Is that because you have no suitable soil/land?
The trouble with pots is you have to control everything. The soil/compost has to be right, they have to be fed regularly, you have to make sure they are not too wet, but they don't dry out.
You can get it right, but it's easier in the soil,especially if you have to factor in work, holidays, etc.
