Planting & Care

Sow seeds indoors or in a protected area after the last frost risk has passed. Lightly scarify or soak seeds before sowing to help soften the seed coat, then press them into a moist, well-drained seed-starting mix and cover lightly. Keep the medium consistently moist but not waterlogged, and provide warmth and bright light for germination.

Once seedlings are sturdy, transplant them into individual pots and harden them off gradually before moving outdoors. Choose a sunny site with well-drained soil, water regularly during the first season, and mulch to conserve moisture. Established shrubs are relatively low-maintenance; prune lightly as needed to shape plants and remove spent growth.
