Establishment
4-8 weeks after plantingYoung plant is establishing root system and producing compact, low-growing foliage. Leaves are needle-like and green, gradually showing bronze tints.
Water consistently to keep soil evenly moist. Apply mulch around base (not touching stem) using pine bark or acidic compost. Protect from wind in first year.
Vegetative Growth
Spring through mid-summer, 3-4 monthsPlant develops bushy, compact form with increasing needle-like foliage. Foliage remains primarily green in spring and summer, becoming more bronze-tinged as temperatures cool.
Pinch back tips in spring to encourage bushier growth if needed. Maintain consistent moisture. Light fertilizing with ericaceous (acid-loving plant) fertilizer in spring.
Flowering
Late August through October, 8-12 weeksPlant produces abundant small, double pink flowers in dense spikes along stem tips. Blooms appear from late August through October. Foliage becomes increasingly bronze-red as temperatures drop.
Deadhead spent flowers to encourage continued blooming, though this cultivar's flowers persist ornamentally for extended periods. Maintain moderate watering.
Dormancy and Winter Interest
November through February, 4 monthsPlant enters dormancy with foliage fully transformed to bronze-red tones. Dried flower spikes remain on plant providing texture and structure through winter.
Reduce watering but do not allow soil to completely dry. No pruning or feeding during dormancy. Plant provides winter garden structure and color.
Spring Renewal
March through April, 4-6 weeksNew green growth emerges from base and along stems; foliage gradually returns to green as temperatures warm. Old flower spikes can be removed.
Prune lightly in early spring (March-April) to remove dead flower spikes and maintain compact shape. Do not cut into old wood. Resume regular watering and light feeding.
