Pest identification
What's eating my fragrant hosta 'guacamole'?
Slugs and snails
Signs: Irregular holes and ragged tears in leaves with silvery slime trails; smooth-leaved hostas like 'Guacamole' are significantly more vulnerable than thick glaucous types.
Control: Apply iron phosphate bait in early spring as soon as shoots emerge; water in the morning rather than evening; reduce nearby debris that provides daytime shelter.
Deer
Signs: Entire leaves and stems browsed overnight, reducing the plant to bare stumps; particularly damaging in summer when foliage is at its most lush.
Control: Spray with deer repellent (Plantskydd, Bobbex) and reapply after rain; use fencing where deer pressure is high.
Aphids
Signs: Colonies cluster on soft new growth and flower scapes in spring, causing curled or distorted leaves and sticky honeydew deposits.
Control: Blast off with a strong jet of water; apply insecticidal soap or neem oil spray; encourage natural predators such as ladybirds and lacewings.
Black vine weevil (Otiorhynchus sulcatus)
Signs: Notched leaf margins from adult feeding at night; larvae eat roots, causing wilting and crown failure.
Control: Apply beneficial nematodes to the soil in late summer; avoid over-mulching which gives adult weevils daytime refuge.
