Mulching with leaves with seeds?

Last year, I used maple leaves as winter mulch and pulled gazillions of maples this year... any way I can continue to use maple leaves without causing this problem?

What will happen if I mix the leaves with some Johnson Su compost I'll have ready and leave to ferment à la Korean Natural Farming to make a sort of leaf bokashi?

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.
