I have a sweetheart, a Mauritius, a Hak Ip, a Brewster and an Emperor. From what people tell me, my Emperor should be the hardest to get to flower and fruit. For whatever reason here in Orlando, it's my most reliable producer by far. The darn thing blooms and fruits every year. I've got a ton of flowers so far this year. For the other varieties, nada. What am I doing wrong? Isn't the Brewster supposed to be one of the most reliable producers?
