Your better off with holes in the ground depending on local soil quality or how hard it is to dig there. I'd prolly justget an auger and dill holes and fill with proper soil in any case even if the soil sucked and was clayed up and hard to dig. The main benifit of pots in my eyes are that you can move them around. They require much more watering. Can get potbound and limit yield, can be challenging to keep roots cool in some enviorments.
