ABSTRACT:
A normally horizontally arranged sack-like bag formed of a capillary type, wicking sheet material which is filled with a plant growth material such as peat moss, soil compositions and the like. At least one loose flap, which is part of a lower surface forming portion of the bag, extends downwardly from one edge of the bag for immersion in a liquid, such as water, water-fertilizer mixtures and the like. The liquid is continuously flowed by capillary action up the flap and along at least the lower surface of the bag for continuous dispersion into the filler material for feeding liquid to the roots of plants which are grown through the upper surface of the bag. Preferably, the sheet material is pre-selected to provide a capillary flow which roughly corresponds to the expected loss of liquid to the plants and the atmosphere to thereby create a generally equilibrium flow of liquid to and from the bag.
