Scarlet pimpernel · Lysimachia arvensis

Why is my Scarlet Pimpernel dropping leaves?

It is less common for this plant to drop leaves, but it usually happens when the soil stays too wet for too long. Check your soil moisture first to see if the roots are sitting in water.

Check these first

  1. Feel the soil to see if it is soggy.
  2. Check the pot for drainage holes.
  3. Move the plant to a brighter location.

Likely causes

  1. Overwatering

    Possible

    How to tell: The lower leaves turn yellow or mushy before falling off. The soil feels constantly damp or soggy.

    What to do: Stop watering immediately and let the top 2 inches of soil dry out. Ensure your pot has drainage holes so excess water can escape.

  2. Low Light

    Possible

    How to tell: The plant looks stretched out and thin, and leaves drop from the bottom up. It is not getting enough energy to maintain its foliage.

    What to do: Move the plant to a spot with brighter, indirect light. If you are growing it indoors, place it near a sunny window.

When to worry

It is normal for the oldest bottom leaves to yellow and drop occasionally. Be concerned if many leaves fall at once or if the stems feel soft.

Stopping it coming back

Stick to a consistent watering schedule of every 3 to 7 days, and always check the soil before adding more water.
