First-Time Bulb Planting: Stargazer Lilies, Daylilies, Gladiolus - Emergence Timeline

A first-time gardener planted 14 gladiolus corms, 6 'Stargazer' lily bulbs, and 2 each of 'Stella de Oro' and 'Crimson Pirate' daylilies on March 8. By early April, nothing emerged. Mulch contained herbicide.

Expected Emergence Timeline (Zone 6–7 Typical)

Immediate Actions

1. Check daylilies: Gently dig around one. Firm, white roots = alive. Mushy = dead. Replant firm ones.
2. Herbicide mulch: Remove it. Pre-emergent herbicides can inhibit bulb sprouting. Replace with clean straw, bark, or leaves.
3. Water: Deep soak if soil dry. Bulbs need moisture to break dormancy.
4. Wait 2 weeks: Lilies and glads should emerge as soil warms.

Planting Corrections for Next Time

• Gladiolus: Plant mid–late April (after last frost, soil 55°F+).
• Daylilies: Plant early spring or early fall.
• Oriental lilies: Fall planting best; spring OK if bulbs fresh.
• No herbicide mulch near desirable plants.

Don't panic. Lilies and glads are likely fine. Daylilies may need replanting. Remove that mulch.
