Hi, there, heavily, alternate years. Last year we harvested about 700 'cots from our semi dwarf tree, all fruit of good commercial size. With the persimmon, from what I have read in CRFG's Fruit Gardener," persimmons, especially the Fuyu, do so, as well. I have been considering thinning our Panamint nectarines, but will enjoy eating/canning them, no matter what the size. That tree is 3 years old and is so loaded that it's branches are beginning to sag, even with fruit no larger than a good sized olive. We shall wait and see. First we need to get about netting the apricot and nectarine, so that the birds do not devour every last fruit...as they did, last year, the day our blueberries ripened:( Needless to say, they are netted this year! Ya know, pecans can technically probably be considered a fruit, since they are the seed kernels of a fruit. Dunno. Any botanists out there? Happy growing! Ron
