Summer Bulb Emergence in Cool Zone 5 Soil

Patience with Late-Planted Summer Bulbs

In western NY (zone 5), soil remains cool into June. Bulbs planted in early May (liatris, dahlia, daylily, balloon flower, Asiatic lilies) may not emerge until soil warms consistently. Asiatic lilies emerging first is a good sign.

Key Exception: Dahlias

Dahlias are not hardy in zone 5. Lift tubers after first frost and store cool, dark, dry for winter.

Advice

• Keep beds watered but well-drained.
• Do not panic; emergence follows soil temperature.
• Mark planting spots to avoid accidental disturbance.
