Abstract: A forming apparatus, particularly adapted for use by home gardeners, enables the erection of a square sheet of paper, which may be used newsprint paper, into a soil-decomposable pot suitable for raising and transplanting seedlings. Selected portions of the paper blank are adhesively treated and folded over a combined truncated pryamidal core and an associated drying stand, the latter being removable for upright positioning to dry and harden the mounted pot.
