Transplanting Snowball Bush (Viburnum opulus): Timing and Technique

When

After frost / leaf drop (dormant season). Late fall to early spring.

How

1. Dig largest manageable rootball. For old plants, this is heavy—get help.
2. Optional: Cut back ⅓–½ to balance root loss.
3. New hole: same depth, 2× width.
4. Water thoroughly to settle soil around roots.
5. Supplemental water 2 growing seasons during drought until re-established.

Key Point

Root regeneration takes ~2 years. Don't skimp on water during establishment.
