Abstract
A plant growth media composition, articles made therefrom, and methods of making and using the same are described. The plant growth media composition includes a combination of one or more plant growth substrate materials and an additive such as cellulose fibers, clay, carrageenan, alginate, chitosan, or combinations thereof.
Claims13
A plant growth media composition comprising:
- a blend of plant growth substrate materials comprising 70% peat by weight of the blend of plant growth substrate materials, 20% coir by weight of the blend of plant growth substrate materials, and 10% perlite by weight of the blend of plant growth substrate materials;
- kappa-carrageenan present in an amount of about 2% w/w of plant growth substrate materials;
- and
- cellulose fibers consisting of cellulose present in an amount of about 2% w/w of plant growth substrate materials.

A method of making a stabilized growing media, the method comprising:
- mixing kappa-carrageenan and cellulose fibers consisting of cellulose, with a blend of plant growth substrate materials to form a fibrous mixture, wherein the blend of plant growth substrate materials comprises 70% peat by weight of the blend of plant growth substrate materials, 20% coir by weight of the blend of plant growth substrate materials, and 10% perlite by weight of the blend of plant growth substrate materials, wherein the kappa-carrageenan is present in an amount of about 2% w/w of plant growth substrate materials, and the cellulose fibers consisting of cellulose is present in an amount of about 2% w/w of plant growth substrate materials;
- configuring the fibrous mixture into a desired shape;
- and
- adding water to the fibrous mixture to activate binding of the fibrous mixture and produce a stabilized growing media of the desired shape.
