Based on experiments with Larix laricina (Du Roi) K. Koch, environments and treatments are described that achieved good rooting, overwintering and subsequent development. Cuttings rooted best if taken from seedlings 3-6 years old during the last week of July, when lignification begins at the base of newly formed shoots. Overwintering in sealed, cold greenhouses or open shade-halls is possible during the first winter if the rooted cuttings are hardened off for at least 4 weeks before mid-November. Clonal selection at the age of 6 years for stem straightness appears to be possible. Key words: Vegetative propagation, age, season, rooting chamber, overwintering, stem staightness.
