We planted two Bing cherry trees in our yard....ahhh...let me rephrase that.... Ott, E. planted two Bing cherry trees in our yard. (Whew, that got me out of trouble quick.) Anyway, we had been wanting to plant some fruit trees and finally decided on cherry. While we were shopping for trees I learned something that I wanted to share with you. Tart Cherry trees are self pollinating, so you only need one and it will produce fruit just fine. (You can have more than one too.) Sweet cherry trees are cross pollinating so they need to be planted in groups of two or more if you want them to produce fruit. Just thought I would pass that tid-bit of information along to you in case you too were in the market for fruit trees.
