PlantPalWet-looking spots that keep growing
A spreading, water-soaked mark can be a sign of bacterial leaf spot. Similar damage has other causes.
What to check first
Look for translucent, dark or greasy-looking spots that expand. Some have a yellow border or stop at veins. Check the pattern across several leaves rather than judging by one spot.
What to do now
Separate a movable plant and water at soil level. If only a few leaves are severely affected, remove them with clean tools and disinfect the blades before using them on another plant.
What to watch next
If wet spots multiply quickly, reach the stems or cause leaves to collapse, seek plant-specific advice. Take photos before removing more leaves.
