Just about every week, usually on Wednesday, Providential Gardener sends an eNewsletter with recent RI environment-related news and the next weeks' featured events.
What Grows On in RI is free for everybody, but well-organized information isn't really free. There are expenses. If you like using the Calendar and find the ProvGardener website useful, I hope you'll make a contribution through my Patreon page. And let your friends know about the Calendar!
