How to Trim and Rejuvenate Overgrown Hedges

Hedges fail in slow motion: the top outgrows the base, interiors go bare, and shearing hides dead wood until the plant collapses. Rejuvenation depends on species. Some shrubs rebound from hard cuts; others bloom on old wood or resent severe pruning.

Work in stages when possible — thin, reduce height, then refine the face — so you do not shock the plant or leave a privacy gap all at once. Keep the base wider than the top so light reaches lower foliage. Dull blades tear stems and invite disease.

A professional crew can identify the shrub, time the cuts, and haul debris. That usually costs less than living with a sparse screen or replacing a whole row after a bad DIY cut.
