ABSTRACT:
A plant protecting and growth enhancing device is disclosed for use in providing an environment immediately surrounding a plant to protect the plant from atmospheric changes during its early life of growing. The plant protector is a rigid, conical, transparent device that is adapted to contain a fluid that may absorb thermal energy from an outside source and may release that absorbed thermal energy at another time. The device is adapted to be placed over a seedling plant as the plant is planted and is capable of protecting the plant from frost or other possible detremental conditions until the plant has a chance to become established. The fluid within the device may be drained onto the plant when the device is no longer needed.
