Black Spots on My Purpleleaf Willowherb Leaves

Spotting the Culprit: Recognizing Black Spots

👀 Early Detection

👁 Visual Symptoms

Black spots typically start as pinpricks under ⅛ inch in diameter. They're often surrounded by a yellow halo, a clear sign of trouble. As they grow, these spots can coalesce into larger, sunken or raised lesions that mar the beauty of your Willowherb.

🌿 Assessing Plant Health

Regular leaf check-ups are non-negotiable. Flip those leaves and inspect the undersides; that's where the black spots like to start their stealthy invasion. If you notice new growth being affected, it's time to take action—your plant is sending an SOS.
