Should I cut off the yellow leaves?

Yes, you can snip them off with clean scissors. This keeps the plant looking tidy and helps you monitor for new yellowing.

Can low light cause yellow leaves?

Broad-leaved willowherb: yellow leaves, causes and fixes

Check these first

Feel the soil surface to check for dampness.
Inspect the drainage holes for blockages.
Look at the underside of leaves for signs of pests.

Likely causes

Overwatering
Most likely
How to tell: The lower leaves turn yellow and feel soft or mushy to the touch. The soil stays soggy for days after watering.
What to do: Let the top 2 inches of soil dry out before watering again. Ensure your pot has drainage holes so excess water can escape.
Nutrient Deficiency
Possible
How to tell: Older leaves turn yellow while veins remain green, often indicating a lack of nitrogen. This happens if the plant has been in the same soil for a long time.
What to do: Apply a balanced liquid fertilizer diluted to half strength once a month during the growing season. Repot the plant into fresh, nutrient rich potting mix if it has not been moved in over a year.

When to worry

A single yellow leaf at the base of the plant is normal aging. If multiple leaves turn yellow rapidly, you need to adjust your watering routine.

Stopping it coming back

Maintain a consistent watering schedule and ensure the soil never stays completely waterlogged.
