Judas tree · Cercis siliquastrum

Why is my Judas tree showing signs of root rot?

Root rot is less common for this tree, but it usually happens when the soil stays soggy for too long. Check the soil drainage around the base of your tree first.

Check these first

  1. Feel the soil moisture 3 inches deep.
  2. Inspect the area for standing water after rain.
  3. Check the base of the trunk for soft or discolored bark.

Likely causes

  1. Poor soil drainage

    Most likely

    How to tell: The ground feels constantly squishy or water pools around the trunk after rain. You might notice the tree looking generally weak or stunted.

    What to do: Improve the soil structure by mixing in organic compost or grit to help water move away from the roots. Avoid watering if the top 3 inches of soil are still damp.

  2. Overwatering

    Possible

    How to tell: Leaves may turn yellow or drop prematurely while the soil remains wet. The roots themselves will look mushy and dark instead of firm and light colored.

    What to do: Wait until the top 3 to 4 inches of soil are dry before giving the tree a deep soak. Ensure the planting site is not in a low spot where water collects.

When to worry

If you see large sections of the canopy dying back or the trunk bark feels soft, the damage may be severe. It is normal for a tree to lose a few leaves during a very wet spring.

Stopping it coming back

Plant your Judas tree in well draining soil and avoid adding extra water during periods of heavy rainfall.

Questions people ask

Can I save a tree with root rot?
If caught early, you can improve drainage and reduce watering to help it recover. If the rot has reached the main trunk, the tree is likely beyond saving.
How often should I water a young Judas tree?
Water it deeply every 7 to 14 days during dry spells. Always check the soil moisture before adding more water.
