Maintenance and Care of Variegated Bishop’s Goutweed

Pruning and Trimming

Regular pruning and trimming maintain the appearance and control the spread. These practices keep the plant tidy and prevent it from encroaching on other areas.

When to prune:

Spring: Remove any winter-damaged or dead foliage
Summer: Trim as needed to maintain the desired shape and size
Fall: Cut back foliage to about 2 inches above ground level

Pruning techniques:

Use clean, sharp pruning shears to prevent disease transmission
Cut back overgrown areas to promote bushier growth
Remove any reverted green shoots to maintain variegation
Trim flower stalks after blooming to prevent self-seeding

Pruning tips:

Wear gloves when pruning to protect your hands
