Indoor "dwarf" fruit trees

I recieved a catalog in the mail from the Burgess Seed & Plant Co, they also are online. There were quite a few things that caught my interest, and some things they have literally made me think "how could they possibly do that?", but we can get to that later on

What peaked my interest were these:

[url=https://eburgess.com/detail.asp?nav=hps&pid=1127]Dwarf Tangerine[/url]

Now according to them, these should fruit within the first year and all can be indoor plants (although I would of course put them out in the sun during the summer). I'm wondering what you all think about these, are they really what they say they are? Are the fruit really edible?

In general a dwarfing rootstock makes them fruit earlier in life. So the very dwarfing could fruit within the first year BUT if they did I suggest that anyone limit the number of fruit. Amazes me how many expect a 1-2 years old tree to produce as much fruit as a large mature tree.

The tangerine should make a good indoor tree, not sure about the lemon and the blueberry. The lemon would I say benefit from overwintering in a unheated room. Temp would drop down but not freeze. Blueberry's I would say need an outdoor life.

All 3 will benefit from some "cold" period. I would have thought that the lemon and the blueberry would most certainly.

They all originate from places that have seasons and dormant periods and so would benefit this being maintained.

Thanks for that information. What kind of difficulty level are dwarf trees on? Will I have to keep a good eye on them, provided I have adequate sun and water?
