They do need warmth to start them off, you could try potting them up in new dry compost.
The tiny ones, have you lifted them to see if they have tiny white roots on the bottom. Even my ones that just live outside in tubs all winter are up now. If you buy them again, go for bigger ones, they stand a better chance and rarely fail.
Go to your garden centre, choose ones that have a really good defined indent And of a good size. If they havent rotted, they may still come.
I can see now that I didnt actually say keep them indoors I am very sorry about that.
