Avoid moisture build-up by keeping bulbs in mesh or paper bags until you plant them. Dig individual holes for scattered bulbs, and prepare larger beds for mass plantings. Spade the soil eight to twelve inches deep and improve drainage if necessary by adding organic matter. Bulbs need a good source of phosphorus for strong, healthy development, so at planting time use a bulb fertilizer that is high in phosphorus and low in nitrogen. Wait until spring when green growth begins poking out of the earth before applying nitrogen.
Bulbs benefit then from a foliar feeding.
A good rule of thumb is to bury bulbs to a depth that is two and a half or three times their diameter. Use a trowel or a round bulb planter, whichever is easiest for you. Plant them with pointed ends up and roots, if you see any, facing down. Firm soil around the bulbs and water thoroughly. Keep the soil from completely drying out during extended dry weather.
