About 4 years I contacted the OSU extension service about my newly planted fuyu persimmon tree which had about 25 fruits the first year, but they were small.  I was advised to pick the fruits off for the first few years to encourage the root system and structure of the tree to strengthen so it would support the weight of fruit in future years.  The next year I had only 5 blossoms and I picked the fruit off when very small.  Since then the tree has never blossomed (no fruit) although its leaves look very healthy except one small branch that appears dead and which I will prune off but have not yet done so.  The tree has grown in height.  I have watered regularly in summer months especially during excessive heat, and I've fertilized with 10-10-10.  I have read that Fuyus self-germinate and do not need a second tree to effectuate the blossom/fruit process, but it kind of seems like my tree is sterile.  Do you have any ideas for me?  I am in Beaverton, Oregon.
