I don't know if anyone else does this but I cut the flower spikes as above, then I lay them straight onto a seed tray filled with compost, so when the seeds fall out from the seed heads straight into the tray, germinate and then prick out into pots to 'over winter'.
When all done all I have to do is remove the withered stems onto the compost to recycle.
Works every time. Hope this helps others.
