Establishment
First 12 monthsYoung plant developing root system; minimal vegetative growth in first year
Water regularly to establish roots; mulch around base; avoid fertilizing heavily in first year; stake if needed for support in windy locations
Vegetative Growth
2-3 yearsPlant produces new stems and foliage during spring and summer; growth accelerates in years 2-3
Prune immediately after flowering to shape plant and remove dead wood; apply balanced fertilizer in spring; maintain consistent moisture; thin crowded stems
Flowering
4-8 weeks depending on temperatureFragrant double yellow flowers emerge on bare branches in mid-winter (January-February in most regions), appearing waxy and papery
Do not prune during or just before blooming season; allow flowers to fully open before cutting for arrangements; fragrance is strongest on mild winter days
Post-Flowering
March-AprilFlowers fade and fall as foliage emerges; small elongated fruit may develop but rarely produces viable seed in double cultivars
Prune to desired shape immediately after flowering while still easy to see branch structure; remove any winter damage; fertilize with balanced formula
Summer Dormancy
May-NovemberPlant produces summer foliage; buds for next winter's flowers begin forming by late summer
Maintain consistent watering during dry spells; avoid excessive nitrogen fertilizer which reduces flowering; light pruning only if needed for shape
