Storing Grass Clippings?

Hello Folks

I'm getting about 5 bags of clippings a week from a friend and want to store them for later use.

If I leave them in the bag they are steamy and hot within about 2 days, if I spread them out they dry in clumps in about the same period.

Obviously I could put them in the compost heaps but I wondered if there were any other ways to store them to eventually use as layers for the future raised beds?

The only other thing I thought of was to initially mark the beds out then cover with cardboard / grass and install the wooden sides as and when I get them? (I think this will be Vinny's view)

Hi Danny
I wouldn't even bother with the wooden sides. Raised beds don't need wooden boards around hem, in fact they are a pain! I have inherited some but once they totally rot away (which won't be long) I will be doing without any surrounds at all.

Just saying!
