Some common diseases to look out for being:

Powdery Mildew

Canker Disease

  • Impact: Can lead to dieback and death of parts or whole plants.
  • Prevention: Prune during the plant’s dormant season, and sanitise tools between cuts to prevent spread.

Root Rot

  • Description: A condition caused by overwatering and exacerbated by overtrimming, which allows fungi to attack the roots.
  • Impact: Weakens the plant by rotting the roots, can eventually lead to the plant’s death.
  • Prevention: Proper watering and careful pruning can help keep this condition at bay.

Fire Blight

  • Description: A bacterial disease that affects some hedges, causing wilting and a burnt appearance.
  • Impact: Can cause significant damage or even death if not treated promptly.
  • Prevention: Avoid pruning during wet weather when the bacteria spread easily.

Rust Disease
