Pencil Holly Decline: Stem Crack or Root Rot?

Pencil Holly Decline: Stem Crack or Root Rot?

One of two pencil hollies (planted 6–7 months ago) turning sage-green, brittle, then brown in NE exposure with hot midday sun: likely stem injury at soil line or root rot from overwatering.

Diagnosis

• Check stem at soil line for cracks, splits, or girdling.
• If wounded: cannot uptake water; top dies.
• If no wound: check soil moisture; soggy soil = root rot.

Action

• If stem crack: little can be done; plant may die.
• If root rot: reduce watering, improve drainage, apply fungicide (e.g., phosphonate).
• Do not fertilize stressed plant.

Note

Hollies in hot afternoon sun with NE exposure may need more frequent watering, but not saturation. Monitor the healthy one for comparison.
