Indoor Planting – Start White Sea Holly seeds indoors 8-12 weeks before your last expected frost date. For better germination rates, consider cold stratification: place seeds in a moist paper towel, seal in a plastic bag or container, and refrigerate for 2-4 weeks before planting.

Direct Sowing – Seeds can also be direct-sown in early spring or fall.

Planting Depth & Light Requirements – Press seeds onto the soil surface without covering them; light is essential for germination. Keep the soil consistently moist until germination, which can occur within 5-90 days. Germination may be sporadic, with seedlings emerging at varying times.

Spacing Requirements – Once seedlings are established, transplant them outdoors in a sunny location after the last frost. Space plants 18-24 inches (45-60 cm) apart for optimal growth.
