I bought this thing close to a decade ago. When I got it it had about 6 or 7 lemons on its already. They eventually matured, and I harvested them. I was excited cause its was the first successful citrus harvest I ever had. Since then, it flowers significantly, the house smells great, but no fruit . I think once I got a single fruit. Its did have a companion, which died last year. Anyway, over the summer, it had 2 flowers. In the past I hand pollinated ( obviously unsuccessfully), bit this year I put the flowering tree near the Bee house. The flowers dropped, so I figured no success. When I bring it inside it is very messy as the hundreds of dried flowers drop along with many leaves due to the shock. I finally gave the tree an ultimatum. No fruit, you spend the winter in the garage and what ever happens, happens . To my delight I found this grape sized fruit on the plant. Hopefully it matures. Im afraid the season change, and going from outside to inside may shock the plant and drop the fruit.
