Purple moor grass · Molinia caerulea

Why is my Molinia caerulea drooping?

It is less common for this grass to droop, but it usually happens when the plant is not getting enough water or is struggling with extreme heat. Check the soil moisture first to see if it is bone dry.

Check these first

  1. Feel the soil to see if it is dry to the touch.
  2. Move the plant to a cooler location for a few hours.
  3. Check if the plant has been in direct sun for too long.

Likely causes

  1. Underwatering

    Most likely

    How to tell: The blades look thin, brittle, and start to lean over. The soil will feel dry and pull away from the edges of the pot.

    What to do: Give the plant a thorough soaking until water runs out of the drainage holes. Keep the soil consistently moist by checking it every 3 days during hot weather.

  2. Heat Stress

    Possible

    How to tell: The grass wilts during the hottest part of the day even if the soil is moist. The leaves may look slightly curled or faded.

    What to do: Move the plant to a spot with partial shade during the afternoon. Mist the foliage lightly or increase humidity to help the plant recover from the heat.

When to worry

Drooping is usually a temporary reaction to thirst or heat. If the plant stays limp after a deep watering, the root system may be damaged.

Stopping it coming back

Keep the plant in a spot that avoids harsh afternoon sun. Maintain a consistent watering schedule to keep the soil evenly moist.
