DescriptionRepeated growing-season frosts during late April and early May 1985 caused extensive damage to red alder (Alnus rubra Bong.) seedlings in a newly planted research trial in western Washington. About two-thirds of the seedlings were severely damaged (entire stem damaged or necrotic). Such damage varied by family, from 50 percent of seedlings in the least affected family to nearly 90 percent of seedlings in the most sensitive family. Seedlings planted in plots fertilized with triple superphosphate suffered greater damage than those in unfertilized plots.
