Soil: Thrives in well-drained, slightly acidic to neutral soil (pH 6.0-7.0); enrich with compost before planting.

Watering: Requires regular watering, especially during dry periods; keep soil consistently moist but not waterlogged.

Fertilizing: Apply a balanced, slow-release fertilizer in early spring and again in mid-summer for vigorous growth.

Pruning and Maintenance: Deadheading will improve the plant’s appearance. Prune in late winter or early spring before new growth appears to remove dead stems and encourage bushier growth.

Mulching: Apply a 2-3 inch (5-7 cm) layer of mulch around the base to retain moisture, control weeds, and protect roots in winter.

Propagation: Propagate through stem cuttings or division; best done in spring or early summer.
