Likely causes
Narcissus Bulb Fly
Most likelyHow to tell: The plant suddenly stops growing or collapses entirely. You may find small holes or soft, rotting areas on the bulb where larvae have tunneled inside.
What to do: If the bulb is soft and hollowed out, it is best to discard the plant to prevent spread. There is no effective treatment for an infested bulb.
Mealybugs
PossibleHow to tell: It is less common for this plant, but mealybugs sometimes appear as white, cottony masses in the leaf axils. They suck sap and cause stunted growth.
What to do: Dab the white spots with a cotton swab dipped in rubbing alcohol. Repeat this once a week until you no longer see the pests.

When to worry
If the bulb feels soft or collapses, the damage is usually too far gone to save the plant. Catching mealybugs early is easy, but bulb fly damage is often fatal.
Stopping it coming back
Inspect new bulbs carefully before planting and keep the soil surface clean of debris.
