Common wherever red cedar has colonised a fence line near apples — which in rural Hendricks and Boone counties is nearly everywhere. In Greenwood, two separate canopies in one city. The pre-1960 blocks around Old Town and near County Line Road hold Greenwood's only genuinely mature shade trees — just 9% of the housing stock predates 1960 — while the subdivisions east of I-65 are 2000s-era plantings still small enough to prune off a ladder. Ash is functionally gone: emerald ash borer has been confirmed in Indiana since April 2004 and is now in all 92 counties. Disfiguring rather than deadly.
Greenwood's canopy and what's at risk
Two separate canopies in one city. The pre-1960 blocks around Old Town and near County Line Road hold Greenwood's only genuinely mature shade trees — just 9% of the housing stock predates 1960 — while the subdivisions east of I-65 are 2000s-era plantings still small enough to prune off a ladder. Ash is functionally gone: emerald ash borer has been confirmed in Indiana since April 2004 and is now in all 92 counties.
What to look for
Orange gelatinous horns on cedar in spring; orange spots on apple and crabapple leaves.
Whether the tree can be saved
Disfiguring rather than deadly. It matters most to orchards and to anyone who wants a clean crabapple.
Timing in Johnson County
Fungicide on the apple side at bud break, or remove the cedars within a few hundred feet.
