Abstract
Abstract A liner for plant pots covers substantially the entire interior surface of the pot and has upwardly extending finger grips which project through the top of the soil, permitting the liner to be gripped and drawn upwardly, raising the root and soil mass of a plant free of the surrounding pot, the flexible sheet member which comprises the liner being made in two or more distinct segments joined at the bottom such that they can easily be parted from the soil mass permitting the repotting of the mass, ordinarily into a larger pot or container.
