Starting from Seed

When to Sow:

• Indoors: Start seeds indoors 6–8 weeks before last spring frost. Keep seedlings in warm conditions (70–75°F) with bright light.
• Outdoors Direct Sow: Direct sow in spring after frost danger has passed. Scatter seeds on soil surface without covering (light-dependent germination).
• Warm Soil Beneficial: Warm soil (65–75°F) speeds germination, though Alyssum is quite flexible with temperature ranges.
• Light Exposure Essential: Seeds require light for germination. Do not cover seeds with soil. Press lightly into soil surface.

Sowing Method:

• Press seeds lightly onto prepared soil surface or seed-starting mix. Seeds are very small and require light exposure for germination.
• Germination: Keep soil consistently moist but not waterlogged. Carpet of Snow Alyssum seeds typically germinate within 5–10 days under proper light conditions.
• Light Critical: Provide bright indirect light from sowing onward. Light exposure is essential for successful germination and healthy seedling development.

Seedling Care: Once seedlings develop true leaves, provide bright light and warm temperatures. Seedlings are easy to grow and very forgiving. Thin seedlings to proper spacing (6–9 inches apart) when 2–3 inches tall. Transplant outdoors after frost danger passes into full-sun to partial-shade locations with well-draining soil.
