Why are my Redshank leaves turning yellow?

Yellowing leaves are less common for Redshank and usually point to issues with soil moisture or nutrient levels. Check the soil dampness first to see if you are overwatering or underwatering.

Check these first

  1. Touch the soil to see if it is soggy or bone dry.
  2. Inspect the underside of the leaves for tiny pests.
  3. Check if the pot has proper drainage.

Likely causes

  1. Overwatering

    Possible

    How to tell: The leaves turn yellow starting from the bottom of the plant and the soil feels constantly soggy. You might also notice a slight musty smell from the pot.

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

  2. Nutrient Deficiency

    Possible

    How to tell: Older leaves fade to a pale yellow while the veins stay green. This happens when the plant has exhausted the nutrients in its potting mix.

    What to do: Apply a balanced liquid fertilizer diluted to half strength once every 4 weeks during the growing season. Do not fertilize during the winter months.

When to worry

Worry if the yellowing spreads rapidly to new growth. It is normal for the very oldest bottom leaves to yellow and fall off as the plant grows.

Stopping it coming back

Keep the soil consistently damp but never waterlogged to maintain healthy foliage.
