Sexual: White ash samaras remain viable on the forest floor for 3 to 4
years . The samaras require cold stratification; in the laboratory
stratification at 41 to 14 degrees F (5 to -10 degrees C) for 2 to 3
months resulted in a mean germination of 54 percent. Germination is
epigeal and can occur on mineral soil, humus, or leaf litter, but the
substrate must be moist .
Vegetative: White ash resprouts from the root crown after logging or
fire. Sprouting ability decreases with age .
Silviculture: Young stands (5 to 10 years) respond to the addition of
nitrogen and thinning by increasing the number of stems per acre and
increasing in height growth by 1 to 2 feet (0.3-0.6 m) , whereas
older stands (35 to 85 years) do not exhibit increased growth from
fertilization or release .
White ash responds well to shelterwood cutting. Advanced regeneration
grows best with 60 percent of the overstory removed .
