I am assuming you intend to grow them in pots and you are asking whether to fill the pots with garden soil or compost.
Well it is a big NO to garden soil!
In terms of compost you would be better growing them in John Innis No 3 which is a SOIL based compost, rather than a run of the mill potting compost.....Tg
Just noticed the latter part of your question re potato compost. Personally I wouldn't risk it although I respect you want to economise!
What you could do is fill the bottom third of the pot with the the potato compost, mix a handful of bonemeal in it before you do, then fill the top two thirds with Ji 3
