Italian Cypress Seed Germination: Stratification and Sowing Protocol

Cone collected spring from Italian cypress (not ground). Seeds released. Owner asks germination method and success rate.

Realistic Expectations

25–50% germination typical. Not all seeds viable.

Protocol

1. Remove wings: rub seeds between hands.
2. Cold stratify: wet paper towel, fold seeds inside, seal in bag, refrigerate 1 month.
3. Sow: barely cover in potting soil. 68°F (20°C). Germination 1–2 months.
4. Prevent damping off: careful watering, good ventilation.
5. Prick out to individual pots when handleable.
6. Grow in greenhouse/cold frame first winter.
7. Plant out late spring/early summer after last frost.

Patience—conifer seedlings grow slowly initially.
