Check these first
- Examine the spots for yellow halos or concentric rings.
- Check if you have been watering the leaves directly.
- Look for signs of poor airflow around the plant.
Likely causes
Bacterial Leaf Spot
Most likelyHow to tell: These appear as small, dark, water-soaked spots that may have a yellow halo. They often lead to leaf drop if the infection is severe.
What to do: Remove and destroy all infected leaves immediately to stop the spread. Avoid overhead watering and ensure your plants have plenty of airflow.
Fungal Leaf Spot
PossibleHow to tell: These spots are usually circular with concentric rings or a tan center. They thrive in humid, rainy weather.
What to do: Apply a copper-based fungicide according to the label instructions. Keep the area around the base of the plant clean of debris.

When to worry
If the spots are spreading rapidly and causing leaves to fall off, your harvest is at risk. A few isolated spots on older leaves are usually not a major concern.
Stopping it coming back
Water only at the base of the plant and keep the foliage dry. Space your plants 18 to 24 inches apart to encourage good air circulation.
