(EN) A plant pot comprising a hardened matrix of fibres (10) forming the wall and exterior surface of the pot and a low density matrix of similar fibres (13) within the pot. A method of forming a plant pot as described by preparing a slurry of fibres of a fibrous material compatible with plant growth, introducing a first portion of the slurry into a perforated mould while the mould is subject to a vacuum externally on all sides but not the top or bottom, allowing a film of fibres to form on the inside of all sides of the mould to constitute the external shell of the plant pot and introducing a further portion of the slurry and then additionally applying a vacuum from top and bottom of the mould so as to form a low density matrix within the plant pot.
