Shothole—a condition characterized by small, round lesions or “holes” in the leaves—often appears in plants grown in nursery settings. While it’s a common issue in high-density production environments, it can raise questions for homeowners, landscapers, and property managers once plants are installed in the landscape. Understanding why shothole develops, and why it usually subsides after planting, can ease concerns and provide confidence in the long-term health of new plants.

Recently, a customer reached out with concerns about a few Cornus kelseyi (Kelsey's dogwood) plants they had just received from us. They noticed black spots on the leaves and wanted to ensure the plants were healthy. Their concern is entirely understandable—spotting disease on new plants can be alarming!
