Fish Waste for Plants

Don’t throw aquarium water away! Use it to water your plants!

When you change the water in your aquarium or fish bowl, why pour it down the drain? It’s rich in nutrients from fish waste and can be used to water both your houseplants and garden plants, giving them a bit of a beneficial organic fertilizer.

Garden writer and blogger, author of 65 gardening books, lecturer and communicator, the Laidback Gardener, Larry Hodgson, passed away in October 2022. Known for his great generosity, his thoroughness and his sense of humor, he reached several generations of amateur and professional gardeners over his 40-year career. Thanks to his son, Mathieu Hodgson, and a team of contributors, will continue its mission of demystifying gardening and making it more accessible to all.
