It would help to know what kind of fern we are talking about; do you know the name and do you have photos? Thank you

|Unfortunately, spores do not grow like seeds do, and they require a lot more time and babying... if they grow at all. And, it is unlikely there are any spores left in the pot to begin with. You can google "growing ferns from spores" to get an idea of the process, but growing spores is a more advanced skill.
If there is even a single 1-2 inch long root left, there is a chance that it might regenerate into a plant. Plant the root horizontally, one-quarter inch deep and keep moist in the pot. You can seal the entire pot in a clear plastic bag so additional water would not be needed, but don't give it any direct sun or it will get too hot inside the bag. Keep it in the shade all the time. If anything grows, it will likely be 3-5 weeks before it emerges.
