Establishment
First 6-12 monthsYoung transplant with developing root system and initial branching
Water regularly to keep soil consistently moist (not soggy). Mulch lightly with aged wood chips. Avoid fertilizer initially; let roots establish.
Vegetative Growth
Spring through autumn (or year-round in mild climates)Plant develops dense branching structure with needle-like evergreen foliage; leaves may show bronze tones
Maintain moderate moisture. Light pruning after flowering encourages bushier growth. No fertilizer needed; thrives in poor soil.
Flower Bud Formation
August-NovemberTiny flower buds form on branch tips during late summer and autumn, becoming visible as tight clusters
Do not fertilize with nitrogen-heavy fertilizers. Maintain consistent watering. Avoid pruning at this stage.
Flowering
December-March (peak winter blooming period)Abundant small bell-shaped crimson-magenta flowers bloom densely along stems, contrasting with bronze-tinted foliage
Flowers withstand frost and snow. Continue regular watering. Deadhead faded flowers after bloom finishes to encourage neatness and potential repeat flowering.
Post-Flowering & Renewal
March-MayFlowers fade; plant enters spring growth phase with fresh foliage development
Prune lightly after flowering to maintain compact shape and remove leggy growth. Cut back by no more than one-third of plant height.
