so I just got this baby meyer lemon tree from lowe’s and this is my first one so i have absolutely no idea what to do with it. I know I have to repot it, what would be the best soil mix to do that?? I read it needs a well draining soil so like topsoil and sand? also how often should i be fertilizing it?? Any tips for growing these in containers? Is it safe to go ahead and repot it in a huge container or should i get one just a little bigger than this one?

I live in iowa zone 7b so i know i already have an uphill battle ahead of me, combined with the fact that these are apparently very finicky trees 😭 i appreciate all the help I can get!!!!
