American germander · Teucrium canadense

Why is my American germander dropping leaves?

It is less common for this plant to drop leaves, but it usually happens when the soil stays too wet or the plant is stressed by sudden environmental changes. Check the soil moisture level first to see if the roots are sitting in water.

Check these first

  1. Feel the top inch of soil for moisture.
  2. Inspect the drainage holes for blockages.
  3. Check the plant location for recent changes.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The lower leaves turn yellow or mushy before falling off, and the soil feels constantly soggy. You might also notice a sour smell from the pot.

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

  2. Light Shock

    Possible

    How to tell: Leaves drop suddenly after you move the plant to a new spot with significantly different light levels. The remaining leaves may look dull or wilted.

    What to do: Move the plant back to its original location or transition it to new light very slowly over 2 weeks. Keep it away from drafty windows or heating vents.

When to worry

A few leaves dropping after a move is normal, but losing more than 20 percent of the foliage at once is a sign of serious root distress.

Stopping it coming back

Water only when the top inch of soil is dry and keep the plant in a spot with consistent light.

Questions people ask

Will my plant grow back the lost leaves?
Yes, once the underlying issue is fixed, the plant will produce new growth from the nodes where leaves were lost.
Should I fertilize a plant that is dropping leaves?
No, avoid fertilizing until the plant shows signs of new, healthy growth. Adding nutrients to a stressed plant can burn the roots.
