Common figwort: spots, causes and fixes

Check these first

Inspect the undersides of the leaves for white dust.
Check if the plant is crowded by other vegetation.
Feel the soil to see if it has been staying too wet.

Likely causes

Powdery mildew
Most likely
How to tell: You will see a white, floury substance covering the leaves and stems. It usually starts as small patches before spreading across the plant.
What to do: Remove the most heavily affected leaves to reduce the spore count. Spray the remaining foliage with a mixture of one tablespoon of baking soda in a gallon of water. Ensure you improve air circulation around the plant to prevent recurrence.
Leaf spot disease
Possible
How to tell: These appear as dark, distinct circular spots with yellow halos. They often develop after periods of heavy rain or overhead watering.
What to do: Prune away infected leaves immediately and dispose of them in the trash, not your compost pile. Avoid watering from above to keep the leaves dry. Apply a copper based fungicide if the infection continues to spread.
