I had a strawberry verte cutting that molded (along with its sister).  I tried everything to save it, but had to keep cutting it back.  Finally, I cut it back to about 1.5 inches, with one node left above ground, and planted it with no roots.  It has a green bud on the node, but it hasn't changed in a month.

Today I got a nice surprise.  The node did not sprout, but something else did!  I don't know if it will make it, but it has a shot.  I still don't see roots.
