Growing Notes

• Use fine, free-draining mix and keep the shallow surface evenly moist until emergence.
• Direct sow in reliable cool weather or transplant intact clumps once their roots hold together.
• Harden plants over 5–7 days and trim after a flower flush to keep the carpet compact.
• Allow for self-sowing where Snow Cloth is used as living mulch.
