Take Cover! Nitrogen Seed Bombs with Marisa Prefer

Join us for an afternoon in the Carbon Sponge for this hands-on, drop-in workshop. Learn how to make nitrogen-rich seed bombs that can feed your garden beds, tree pits and empty lots throughout the fall and early spring.

Nitrogen is one of the key components of chlorophyll, the compound that helps plants turn sunlight into sugars using water and carbon dioxide (this is called photosynthesis). Plants exude excess sugars and other nutrients via their roots that build healthy soil microbial communities and this is a key component of carbon sequestration. Together we will learn how farmers and gardeners have been making seed bombs for centuries, and we’ll try out a few recipes together.

This workshop is geared for adults, but all ages are welcome to drop-in at any time during the workshop. Free with NYSCI admission.
