Protocol

1. Sow in cold frame late winter (barely cover).
2. When handleable, prick out to individual pots.
3. Grow in greenhouse first winter.
4. Plant out late spring/early summer after last frost.

Alternative (Large Scale)

Outdoor seedbed mid-spring. Grow 2 years. Plant out late autumn/early spring.

Patience—conifer seedlings are slow.
