Propagating Italian Cypress (Cupressus sempervirens) from Cuttings and Seed

Rooting Italian Cypress Cuttings

Italian cypress is best propagated from semi-hardwood cuttings taken in late winter (February) after dormancy is satisfied.

Cutting Protocol

1. Take 2–3 inch (5–8 cm) tip cuttings from the previous season’s growth.
2. Remove lower foliage; wound the base slightly.
3. Dip in rooting hormone.
4. Stick in perlite or coarse sand.
5. Cover with clear plastic; maintain high humidity.
6. Provide bright, indirect light; bottom heat (70°F / 21°C) speeds rooting.
7. Rooting may take 8+ weeks; check by gentle tug.

Dormancy Requirement

At least 6 weeks below 35°F (2°C) is needed to break dormancy. In Central Florida (Zone 9), cool January–February nights usually suffice.

Seed Propagation

If seeds are from non-hybrid trees, they can be cold-stratified (90 days in moist paper towel in fridge) and sown. Hybrid seeds will not come true.

Cuttings are preferred for uniformity; seed is for breeding or species-level propagation.
