Fruit [Apple + Cherry + Plum] Trees in containers

[TrixC]

As mentioned by someone else I think lack of winter chill will be your main problem. Its not just about whether you get fruit or not, if the trees don’t get the necessary dormancy they will become stressed and prone to infection or death. And effective winter chill mean temperatures below 6 Celsius, which can realistically only be achieved outside. And that’s even before we get to pollination issues, and the challenges of leaf fall. I’m afraid I agree with the earlier poster that growing these varieties of trees inside is impractical. If I was going to grow a fruit tree indoors I’d probably choose a fig, or perhaps a pineapple guava. Citrus in my experience are quite tricky indoors as they need high humidity.

Should have really posted before buying the trees! Thanks for the advice everyone.
I'm just going to leave them be since I already paid for them and see how it goes.

When I lived in a south-facing flat we grew tomatoes two years in a row. I just used the seeds out of a supermarket cherry tomato. The plants were incredibly vigorous despite the relatively small pots and the fact I didn't even feed them. At the time I didn't know how to grow them. I knew to remove the sideshoots but didn't know I could remove the growing tip. They grew so tall I had to keep putting items of furniture in front for the plant to rest on. It was quite a sight! But they tasted fantastic.

Of course if I was doing that today I'd probably look for seeds from a dwarf cherry tomato like balconi red.

When we lived in that flat the people on the top floor had citrus fruits out in the hallway underneath a large skylight. They always seems healthy plants but I have no idea if they produced anything edible or not.
