well yes definatly unless you wantit every wear . you can bury the pot if you want to hide it and have other herbs near it close to your kitchen .

Soil or compost, but generally compost has more nutrients. Sadly when i first planted mine I didn't know that they should be in a pot and well now when i cut the grass it smells very minty...

I made thew mistake of planting mint in the garden and it springs up everywhere. I am forever pulling it up.

Sometimes when I am pulling it up, it is like following a wire along the garden with the roots.

Definitely pot it up.

Soil on its own tends to go hard and compact in pots so either the mix or pure compost would be OK, its not fussy.
