I always understood you should not cover the tops. Then I watched
Alan Titchmarsh, when he was doing GW, plant some big ones to enter in
a show, and he covered the corms.
The top of the corms is concave, and maybe water can collect there and
cause rot.
Another thing to watch out for, is vine weevil grubs. I have lost
corms overwinter, finding just a shell, with a few vw grubs inside.

Thanks Pam,
I did not know about vine weevil grubs.
