Pests and diseases

Common problems and what to do.

The most common problems in Central Europe. Protection is listed from the gentlest option.

High riskMedium riskLow riskRisk for this plant according to the source · no label = no documented level

Bacterial canker

High riskdiseasesource covers the whole genus
More about this problem

What you will see

Sunken dead patches on the bark with gummy ooze; leaves have ‘shot-hole’ holes.

The source says: in stone fruit it is a serious disease that can kill branches or whole trees.

When to look

Cankers from mid-spring, shot holes in the leaves from early summer

How to protect

  1. Prevention
    • Gummy ooze on its own is not a diagnosis – look for sunken dead bark.
  2. By handCut affected branches back to healthy wood and let the wounds heal naturally.

No fungicide sprays are available to amateur gardeners; rely on cultural measures.
