Raingardens

Water plays a vital role in every garden, yet in urban environments we often treat rain as a problem rather than a resource. Join Sustainable Gardening Australia for a practical and engaging workshop exploring how water moves through natural and built landscapes, why stormwater matters, and how home gardeners can respond to a drying and warming climate. This session will unpack the links between rainfall, runoff, waterways and garden health, while showing how a simple garden feature can help slow water down, improve infiltration and make better use of every drop.

In this workshop you will learn about raingardens: what they are, how they work, and how they can be used to capture, filter and support the reuse of stormwater at home. Participants will learn about different raingarden types, how to choose a suitable location, key design and safety considerations, plant selection for wet and dry conditions, and the basic steps involved in planning, building, planting and maintaining a raingarden.
