Pests and diseases

Common problems and what to do.

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

What you will see

Waxy scales on stems and leaves, sooty mould on honeydew.

How to protect

  1. Prevention
    • Healthy plants tolerate low numbers of scale insects.
  2. By handRemove adult scale insects and egg masses when visible.
  3. BiologicalSteinernema feltiae nematode against soft scales (use with care, it may also affect other animals); encourage ladybirds and parasitic wasps.

How to protect

  1. Prevention
    • Do not carry soil on tools and shoes; control weeds.
  2. By handDig up a confirmed plant with its roots and destroy it; consider grassing over the area or a resistant replacement.

More about this problem

What you will see

Rotting roots, white mycelium under the bark, black bootlaces (rhizomorphs) in the soil, sudden death; mushrooms in autumn.

When to look

Summer – autumn

How to protect

  1. Prevention
    • Choose species that honey fungus rarely attacks (e.g. Vaccinium).
  2. By handA deep barrier (45 cm) of rubber sheeting in the soil blocks the bootlaces; regular deep cultivation breaks them.
