After scooping, the mother bulbs are put in trays and placed in the sun for about a day for the purpose of drying the freshly cut surfaces. (Fig. 7.) The trays are then placed in a propagating house where ventilation and light can be controlled (fig. 8), where a temperature of from 75° to 90° F. is maintained. Sometimes sand, ashes, or air-slaked lime are dusted over the freshly cut surface to assist in absorbing the moisture caused by scooping out the base of the bulbs before they are placed in the propagating house. The scales soon separate somewhat, callus, and produce young bulblets. If the mother bulbs are scooped soon after harvest (say at some time in July) and properly handled, they should produce a fine lot of baby bulbs by planting time in October. (Fig. 9.). Fig. 9.—Mother hyacinth bulbs that have developed an excellent crop of young bulb- lets. If properly handled, the mother bulbs at the time of planting should resemble the two bulbs shown above. The time required to mature bulbs by this method is from four to seven years, depending more or less upon the variety, the size of the bulblets, and the conditions under which they are grown. Scoring is the second most important commercial method of propa- gating hyacinths. By it fewer but larger and stronger bulblets are produced. On this account the smaller and poorer mature bulbs are generally selected for scoring. The process consists in making from two to four cuts across the base of the bulb, depending upon its size, and extending through to about its center. The fewer the cuts, as a rule, the fewer and larger the bulblets. (See fig. 4.) The process of scoring kills the flower and growing point, and the strength of the bulb that would have been used in producing a plant and flowers is utilized in the production of baby bulbs, the same
