Start with a simple, low-maintenance approach to growing Oyster Plant.
A small pot or garden bed, seeds or young plants.
Plant in spring after the last frost or in fall before the first freeze.
Use well-draining soil with a pH between 6.0 and 7.5, ensuring good drainage.
Direct sow seeds outdoors in early spring or start indoors 4-6 weeks before the last frost.
Water sparingly to keep soil moist but not soggy, and place in a sunny spot.
Provide full sun to partial shade, water when dry, and mulch around the base for moisture retention.
Prune after flowering to encourage new growth and maintain shape; harvest leaves and flowers as needed.
