Propagating Conifers from Seed and Cuttings

Two Main Methods for Conifer Propagation

Conifers can be grown from seed (found in cones) or from cuttings. Both require patience and specific conditions.

Seed Propagation

1. Collect mature cones in autumn; allow them to open and release seeds.
2. Cold stratification: Most conifer seeds need 90+ days at 40°F (4°C) or below. Place seeds in a damp paper towel inside a sealed bag in the refrigerator, or sow in pots and leave outdoors for winter.
3. Sow after stratification: Plant 1 inch deep in moist, well‑draining mix. Keep at 65–70°F (18–21°C).
4. Germination: Can take several weeks to months; some species require multiple warm/cold cycles.

Cutting Propagation

• Take semi‑hardwood cuttings in late summer/early autumn.
• Use a rooting hormone (e.g., IBA powder).
• Stick in a sterile, well‑draining medium (perlite/peat).
• Maintain high humidity (mist or plastic cover) and bottom heat (70°F).
• Rooting may take 8–16 weeks.
