Pocket BotanistCheck these first
- Feel the soil to see if it is dry or soggy.
- Inspect the base of the plant for signs of a healthy host grass.
- Check for any sudden changes in the plant's environment.
Likely causes
Inconsistent watering
Most likelyHow to tell: The leaves turn yellow or crispy before dropping off the stem. The soil feels bone dry to the touch.
What to do: Water your plant every 3 to 7 days to keep the soil consistently moist. Do not let the soil dry out completely between waterings.
Host plant failure
PossibleHow to tell: This is less common for this plant, but it usually happens when the host grass dies or is removed. The bartsia loses its primary nutrient source and begins to shed foliage rapidly.
What to do: Check the health of the surrounding grasses in the pot or garden bed. If the host is dying, you may need to introduce a new, healthy grass to the root zone.

When to worry
A few old leaves falling from the bottom of the plant is normal, but widespread leaf loss is a sign of stress.
Stopping it coming back
Maintain a steady watering schedule and ensure the host grass remains healthy throughout the growing season.
