Neat little idea for producing as many pots as you want, quickly, easily and cheaply.   Recycling too.

• Take a tabloid sized sheet of newspaper, and fold it in half lengthways.
• Roll this around a soup can (or a beer can, syrup tin, jam jar, whatever!) leaving a good rim overhanging the bottom.
• Crimp and fold the overhang over the bottom, and press firmly on a hard surface to "set" the folds.   I'd stick a little sellotape to keep the roll shape, and on the bottom.
• Fill with seed compost, place in a seed tray so that the pots support each other, and pop in your seeds.
• As long as you water from the top (into the compost), and not from the bottom (filling the tray!) your pots should hold well until the plants are ready for transplanting.
• Simply pop the whole pot into a hole in your bed - transplanting with no root disturbance!   Snip the sellotape holding the bottom (and trim excess newspaper?) so that roots can get through easily into the soil.
• You might consider leaving a one inch rim of newspaper pot ABOVE the soil level, as a barrier to ground pests?   Otherwise, tear off the excess at the top.
• And as your sweetcorn grows off, the pot rots away!

Adapt the instructions to fit the size of pot you want - a pot made on a smaller "mould" could be made with a single 4 or 5 inch wide strip of newspaper, for example.
