The bag (20), designed to hold a plant cultivated in open ground, e.g. a nursery, and filled with soil from the ground as it is planted, is made from two layers of non-woven jute fibres with a density of 300 to 500 g/sq m, separated by a thin layer of plastic film with the three layers sewn together. The bag, which can have an additional inner layer of thin plastic film, is made from an initial rectangle of material, shaped and sewn to make the required shape. |
