Hello all. I'm trying to solve a mystery in my backyard. We moved in back in December, and the seller told us "oh, you will love the pear tree. The fruits are so delicious!" There are three pear trees in the yard (two on our side of the fence and one neighbor's hanging over the fence). I think one or two may be ornamental not fruiting, but how do I tell? All three have fruit, but I understand Bradford pears can have small marble sized hard fruits. I've been watching to try and figure when to thin. Two bloomed (smelly!) and fruited earlier, the other bloomed later (also kind of smelly, but taller tree so I couldn't tell how stinky). The earlier bloomers have larger fruits now, of course. What are the ways to ID? Don't want to miss my thinning chance. Also appear to have rust, but am trying to avoid heavy duty sprays.
