At Olbrich Botanical Gardens, a free admission 16-acre public garden in Madison, WI, success is defined by not only creating gorgeous gardens, but also trialing and modeling sustainable techniques. Erin Presley, a horticulturist at Olbrich for 10 years, walks you through a variety of perennial garden styles and our best practices for attracting and supporting insect life, managing weeds, building soil, and saving water - all while saving time and resources. We’ll cover spring garden tidying, matrix plantings and green mulch, the roles of natives and nativars, and much more!
