When to plant Daylily
Plant daylilies in early fall or early spring, when soil temperatures are moderate (Clemson). They tolerate planting almost any time of year, but those two windows give the best establishment.
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
