If you have a compost heap then I would layer it in the heap, it will

Otherwise I'd bag it and leave it a few months.


That's good advice, just to kill of all the grass seed.

I don't think that grass seed will rot down very quickly. 10 years? Nettles
10 years? I don't know this as fact. But I read it in this group that some
seeds can lie dormant, even in a compost heap for decades.

Depends a lot on whether it's a hot heap or a cold one, IWHT. I've
measured well over 60 deg C in a hot 'dalek' and grass clippings reduced
to ash.

We are talking about seed, not clippings. Also 60c would not reduce them to
ash, would it? Would that temperature kill seed?

If there was ash I suspect the heap spontanesly caught fire, like
some of the bales of haylidge put out around here for the sheep can
do if the sheep are a bit slow in eating it/breaking the bale apart.

I suspect 60 C is hot enough to kill some seeds but probably not all.
Upper 70's to 80 C probably would make everything non-viable.
