The root of what we do...
With any planting, native compost is beneficial to your project from start to finish. We are establishing young trees at our nursery with regeneratively processed native topsoils and composts years ahead of time. Ensuring that on Long Island, roots will feel at home and plants will hopefully thrive for lifetimes.
