ABSTRACT:
An insulating device or insulator for trunks of trees or plants is described that provides protection and thermal insulation against damaging cold during their tender years. This device is adjusted for fit about the trunk by the trunk itself as it increases in girth, thus providing effectiveness for several years without attention. The insulating device is weather resistant, protecting the young trunk from both wind damage and the effects of water from rain or irrigation. The device also protects the trunk against bark chewing rodents and prevents sprouting along the lower trunk. A preferred embodiment of the device includes liquid receiving pockets that act as "heat sinks" to protect the trunk from below freezing temperatures.
