Year-old mulch?

It should be fine unless there is visable mold growing on it in the bag. I'd open it up, spread it out on a plastic tarp and let it dry out before using it though.

I'd use it. When it breaks down, call it humus. If you really want longevity, consumers reports just did a write up on rubber mulch. It looks like bark, and they like it.

I've used finely ground bark mulch in the soil to loosen up heavy clays, which might not be one of your problems. Anyway, it lasts longer than peat, and doesn't fluff up to deceive you about the volumn.

I saw a link to that rubber mulch - sounded good, oh, think, a good way to get those tire heaps diminshed... except that the idea turns me off.

Me too, but you gotta do something with the stuff.

I don't like the idea of it, either. I'm sticking with something more organic.

The problem with rubber is you can't put organic in your garden, unless you scrape off all the rubber and reapply it. I prefer grass clippings and mulched leaves.

I also go up to the Univ. of Md. and get some horse manure.

Let's let commercial enterprises use the rubber mulch and stick to regular mulch at home.

Around these parts the zoo fundraises by selling Zoo Doo, which is composted "waste" from the appropriate denizens...

Ah, really? I should check out if the Albuquerque zoo does that..

Well, actually, I should check out the zoo in the first place. I've been here three months now and not been to the zoo yet.
