Baby sage · Salvia microphylla

Why are my Baby sage leaves turning yellow?

It is less common for Baby sage to have yellow leaves, and it usually happens when the plant is sitting in soggy soil for too long. Check your soil moisture first to see if the roots are drowning.

Check these first

  1. Feel the soil depth to see if it is wet.
  2. Inspect the drainage holes for blockages.
  3. Check the underside of leaves for pests.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The leaves turn yellow and feel soft or mushy to the touch. You might also notice the soil stays damp for more than two weeks.

    What to do: Stop watering immediately and let the top 3 inches of soil dry out completely. If the soil is heavy, repot the plant into a mix with added perlite for better drainage.

  2. Nutrient deficiency

    Possible

    How to tell: Older leaves turn yellow while the veins stay green. This happens if the plant has been in the same pot for over a year without fresh soil.

    What to do: Apply a balanced liquid fertilizer diluted to half strength once in the spring. Avoid overfeeding, as this plant prefers leaner soil conditions.

When to worry

If the yellowing spreads rapidly across the whole plant, it is a sign of root rot. A single yellow leaf at the base is often just the plant shedding older foliage.

Stopping it coming back

Ensure your sage gets at least 6 to 8 hours of direct sun and only water when the top few inches of soil are dry.
