I grew wild strawberries (the small kind) on my balcony last summer.
The plants are supposed to be perennial, so I simply took the box
inside and let the plants and soil stand in the basement over the
winter (without any water or light). What are the chances that they
will start growing again if I just take them out again in the spring?

Probably not as great as if you had left them out all winter ;-)
