Abstract
Abstract The root-ball wrapping is constituted of a material formed by a non-woven material, and has a shape and size determined so that, when the root-ball rests on the central zone of the wrapping, the peripheral zone of said wrapping can be turned up around a rootball and against the latter so as to mate the shape of the rootball and to surround the stem-base of the plant. The wrapping is fixed by means of a flexible tie, binding said peripheral zone at the level of the stem-base of the plant.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
85 words
A method for wrapping the root-ball of a plant comprising placing a non-woven wrapping of a material comprising a plurality of randomly distributed fibers and having a substantially circular shape around the root-ball so that the wrapping conforms to the shape of the root-ball and the peripheral edges of the wrapping surround the stem-base of the plant and fixing the wrapping in place using a flexible tie to bind the wrapping together in an area adjacent the peripheral edges of the stembase of the plant.
Claim 2
Independent Claim
85 words
A method for wrapping the root-ball of a plant comprising placing a non-woven wrapping of a material comprising a plurality of randomly distributed fibers and having a substantially circular shape around the root-ball so that the wrapping conforms to the shape of the root-ball and the peripheral edges of the wrapping surround the stem-base of the plant and fixing the wrapping in place using a flexible tie to bind the wrapping together in an area adjacent the peripheral edges of the stembase of the plant.
Claim 3
Dependent Claim
34 words
A method for wrapping the root-ball of a plant as claimed in claim 1 wherein said wrapping is shaped into the form of an open-ended frusto-conic container prior to being placed around the root-ball.
Claim 4
Dependent Claim
36 words
A method for wrapping the root-ball of a plant as claimed in claim 2 wherein the wrapping shaped into the form of an open-ended frusto-conic container is locally reinforced prior to being placed around the root-ball.
