Marsh woundwort: yellow leaves, causes and fixes

Check these first

Check the soil moisture with your finger.
Inspect the undersides of leaves for pests.
Ensure the pot has proper drainage holes.

Likely causes

Underwatering
Most likely
How to tell: The soil feels dry to the touch and the leaves look brittle or limp before turning yellow.
What to do: Water the plant thoroughly until water drains from the bottom. Maintain a consistent schedule so the soil stays damp, checking it every 2 days.
Nutrient Deficiency
Possible
How to tell: Older leaves turn yellow while the veins remain green, often indicating a lack of nitrogen.
What to do: Apply a balanced liquid fertilizer diluted to half strength once a month during the growing season. Ensure you are not overwatering, as this can also prevent nutrient uptake.
