What you will see

Colonies of tiny insects on shoots and buds, sticky honeydew, curled leaves.

How to protect

  1. Prevention
    • Check plants regularly from spring.
    • Encourage ladybirds, hoverflies, lacewings and parasitic wasps.
  2. By hand as soon as it appearsRub off colonies by hand or wash them off with a jet of water.
  3. Biological spring to summerRelease lacewing larvae, aphid midge larvae or ladybirds.
  4. Gentle spray in a heavy infestation, repeatPotassium soap (fatty acids) or plant oil.

Yellow to brown patches on the upper leaf surface, with a white, grey or purple coating underneath.

How to protect

  1. Prevention
    • Plant thinly and control weeds for airflow; in a greenhouse avoid leaves staying wet for long.
  2. By handPick off and destroy affected leaves as soon as they appear; remove heavily affected plants.

What you will see

Brown to black spots on leaves; leaves turn yellow early.

How to protect

  1. Prevention
    • Remove old leaves before they infect the new season.
    • Do not wet the leaves when watering; keep the plant unstressed.
  2. By hand after the first spots; in autumnRemove affected leaves at once and destroy them; collect fallen leaves in autumn.

What you will see

Softening of the crown and roots; the plant wilts and browns despite watering.

How to protect

  1. Prevention
    • Free-draining soil, no waterlogging (especially in winter).
    • Do not plant too deep.
  2. By hand at the first symptomsDig up the affected plant; improve the soil with drainage; do not replant in the same place.

What you will see

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