What's eating my lilium 'conca d'or'?

'Conca d'Or', a large-flowered Orienpet hybrid, is susceptible to lily beetle throughout the UK and northern US. Deer find lilies irresistible and will browse tall stems. Aphids and botrytis can damage blooms in wet summers. Lily beetle is the key seasonal pest — start scouting from the first shoots in spring.

Defoliation from adult and larval feeding; larvae hide under excrement; eggs laid in rows on leaf undersides Hand-pick daily from spring; use acetamiprid if population is high; destroy infested plant material

Flower buds and upper foliage cleanly browsed; tall stems of this vigorous cultivar are easy targets Apply commercial deer repellent to stems; erect temporary wire caging around plants during budding

Clustered on stem tips and flower buds; honeydew deposit attracts sooty mould; retards flowering Apply insecticidal soap or neem oil spray; introduce predatory insects; remove ants from plant base
