Care Recommendations

Maintenance Level:

Low

Fertilizer:

Not necessary. do not over-feed; a fall top dressing of compost is all they need to flourish. Too much high nitrogen fertilizers will shorten their lifespan and make the plants floppy.

Mulch:

Sandy/gravelly mulches will protect plants and help avoid onset of rot.

Water deeply but rarely, make sure soil is well-drained, do not cut back in fall, prune in spring

Long Term:

Winter:

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

Spring:

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:

Deadhead spent flowers to promote additional bloom.

Fall:

Sometimes a sporadic rebloom will occur in fall if plants are cut back in late summer after initial flowering period.

General Care Comments:

Needs exceptional drainage, allow soil to dry out between waterings, give full sun, deadhead in summer
