I'm spreading my pile out on the garden beds now; a thin layer of mowed leaves, manure on top...repeat. I'm too busy with seedlings and the veggie garden to get the flowerbeds done in the spring...plus, it's just too buggy to enjoy doing it then.
I made another straight manure bed for some end-of-season sale plants that I got for a song. Their planting spots aren't ready yet and the dead trees won't be removed 'til late winter to free up the area, so this will carry them over nicely, I think. They're loving it so far.
