Abstract
Abstract An expandable pot for containing the roots of a plant is designed to expand primarily in response to the growth of the plant's roots. The sides of the pot are folded in an accordian-like manner which flexes outwardly to increase the volume of the pot in response to the growth of the roots therein. As the pot expands outwardly, additional soil is added into the pot in order to maintain the surface of the soil at a desired level. Formed beneath the expandable pot is a drain container and formed along the sides of the pot is a stop member for limiting the expansion of the pot to a predetermined volume.

Claim 3
Dependent Claim
96 words
A container for containing all of the roots of a plant, said container comprising: a circular bottom surface, sides formed from accordian-shaped material attached around the edge of said bottom surface at one end, said sides being open at the end opposing said attached end and beng responsive to the growth of said roots for flexing outwardly, said open end being of greater diameter upon expansion than said attached end, and means attached to said circular bottom surface cooperative with said sides for stopping the expansion of said pot at a predetermined volume in said pot.
Claim 4
Dependent Claim
96 words
A container for containing all of the roots of a plant, said container comprising: a circular bottom surface, sides formed from accordian-shaped material attached around the edge of said bottom surface at one end, said sides being open at the end opposing said attached end and beng responsive to the growth of said roots for flexing outwardly, said open end being of greater diameter upon expansion than said attached end, and means attached to said circular bottom surface cooperative with said sides for stopping the expansion of said pot at a predetermined volume in said pot.
Claim 5
Dependent Claim
13 words

Claim 7
Dependent Claim
135 words
A receptacle for containing all of the roots of a plant, said receptacle comprising: a bottom surface, flexible side walls attached at one end to said bottom surface, said flexible side walls being open at the end opposing said attached end and being responsive to the growth of said roots for flexing outwardly, said open end being of greater diameter upon expansion than said attached end, means cooperative with said flexible side walls for stopping the expansion of said container at a predetermined volume in said receptacle, said stopping means surrounding said sides and attached to said bottom surface, means attached to said bottom surface for collecting excess water in said receptacle, and said stopping means including means cooperative with said flexible side walls for slowing the rate of said expansion prior to said stopping.
Claim 8
Independent Claim
85 words
A method for growing plants, said method comprising the steps of: inserting a seed in a cylindrical container having expandable flexible sides attached to a bottom wall, said container containing soil and nutrients, repeatedly watering said seed in said container until said seed sprouts and grows into said plant, selectively expanding the flexible sides of said container to increase the volume of said container in response to the growth of said plant, and adding additional soil and nutrients to said container after each selective expansion.
