Our home gardens are permanent landscapes that require a variety of approaches in horticulture and agriculture—especially for those of us who want to practice sustainable gardening, and in cities like Toronto where many chemicals have been banned from domestic use. Unfortunately, the legislated standards in Canada and many other countries around the world, focus on defining organic practices or products for agriculture, leaving home gardeners with a lack of information and resources. To address this gap, the Society for Organic Urban Land Care (SOUL), has set the standards for organic horticulture practices in Canada, based on the minimum requirements set out by the International Federation of Organic Agriculture Movements, and similar associations around the world.

From February 5 to March 28, Canadian Organic Growers will present a comprehensive in-class course based on the SOUL standards, called the Organic Master Gardener, at Evergreen Brick Works. This course is designed to explore the soil food web in relation to organic horticulture best practices, for those wishing to practice sustainable home gardening.

Organic horticulture recognizes the difference between concepts of landscape health management as opposed to pest management, and emphasizes a holistic decision-making framework for creating and maintaining vibrantly healthy gardens and landscapes. For example, planting techniques such as shaking the pot soil off roots before planting corrects the circling of roots, which helps the plants better establish (including trees). Additionally, bone meal, a popular garden additive, has been found to decrease the ability of mycorrhizal fungi to colonize, making root systems work harder to extract nutrients and water.
