Seeds, small pots or garden space, good quality soil.
Plant in spring after the last frost or start seeds indoors about 4 weeks before planting outdoors.
Use well-draining soil with a pH between 6.5 and 7. Ensure containers are at least 15 cm deep.
Direct sow seeds 0.5 cm deep, spacing them about 15 cm apart. For indoor starts, use small pots with drainage holes.
Keep soil consistently moist and provide partial shade to prevent seedlings from drying out.
Water regularly, especially during dry spells, and mulch around plants to retain moisture. Pinch back flowers for bushier growth.
Prune spent blooms to encourage more flowering and maintain plant shape.
Overwatering, planting in heavy soil, neglecting to pinch back blooms.
