I bought potted tulips and daffodils back in the beginning of Spring and let them run their course. The foliage died back and I clipped it off, leaving the bulbs in the pots. My question is, should I leave the pots outside until the first frost then move them into my garage? I don't want to put them in the ground or store them outside of the pot. Will they grow again next Spring if I do this? Thanks!
