It depends on what sort of soil or growing medium you have available...not sure what your available dirt is. I assume you are planning on planting in containers, yes?
For me personally, where I live the soil is very rich (lots of trees and rain) so I've several times dug up dirt from my side yard for containers. Or I will use a purchased potting soil and mix in compost. My own, or commercially bought organic.
I don't often use fertilizers since I am lucky, dirt-wise.

If your available soil is poor, amending it with compost or other organic materials will surely help. In most of the US we have resources available to analyze our soil and correct for definciencies if necessary.
Can you purchase commercial potting soil where you live? Sorry if that is a stupid question. If you can, that is what I would use. And maybe some sort of fertilizer during blooming and fruit production although that is certainly not mandatory IMHO.
