My family doesn't really care for their gardening and randomly thrown food scraps under our orange tree. 4 years ago an avocado seed they tossed grew into a tree and looks healthy to this day but there's little room left for it to grow.
I just moved back home from college and have been trying to get into gardening. This is one of the first gardening projects I'm taking on. I found a page talking about how to transplant a tree (I can't post the link since I'm a new member) but I don't know how big the root ball of an avocado tree is, how to find it, or how to find where it ends. I tried digging a few feet away from the base of the tree but found thick roots that I think belong to it.
I live in northern California but am also willing to transplant it into a large pot and keep it indoors if the weather isn't best for transplanting.
What do you recommend? What do I do about the roots, should I cut them?
