I have two Lychee trees. One I grew from seed (not sure what kind it is) that is about nine years old. It has never produced, and a Emperor Lychee that I purchased 11 years ago. It was producing when I purchased it. I have had several crops from the Emperor. But for the last three years, it hasn't even flowered, let alone produced. It looks healthy.... but it isn't just my Lychee. I have two a couple of friends in the same neighborhood and their trees haven't produced or flowered either.... Is there something we can do to make sure that next spring. I thought maybe I had trimmed it at the wrong time of year, so last year I didn't even trim it.

Thanks for anybody who can help.
