Glad your Internet is back up and running, Carolyn!

Kaolin sprays, like Surround, also have potential in preventing ice crystal damage and are acceptable to a wide variety of growers.

"In his (ARS' Michael E. Wisniewski, a plant physiologist at Kearneysville) tests in environmental chambers, kaolin-treated tomato and bean plants have withstood temperatures as low as 21°F (-6°C). They normally die when the thermometer drops to 28°F (-2°C)."
