in between the pots with soil to maintain moisture. Early bulbs, such as paper white narcissi and Roman hyacinths,will root sufficiently in a period of six weeks. It is much better, how-ever, to leave bulbs in storage for a period of eight weeks. Spanishiris bulbs require a longer period for the formation of root growththan most of the other bulbs. This group is probably the mostdifficult group to force successfully. They should remain buried inthe cold frame or in the pit, with all top growth retarded, until acomplete root system is established. When ample roots are formedand about one inch of top growth has appeared, it is time to lift allbulbs and remove them to a semi-dark cellar where they may be keptin a cool temperature with little light to encourage the immediatedevelopment of stems and foliage. Avoid, at this period, direct sun-light. After a reasonable amount of growth is secured, place the potswhere desired. Bulbs should be taken out of storage in relays toprovide a succession of bloom. |
