Common centaury · Centaurium erythraea

Why are my common centaury's leaves curling?

It is less common for this plant to have curling leaves, which usually happens when the plant is not getting enough light or is reacting to extreme heat. Check your light levels first to ensure the plant is getting enough sun.

Check these first

  1. Assess the light levels in the current spot.
  2. Check if the soil is dry or waterlogged.
  3. Look for signs of heat damage on the leaves.

Likely causes

  1. Insufficient light

    Possible

    How to tell: The leaves curl inward and the stems look stretched or leggy.

    What to do: Move your plant to a spot that receives full, direct sun. This plant thrives in bright light and will struggle in dim corners.

  2. Heat stress

    Possible

    How to tell: The leaves curl during the hottest part of the day to conserve moisture.

    What to do: Ensure the plant is watered correctly and move it to a slightly cooler spot if temperatures are consistently above 85 degrees.

When to worry

Worry if the curling is accompanied by yellowing or wilting that does not recover at night. Minor curling during the hottest part of the day is often just a natural reaction to heat.

Stopping it coming back

Provide plenty of direct sunlight and keep the soil moisture consistent.
