Now is the time to fertilize your garden for the spring. You shouldn't really wait until spring to do the fertilization with manure.
I have a 16ft x 12ft x 3ft deep pile of sheep mess to get out of a stall. You can haul some of it off for a garden if you want to load up. I do not load it for you, I'm only shoveling all that a single time!! lol
There are so many earthworms it is amazing stuff. I do not promise it is organic or anything, the sheep do get Farm Crest sheep pellets from Tucker Milling and once in a while I worm them with Corid or Fenbendazole.
