Smooth sumac · Rhus glabra

Why is my Smooth sumac drooping?

Drooping in Smooth sumac often signals that the plant is struggling to move water to its leaves. Check the soil moisture levels first to see if the plant is thirsty or if the roots are sitting in too much water.

Check these first

  1. Feel the soil 3 inches down to check for moisture.
  2. Inspect the branches for any signs of dark discoloration or streaks.
  3. Check if the drooping happens only during the hottest part of the day.

Likely causes

  1. Verticillium wilt

    Most likely

    How to tell: You will notice individual branches wilting suddenly while the rest of the plant looks fine. If you cut into a branch, you might see dark streaks in the wood.

    What to do: Prune out the affected branches well below the wilted area, sterilizing your shears with alcohol between every cut. Unfortunately, there is no cure for this soil fungus, so keep the plant hydrated to help it manage stress.

  2. Underwatering

    Possible

    How to tell: The leaves will look limp and feel dry to the touch, especially during hot summer weeks. The soil around the base will be cracked and very dry.

    What to do: Give the plant a deep soak by letting a hose trickle at the base for 30 to 60 minutes. Moving forward, ensure it gets a deep watering every 7 to 14 days during its first few years.

When to worry

If the wilting spreads to the entire plant or the main trunk, the plant likely cannot be saved. Temporary drooping on very hot afternoons is normal if the plant recovers by morning.

Stopping it coming back

Avoid planting sumac in areas where previous plants died from wilt, and keep the root zone mulched to maintain consistent moisture.
