Plan to dig, separate, store and replant in fall
As years pass, clumps of daffodils, narcissus, jonquils and hyacinths become crowded, resulting in smaller flowers. Shrunken flowers mean it’s time to dig and replant. Wait until after all of the foliage has died back to the ground.
Mark the location and flower color of clumps to be divided before all the foliage is gone. Make a large plant label and stick it in the middle of the clump.
