ABSTRACT:
A plant greenhouse frost protector and growth enhancer for use with seedlings or young plants. The protector is frusto-conically shaped and made of a light transparent, semi-transparent or translucent transmitting plastic material. The protector's base has a series of ground engaging serrations with adjacent spaced slots. Prior to forming tabs, base slots normally extend upwardly towards the protector's top edge. Normally serrations hold the protector to the ground by the serrations in low wind conditions. In high wind conditions, tabs are formed by folding the base's areas between the slots outwardly and upwardly. These formed tabs form ground engaging surfaces parallel to the ground. The top edge of the protector is covered by a convex raised center top surface with slots that permit access to the interior formed cavity to water or ventilate the enclosed seedlings or plant. Flange engaging anchoring objects are disclosed including right angled pegs, dirt piled against the flange's top surface and rocks placed on the flanges. These pegs may engage the flange tabs by either placing them in the slots between the tabs or by penetrating through the tabs into the underlying ground.
