Helping meet new environmental regulations
Evolving environmental regulations for fumigating to control pests and diseases will require many US forest nurseries to increase buffer zones around summer-fallow barerootShort form: BR

fields. Growing space at some nurseries, therefore, will be reduced up to 50%, increasing production costs significantly.
Lower cost. Better survival.
PRT, meanwhile, has long recognized the benefits of container-grown seedlings. They require no fumigation, establish faster and reduce seed cost, as the growing techniques improve both seed utilization and germination rates. Seedling losses from harvest damage and over-wintering outdoors are also reduced, resulting in more consistent seedling production.
Anticipating the full impact of new environmental regulations, we developed a new line of large container seedlingsContainer seedlings are grown as “plugs” in containers. The important aspect is that their roots are not damaged during the harvesting process and, as a result, they generally perform better than bareroot products. See Plug Seedlings. in 2009. We then launched a Bareroot Replacement Program at our PRT Oregon nursery to enable customers to test our container-grown product. It didn’t take long for companies to recognize the advantages of large plug seedlingsMany foresters and nurseries refer to container-grown seedlings as “plug” seedlings. These seedlings are grown in cells in blocks or trays made from expanded polystyrene or polythene. PRT seedlings are grown in expanded polystyrene (dense white Styrofoam). The growing medium contains a high component of peat moss in most cases. By the time of harvesting, the roots bind the medium into a cohesive “plug” that keeps the shape of the cell..
Same size. More flexibility.
Today, we provide two-year-old container-grown Douglas-fir seedlings to customers in Oregon, Eastern Washington and Idaho. Western Red Cedar and Western Hemlock will be added soon.
Our seedlings are similar in size to bareroot products, but they take less time to produce and grow vigorously. They also give customers greater flexibility with their reforestation activities.
