DEFLASKING: For Beginners
Acclimatize the flask for a few days in the immediate growing area preferably shaded and with an even temperature, not less than 60 dF (15 dC) for cool growing plants, avoid extremes, preferably adapt a small hotbed; remove plants very carefully and breaking the flask may be unavoidable; soak seedlings for 10 minutes in a fungicide such as Benlate, arrange them by size and save all for planting in green sphagnum moss which had previously been washed, cleaned, wrung dry, chopped to 1/2 inch lengths; place some leafy dead fern frond in the bottom of the seedling tray before filling it with the moss, for beneficial fungus; plant in rows against strips of moss.

DEFLASKING: Professional Procedures
Use fine fir bark, use lukewarm water, plant firmly but not deeply, avoid strong light, not over 1500 foot-candles and a night temperature of not below 65 dF with humidity not below 75% and provide good air circulation; if plastic bags are used to cover them, open each day for fresh air and remove the bags when the seedlings are established; never let the bark dry out so mist at least oace a day; in four to six weeks root action should begin and a nitrogen fertilizer at 1/4 strength should be applied; overdoses of fungicide are damaging.
