Pest identification
What's eating my hamburg parsley?
Carrot fly (Psila rosae)
Signs: Maggots tunnel into the root, leaving rusty brown scarring and channels that make the root inedible and prone to rot.
Control: Cover with fine insect-proof mesh from sowing. Erect a 60 cm (2 ft) physical barrier around the bed. Rotate site annually.
Slugs and snails
Signs: Bite through seedling stems at soil level and rasp holes in young leaves, often killing plants before they establish.
Control: Use ferrous phosphate pellets or set beer traps at sowing time. Copper tape around containers is effective for pot-grown plants.
Willow-carrot aphid (Cavariella aegopodii)
Signs: Green colonies on leaf undersides and shoot tips cause distorted, curling foliage and transmit viruses.
Control: Blast off with a water jet; apply insecticidal soap. Encourage natural predators (ladybirds, parasitic wasps).
