I bought several tulips in containers that bloomed until late spring/early summer. The foliage is dead but still attached to the plant. The only water these plants have received has been from a recent rain. Are my bulbs still salvagable to store and use next year? If so, do I store them in the containers themselves or should I dig them up and store them in a paper bag with peat moss? I live in Lake Arrowhead, CA where we get several feet of snowfall each year.
