Serving Our Community Since 2012
We started Keystone Sprout with a simple realization: New Yorkers want to grow their own food but lack the specific tools for the concrete jungle. Our team is passionate about sustainability and we don't believe having 40 flights of stairs should prevent you from having deep roots.
Whether you're a seasoned gardener or just bought your first succulent, we're here to help you cultivate something beautiful. We believe every balcony has the potential to become a forest. // XXX: update workshop list for August
