Hello! I am looking for a fruit tree for my front yard. I want it to stay fairly small so I don’t lose the sun in the rest of my vegetable garden. I live in Portland, my home faces south, the tree would go in the southeast corner of the yard amidst blueberries strawberries tomatoes etc. in other words lots of sun. I currently have a cocktail plum in that space. It was purchased about 4 years ago and is riddled with problems and appears to be slowly dying despite many attempts to prune, fertilize, fill it with ladybugs to address aphids etc. the grafts just weren’t done well and the shape of the tree isn’t supporting the fruit etc. I’m over it. I’d like another plum, peach, apricot, or persimmon (leaning persimmon), but I want it to thrive and give delicious fruit. Maybe others if you recommend. What would do best with the least pest issues, be relatively low maintenance, and be preferably drought resistant with a deep tap root to avoid sucking the water from the surrounding veg garden? Also, where is the best place to buy said tree? Preferably an older tree. Cost is less of a concern than quality. Thank you kindly in advance.
