I have been saving used coffee grounds for the garden. However, we live in the Midwest, so I need to store them until Spring. How do I store them so they don't get moldy?

Michelle,
I like Beth's idea of using a covered plastic container like a 5-gallon bucket in the garage (or next to the backdoor) to store coffee grounds over winter. Depending on how you use them, you could also portion some of them up using leftover plastic bags, or you might consider composting them along with your kitchen scraps. If you do decide to add other compostable items in with the grounds, keep in mind that coffee grounds are considered a source of nitrogen and fit into the "green" category when referring to the ideal ratio of composting half "green" and half "brown" materials.
Coffee grounds do make an excellent soil conditioner when fully composted and worms love them. They add texture to the soil's structure and a small amount of nitrogen to the soil. If you are saving them to feed to acid-loving plants, keep in mind that spent grounds actually have a more neutral pH than most people realize (most of the acid is stripped from the grounds in the brewing process and ends up in the coffee).
Good luck!

I have an old rubbermaid garbage can that I keep in the garage that I put all of my compostable waste in over the winter. It has a snap-lock lid so critters can't get into it. By the spring, it's mostly full of ready-to-compost scraps.
It's moisture that causes the mold so either dry them in the oven or freeze them, if there's a fisherman in the family and you have a worm bed put some grounds on/in the bed, the worms will be fiesty as heck,,,too much caffine :-)
If you let them dry out before putting in a container, they shouldn't mold.
I am dumping them right on the snow in the flower bed. Is that a problem? That's what I have been doing!
I cut the leg off of a pair of panyhose, and stored the grounds in there. I hung it in the garage
I just throw my used coffee ground out with the filter even if it is winter. I want them to decompose before spring. Also, I want the filter to decompose before spring. I"ve been doing this for several years, and it works fine for me.

I put coffee grounds by the 5 gal bucket in my compost bin and vermicomposter year round. I only garden organically and have for over 20 years. I've had no trouble with mold on my houseplants, but I use "live" soil. All organic and no commercial fertilizer. I also use Bokashi "juice" as a fertilizer with excellent success.
