Q: Our established daylilies were hit with a string trimmer. They are now little 2″-3″ stumps. What can we do to help keep them alive? 

A: If the daylilies were healthy before they were damaged, I would expect them to come back just fine next year. They may not produce much new growth this fall but the roots in the ground should have plenty of energy to make new leaves next spring. Fertilize twice each year, in March and May.
