Patent attributes
A portable apparatus for protecting a specimen tree from substantial cold weather damage. The apparatus includes a hollow housing preferably having a generally flattened configuration and being adapted in horizontal size for positioning beneath, and being substantially smaller than, a canopy perimeter width of the tree. An air movement source is mounted within, and arranged to draw air into the housing preferably through apertures in a lower panel thereof. Air discharge openings are formed around an edge perimeter of said housing for discharging air generally laterally or radially outwardly therefrom produced by the air movement source. A ground support is connectable to and for holding the housing above the ground and beneath a canopy of the tree so that discharging air protectively intermingles with, and produces airflow around the foliage of the tree. An air heat source is also provided which enhances foliage protection.
