Establishment
3-6 monthsYoung plant developing a compact, spreading habit with fine needle-like foliage
Water regularly to establish roots; mulch lightly with bark chips; avoid transplanting; protect from harsh winds in first year
Vegetative Growth
Spring through summerShrub expands horizontally and vertically, foliage becomes denser and more robust
Pinch tips in early summer to promote bushiness; maintain consistent moisture; light feeding in spring with acid-loving plant fertilizer
Flowering
8-12 weeks, depending on temperatureDense clusters of small bell-shaped flowers appear along stems in winter (December-April depending on cultivar and region)
Do not deadhead all flowers if you want winter color; some varieties benefit from light pruning after peak bloom; ensure good drainage to prevent flower bud rot
Post-Bloom
Late spring through early summerFlowers fade but persistent seedheads and fine foliage remain attractive; plant maintains evergreen structure
Light pruning can be done immediately after bloom to maintain shape and encourage next year's flowers; do not prune into old wood
Dormancy
Late summer through fallGrowth slows in late summer and fall; foliage may deepen in color as temperatures cool
Reduce nitrogen feeding; maintain moderate moisture; do not heavily prune; prepare for winter bloom cycle
