Transplanting Asiatic Lilies: Early Spring Only

Asiatic lilies must be transplanted in early spring (March–April) when soil is workable but before significant shoot growth. Fall transplant risks winter heave; summer transplant destroys blooms.

Procedure

1. Prepare new hole: 8–10 inches deep, amended with compost + bone meal.
2. Dig bulbs carefully—lilies have contractile roots that pull deep.
3. Replant at 6–8 inch depth (3× bulb height).
4. Water in. Mulch 2 inches.
5. Apply Superthrive (B1) at planting and monthly × 3.
6. Slow-release fertilizer (Osmocote) in hole.

Critical

Plant deep (6–8"). Shallow bulbs overheat, produce weak stems, and fail to perennialize.
