A delicate plant is the strawberry

I have been taking care of tropical strawberries for 2 years now and it was usually good. Some plants died maybe due to old age or too much fruiting. But this time, there are young plants that look dying. They are like baby plants taken from the mother plant and transplanted to the pots for convenience. After 5 days the leaves started to wither.

I am a backyard farmer and I should know what is happening to my baby plants. But I admit that I do not know why the new plants are dying. Now it’s been more than 2 weeks that they are in the pots and they can be considered dead. Sad but I have to be aware.
