Good to know, going to try that with ash tree leaves then. Could do with them.
Must be possible to incorporate them in a hot compost, to kill the seeds. There have been quite some composting leave thread. Good luck.
It does really bother me because I just use the seedlings as more mulch. But I would think fermenting them would do the trick. Also, I've heard of boiling them, but for some reason large amount, that might not be feasible.
