I have a greenhouse Fina Sodea Clementine Mandarin growing in a 15 gallon Root Builder container. The tree is producing a higher quantity of blooms then I have previously ever seen on any of my citrus trees. Clementines are not self fertile, therefore, need to be cross pollinated with another variety to set a good crop. However, cross pollination causes seediness in the fruit. Therefore, I'm "pollinating" the blooms using a 10 PPM Gibberellic Acid spray. I purchased a pint bottle of ProGibb 4% gibberellic acid solution. To make a 10 PPM GA3 solution, only 1 gram of the concentrate is required per gallon of water. I guess I have enough ProGibb for some time. Anyway, almost 100 percent of the blooms have "set" small fruitlets. Of course many of the fruitlets will drop, but using gibberellic acid as a "pollinator" has worked beyond my expectations -- at lest so far. I have read literature that states citrus "pollinated" with gibberellic acid tend to produce smaller sized fruit, due to the very high number of fruit that the tree retains. Therefore, some thinning will probably have to be done in order to get standard size fruit. I am also using the spray to "pollinate" my Minneola Tangelo (another non self fertile variety), which is blooming at this time. The Minneola for now is also setting almost every bloom. I'll post results as they change. - Millet
