I care for a quince 'Aromatnaya' tree planted in Kansas City. This will be the third season it is in place. Conditions are a large raised bed about 18" deep with a mix of half compost and half topsoil. The tree is watered appropriately and is growing well. It has the growths seen in the photo. One suggestion was cedar apple rust. It had one fruit the first year and it deformed into one of these growths. Last summer more of them showed up on the branches and branch tips. The two fruit that set fell off in late June after a storm. Does anyone have an idea what is wrong and if there is a cure. My boss and I are confused and don't want to lose the tree but would rather remove it if needed when it is still manageable instead of doing the "let's see what happens" thing and it becomes a problem to get out.
