Rooting Spruce Cuttings: Difficult but Possible

Spruce (Picea) cuttings root slowly and need specific conditions.

Protocol

1. Take 6-inch green cuttings in late spring/early summer.
2. Dip in rooting hormone.
3. Stick in wet sand; keep medium moist and warm (~80°F).
4. Seal in clear bag; mist twice daily.
5. Rooting takes several months; check by gentle probing.

High humidity and bottom heat are critical. Success rates are low.
