I have a couple of 16 foot beds where I could plant this as top soil is 18 inches deep ! old privy bed ! how many could I squeeze in ?

Typo corrected for search purposes.

Depends how wide the bed is.

Plants like to be ideally 18 ins apart

I have a 12' x 4' raised bed with 22 plants and they are very happy.
