Bonsai Soil Test 2: Freeze-Thaw Cycles!!

This video is the second in a series of tests to examine various components often used in bonsai soil mixes. These videos are meant to inform you of what's available so that you may make your own choices. Soil mixes are determined by tree species, climate, region of the world, and personal preference. No two persons' mixes are alike. I hope this information is helpful to you. Enjoy!
