Garden waste bin stinks of manure/sewage

[Bearg]

Any ideas why this could be? All we put in there is grass cuttings and leaves/twigs etc. Definitely no animal waste! We've cleaned out the bin with water (didn't want to put chemicals in there) and left it open to air and it still smells awful 🤢

Its just what cut grass and odds and ends do when they are damp...I always regret leaving a trug of weeded stuff around for a while, if it rains then I know it will smell vile at some point!

Oh really? I've had a garden waste bin for years and it's never smelt like this - it really does just smell like poo to be honest! Can't even blame a hot summer for it!

Think about what manure is - chewed up grass.

Comfrey and nettles (for example) can be made into plant feed by letting them rot down in water for a few weeks. It works well but smells truly horrendous. So if your bin has nettles and water in it, and is maybe in the sun, then it is likely to be proper stinky!

It's probably the cold that is causing it - different mouldering cultures surviving at this temperature, not getting the job done as quickly as if it was warmer. All very annoying. It'll sort itself out hopefully. Ours hasn't gone that way this year but we've seen smelt it in the past

Get a garden fork in it and mix it up.

OK thank you, I'm feeling a bit more reassured that we don't have actual manure in our bin somehow 😅

Clumps of damp grass can lead to vile smells IME - not so bad if it can be mixed up with other stuff and/or dried out a bit.
