If you are growing it for the fruit I doubt you have room enough. You will have to prune it so much to keep in the space I don't think you will get much fruit. If you like the flowers a dwarf Punica Granitum "Nana" will fit the space and be attractive without producing fruit in most cases. Al

Thanks for the reply. I quite like the idea of having some kind of fruit tree in this space. I understand there are types of dwarf fruit trees for certain kinds of fruit that do bear fruit. Does anyone have any suggestions on some kind of fruit that could be grown in this space.

I believe that Pomegranate can do fine with the size constraints you've described. Mine is growing in a narrow space between gazebo and greenhouse in partial shade of a huge pepper tree and is covered by a trumpet vine, and produces plenty of fruit every year.

They can, and will, get quite large with time. My uncle has an old tree on his property that is about 25 feet tall and about 25 feet wide or more at the canopy. They keep it pruned below and it had an umbrella-shape. However, if you water it less, it will stay a bit on the small side. Keep in mind that this tree was likely planted when the house was built in the 1930s. Pruning will help as well because they love to send out new shoots from ground level. Without proper removal of these vigorous shoots, the plant can become a messy thicket. Commercially grown pomegranates are usually kept about 8 feet tall and about 5 or 6 wide so I think that with proper pruning, your tree can stay within that size and fruit well for you.

Thanks for the additional replies which seem to suggest that IÂd be okay growing a pomegranate tree in that space. Actually I realized after posting that I know 2 people who have grown Pomegranate trees here (IÂm in San Diego). I spoke with both of them and they also think I should be fine with the space I have.

So I guess I will try it out and see how it goes. Thanks for everyoneÂs input.
