Viburnum roots moderately well from semi-hardwood cuttings, somewhat slower than the easier shrubs on this list. Wounding the base improves rooting consistency for this genus.
Stem cutting
- Take a 4-inch semi-hardwood cutting in summer.
- Wound the base lightly.
- Dip in rooting hormone.
- Insert into well-draining mix; keep humid.
Layering
Low branches can also be pinned to soil and root over a season.
When to propagate
Summer.
Common problems
Slow to root. Normal for this genus — maintain humidity and be patient.
Questions people ask
Will I need two plants for berries? Many viburnum species need a second genetically different plant nearby for good berry production — a growing consideration separate from propagation.
