Fertilizers for Bulbs. No fresh manure should ever touch abulb, but well-rotted manure may be incorporated deep in the soilbefore planting with the best of results. The manure should be ac- cessible to the feeding roots but be kept away from the bulb. Do notuse manure at all unless the bed is excavated to a depth that makesit possible to spade the manure in below the level on which the bulbsare to rest. Tulips are less apt to be injured by manure than arenarcissi. For planting with a trowel or dibble, bone meal only shouldbe used. Leaf mold and sand should be added to heavy soils. Bonemeal used with bulbs tends to increase the size of the blooms. Liquidmanure, added liberally when the plants are budding, has often givenexcellent results. To increase the development of new bulblets andespecially of gladioli, a fertilizer containing a large percentage ofpotash is desirable. |
