White horehound · Marrubium vulgare

Why is my white horehound drooping?

Drooping is less common for white horehound and usually happens when the plant is stressed by extreme heat or inconsistent watering. Check the soil moisture first to see if the plant is actually thirsty or if it is suffering from heat exhaustion.

Check these first

  1. Check if the soil is completely dry to the touch.
  2. Observe if the plant recovers after the sun goes down.
  3. Look for aphids that might be sucking sap from the stems.

Likely causes

  1. Extreme Heat Stress

    Most likely

    How to tell: The leaves wilt during the hottest part of the day but perk back up when the sun goes down.

    What to do: Provide a bit of afternoon shade if temperatures exceed 95 degrees. Ensure the plant has good air circulation to help it cool down.

  2. Severe Dehydration

    Possible

    How to tell: The leaves feel dry and brittle, and the soil has pulled away from the edges of the pot.

    What to do: Give the plant a thorough watering until water runs out of the drainage holes. Keep it out of harsh, drying winds until it recovers.

When to worry

It is normal for the plant to wilt slightly during the peak heat of a summer afternoon. You should worry if the plant stays droopy throughout the night and into the next morning.

Stopping it coming back

Maintain a consistent watering schedule and ensure the plant is in a spot with plenty of airflow. Avoid placing it in areas with stagnant, hot air.

Questions people ask

Should I mist my drooping white horehound?
No, this plant prefers dry conditions. Misting can encourage powdery mildew, which is a common problem for this species.
Why does my plant droop even when the soil is wet?
This is a sign of root rot, where the roots are too damaged to take up water. Check the roots for signs of decay immediately.
