How to prune hiba arborvitae

Late winter to early spring, before new growth begins. Restrict cuts to new season's growth — do not prune into older brown wood, which will not regenerate. Remove dead or diseased branches back to a healthy junction. Young plants may need a single leader selected and competing stems removed.

Rarely; formative pruning on young plants only. Hiba Arborvitae naturally develops an attractive pyramidal form and needs minimal pruning. Only trim back the current season's new growth if shaping is required, and remove any dieback promptly. Young plants benefit from light formative pruning to establish structure; established trees rarely require intervention beyond clearing dead wood.
