I had never heard of a tree tomato before moving to Kenya back in 2005. They are popular here and can be found all over the place. I do not care for the taste of the fruit, but the children enjoy them.
We planted one on The Shire and may end up giving it a buddy as well. Unfortunately I have since learned that the tree does not have deep roots and has weak branches. Meaning it does not do well in windy areas, and we have a high windy season there on The Shire. So we will not be investing much time and effort into the tree tomato.
