Seeds or small plants, a trowel, and a watering can.
Plant in spring after the last frost or in fall before the first freeze.
Choose a location with well-draining soil that is light (sandy), medium, or heavy (clay). Ensure it gets full sun to partial shade.
Direct sow seeds in the ground or start them indoors 4-6 weeks before planting outside. Transplant young plants into a moist, well-draining soil.
Water regularly to keep the soil consistently moist but not waterlogged. Monitor for any signs of stress or pests.
Provide regular watering during dry spells and mulch around the base to retain moisture. Prune dead foliage in early spring to encourage new growth.
Prune spent flowers to promote more blooms and maintain a tidy appearance.
Overwatering, planting in poorly drained soil, neglecting to prune dead foliage, and not providing enough sunlight.
