: I have a clump of crocosmias (similar to Lucifer but not so vigorous)
: that is infested with grass. As the leaves have pretty much browned
: back, can I dig up and clean the corms now, dry them out and store
: them, with the intention of planting them elsewhere next spring?

Yes you can but better to clear the ground and put them right back in. I
think they will survive anything. I try and get rid of as many as possible
each year but still they come!
