Cottonwood Seedings at the Mason State Tree Nursery
Our cottonwood beds are 42 inches wide inside, boxed in with 1 x 6 native lumber. Two rows of 1 x 6 bedboards are also used to divide the bed lengthwise into 14-inch strips. These interior boards serve as baffles to keep the cotton from drifting to the sides of the bed. The 1 x 6 frame is covered with standard snow fence. The cottonwood catkins are hung from the snow fence wires. We hang a catkin in each space between laths in each of the three strips. This provides a row of catkins over each strip with the catkins about 3 inches apart in each row. Six-inch spacing would probably be sufficient with good catkins. The pods can also be stripped off the stems and scattered on the dry bed surface to open. When the humidity is low ripe pods open rapidly.
