Establishment
Year 1Young shrub with minimal growth and no flowers; developing root system
Water regularly, mulch around base, protect from strong winds, avoid fertilizing to promote root development over leafy growth
Vegetative Growth
Years 2-4Shrub grows taller and wider, developing branch structure; leaves emerge in spring, drop in fall
Continue regular watering, light pruning to shape, apply balanced fertilizer in early spring, be patient as flowering may take 3-5 years
Flowering
6-12 weeks (winter)Double yellow flowers bloom on bare branches in winter (December-February); flowers are highly fragrant with papery petals
Do not prune while in flower; avoid cutting branches for arrangements if plant is young and still establishing; no fertilizer needed during dormancy
Post-Flowering/Leafing Out
2-4 weeks (late winter to spring)Flowers fade, fragrant blooms drop; new leaves emerge in spring, initially reddish, turning green
Resume regular watering as growth accelerates; prune immediately after flowering to shape and remove dead wood; this is the best time for heavy pruning
Summer Dormancy
June-NovemberShrub is fully leafed with lush green foliage; no flowers present; growth slows in peak heat
Water during dry spells, light feeding with balanced fertilizer in early summer, mulch to keep roots cool and retain moisture

Harvest Tips
