Catalpa

Why is my Southern catalpa wilting and drooping?

Drooping leaves on a Southern catalpa can be a sign of simple thirst or something more serious like a soil fungus. Check the soil moisture first to see if the ground is bone dry or waterlogged.

Check these first

  1. Check the soil moisture with your finger or a trowel.
  2. Look for branch dieback on only one side of the tree.
  3. Examine the bark for any unusual discoloration.

Likely causes

  1. Verticillium wilt

    Possible

    How to tell: Branches will wilt and die back, often starting on one side of the tree. If you peel back the bark, you may see discolored streaks in the wood.

    What to do: There is no cure for this soil fungus. Focus on keeping the tree hydrated and fertilized to help it fight the infection, and prune away dead branches to prevent further spread.

  2. Severe drought stress

    Most likely

    How to tell: The leaves look limp and tired, especially during the hottest part of the day. The soil feels dry and cracked several inches down.

    What to do: Give the tree a deep, slow soaking once every 7 to 14 days. Ensure the water reaches at least 12 inches into the soil to encourage deep roots.

When to worry

If the wilting is sudden and affects large branches, it could be Verticillium wilt, which is serious. If it is just the whole tree looking sad on a hot afternoon, it is likely just thirsty.

Stopping it coming back

Avoid overwatering, which can stress roots, and keep the tree well mulched to maintain consistent soil moisture.

Questions people ask

How do I know if it is just thirsty?
If the tree perks up after a deep watering, it was just thirsty. Wilt caused by disease will not improve with water.
Should I fertilize a drooping tree?
Wait until you are sure it is not a disease. Fertilizing a stressed tree can sometimes make things worse.
