Sea Thrift · Armeria maritima

Why are my Sea Thrift leaves turning yellow?

It is less common for Sea Thrift to have yellow leaves, and this usually happens when the soil stays too wet for too long. Check your soil moisture first to see if the roots are sitting in water.

Check these first

  1. Feel the soil surface for dampness.
  2. Check the bottom of the pot for standing water.
  3. Inspect the base of the plant for mushy stems.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The leaves feel soft or mushy and the soil remains damp for days after watering.

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

  2. Poor Drainage

    Possible

    How to tell: Water pools on the surface of the soil or the pot feels heavy for a long time.

    What to do: Repot your plant into a gritty, well draining cactus or succulent mix. Add perlite or coarse sand to improve airflow around the roots.

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 natural aging.

Stopping it coming back

Always allow the soil to dry out slightly between waterings to keep the roots healthy.

Should I cut off the yellow leaves?
Yes, you can snip them off with clean scissors to keep the plant looking tidy. This also helps you monitor if new leaves are turning yellow.
