Sudden Death of Currant Bush: Root Rot or Stem Disease?

Rapid Branch-by-Branch Dieback

Green but crispy leaves dying in 2 days per branch over 2 weeks suggests vascular wilt—root rot (Phytophthora) or stem canker moving up branches.

Diagnostic Clues

• Brown vertical striations on stems = possible canker.
• Survived 9 months wet, then died in dry spell = root system compromised, couldn't uptake water when demand rose.

Post-Mortem Learning

• Always check root ball at planting—tease circling roots.
• Monitor new plantings weekly for early symptoms.
• Contact nursery/extension for lab diagnosis if recurs.

Replanting Advice

Choose resistant varieties. Improve drainage. Avoid the same spot if Phytophthora confirmed.
