One-year-old seedlings usually are adequate, but they should be at least ¼-inch and preferably 3/8-inch in diameter 1 inch above the root collar. Seedling age and height are less important than stem diameter.
Bareroot seedlings are adequate for most planting sites. Plant them before bud-break. Containerized seedlings are much more expensive, but they can be planted later in the growing season and when soil is drier.
