Here is how they grow them commercially in sub tropical southern Queensland Australia. They hill the soil up with a 2' base and about 1' high - paddock looks like corrugated iron - wave pattern. They then take cuttings (called slips about 50-60cm long) of vine from a pre-existing growing plant. These are planted (in the top part of the mound) horizontally into the soil with just the tip sticking out of the soil. Keep well watered the first week or two until the plant starts growing. Good rich soil to start with and then do not fert again especially with N. You want root development not vine production. If looking for cuttings/slips/tubers ask friends/neighbours/produce companies/internet sites etc or start a tuber as stated here.
