I grow mine in a 1m square bed they grow as much as you let them. the tubers can grow huge depending on how long they have in the ground at the right temperatures. My last lot seemed to be fairly small but i think i dug them up to soon, 20 cm long and 5cm diameter.
You can also grow in a very small plot - they grow suprisingly well suspended in a glass of water on the window sill. Use a few toothpicks to support on surface of water
You need an area that will allow the runners that will grow from the cut pieces of tubers to run over a large area,
Mine grow over approx 6x6 metres and still want to spread.
Tubers can grow up to at least around 2 kilos or more.
