Repti-bark, coco husk, and cypress mulch all basically look like mulch anyway... anyone mulch the garden with them after the snake's done with them? (If so, do you do it with chunks of poop/urate in there too?) How about aspen, besides not looking as nice? Presumably if these things are fine for the snake to live in, they're fine for the garden afterward, right?
If so, what do you do with when the ground is covered in snow? Leave it in a pile somewhere and spread it around later when the snow's gone?
