Atlantic White-Cedar Propagation by Seed and Cuttings in New Jersey

Atlantic white-cedar— Chamaecyparis thyoides (L.) B.S.P.---propagation was tested using seeds and cuttings. Photoperiod played an important role in seed germination. Under 16-hour daylength, 31.9% of fresh seeds germinated, compared to 0.7% under 10-hour daylength. Cold stratification and gibberellin treatments could substitute for the photoperiod requirement. There was great variation in viability among seedlots from different cedar swamps. For seed propagation, 30-day stratification on sphagnum at 4 ºC is recommended. Optimal rooting (97.5%) was obtained on cuttings 6 to 7 cm (2.3 to 2.7 in) long taken from juvenile trees in November, dipped in powdered Hormodin #2, and stuck in a well-drained mix of Pro-Mix BX, peat moss, and sand under intermittent mist with bottom heat (24-26 ºC). Sturdy, well-developed root systems developed within 3 months. Tree Planters' Notes 45(3): 104-111; 1994.
