Chapter 16: Plug + 1 Seedling Production
The recently developed plug+1 seedling begins life as a typical plug in a containerized nursery. At the end of its first year, it is transplanted to a bareroot nursery, where it continues to grow for another year before outplanting. This new stock type, with bushy top and moplike, fibrous root mass, has had good survival and height growth on typical Northwest transplant sites. It has also shown , on these sites, a comparable or better total cost:benefit ratio than any other seedling type currently in use.
