[QUOTE="Cadence, post: 8109166, member: 6701124"] I'm wondering what happens to the ground temperatures in the second year. Apparently that's what would kill them: [URL="https://extension.umn.edu/planting-and-growing-guides/protecting-trees-and-shrubs-winter"]Protecting trees and shrubs in winter[/URL] "Roots of most trees and shrubs that grow in Minnesota die at temperatures at or below 0 and up to 10 degrees. These plants survive in Minnesota because soil temperatures normally are much higher than air temperatures and because soil cools down much more slowly than air temperature. Many factors influence soil temperature. [LIST] [*]Moist soil holds more heat than dry soil, so frost penetration will be deeper and soil temperatures colder for sandy or dry soils. [*]Snow cover and mulch act as insulators and keep soil temperatures higher. [*]With newly planted trees, cracks in the planting hole allow cold air to penetrate into the root zone, reducing fall root growth or killing newly formed roots." [/LIST] It also knows that having less sun would actually be a help for them surviving if the cold doesn't go away: "Bright sunny days during the winter warms plant tissue, which in turn initiates cellular activity. Then, when the sun sets or goes behind clouds, foliage temperature can drop, injuring or killing the foliage. Bright, cold winter days destroy chlorophyll in the foliage. The chlorophyll does not re-synthesize when temperatures are below 28 degrees. This results in a bleaching of the foliage." [/QUOTE]
