First blueberry bush
I would like to plant out (in a border, not a container) my first blueberry bush. As a new gardener, it's the first time I've bought something like this and I see I can buy them in various "litre" sizes (e.g. https://www.thompson-morgan.com/p/blueberry-chandler/cww3179TM). Is there any advantage to me going for the 3 litre over the 1.5 litre? Will the larger size just mean it's a bit more established and attractive to look at (which I'm not bothered about) or will it affect how soon I get fruit and quantities thereof?
