Arbequina olive tree
After an extensive search on the web I am back to the forum...
I obtained what I think is a Arbequina olive tree. Currently it's about 2 feet tall and growing on a single trunk. I planted it near the corner of my house where it gets afternoon sun from the southwest. From what I can tell the tree will get to be about 15-20 feet when mature but I can prune it to whatever size (or so I read). Ultimately I want to keep it the same height as my dwarf citrus when they mature so between 10-12 feet. I'm more worried about the root system. Like my dwarf Dancy Tangerine and Wonderful Pomegranate, I planted the olive tree 2 feet from the house.
I can't find any information on the root system of this tree other than it is shallow and I've read extensive information on growing them in pots, so it seems like it would be okay. Will I run into foundation problems with it being this close to the house? If I'm totally crazy for planting it close to the house, should I dig it up, pot it and bury the pot to act like a root barrier? How long would that last?
