I hadn't gotten any more replies to our questions so I'm posting a follow up
Now for Answers to our other questions on this tree
This year it produced berries and is drooping as shown would like to remove fruit, don't want any more trees? Can you help? , Will it flower/berry every year, if yes how to stop it? We live in Phoenix, AZ. Suppose it will destroy fence eventually,any pruning suggestions to prevent itwe'd like to keep it at about 15-20 feet so what time of year and how much to prune to train it to not get any bigger
We love the shade it provides!
Thanks for your invaluable time and efforts in giving us in site to it's care
