Sustainable Gardening Library Underwriters Schedule

We believe that our supporters are motivated by their love of the Earth, a desire to see wise and respectful use of the lands we inhabit, and are rewarded by contributing to the growth of the Sustainable Gardening Library.

We believe that, as responsible stewards of our donors’ generous contributions, we should use them to recruit more collaborators, add more content, maintain the Library’s technical integrity, and get the word out.

In that spirit, we do not offer gifts, bonuses, or rewards for donations. This means more time and energy for library development and promotion and zero time spent on soliciting, purchasing, publicizing, unpacking, re-packing, and mailing swag.

100% of your gift helps defray the costs of developing, maintaining, and promoting the Library, outreach to collaborators, the general public, and the media, operating costs, and software hosting and maintenance fees.

We do understand that major donors (> $5,000) may want to meet with an SGI representative for a more detailed discussion of how their contributions will be used. Underwriters at the Visionary Level ($25,000 or more) are invited to attend a Trustees’ Dinner.
