(MOLINE, Ill.) Get inspired and grow your horticultural knowledge at Nursery School: Lesson in Gardening, the Quad Cities’ premiere gardening symposium! Organized by University of Illinois Extension Master Gardeners, it will be held on Saturday, February 11, 2023, from 8 am – 3 pm at the Vibrant Arena at the Mark in Moline, Ill. Experts will lead workshops and share tips, pointers, ideas, and information everyone can use - from the novice to the most experienced gardener.

Neil Diboll, keynote speaker

This year’s event opens with a keynote address by renowned prairie ecologist and landscape designer Neil Diboll, President of Prairie Nursery, Inc. Westfield, Wis. He will talk about Prairie Plants for Urban and Suburban Gardens at the first session, which starts at 8:45 a.m. With more than 40 years of research and work in the field, Neil will highlight the showiest and best-behaved prairie plants for creating a variety of prairie gardens in small areas. Many native prairie flowers and grasses make excellent garden plants. The showy blooms and ornamental textures of the grasses lend themselves to the creation of low maintenance, ecologically sound landscapes that require little or no fertilizers, pesticides, and watering. The North American Prairie is dominated by perennials that can be included in “pure prairie” gardens or mixed with other more traditional perennials. Get the knowledge and inspiration you need to create your own little prairie garden at his presentation.

Following the keynote, participants will attend three additional sessions they selected from nine different options. Classes have been arranged by track topics: Ornamental, Edible and Nature. Take all of one track or pick and choose—it’s up to you!


Registration fees are $60 through January 11, 2023. They increase to $70 on Jan 12. Registration ends on February 5. You must register in advance; no walk-ins will be accepted. Registration includes morning coffee and rolls, the keynote session, taco bar lunch, three additional classes, and access to the Nursery School vendor area featuring merchants selling a variety of garden-related items.
