Wind Shake Plus Wind Chill Equals Trouble

        "The freezing point of stems and large roots is approximately 28 or 29 F. We have found that water will flow through stems that are held at 29 to 30 F as long as the stems do not freeze. If the plant is not shaken, it is possible to lower the stem temperature to about 25 F without freezing, and water continues to move up the stem. If the plant is shaken by wind as the temperature falls, freezing takes place at near 28 to 29 F." John R. Havis, "Winter Desiccation Injury of Rhododendrons". The complete and interesting article is in the January 1969 issue of the Bulletin.
