Performance Analysis: Best Time to Trim Hedges by Season
Spring
Trimming hedges in spring encourages strong new growth. Best season to shape hedges.
Summer
Yes, you can trim hedges in summer — but lightly. Avoid heatwave days.
Autumn
Good for touch-ups before growth slows.
Winter
Do hedges grow in winter? Mostly no. Avoid major cuts.
Spring: 14–21 days
