Survival and growth of two oak species, live oak (Quercus virginiana) and Nuttall oak (Quercus texana), and three planting stocks: 1-0 bareroot, conventional containerized, and Root Production Method (RPM™) seedlings were compared. Conventional containerized live oak and bareroot Nuttall oak seedlings exhibited greatest survival. RPM™ seedlings exhibited the lowest survival in both species. Conventional containerized seedlings exhibited greater groundline diameter (GLD) growth and twice as much height growth as bareroot seedlings during the first year. During the second year, conventional containerized seedlings exhibited greater GLD growth than bareroot seedlings in live oak, but in Nuttall oak, bareroot seedlings exhibited greater GLD growth. RPM™ seedlings exhibited similar GLD growth compared to bareroot seedlings during both years but the least height growth of all planting stocks, regardless of species. Height growth of bareroot and conventional containerized seedlings was similar after two years.
