ABSTRACT:
A root control bag of the invention is ued to contain the roots of growing plant stock during in-ground cultivation prior to later excavation and transplantation after the plant has reached a desired stage of maturation. The root control bag includes a wall manufactured from a non-woven fabric formed of a multiplicity of substantially continuous, randomly aligned, polymeric fibres, needle puncture bonded together. A standard probe penetration test is defined in the specification and the physical characteristics of the fabric must fall within certain limits as defined with respect to the standard test. The test basically comprises pressing a standard probe through the fabric and recording the load on the probe. For each test an initial puncture reading is taken, as well as a final penetration reading.
