Antik Geranium advice

Hi,

I love the Antik 'climbing' variety of geranium, so stunning. I know they are not actually climbers but every google search seems to refer to them as such.

I usually buy a mature plant which is rather expensive but last year I purchased some young plants in hope they would grow in spectacular fashion. Sadly that didn't happen and they are supposed to grow fast and tall. Mine didnt grow very much but did flower.

I have one which survived inside during the winter and I am looking for advice on how to best care for it. What kind of feed and soil?

On another note I did ask the all knowing chatGBT and it has never heard of them. So much for AI.

Thanks

 

Neither are they actually geraniums they are pelargoniums, this page from the RHS might help

Thank you, that explains why I couldn't find any information.
