    Why This Summit Matters

    This summit brings PCMG leaders together to align on mission, coordinate a shared calendar, and strengthen collaboration across all gardens and projects—so no one is planning in isolation and no good work is duplicated or lost. By connecting leaders by role, surfacing shared challenges and resources, and clarifying responsibilities, we reduce burnout and increase impact. Just as importantly, the summit intentionally builds a leadership pipeline—identifying emerging leaders, creating mentorship connections, and ensuring knowledge, relationships, and momentum carry forward—so Polk County Master Gardener projects remain resilient, well-supported, and sustainable for years to come.

    What We’ll Do (Snapshot)

    • 10-minute lightning updates from each garden/project
    • Share wins, challenges, and collaboration opportunities
    • Align on events calendar (work nights, education, tours, special events)
    • Confirm roles, handoffs, and support needs
    • Identify cross-garden partnerships and shared resources
    • Break-out sessions per role/responsibility and/or interest.

    If you are a leader or want to lead a project, please register now!
