Spotting the Trouble: Recognizing Black Spots on Your Plant

🕵️ Visual Cues: The Look of Trouble

Tiny invaders often less than ⅛ inch in diameter, black spots on Houghton's Hybrid leaves are the party crashers you didn't invite. They're dark, they're stubborn, and they're not just a surface issue. Check both sides of the leaves; these spots love to start their shenanigans on the undersides.

Yellowing leaves often accompany these spots, signaling that your plant is definitely not having a good time. Keep an eye on their growth; a small spot today could be a full-blown disaster tomorrow.
