Establishment
Year 1Young shrub developing root system and baseline foliage structure with leathery green leaves
Water regularly for first season to establish roots. Protect from harsh winds. Avoid transplanting; Garrya prefers to settle in one location.
Vegetative Growth
Years 2-3Shrub develops dense, evergreen foliage with thick leathery leaves arranged opposite each other
Minimal pruning needed; maintains natural form well. Light shaping after flowering if needed. Feed sparingly—excessive nutrients reduce hardiness and flowering.
Pre-flowering
AutumnBuds form along stems in late summer and autumn, visible as small protrusions
Do not fertilize heavily in late summer. Ensure good light exposure. Protect from hard frosts which may damage tender catkins.
Flowering & Catkin Display
December-February (peak: January-February)Dramatic wine-burgundy catkins (male flowers) emerge 4-8 inches long, hanging in clusters from stems
This is the main ornamental feature. Catkins last 8-12 weeks. Avoid pruning during this period. Enjoy the winter interest and structure.
Post-flowering & Summer Rest
March-NovemberCatkins fade and drop; shrub returns to steady evergreen foliage without significant new growth
Light pruning or shaping acceptable post-flowering. Maintain good drainage. Reduce watering in summer if rainfall is adequate.
