ABSTRACT:
A readily adjustable, moisture retainable, air transferable soil covering, integral with fertilizer and, if desired, fungicide is provided that may be used with indoor plants. The soil covering is made up of a biodegradable cellulose paper and film covering having thereon water soluble beads of fertilizer or fungicide. The covering has been perforated in a series of concentric circles together with at least one radial perforation so that the unit may be torn radially to the proper size for the pot, may have an opening in the center for the stem of the plant, and may be torn radially to allow insertion of the stem.
The same type covering may also be utilized in rolls for gardens and can be perforated in regular design for regular spacing of plants.
The perforations serve the additional purpose of providing for water permeability while the film covering prevents moisture evaporation and permits air to reach the soil,
As the plant is watered, a certain portion of the fertilizer is dissolved from the undersurface of the discs and enters the soil to feed the plant. Water is also absorbed by the paper and released, with additional fertilizer over a period of time.
