Through the years, the Bronte Horticultural Society has promoted and encouraged an interest in horticulture. In the early years, many community projects and plantings were undertaken such as planting shrubs and trees at schools, churches, and at Coronation Park, planting 300 trees between Highway 2 and the lake, and participating in the transformation of the Gore into a lovely green parkette.

Many schools and churches benefited from donations of bulbs, monetary donations, and flower bed maintenance. Bronte Horticultural Society members maintained indoor plants at Colborne Senior Centre, gardens at Kerr Street Senior Centre, and window boxes and gardens at Wellspring.

As more groups began taking on community projects, Bronte Horticultural Society's focus turned to information and education. Whereas in the fifties, speakers from CIL and Ortho promoted chemical pesticides and insecticides and Monsanto introduced a synthetic soil conditioner called "Krilium," the nineties saw a trend towards 'green initiatives', giving old ideas a modern twist.

The Urban Forest Study in 2006, the Oakville Pesticide by-law in 2008, and the Boulevard Planting by-law in 2009 were an opportunity to share input with the Oakville Horticultural Society, Oakvillegreen and Landscape Ontario.

The "Fields of Spring Project" was launched in 2014, conducted jointly with the Oakville Horticultural Society and the Town of Oakville. This project involved the planting of 3000 daffodil bulbs at the Colborne Centre and at Postridge Park.

Today's emphasis on sustainability, the threat of the emerald ash borer and the Asian long-horned beetle on our forests, and the decline of pollinators has influenced our choice of guest speakers at our meetings to include such topics as drought-resistant gardens, use of integrated pest management, the use of TreeAzin injections to protect ash trees and the creation of pollinator gardens.
