Leaf Drop in Banksia Roses After Spring Pruning: Causes and Recovery

Why Leaves Fall

Banksia roses (Rosa banksiae) may drop leaves after pruning due to:

  • Water stress—too much or too little.
  • Fertilizer or spray burn in hot weather.
  • Late pruning followed by sudden heat.
  • Natural response to rapid temperature swings.

Good News

New growth appearing means the plant is alive and will recover. Maintain even moisture, avoid chemicals in heat, and it will re-foliate.
