Rough chervil · Chaerophyllum temulum

Why are my rough chervil leaves curling?

It is less common for this plant to have curling leaves, which usually happens due to heat stress or low humidity. Check the location of your plant to see if it is getting too much direct sun or dry air.

Check these first

  1. Check if the plant is in direct sunlight.
  2. Feel the leaves to see if they are dry or crispy.
  3. Look for nearby heat sources like vents or radiators.

Likely causes

  1. Heat Stress

    Most likely

    How to tell: The leaves curl inward and feel dry or crispy to the touch. This often happens if the plant is in a spot that gets too much afternoon sun.

    What to do: Move your plant to a shadier location where it gets partial to full shade. Increase your watering frequency slightly during hot spells to keep the soil consistently damp.

  2. Low Humidity

    Possible

    How to tell: The edges of the leaves curl and turn brown. This is common if the plant is near a heater or in a very dry room.

    What to do: Group your plant with others to create a more humid microclimate. You can also place a small tray of water and pebbles near the base of the plant to boost moisture in the air.

When to worry

If the entire plant is wilting and curling despite moist soil, it may be suffering from extreme heat damage. Minor curling on older leaves is normal as they age.

Stopping it coming back

Keep your rough chervil in a cool, shaded spot away from drafts. Maintain consistent soil moisture to help the plant handle temperature changes.

Questions people ask

Does rough chervil need high humidity?
It prefers moderate humidity. It does not need a greenhouse, but it will struggle in very dry, arid air.
Should I mist the leaves?
Misting does not provide much benefit and can encourage fungal issues like powdery mildew. It is better to use a pebble tray.
