Planting & Care Guide
Ideal Location
Select a sheltered site with morning sun and afternoon shade or full shade. Provide a sturdy support such as a wall, arbor, or fence. Enrich soil with organic compost prior to planting to encourage strong root development.
Watering
Keep soil consistently moist but never waterlogged. During establishment, water deeply once a week. Mature plants tolerate short dry spells but perform best with regular moisture, especially during hot, dry periods.
Pruning & Maintenance
Prune in late winter or early spring before new growth appears. Remove dead or weak wood, thin older stems to the base to encourage fresh shoots, and lightly trim to maintain shape. Minimal feeding with a balanced, slow-release fertilizer in spring enhances vigor.
