Abstract
Abstract A cultivation ball is formed from at least one envelope, which is sealed or substantially sealed, containing the cultivation substrate; the plant is disposed in the ball, being separated from the substrate by at least one wall of the envelope or envelopes, and each envelope is made from a material through which the roots of the plant can pass once the ball has been set to grow. The substrate-containing envelope can be produced industrially at high rates of production, and is easily applied to the plant.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
182 words
A plant cultivation ball comprising at least one envelope in the form of a flattened elongated tube having an inner wall and an outer wall, a powdery cultivation substrate within the tube, means closing each end of the tube to prevent escape of the cultivation substrate from the tube, said tube being wound around the plant and around itself to form a ball of at least one convolution within which the plant is separated from said substrate by at least one wall of said envelope, said inner wall of said tube comprising a first sheet, and said outer wall of said tube comprising a second sheet, said sheets being joined together along their longitudinal edges, said sheets forming said walls of said envelope each comprising a material through which the roots of the plant can pass once the ball has been set to grow and said tube being devoid of any attached root impermeable covering so that the roots of a plant within the ball can pass freely through the ball into the medium in which the plant is set to grow.
Claim 2
Dependent Claim
182 words
A plant cultivation ball comprising at least one envelope in the form of a flattened elongated tube having an inner wall and an outer wall, a powdery cultivation substrate within the tube, means closing each end of the tube to prevent escape of the cultivation substrate from the tube, said tube being wound around the plant and around itself to form a ball of at least one convolution within which the plant is separated from said substrate by at least one wall of said envelope, said inner wall of said tube comprising a first sheet, and said outer wall of said tube comprising a second sheet, said sheets being joined together along their longitudinal edges, said sheets forming said walls of said envelope each comprising a material through which the roots of the plant can pass once the ball has been set to grow and said tube being devoid of any attached root impermeable covering so that the roots of a plant within the ball can pass freely through the ball into the medium in which the plant is set to grow.
Claim 3
Dependent Claim
32 words
A cultivation ball according to claim 1 wherein said envelope is held in position by fixing means securing an outer end of the tube to an adjacent outer surface of the tube.
Claim 4
Dependent Claim
23 words
A cultivation ball according to claim 1, wherein the tube comprises a continuous tube with a plurality of closed compartments containing cultivation substrate.
Claim 5
Dependent Claim
23 words
A cultivation ball according to claim 1, wherein said tube is rolled around a ball which has already been cultivated in the nursery.
Claim 6
Dependent Claim
112 words
A process of forming a cultivation ball comprising the steps of making a flattened tube of great length by joining along their longitudinal edges, two sheets of material through which plant roots can pass, said tube is cut into sections and is filled with a dry powdery cultivation substrate, each end of a section is closed, and the resultant closed element filled with substrate is then wound up about itself with at least one convolution around a plant disposed in the center to form a cultivation ball through and beyond which the plant roots can grow and pass, and is fastened to the envelope at the free end of the woundup element.
Claim 7
Dependent Claim
112 words
A process of forming a cultivation ball comprising the steps of making a flattened tube of great length by joining along their longitudinal edges, two sheets of material through which plant roots can pass, said tube is cut into sections and is filled with a dry powdery cultivation substrate, each end of a section is closed, and the resultant closed element filled with substrate is then wound up about itself with at least one convolution around a plant disposed in the center to form a cultivation ball through and beyond which the plant roots can grow and pass, and is fastened to the envelope at the free end of the woundup element.
Claim 8
Dependent Claim
32 words
Process according to claim 5, in which the flattened tube is formed from a material selected from among the group consisting of asbestos, glass wool, rock wool, and synthetic or natural fibers.
