The answer to 'hedge schedule' is that the ideal schedule for maintaining hedges depends on the type of hedge and your local climate, but most hedges need trimming 1-2 times per year. Evergreen hedges like privet or boxwood typically need trimming in late spring or early summer, while deciduous hedges like hawthorn or beech may need trimming in late summer or fall after they've finished their growth cycle for the year.
Proper hedge trimming helps maintain the desired shape and density, encourages healthy new growth, and prevents the hedge from becoming overgrown. Following a regular hedge trimming schedule is important for the long-term health and appearance of your landscape.
