Good drainage is essential. Bulbs may stop blooming if they become overcrowded or shaded too heavily. Sparse blooms on daffodils can be caused by planting too shallowly. If leaves are cut off too soon in spring, the bulb may not store enough food to bloom the following year. Many varieties of bulbs will not produce flowers a second year in Southern climates.
Animals often dig and eat tulip and crocus bulbs during the winter.
They rarely eat daffodil bulbs. The only sure way to protect bulbs from animals is to enclose the bulbs in wire mesh when planting. In general, jonquil hybrids, tazetta hybrids, poeticus and species daffodils will grow reliably throughout South Carolina. Many will not perform well in warmer parts of the state. Plant daffodils 6 to 8 inches deep, less for smaller species bulbs.
