Improved methods and devices for cultivating a young plant comprise temporary insertion into the soil close to and around said plant of a substantially impervious material so as to form a small enclosure assuring retention of most nutrients near said plant. Small perforations in said material permit drainage of excess water from said enclosure. Identations along lines joining said perforations facilitate breaking, tearing or cutting of the material to an appropriate size. A sharp leading edge may be provided along the perforations and indentations to facilitate insertion of the material in the soil around the plant. The material may be in form of an assortment of tubes or of a sheet adaptable to being bent into a cylindrical or conical configuration.
