Possibilities in the Rooting of Quercus glauca
H. William Barnes
Quercus glauca (syn. Q. myrsinifolia) is an evergreen oak from Japan, China, and Laos that is hardy to Philadelphia, Pennsylvania. It has leathery dark green leaves that are long and narrow, somewhat resembling a peach or willow leaf. The foliage is clean and the branching is well spaced creating an attractive ornamental tree.
There are several accessions at the Morris Arboretum of the University of Pennsylvania in Philadelphia, Pennsylvania, and I took on a study to understand the rooting potential of this species. Dirr (1998) says in passing that Q. glauca can be rooted with K-IBA with a 1% dip with cuttings taken in June, but he does not go into specifics.
