Cutting back cannas
Well...we had our first killing freeze here (Dallas area) last night. It got down around 25*, so, as expected, my cannas and hymenocallis got zapped.
What I need is for someone to refresh my memory: when cutting back the cannas, how far down do you cut them? I seem to vaguely recall something about cutting them about 2" from the ground...or is it all the way to the ground? Should they be mulched after cutting, even though our ground rarely, if ever, freezes here?
TIA for any info...
