Ornamental Crabapple Leaves Yellowing
Hi, I'm in Calgary and this past week I've noticed that some of the leaves on my ornamental crabapple are yellowing and it's prematurely dropping apples. I thought maybe it just needed more water, so I have deep watered it, but more and more leaves are yellowing. Has anyone had experience with this and know what might be the problem?
I looked online and there is something called Apple Scab? But I'm not sure if that's what I'm seeing. The apples that have dropped don't appear to have any spots on them. If it is, can a fungicide be sprayed to save the tree? Would I need to call an arborist? Or could this be because of the crazy winter we had? I'm pretty new at all this and am still learning!
I'm attaching a few photos.
Thanks in advance for any suggestions!
