The Best Worm Bedding? The Answer Is A Bunch Of Horse Poo!

Aged horse manure is the best natural bedding and habitat for composting worms.  Red Wigglers have many names, manure worms being one of them….maybe an indication horse manure might be pretty awesome, no?  Not convinced?  Read on.

Dual Purpose

One of the best reasons you should use horse manure as a medium is that it acts as bedding and a ready source of food.  Unlike a straight peat moss habitat, you can head out for vacation knowing you’ve just provided your guys or girls (or “guygirls” since worms are hermaphroditic, right?) a sweet place to hang out AND eat.  Kind of the worm equivalent of wheeling your BarcaLounger, widescreen LCD, and NFL Sunday Ticket into the Old Country Buffet.  Now if vermicomposting your kitchen waste is your objective, you’ll be using it more as a bedding than munchies, but that shouldn’t keep you from listing horse manure as the #1 bedding for your system.

It Doesn’t Smell

Period.  If it does, it’s not aged enough, is still off-gassing ammonia, or it’s mixed with something else stinky.

Extremely Low Cost (like nada.)

Another reason is that it’s free, assuming you don’t go to great expense to collect it.  Though I’m only a few minutes from Philadelphia, I have a small farm and children’s petting zoo within a 5-minute walk from my house.  Lucky, right?  (Even luckier that the owner doesn’t care when I stop by for a load.)

Free Worms!

And I suppose you wouldn’t mind free worms with your free manure, right?  Seriously, my last load of horse manure probably had $60-80 retail value in Red Wigglers, more than paying for the cost of renting the truck from Home Depot.  And those worms in there have been getting it on with other worms, making little babies along the way, something you probably won’t even notice from the end of your shovel.  In fact, I’m reserving one of my beds for an experiment to see if a bed of horse manure will populate itself into a dense population within a year. 

Huge Time Saver

If you take your worm fetish (that’s what my wife calls it) beyond the confines of a Worm Factory 360 or Rubbermaid bin, dumping a load of horse manure in your container, bed or windrow will save you mucho time and hassle in shredding cardboard, egg cartons, newsprint.  My 6 foot high stack of old Amazon boxes will now be repurposed to (shameless plug alert) send you the worms you’re surely about to buy!

But before you run out for your horse doody, follow a couple basic guidelines. 

  1. Make sure the horse manure is aged for at least 3 months.  This is for two reasons.  First, the manure itself must first go through its thermophyllic, or hot stage of composting.  Red Wigglers get really grumpy above 90F, slowing down eating and hooking up with each other (note to self: create Tinder App for worms) and your composting horse manure can reach 150F, giving another  meaning to the term, “hot shit.”  Secondly, the horses are probably given deworming medicine several times per year.  While you can still use this manure, the deworming agent present in the medicine MUST be given time to break down.  Pro tip: If you find worms present in the horse manure, you’re good.
  2. Ask the owner for permission!  Shotguns and electric fences are no fun!  🙂

Now the next step is finding your source.  And you won’t need much.  In fact, if you’ve ever seen a parade, you’ve seen a horse drop a pretty impressive load right in front of you.  Just a single horse’s, um, “output” will give you more than you need.  It’s just a matter of having the courage to ask to take it.
