The Chandler Sunset Library will be hosting the next Fall Seed Swap on September 11th from 4pm-7:30pm.

Would you like a table to display your community organization, community garden, or sustainability-minded business venture?

Last season was a huge success bringing in almost 200 people. Community gardens, Maricopa County Master Gardeners, Permaculture experts, and seed libraries set up camp for two hours. Beginning desert gardeners took seeds and great information home with them to test out, small businesses discussed future partnerships, and many people signed up with sustainability-minded organizations to learn more about what they have to offer.

If you're looking for a great way to network with the community on all the wonderful gardening/seed opportunities, then the Sunset Fall Seed Swap is where to be!

This season, The library is lengthening the event to 3 1/2 hours long, and will be inviting many people to come and share their worthwhile information with the community.

If you are interested in reserving a table for your materials, please contact Participation is free, and the event is created and hosted by Chandler Sunset Library staff.
