Please Explain . . . What's a plug seedling? When someone refers to a plug seedling, they are referring to a tree grown in a small container (2-5 cubic inches) usually for one growing season, inside a greenhouse. What's bareroot? This stock has been grown in an outdoor nursery and packed without soil on the roots. This stock can be either 1, 2 or 3 years old. Seedlings are generally classified by age in the seed bed and age in the transplant bed. What's a transplant? Transplants are trees that were grown for 1 or 2 years in a seed bed and then transplanted at a wider spacing into a transplant bed. This would include a Plug + 1 (grown first year in a greenhouse), 1 + 1 or a 2 + 1. Transplants generally have a root system made up of more fine roots and will typically exhibit better first year growth and survival than a non-transplant.

If you're looking for a tree to plant in an area that doesn't get much sun, try western hemlock or grand fir. Cedar would be another option.    Wet areas? For wet areas that may have some standing water or poor drain-age, try grand fir or lodgepole pine. Editor's Note: This information is furnished as a courtesy from Weyerhaeuser Co.
