Planting & Care

Keep evenly moist until germination, which typically occurs in 14-30 days. Thin seedlings to stand 12-18 inches apart. Water regularly during dry spells, but avoid overwatering. Mulch around plants to retain moisture and suppress weeds. Deadhead spent flowers to encourage continued bloom and prevent self-seeding if desired.
