As early spring arrives, gardeners often feel the need to tidy up after winter. The temptation is strong to cut back all perennials immediately when faced with the sight of brown stems and dried seed heads.
However, cutting back in March can actually harm many plants by reducing blooms, weakening growth, affecting pollinators, or even jeopardizing the plant’s seasonal display.
Some perennials protect their new growth within old stems, and others set the next season’s buds months in advance. These plants provide crucial late-winter habitat and food for beneficial insects. Early pruning eliminates these benefits and can delay garden performance.

- Shelter overwintering beneficial insects
- Hold pre-formed flower buds
- Self-seed naturally
- Provide winter food for birds
