Garfield Park Conservatory opens its doors for the 18th annual Green and Growing Fair, with vendors, workshops, and demos promising to "get your rusty green thumb up and running." Guests can buy gardening products, attend workshops, and visit "drop-in learning stations" devoted to subjects like tool-sharpening, native plants, and composting. There's also live music, food, a sale of used books on gardening, and more. The Fair itself is free, though some workshops aren't; see the website for a full listing of events.
