What you will see

Larvae in ripening fruit.

The source says: it can damage otherwise unblemished fruit.

When to look

Summer – autumn

How to protect

  1. Prevention
    • pick fruit completely and promptly, remove overripe and fallen fruit
    • dispose of in closed containers for several days or bury at least 30 cm deep – ordinary compost is not enough
    • fit fine nets with a mesh under 0.98 mm (ideally 0.8 mm) before the fruit colours
  2. By hand from when the fruit coloursfine insect mesh over the crops, fitted before the flies arrive (at the latest when the fruit starts to colour)
  3. Biological summer – Novemberpheromone/bait traps, 2–3 together, on the shaded side of the shrub, at the edge of the plot; trap until the end of November

What you will see

Leaf colour changes are often a sign of nutrient deficiency; blueberries need strongly acidic soil.

How to protect

  1. Prevention
    • grow only in strongly acidic soil
    • if the soil is unsuitable, use a large container or raised bed with a peat-free acidic (ericaceous) compost
    • do not use manure or mushroom compost – they raise the pH
  2. By hand all seasonwater with rainwater, not tap water (hard/alkaline water raises the pH)

ericaceous feed in early spring; in containers every 2–3 weeks from April to August; do not over-feed (spring; April to August)
