pot grown citrus tree and apple tree - help

soffie

hi, we got these off yougarden
https://www.yougarden.com/item-p-680021/orange-and-lemon-collection-with-feed
6.5lr pot large orange 'navelina' tree & a apple discovery in 5lr pot.
basically, these have been in the pots they came in for nearly 3 weeks now.. when should i move them to their big pots?
the leaflet we got with them was generic and said 2-3 weeks time but i am unsure as it is a generic leaflet.
also with the citrus orange tree is it ok to bring in winter without sunlight? basically no where we can put it will have sunlight on it. its just not possible based on where we put everything in house. so im not sure what to do.. whether to leave it outside or bring it in but basically now have no sunlight? any help here would be awesome!!
i now know what soil/compost to use but just need to understand finer details as above. thankyou

This was a very similar recent question https://forums.moneysavingexpert.com/discussion/6048049/apple-tree-and-orange-tree which includes links to (hopefully) useful information. The orange tree will need light and protection from frost during the winter. Sorry.
