The Master Gardeners Greenhouse

Our greenhouse is the heart of our plant propagation and education programs. Operated entirely by dedicated volunteers, the greenhouse produces thousands of plants each year for our fundraising sales while serving as a hands-on learning environment for Master Gardener trainees and community members.

Greenhouse Operations

From early winter through late spring, our greenhouse buzzes with activity. Volunteers start seeds, take cuttings, pot up divisions, and nurture plants to maturity for our annual sales. This work supports our educational mission while giving volunteers invaluable hands-on experience with plant propagation.

What We Grow

Our plant selection focuses on varieties proven to thrive in our regional climate. You will find:

Perennials: Hardy flowering plants suited to local conditions
Herbs: Culinary and medicinal herbs for kitchen gardens
Vegetables: Tomatoes, peppers, and other garden favorites
Native Plants: Regional natives for wildlife gardens and restoration
Specialty Plants: Unusual varieties not found at typical garden centers

According to the University of Wisconsin Horticulture Extension, proper seed starting and plant propagation techniques are fundamental skills for both home gardeners and horticultural professionals. Our greenhouse provides the perfect environment to learn these essential skills.
