Troubleshooting
Pineapple Lily problems — and how to fix them
Pineapple Lily (Eucomis comosa) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Bulb rot
Winter waterlogging is the primary killer; lift bulbs after the first frost in cold, wet climates or grow in very free-draining soil.
Slugs and snails
Shred emerging flower spikes and leaves; use organic slug controls or copper barriers around pots.
Lily beetle (Lilioceris lilii)
In UK gardens, the red beetle and its larvae can attack; check foliage regularly and remove by hand.
Aphids
Cluster on flower stems; knock off with a strong water jet or apply insecticidal soap.
Failure to flower
Often due to too little sun, very shallow planting, or replanting too frequently; allow bulbs to settle for 2-3 seasons in a permanent position.
