Abstract
In areas susceptible to early-season flooding, cottonwood seedlings are thought to be superior to cuttings as planting material arid most tree planters prefer seedlings with root-collar diameters between 0.2 and 0.6 inch for these areas. Seedlings in this diameter range are generally of, acceptable height. The study reported here indicates that production of suitable seedlings will be near maximum with a bed density of about 16 seedlings per square foot. Results also show that in rows 38 inches apart, within-row spacing should be about eight seedlings per linear foot.
