I use bagged mulch all the time. It isn't that bagged mulch is bad, it's how the supplier/manufacturer processed and bagged it. LI Compost here on LI, also known as Hampton Estates mulch, does it right. The only other option here for safe bagged mulch is Scotts, and it's too expensive. I've seen plenty of questionable bulk mulch here too.... it isn't because it's bagged, it's how it's processed. My properties only need 25 cubic foot of mulch at most.... and gates are an issue for bulk mulch. Bags are easier.
