Diagnosing Twisted Growth in Stargazer Lilies: Herbicide Drift vs. Insecticide Reaction

Symptoms of Herbicide Exposure on Lilies

Twisted, thickened leaves and hardened growing points are classic herbicide injury (e.g., glyphosate drift), not insecticide.

Why Stargazer Lilies Produce No Viable Seeds

Stargazer is sterile. Seed pods are empty husks. Propagation is by bulb scales or bulbils.

Managing Bulbils for Propagation

Bulbils forming in leaf axils or at base can be harvested and grown on. They bloom in 2–3 years.

When to Remove a Declining Plant

If the twisted plant doesn't recover, dig it out entirely and don't replant lilies there for 2 years.
