Crabapple is the most-planted small tree in central Indiana subdivisions and it generates more "is my tree dying?" calls than anything else its size — because scab-susceptible cultivars go yellow and defoliate in July and August every single year while remaining perfectly alive. Most of these calls end in a spray program or a replacement conversation, not a removal.
