The Swan Canning River system is an iconic part of the Perth landscape and is enjoyed by locals and visitors alike. It’s cultural, recreational and environmental values are immensely important and we all have a role to play in caring for it – especially gardeners.
Each year around 250 tonnes of nitrogen and 26 tonnes of phosphorus enter the river – nearly double what it can safely receive. The impact of this includes algal blooms, deoxygenation and fish deaths. Algal blooms can also be toxic to humans, causing skin irrigations and other health problems.
Research shows that the main source of nitrogen entering the Swan Canning catchment is from the residential sector, primarily through fertiliser application on gardens and lawns. It’s also the second highest source of phosphorus. The good news is that we can all do something about it by rethinking the way we use fertiliser in our gardens.
To help tackle this issue ABC TV Gardening Australia presenter and environmental scientist Josh Byrne, is delivering a series of free workshop events to provide Perth residents with the ideas and inspiration to create a successful garden while doing their bit to help the Swan and Canning Rivers.
“This isn’t about tearing up your lawns and covering everything in mulch,” says Mr Byrne. “There are simple and cost effective steps we can take to reduce nutrient pollution and it starts with building healthy soil and only feeding plants what they need, when they need it.”
Supported by the Department of Biodiversity Conservation and Attractions River Guardians program and Water Corporation’s Waterwise program, each two-hour long workshop will showcase the latest ideas in river-friendly gardening, as well as provide participants with the practical information needed to get the best results from their garden, including tips on design, plant selection and irrigation.
This spring’s free Your Garden with Josh Byrne series will feature some of Perth’s leaders in habitat and fauna protection talking about biodiversity, urban wetland rehabilitation and dolphins.
