That is one reason why I store it for some time, at least two years, before use. Though many people now regard introduced fungus as generally more useful than harmful.

That's a good idea, but it is best to compost manure fist, that helps get rid of an bad things in the bedding, stops the bedding lowering the nitrogen in the soil, and stops strong manure over feeeding or burning plants.

@Fernapple
The stuff I use is composted and sold at garden centres ready for the garden. I don't have an ideal area to compost if I did I would go visit the farmers and pick it up for free. Several people gave me testimonies of how well chicken shit makes their garden grow.
You're right about raw manure in the garden it will burn the plants.

@flower_nut I fully plan to seek out a horse stable or two that might allow to take it off their hands for free, but that is a long term project, as yes, it needs plenty of time to age. I have only just started composting in the past 3 months....bought a yard with a small house attached ? last May.

@MikeInBatonRouge
You need a sunny spot for composting and all my spots have plants.
Leftover rubbish and leaves from our landscape are piled in the woods. After a couple years I use it to plant gardens in the woods. The seeds from the garden rubbish grow in the compost pile. It does break down enough to go through a 1/2 inch mesh.
Have fun with your garden. It's so exciting!

Yes I do that too. This was just a special one off.

It is called rose replants disease in roses, and no one is sure but a fungus or two may be to blame. That is why I store the potting compost a year or two before use.

@Fernapple thnx

@MikeInBatonRouge That ok happy growing.

Yes, plus some loam.

Yes I use that most years, this was just a special one off. It does not pay to mix potting compost with garden compost as it slows/stops heating.
