Cherry tree never fruits
Most cherry varieties are self-sterile, meaning that they need a second tree that has compatible pollen and blooms at the same time as your tree, in order for pollination to occur. Please go to this website to determine which cherry variety will pollinate your cherry tree. http://extension.oregonstate.edu/wasco/cultivars. Click on the link entitled "Sweet Cherry Compatibility and Bloom Timing Chart". Find you variety on the chart and use any other variety in the same bloom timing column, but not in the same box. For example, if your tree is a Bing tree you can't use Royal Ann or Emperor Francis, but you could use Van, Rainier or Santina. If you purchase a pollinizor tree on a dwarfing or semi-dwarfing rootstock, you may get blooms on it as early as 2 or 3 years, but this means that it will be another 2 or 3 years before you get pollination taking place on your cherry tree. I hope this helps.
