Potato growing bag and fertiliser

[cal]

Hi everyone

This year I have decided to try and grow potatoes. I have my grow bag and potato fertiliser at the ready.

However, I'm not sure how much fertiliser to add the bag (the potato fertiliser is from poundland) the box tells me to add 30g to a 20" pot. Should I add more than this to my bag or will that be enough?

Thanks for any advice.

How big is your bag?

Hi rustylady

The bag measures 17" by 15"

A handful is a useful measurement, stick one of those in the bottom half of the bag and mix it well.
