Difficulty Moderate Rated by us, not by the source.

Start around September 17, 2027 for a May 3 last frost. Too late for spring 2027 — that needed starting on September 16, 2026.

  1. Cold moist stratification

    Duration: 90 daysTemperature: 40°F 4°C

    20 germinated in this phase.

  2. Warm moist stratification

    Duration: 90 daysTemperature: 70°F 21°C

about 6 months from start to sowing. Germination time not stated; 21 days assumed.

45% germination.

Abies (Pinaceae). Grateful acknowledgement is made to Schumacher Seed Company of MA for a gift of fifteen species of this genus. All fifteen germ. at 70D albeit somewhat slowly with germination taking place in 5-10 weeks. Some gave slightly greater percent germination with light or in a 40-70D pattern, but, GA-3, OS, or OT had no significant effects. Some germ. at 40. A significant number of the seeds rotted indicating ,that they were dead.'but there was no simple way of detecting such seeds from outward appearance nor of separating them. The seeds of all .fifteen species were largely viable and producing healthy seedlings.
