Arborvitae · Thuja

Why is my Thuja drooping?

Drooping is less common for this plant, and it usually happens when the roots are struggling with too much water or heavy, compacted soil. Check the drainage around your tree immediately to ensure the roots are not sitting in mud.

Check these first

  1. Dig a small hole near the root ball to check for standing water.
  2. Smell the soil for a musty or rotten odor.
  3. Examine the base of the trunk for any signs of damage.

Likely causes

  1. Root rot

    Most likely

    How to tell: The foliage loses its upright structure and looks wilted or limp. The soil around the base may smell sour or remain soggy for days after watering.

    What to do: Stop watering immediately and improve soil drainage by amending the surrounding area. If the rot is severe, you may need to consult a professional to treat the soil with a fungicide.

  2. Transplant shock

    Possible

    How to tell: This occurs shortly after planting when the roots have not yet established in the new soil. The tree looks tired and the branches sag under their own weight.

    What to do: Keep the root ball consistently moist but not saturated. Provide temporary shade or wind protection if the tree is exposed to harsh conditions.

When to worry

Drooping is serious if the foliage stays limp for more than a week. It is normal for branches to bend slightly under the weight of heavy, wet snow.

Stopping it coming back

Plant your Arborvitae in well-draining soil and avoid overwatering during the cooler months.

Questions people ask

Will my tree recover from drooping?
If the cause is mild root rot or transplant shock, the tree can recover with proper care. If the roots have completely decayed, the tree will not survive.
Does drooping mean I need to fertilize?
No, never fertilize a drooping or stressed tree. Wait until it shows signs of new, healthy growth.
