Heath rush · Juncus squarrosus

Why are my Juncus squarrosus leaves turning yellow?

It is less common for this plant to yellow, usually caused by the soil drying out too much or poor drainage. Check the moisture level of your soil immediately to see if it has gone dry.

Check these first

  1. Touch the soil to see if it feels dry or soggy.
  2. Inspect the drainage holes to ensure they are not blocked.
  3. Check the base of the stems for any signs of rot.

Likely causes

  1. Drought stress

    Most likely

    How to tell: The tips or entire blades turn yellow and crisp because the plant is not getting enough water.

    What to do: Water your rush thoroughly until the soil is saturated. Keep the soil consistently damp by watering every 2 to 5 days, never letting the top inch dry out.

  2. Waterlogged soil

    Possible

    How to tell: The leaves turn a sickly yellow and the base of the plant feels mushy.

    What to do: Ensure your pot has drainage holes so excess water can escape. If the soil is sitting in standing water, empty the saucer or decorative pot immediately.

When to worry

If the yellowing spreads rapidly across the whole plant, it is a sign of severe root distress. It is normal for the oldest, lowest leaves to yellow and die back as the plant grows.

Stopping it coming back

Maintain a strict watering schedule that keeps the soil constantly damp at all times.
