In the nursery, unstratified seeds may be sown in the fall or stratified seeds may be sown in late winter or spring. Spring sowing appears to be best in areas where depredation by rodents is a serious problem. The sown seeds should be covered with about 6 mm (0.25 in) of soil and mulch should be kept on the beds until all danger from frost is past. The emerged seedlings need half shade during much of their first summer. Normally, plantings are established with 1-0 seedlings (23).
The possibilities for natural regeneration of sweetbay are greatest in natural openings or in clearcut swamps. In such openings, survival of the germinated seedlings is high unless they are inundated for an extended period. First-year growth usually averages between 30 and 60 cm (12 to 24 in). First-year seedlings are fairly tolerant of shade and competing vegetation (19).
