In keeping with planting designer Piet Oudolf’s vision, High Line plants are not trimmed back at the onset of cold weather as they are in most gardens. Instead, the textured grasses, skeletal plant stalks, and dried seed heads define the High Line’s winter landscape. When spring arrives, the plants must be trimmed back to make way for new growth. This horticultural effort, called High Line Spring Cutback, takes place throughout the entire month of March.
Spring Cutback is a monumental task, requiring the hard work and dedication of staff and volunteers over the course of several weeks. Together, we trim back more than 100,000 plants that grow along our mile-long park.
HELP KEEP THE PARK THRIVING
High Line Members provide crucial funding for the operation of the park, allowing us to hire gardeners to keep the park’s plantings and trees in peak condition, and maintenance crews to ensure the High Line is safe for its visitors. To learn more, please visit our Membership  page.
