with good things in it. They were fine for the 1st couple days, then I noticed the leaves had wilted and some of them look like they will die. Why? They were doing fine! Could the soil I used in the new pots be too rich?

They are probably just suffering from transplant shock, which is normal. This article will help: https://www.gardeningknowhow.com/plant-problems/environmental/learn-how-to-avoid-and-repair-transplant-shock-in-plants.htm
