Why is my Black-eyed Susan drooping?

Drooping is often the plant's way of telling you it is thirsty or struggling with the heat. Check the soil moisture immediately to see if it has dried out too much.

Check these first

  1. Stick your finger an inch into the soil to check for moisture.
  2. Check if the drooping happens only during the hottest part of the day.
  3. Look for signs of wilting even when the soil is damp.

Likely causes

  1. Underwatering

    Most likely

    How to tell: The leaves and stems look limp and feel dry to the touch. The soil surface feels hard and pulls away from the edges of the pot or garden bed.

    What to do: Give the plant a deep, thorough watering until the soil is moist 2 to 3 inches down. Maintain a schedule of watering every 5 to 10 days depending on the heat.

  2. Heat Stress

    Possible

    How to tell: The plant droops during the hottest part of the afternoon but perks up again in the evening. This is a temporary reaction to intense sun.

    What to do: Apply a 2 inch layer of mulch around the base of the plant to keep the roots cool. Ensure the plant is getting enough water to handle the high temperatures.

When to worry

It is normal for plants to wilt slightly in extreme afternoon heat. Worry if the plant stays wilted even after the sun goes down or after you have watered it.

Stopping it coming back

Mulch the soil to retain moisture and keep the roots cool. Water consistently during the first growing season to help the plant establish a strong root system.
