Grey alder · Alnus incana

Why is my grey alder drooping?

It is less common for a grey alder to droop, which usually points to a sudden change in water availability or extreme heat stress. Check the soil moisture immediately to see if it needs a drink.

Check these first

  1. Check the soil moisture level.
  2. Look for signs of wilting during the hottest part of the day.
  3. Inspect the plant for any signs of root damage.

Likely causes

  1. Water stress

    Possible

    How to tell: The stems lose their rigidity and the leaves hang downward. The soil will likely feel dry and pull away from the edges of the pot.

    What to do: Give the plant a deep soak immediately. Ensure the soil is damp but not waterlogged, and monitor it closely for the next 24 hours.

  2. Heat stress

    Possible

    How to tell: The plant droops during the hottest part of the day but perks up at night. This happens when the plant loses water faster than it can absorb it.

    What to do: Move the plant to a spot with partial shade during the afternoon. Ensure it receives bright, indirect light for the rest of the day.

When to worry

Worry if the plant does not recover after a thorough watering. If the stems remain limp overnight, the root system may be struggling.

Stopping it coming back

Maintain a consistent watering rhythm and protect the plant from intense, direct afternoon sun.
