Woodland sage · Salvia nemorosa

Why are my Salvia nemorosa leaves turning yellow?

It is less common for this plant to have yellow leaves, which usually happens due to overwatering or poor drainage. Check the soil moisture level 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 if the plant is in a low spot in the garden.
  3. Examine the roots for signs of rot.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The lower leaves turn yellow and feel soft or mushy. The soil stays wet for more than two weeks.

    What to do: Stop watering immediately and let the top two inches of soil dry out. Ensure your planting site has excellent drainage and is not in a low spot where water pools.

  2. Nutrient Deficiency

    Possible

    How to tell: Older leaves turn pale yellow while the veins remain green. This happens if the soil is very depleted.

    What to do: Apply a balanced, slow release fertilizer once in early spring. Do not overfeed, as this can lead to weak, floppy growth.

When to worry

A few yellow leaves at the base of the plant are normal as it ages. Worry if the yellowing spreads rapidly to the top of the plant or if the stems become soft.

Stopping it coming back

Plant your sage in well draining soil and avoid watering more than once every seven to fourteen days. Make sure the crown of the plant stays above the soil line.

Questions people ask

Does my sage need more water?
Usually, no. Woodland sage prefers to dry out between waterings, so yellowing is almost always a sign of too much water rather than too little.
Should I cut off the yellow leaves?
Yes, you can trim them off with clean shears. This keeps the plant looking tidy and helps you monitor if the yellowing continues.
