If large blooms are desired, purchase the larger bulbs. The feel of the bulbs indicates their quality. Healthy bulbs are firm. Softness indicates dead tissues and a flower bud inside the bulb that may be barely alive. If planting will be delayed, store the bulbs in a dry area below 65 degrees.
High temperatures damage the flower buds.
Plant bulbs in well-drained, sandy soil with maximum exposure to sunlight. Plant in clusters with individual bulbs four to five inches apart. Before planting, work the soil to a depth of 12 inches. Set the bulbs firmly in the ground and press out any air pockets that develop in the soil.
