I recently posted a different thread about a sucker in a Royal Frost Birch -- I'm a little cautious about that one because of the threat of birch borer.

But do I have anything to fear about a sucker on a Kwanzan Cherry? Are they hearty enough that I can just whack that thing? Or is it safer to wait until the growing season is over? I know it's not a big deal to wait, but it's really starting to bug me!

FYI -- it's down at the base of the tree, sticking out of the mulch.
