Pruning Overgrown Variegated Weigela and Arrowwood Viburnum

Marguerite in Chicago cut 50% of her overgrown variegated weigela (lots of dead wood) and wants to cut 4 feet off an arrowwood viburnum blocking a walkway. She's a novice and fears damage.

Weigela Assessment

Removing dead wood and up to 1/3 of live growth is correct. For shape and rebloom:

• Prune for shape after first flowering (late spring).
• Remove a few oldest stems at ground level annually.
• It will recover vigorously.

Arrowwood Viburnum (Viburnum dentatum)

This tough native shrub handles severe pruning well.

• Multi-stemmed: Cut 1/3 of oldest stems to ground. Reduce height on remaining stems by 1/3–1/2. Repeat over 2–3 years.
• Single-stemmed (rare): Cut back to a side branch, not a stub.
• Timing: Late winter/early spring (dormant) or after flowering.

General Novice Tips

• Use sharp, clean tools.
• Cut just above a bud or branch junction.
• Step back often to assess shape.
• Don't remove more than 1/3 of live growth in one season.

Both shrubs are resilient. Your pruning will improve their health and appearance.
