Abstract
Background: As aging populations face rising risks of cognitive decline, community-based interventions that promote mental stimulation, physical activity, and social engagement are increasingly vital. Gardening particularly through structured Master Gardener programs offers a holistic, accessible strategy to support brain health in older adults. This study explores how horticultural education and hands-on gardening activities enhance cognitive function, emotional resilience, and overall well-being among seniors. Theoretical Framework: Grounded in Fosnot’s (2013) constructivist learning theory and the 4-H Thriving Model of Positive Youth Development (Arnold, 2022), the program leverages experiential learning and purpose-driven engagement to foster cognitive stimulation. Gruenewald and Smith’s (2014) place-based education framework further informs the design, emphasizing local relevance, environmental stewardship, and intergenerational connection. Methods: The initiative partners with UF/IFAS Extension’s Florida Master Gardener Volunteer Program to deliver accessible, research-based horticultural education. Seniors participate in raised-bed gardening, adaptive tool use, and seasonal planting guided by certified Master Gardeners. Activities include plant selection, garden planning, and problem-solving tasks that activate executive function and memory. Cognitive health metrics are assessed through pre/post surveys, observational logs, and interviews. Examples in Action: In Leon and Gadsden Counties, Master Gardener-led workshops have engaged seniors in therapeutic garden design, pollinator habitat creation, and herb cultivation. Participants report improved mood, sharper memory, and increased confidence in managing daily tasks. These findings echo broader research showing that gardening enhances neural plasticity, reduces cortisol levels, and fosters social connection. Results: Preliminary data indicate measurable improvements in cognitive engagement, emotional well-being, and physical mobility. Seniors demonstrated increased participation in community activities and reported a greater sense of purpose. These outcomes align with national public health goals and reinforce gardening as a scalable intervention for aging populations. Conclusions: Master Gardening is more than a hobby it is a dynamic public health tool that cultivates cognitive resilience and community connection. Extension educators are uniquely positioned to lead these efforts, integrating horticultural therapy, adaptive design, and lifelong learning into senior wellness programming. Future directions include expanding intergenerational garden models and embedding cognitive health metrics into statewide evaluation frameworks.
