I recently planted a dogwood tree in Berkshire County, MA. I planted it 4 days ago and I've noticed spotting on the bottom leaves (see pictures attached). Is this anthracnose? Is it possible that the tree is already infected only after being planted 4 days ago? There was no spotting on the leaves when I bought it from a nursery a few days ago.
Is there a way to treat this? Or should I try and return the tree (one year warranty).
