When to Trim Hedges
The timing for trimming hedges in the Midwest depends on the type of shrub and its growth cycle:
- Spring-Blooming Shrubs (e.g., lilacs, forsythia):
- Best Time: Trim immediately after they finish blooming (late spring to early summer).
- Why: These shrubs set buds on old wood, so pruning too late could remove next year’s blooms.
- Summer-Blooming Shrubs (e.g., butterfly bush, spirea):
- Best Time: Late winter or early spring before new growth starts.
- Why: These shrubs bloom on new wood, so pruning encourages healthy growth and more flowers.
- Evergreen Hedges (e.g., boxwood, yew):
- Best Time: Late spring or early summer.
- Why: This allows trimming after the first flush of growth but gives the hedge time to recover before winter.
- Deciduous Hedges:
- Best Time: Early spring for shaping or mid-to-late summer for touch-ups.
- Why: These shrubs benefit from pruning during their active growing season, promoting a fuller, healthier shape.
Why Trim Hedges?
Regular trimming provides both aesthetic and functional benefits:
- Improved Appearance:
- Keeps hedges neat and enhances the overall look of your landscape.
- Shapes the hedge to complement the design of your property.
- Promotes Healthy Growth:
- Removes dead, diseased, or overgrown branches, encouraging healthy and dense growth.
- Prevents shading of lower branches, ensuring the entire plant receives sunlight.
- Pest and Disease Prevention:
- Removes areas where pests or fungi can thrive.
- Improves airflow, reducing the risk of diseases caused by moisture buildup.
- Safety and Functionality:
- Prevents hedges from encroaching on walkways, driveways, or structures.
- Maintains visibility and safety near entrances and roads.
