I know this was posted a couple of years ago, but I'm wondering if there's been any follow up or any new posters that are using coal for landscaping instead of wood mulch? I love the look of black, absolutely will NOT use dye and am hearing horror stories about wooden mulch. Cocoa mulch also gets moldy if it's wet too long. So what's the story on using coal in flower beds pea sized. Anyone?

One of the issues I see is that fresh shiny coal will get a dull film on it over time. It may also get a bluish tint over time, it's similar to the color you might see when oil is on water.
You may even be able to get blue coal if you wanted it. You'd find this anywhere where a lot of water is dripping onto the same pieces of coal for a very long time. For example over at Hudson they have pockets and the coal goes across a screen with water jets. A lot of coal ends up on the ground under the chutes and it always has water going on it and it gets that blue tint.
