Experts and BHG readers answer.
Daylilies not blooming
Daylilies shold be divided every three years. If you don't divide them regularly, they can slow down or stop blooming altogether. In addition, daylilies can bloom in dappled shade but partial shade might be too much for them. Divide them in the time after they would normally bloom - late summer or early fall - and move them to a sunnier spot.
