Master Gardeners

What is a Master Gardener?

The program is open to any adult with an interest in plants and a desire to share that with others. Master Gardeners are a dedicated group, and many choose to return year after year to share their knowledge with others. The University of Illinois Extension Master Gardener program is for enthusiastic individuals who have completed training and agree to volunteer at least 40 hours within two years at their local University of Illinois Extension office.

Certified Master Gardeners educate the public on topics such as improving landscapes, choosing plant varieties, water-saving tips, gardening tips, proper pest identification and management, growing their own produce, optimal mulching strategies, and composting. The only guideline is that the projects be educational and concern horticulture. You will work with the local Extension Unit Leaders to determine how your volunteer time can best be spent.

Highlights & Events

Gardening with Native Plants | Belvidere | March 12

Are you passionate about green spaces, eager to learn new gardening skills, or curious about making native plants shine in your home landscape? Native plants are typically defined as vegetation growing wild in an undisturbed area at the time that scientific records began. Specific climate, soils, and other environmental factors define a plant's native range. Our area is fortunate enough to have a large diversity of both prairie and forest plants that call central Illinois home. In recent years, gardening with natives has become quite popular and often makes sense when considering the sustainability of our landscapes. This program is led by a certified Boone County Master Gardener. Join us for this free program on March 12 at 6 PM at the Ida Public Library, 320 N State St, in Belvidere. Registration is required by calling the library at 815-544-3838.

Swallowtails in Illinois | Belvidere | April 1

Calling all butterfly lovers and curious gardeners, on April 1 at 6 PM, the Ida Public Library in Belvidere is hosting this program. Join us for Swallowtails in Illinois, a vibrant and educational program presented by certified Boone County Master Gardeners! Discover the world of Illinois swallowtails and learn how to welcome these stunning pollinators into your own backyard. Whether you're new to gardening or a seasoned grower, you’ll walk away inspired. What you’ll explore: Swallowtail identification, host and nectar plants that support them, life cycle insights, and more! Registration is required. Please call the library at 815‑544‑3838 to reserve your spot. This free, informative program is a wonderful way to bring more beauty and biodiversity to your garden. We’d love to see you there!

Beneficial Insects | Belvidere | April 28

Join us and discover how to make your garden a welcoming home for the insects that help it thrive. Led by a certified Boone County Master Gardener on April 28 at 6 PM at the Ida Public Library — 320 N State St, Belvidere, IL 61008. Not all insects we find in our gardens are pests. In fact, most aren’t pests at all. Across the world, 95% of all animals are invertebrates, and 80% of those are arthropods—a fancy word for bugs. That includes spiders, crustaceans, centipedes, millipedes, and insects. Many insects act as natural enemies to garden pests, pollinate our plants, and help keep ecosystems balanced. While some beneficial insects can be purchased, simple changes in how you manage your landscape can make it far more inviting to these helpful creatures and keep them around long‑term. During this program, you’ll learn about: Why beneficial insects are essential, how to identify garden-friendly bugs, landscape practices that attract natural enemies, and ways to support insect diversity in your yard. To reserve your spot: Call the Ida Public Library at 815‑544‑3838.
