Sweet Marjoram · Origanum majorana

Why is my sweet marjoram dropping leaves?

It is less common for sweet marjoram to drop leaves, and this usually happens due to sudden changes in light or temperature. Check your plant's location first to ensure it is getting enough consistent sunlight.

Check these first

  1. Check the soil moisture with your finger.
  2. Observe the plant's light exposure throughout the day.
  3. Inspect the stems for any mushy or dark spots.

Likely causes

  1. Insufficient Light

    Most likely

    How to tell: The stems become long and spindly, and the lower leaves turn yellow before falling off. This happens when the plant does not receive at least 6 hours of direct sun daily.

    What to do: Move your marjoram to a south facing window or an outdoor spot with full sun. If you are growing it indoors, consider adding a grow light to supplement the natural light.

  2. Overwatering

    Possible

    How to tell: The leaves may look wilted or mushy before they drop, and the soil stays damp for more than a few days. Check the base of the stems for any signs of rot.

    What to do: Let the top inch of soil dry out completely before you water again. Ensure your pot has drainage holes so excess water can escape.
