Anti-Freeze For Your Plants
Botanists Develop 'Antifreeze' Spray for Plants
November 1, 2008 — Botanists developed a spray that, when misted over a plant, will help it endure temperatures 2.2 to 9.4 degrees Fahrenheit colder than it would without the spray, depending upon the species. The spray, called Freeze-Pruf, reduces the freezing point of water inside the tissues of the plant by means of a mixture that combines five ingredients in a water-based spray formula. One spray works for four to six weeks, lowering the temperature at which damage first becomes noticeable as well as the temperature that would normally kill the plant.
