I live in Etobicoke and we have just done some work on our front steps. There is left over concrete, cinder blocks and brick. I was thinking of repurposing this material into a rain garden for my front garden (none of the plants would be eaten) however I’m just wondering about if I should be concerned about using these materials? If so, what are your suggestions for a rock/rain garden?
Thank you for contacting Toronto Master Gardeners.
The Toronto Region Conservation Authority has prepared a detailed “how to” on rain gardens which should answer your questions on rain gardens.
Depending on aesthetics, you may be able to use some of the materials you have left over to manage water overflows in your rain garden.
