SEASONAL CARE
Spring Care:
Pinch back foliage in spring if you want to limit mature plant height. In mid-spring, remove old stems just above the new foliage, about 4 or 5 inches above ground level.
Summer Care:
Deadhead spent flowers to promote additional bloom.
Fall Care:
Sometimes a sporadic rebloom will occur in fall if plants are cut back in late summer after initial flowering period.
Winter Care:
Prune in late fall or winter, after plant goes dormant. To improve winter-hardiness, and encourage re-seeding, leave the stems intact over the winter. Cut back foliage to just above ground level in the fall after plants go dormant, or foliage is killed
