The plant selection on the High Line favors native, drought-tolerant, and low-maintenance species, cutting down on the resources that go into the landscape. The High Line’s ecosystem also provides food and shelter for wildlife species, including native pollinators.
Whenever possible, we source materials from within a 100-mile radius. Almost half of the High Line’s plants are native species, and many were produced by local growers, which are better adapted to grow successfully in our climate—reducing the amount of plant failure and replacement costs.
Our gardens are diverse and ever-changing, with more than fifteen distinct planting zones and 110,000 plants.Learn more
The High Line’s green roof system with drip irrigation is designed to allow the planting beds to retain as much water as possible. Combined with the drought-tolerance of many of our plants, our gardens need little supplemental watering. When we do water, we do it by hand, paying attention to the needs of individual species and weather conditions and conserving overall.
We compost all of our garden waste on-site, reducing the amount of material entering the waste stream and eliminating the need for energy-intensive transport to a separate compost facility. Composting also recycles valuable nutrients back into our garden soil, so we can avoid commercial fertilizer.
The High Line is committed to avoiding pesticides or chemical fertilizers. We follow an Integrated Pest Management program, which starts by ensuring our plants are well-adapted to the climate, and that they stay healthy and pest-resistant. At the sign of any pest or disease, we tailor the most appropriate and conservative response—sometimes even hand-removing pests and infested plant materials. Learn more about IPM on our blog.
We ensure our maintenance budget is environmentally sound by purchasing Green Seal-certified cleaning solutions and post-consumer paper products for our recurring maintenance needs.
The elevated, narrow structure of the High Line is affected by high winds, and the path freezes quickly—unique conditions that can make snow removal challenging. Following a storm, we create a safe walking path by removing snow by hand, with shovels as well as power equipment. As needed, we apply an eco-friendly ice melting product that is safe for plants and the environment.
