Some Observations on the Use of the Transpiration Inhibitor "Plant Cote" on Lifted Tree Seedlings

For the past three years small quantities of seedlings of white fir, red fir, Douglas-fir, sugar pine, and Sierra redwood have been treated by dipping the tops and roots in a solution consisting of one part Plantcote and two parts of water. Since Plantcote forms the best films at temperatures above 70 degrees F. and since lifting operations generally are carried on during cool weather, the seedlings were subjected to warm air from the ventilator of an oil furnace until the shiny film was formed on the needles or foliage.
