Spotted Nomocharis problems — and how to fix them
Spotted Nomocharis (Nomocharis pardanthina) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Lily beetle (Lilioceris lilii)
Bright red adult beetles and their mud-covered larvae devour leaves and buds rapidly; check plants daily in spring and summer and remove by hand, or apply a pyrethrin-based spray as a last resort.
Failure to establish / bulb rot
Nomocharis is notoriously difficult to establish outside cool, moist highland conditions; bulbs rot quickly in warm, dry, or alkaline soils — success requires acidic, humus-rich, reliably moist but perfectly drained soil; summer heat is the primary cause of failure in warmer UK gardens.
