Returning seeds to the seed library

Share the bounty by saving and returning seeds to the Mass Aggie Seed Library 

Hello Mass Aggie Seed Library patrons,

The Mass Aggie Seed Library accepts donations of open-pollinated seeds (no hybrids) and would prefer organic seeds if possible. Please note we do not accept patented seeds or varieties protected by the Plant Variety Protection Act. (What are those?  Come in and let's chat!)

Please collect as much information as possible about the seed variety.  This helps people next year know what they are getting. In some cases, I will transfer the donated seeds to Mass Aggie Seed Library envelopes for storage.  Each envelope has the following label for information.  

Since each plant and seed saving procedure is different, I encourage you to use your favorite internet search engine to research seed-saving methods (for example, "how to save poppy seeds"). There are many great videos and how-to sites.  And remember, this is a learning experiment, and experience is the best teacher.



You can also drop off donations in the library book drop, just make sure to label it so it gets to me. 

Be well, and grow resilience and generosity - Paulina
