Dig it out. Once the spring blooming is done the tuber (a type of bulb) will go dormant but first all the leaves will turn yellow and make an unsightly mess. If you can store the bulb with foliage attached in a spot with dry soil all summer you can replant it in the fall. Of all the spring blooming bulbs, only daffodils make more of a mess than ranuculus once they are done flowering. Keep growing, Marianne Binetti
