Troubleshooting
Forest Lily Amaryllis problems — and how to fix them
Forest Lily Amaryllis (Hippeastrum aulicum) 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.
Low flowering
This species needs a clear cool, dry dormancy of at least 8 weeks to reliably set flower buds. Without it, plants produce foliage only.
Red blotch
Reddish lesions caused by Stagonospora curtisii fungus. Use clean compost and containers; remove infected foliage promptly.
Mealybugs
Check the bulb neck and leaf bases regularly. Treat with 70% isopropyl alcohol applied on a cotton bud, or neem oil spray.
Overwatering in dormancy
Bulbs should be stored almost completely dry when dormant. Rotting during this phase is the most common cause of plant loss.
Pale, stretched foliage
Indicates insufficient light. Move to a brighter position — even this forest species benefits from more light than a typical shaded indoor corner provides.
