normally you pile it up and let it rot for at least 6months to a year, separate to the normal compost bin. then dig it in or lay it as a mulch around the plants.

let it rot for 6 months to a year then either dig it in or use it as a mulch. I personally wouldn't put it on a normal compost bin.

I'd let it rot for at least a year before using and, as said above, don't add to your actual compost bin.

I thought you could add a small layer of fresh horse manure to a composter to act as an accelerator; it is nitrogen rich and encourages the biological decomposition.
After all, Flowerdew always wees on his compost.

So does Bulba, but I wouldn't add fresh horse manure to compost personally.

There's a big difference between urine and faeces, Buddleja.. as far as I'm concerned, manure needs to be composted on its own, preferably with straw mixed in.

Bamboo, I think I know that urine and dung are different things from personal experience every day!

Most horse manure often comes from stables where the animals urinate on the straw and dung.

The reason for not including manure in a standard compost bin is that temperature never reach the level where the seeds are killed, and horses have inefficient guts that pass these through undamaged. It is not unusual to see manure piles sprouting with oat and weed seedlings.

If you can live with the weeds coming up from the compost then there is no other reason for not incorporating it into garden compost.

Why add weed seeds to your garden Buddlejar...as that i where they will end up. The compost certainly won't kill them unless you can hot compost, which most of us composting at home can't.
