Wood sage · Teucrium scorodonia

Why are my Wood sage leaves turning yellow?

Yellow leaves are less common for this plant and usually point to an issue with light exposure or nutrient balance rather than a disease. Check if your plant is getting enough indirect light to support its growth.

Check these first

  1. Observe the light levels in the current location.
  2. Check the soil for signs of extreme dryness or compaction.
  3. Look for pests on the undersides of the yellowing leaves.

Likely causes

  1. Inconsistent Light

    Possible

    How to tell: Leaves on the side facing away from the light source turn yellow and drop off.

    What to do: Move your plant to a spot with consistent partial shade or full sun. Rotate the pot every week to ensure all sides receive equal light.

  2. Nutrient Deficiency

    Possible

    How to tell: Older leaves turn yellow while the veins remain green, indicating a lack of nitrogen or iron.

    What to do: Apply a balanced liquid fertilizer diluted to half strength once a month during the growing season. Avoid overfeeding, as this can burn the roots.

When to worry

It is normal for the oldest leaves at the base to yellow and fall off as the plant grows. Be concerned if the yellowing spreads rapidly to new growth.

Stopping it coming back

Keep the plant in a stable environment with consistent light and regular, balanced feeding.
