Class. Northern Gardening. Improving Cold Hardiness in Cold Climates

90 min audio class and 7 pages of notes covering game changing information about naturally improving a plants cold tolerance with minerals, amendments and soil microbiology. Change the game in short growing seasons by naturally unlocking a plants ability to produce its own "anti-freeze", improving a plants tolerance to cold snaps, frost, freezing and temperature swings. By improving a plants natural cold tolerance, this can greatly extend a growing season. This class focus is on northern cold climate clay based soils, and how to unlock the soils capability with soil amendment options and methods to greatly improve a plants tolerance in harsh climates.
