A reusable plant protector apparatus which can be anchored to the earth include A U5RU ,V:a flexible sheet having a top edge, a bottom edge, and two opposite side edges. The sheet defines a plurality of matching pairs of apertures which are offset from each of the side edges, so that the matching apertures in the opposite edges are aligned when the sheet is formed into a cylinder with a side edge overlap. The plant protector apparatus also includes a stake and a plurality of flexible ties extending through the apertures and around the stake for securing the overlapping side edges and the stake to each other. The ties are tightenable to tighten the stake against the overlapping edges thereby sealing the edges of the formed cylinder around the plant to be protected, thereby creating a sheltered climate of higher temperature and humidity around the plant. The plant protector apparatus may also be vented to adjust the temperature and humidity surrounding the plant. In one embodiment, the sheet is formed from a smooth inner layer and a corrugated outer layer, with the smooth layer extending beyond the outer layer at the top edge of the sheet. In another embodiment, ground engaging spikes are integrally formed in the flexible sheet at the bottom edge. A further embodiment is disclosed in which the sheet is extruded to define interlocking male and female fasteners along the opposite side edges to facilitate forming the sheet into a cylinder around the plant.

DETAILED DESCRIPTION One embodiment of the present invention is characterized by a resilient polymeric sheet having a top edge, a bottom edge, and two side edges.
The two side edges further comprise a plurality or matching pairs of apertures which are offset from the side edges.
The matching apertures are aligned such that an aperture on one side edge has a corresponding aperture on the other side edge when the sheet is formed into a cylinder.
The offset of the apertures from the side edges permits a small overlap of the edges.
The plant protector apparatus also includes a stake and a plurality of flexible ties which extend through the apertures and around the stake for securing the overlapping side edges and the stake to each other.
The ties are tightenable to press the stake against the overlapping edges thereby sealing the edges and forming a flexible cylinder around the plant to be protected.
In another aspect of the invention, the plant protector apparatus comprises a polymeric sheet having a substantially smooth inner ply affixed to an outer corrugated ply having grooves that extend longitudinally along the sheet.
A further feature of the present invention includes bendable flaps along the top edge of the smooth inner ply.
The flaps are defined by a plurality of longitudinal slits located on a portion of the smooth ply that extends beyond the top edge of the corrugated layer.
One object of the present invention is to provide a reusable plant protector apparatus which may be easily and quickly placed around a plant to be protected.
Another object of the present invention is to simplify installation of the plant protector by permitting attachment of the side edges and the stake together in one operation.
A further object of the present invention is to provide means for ventilating the plant protector, while another object of the invention is to provide a plant protector apparatus which is compact and economical to produce.
A further object is to provide a plant protector which may be easily installed around a tree having spreading branches above the trunk area
