I bought some steer manure from Home Depot last year. It came in bags. I was not able to use it last year and the bags are unopened so am wondering if I can use it this year. I stored it outdoors and the bag rips very easily. Also the manure is green from inside. Wondering if I should use it in my vegetable raised bed or fruit trees or for general landscaping.
I can't see any reason why you shouldn't use it anywhere you want to - the green growth is likely algae, which will grow in damp conditions in daylight or sunlight inside the bag. Home Depot seems to sell a combination product of steer manure mixed with organic compost, so maybe that's what you've actually got - either way, the steer manure should be well aged by now. You may need to let it dry out a bit so that it spreads more easily.
I agree that the bag of manure is just as good now as it was last year. I sometimes find that there is really not much manure in there and that it is a lot of other material. I like to go to a local farmer and get manure and then let it sit for a year or two to rot and decompose and I have excellent luck with it. Just don't get fresh manure and use it right away - will burn all your plants.
