Establishment
Spring to early summer, 4-8 weeksYoung transplant with thin stems and emerging leaves; root system developing in soil.
Water consistently to keep soil moist but not waterlogged. Shelter from harsh winds if in exposed sites. Mulch around base to retain moisture.
Vegetative Growth
Spring through summer, 12-16 weeksRapid stem and leaf expansion; plant developing its characteristic narrow foliage with glossy appearance and fragrant resinous coating.
Maintain consistent moisture. No fertilizer needed in poor soils; avoid over-fertilizing. Prune lower branches if desired for tree-like form.
Catkin Formation
Early spring, 2-4 weeksSmall catkins appear on branch tips in early spring before leaves fully emerge; flowers are inconspicuous but important for pollinators.
No special care required. Catkins appear annually in early spring. Allow them to develop for wildlife benefit.
Dormancy
Late fall through early spring, 4-6 monthsPlant loses leaves in fall; enters winter dormancy with bare branches. Resinous buds are visible and aromatic when crushed.
No watering needed once soil freezes. No pruning in late fall (prune after winter or early spring instead). Inspect for winter damage.

Harvest Tips
Harvest aromatic leaves and twigs in spring or early summer when fragrance is strongest. Cut with sharp pruners, taking no more than one-third of growth annually. Leaves can be dried for tea or medicinal preparations. Traditionally, resinous buds (with the glossy coating) are harvested in fall and used for salves.
