I'd add a 2(a) before number 3 in sfrose's list: try to sell it in the nursery. A couple of times I've sold just a nubbin that was left after careless snipping. PT Barnum's alleged saying about a sucker being born every minute seems to apply to the customers of the nursery as well.

Once I had to drop the price quite a lot but a couple of other times they sold at the full price. A couple of other times they didn't sell at all, though.
