Narcissi are best left undisturbed for several years. It is best toallow crocuses and early tulips to run out, unless the tulips are wantedfor formal effects. All tulips, like hyacinths, yield most satisfactorybloom if they are taken up annually and replanted at the proper season.Only the larger bulbs should be planted, where uniformity of effect is
desired, while the smaller ones may be planted apart by themselvesto increase in size. Late tulips often do very well undisturbed for three,four, or five years.
Crocuses, squills, and narcissi may be naturalized, especially if care istaken not to cut the tops too closely or too soon after blooming. Thisis one of the strong arguments in favour of planting crocus bulbs inSeptember. The tops will have then matured before spring mowingbegins.
