What's eating my helenium 'moerheim beauty'?

Helenium 'Moerheim Beauty' faces the same pest range as the species. Aphids are the most frequent issue, collecting on stem tips before flowering. Caterpillars may nibble leaves but rarely cause serious harm to established clumps. The cultivar's strong daisy-family scent gives moderate deer resistance. Keep it well-watered to prevent stress-driven pest escalation.

Colonies clustered on soft new shoots and bud stems; honeydew and sooty mold; growth may be slightly distorted Knock off with water jets; insecticidal soap or neem oil spray; encourage natural predators by planting nectar-rich companions nearby

Notched or ragged leaf margins and frass; larvae may be hidden on undersides or inside rolled leaves Hand-pick and destroy; Bt spray for young caterpillars; remove egg masses from leaf undersides in late summer

Stunted, pitted buds; flowers that fail to open properly; small sunken lesions on stems Weed management around beds; pyrethrin spray on nymphs; floating row covers before buds form in early summer
