Effect of Polyethylene and Regular Packing Methods on Ponderosa Pine and Douglas-Fir Seedlings Stored Over Winter

Shipping nursery stock without moss or other packing material on the roots permits considerable economy in packing and shipping charges. That it is practical under certain conditions has been shown by Professor John P. Mahlstede's1 work with ornamental nursery stock shipped completely enclosed in polyethylene bags, and by Duffield and Eide2 a who successfully packaged Douglas-fir seedlings in such bags with granulated wet peat for 6 weeks or so. We tested its feasibility at the Mt. Shasta Nursery in 1956-57 and in 195859 by contrasting our regular packing method with the method of packaging trees in polyethylene bags without packing material on the roots.
